Hereinafter, a method, an apparatus, a computer-readable storage medium, and a computer device for processing model information provided by embodiments of the present application will be described in detail respectively. The numbers in the following examples are not intended to limit the order of preference of the examples. The ambient light shielding (AO) in the embodiment of the present application describes an effect of shielding ambient light when an object intersects or approaches the object, and may be used to control the intensity of indirect illumination received by the model surface.

Fig. 1 is a schematic flowchart of a model information processing method provided in an embodiment of the present application, where the model information processing method includes the following steps.

101, obtaining an object model to be processed, wherein the object model comprises a plurality of vertexes.

The object model to be processed may be any model for which it is desirable to generate ambient light mask information.

For example, the object model may be a tree crown model or a shrub-like model, or the object model may be a model made by grid-plugging. In order to achieve a better ambient light shielding effect and also consider the problems of efficiency and accuracy, the target model can be a tree crown, shrub and other models made by grid insert, and even a tree crown, shrub and other models made by grid insert which only need to add a small amount of macroscopic ambient light shielding effect.

FIG. 2 is a schematic diagram of a tree crown model made by grid plugging sheets.

The tree crown, shrub and other models manufactured by the grid insert sheet can meet requirements without a large number of auxiliary spheres (described later), the calculation efficiency is improved by fewer auxiliary spheres, and the adjustment efficiency of the auxiliary spheres is improved by fewer auxiliary spheres without more adjustment; in addition, in the application, the calculated intensity value of the ambient light shielding needs to be stored in the vertex color of the model, so that more vertexes are needed to ensure the accuracy of the ambient light shielding, and the number of vertexes of the tree crown-shaped model, the shrub-shaped model and other models manufactured by the grid insert sheet can well meet the requirements.

The target model can be stored by using model variables, the target model comprises a vertex list, the vertex list comprises a plurality of vertexes, each vertex has a corresponding vertex color attribute, and the target model is stored by using the model variables so as to modify the vertex colors of the vertexes subsequently. And determining whether the target model is acquired or not through the model variable, if the model variable is empty, indicating that the target model is not acquired, and prompting, otherwise, indicating that the target model is acquired. The vertex color is an attribute of a vertex of the target model, and can be obtained in a corresponding material when the target model is rendered in a game and used for calculating the vertex color in a user-defined mode.

In an embodiment, the target model may be set in advance, so as to directly obtain the set target model, or the target model may be obtained by other means.

And 102, acquiring auxiliary spheres corresponding to the target model, wherein the auxiliary spheres comprise at least one auxiliary sphere which is predetermined according to the outline of the target model.

The auxiliary sphere is a sphere model provided to assist in determining the ambient light shielding information of the target model, and the auxiliary sphere corresponding to the target model includes at least one, such as one or more. The auxiliary sphere determines information such as distribution, central point and range of the ambient light shielding information of the target model. For example, the distribution of the ambient light shielding information of the target model can be determined according to the distribution of the auxiliary spheres, the center points of the ambient light shielding information of the target model can be determined according to the centers of the auxiliary spheres, wherein one center corresponds to one center point, and the range of the ambient light shielding information of the target model can be determined according to the radius of the auxiliary spheres.

The auxiliary sphere of the target model may be predetermined, for example, according to the contour of the target model. The determination may be automatic or manual according to the user's requirement, and will be described in detail below. And storing the determined auxiliary sphere into a list variable of an auxiliary sphere list, wherein if the list variable is empty, the auxiliary sphere of which the target model is not determined is represented, and if the list variable is not empty, the auxiliary sphere of which the target model is determined is represented.

Wherein the contour of the object model comprises an overall contour and/or a partial contour. Correspondingly, one auxiliary sphere is preset for the overall contour of the target model, i.e. one auxiliary sphere is corresponding to the overall contour, and/or one auxiliary sphere is preset for each partial contour, i.e. one auxiliary sphere is corresponding to each partial contour. The corresponding auxiliary sphere will include/wrap the outline corresponding to the predetermined scale.

For example, when the target model is a crown-shaped model or a shrub-shaped model, the contour of the target model includes an overall contour and/or at least one branch and leaf cluster contour, and one or more branch and leaf cluster contours may be included in one target model. The auxiliary sphere of the target model comprises an auxiliary sphere corresponding to the overall outline and/or an auxiliary sphere corresponding to each branch and leaf cluster outline, the auxiliary sphere corresponding to the overall outline at least comprises/wraps the overall outline at a first preset proportion, and the branch and leaf cluster outline at least comprises/wraps the branch and leaf cluster outline at a second preset proportion. The first preset proportion and the second preset proportion may be the same or different, for example, the first preset proportion is 90%, and the second preset proportion is 85%.

The auxiliary sphere corresponding to the overall contour can be used to determine the overall ambient light shielding effect of the target model, and the auxiliary sphere corresponding to the partial contour can be used to determine the ambient light shielding effect on the internal details of the model.

Fig. 3 is a schematic diagram of an auxiliary sphere provided in the embodiment of the present application. The auxiliary spheres in fig. 3 correspond to the auxiliary spheres corresponding to the crown-shaped model shown in fig. 2, wherein the number of the auxiliary spheres corresponding to the crown-shaped model is three, and the three auxiliary spheres are respectively the auxiliary Sphere corresponding to the overall contour and the two auxiliary spheres corresponding to the contours of the two branch and leaf clusters, as shown in the lower right corner, and correspond to Sphere001, sphere002 and Sphere003.

For each vertex of the target model, a target auxiliary sphere matching the vertex is determined from the auxiliary spheres 103.

Traversing all vertexes of the target model, acquiring information such as world space coordinates of the vertexes, and sphere center coordinates (the sphere center coordinates are world coordinates) and radiuses corresponding to the auxiliary spheres and the like for each vertex of all vertexes, and determining a target auxiliary sphere matched with the vertex from the auxiliary spheres according to the world space coordinates, the sphere center coordinates and the radiuses of the vertexes. And one vertex matched target auxiliary sphere corresponds to one vertex matched target auxiliary sphere.

In one embodiment, as shown in FIG. 4, step 103 includes steps 201 through 202.

Candidate auxiliary spheres are determined 201 from the auxiliary spheres according to the bounding box of the target model.

The bounding box of the target model refers to a cube or a two-dimensional rectangle capable of containing the target model, and is one kind of bounding volume, the target model in this embodiment is a three-dimensional model as an example, therefore, the bounding box of the target model refers to a cube capable of containing the target model, for example, the bounding box is an axis-aligned bounding box, and in other embodiments, other matching bounding boxes may be selected.

Wherein an Axis aligned bounding box (AABB bounding box) is defined as the smallest hexahedron containing the object model with sides parallel to the coordinate axes. In one embodiment, the bounding box is a cuboid shaped, axis aligned bounding box. The axis alignment bounding box of the cuboid shape is simple in structure, only six scalars are needed for describing the axis alignment bounding box of the cuboid shape, and the storage space is small.

In an embodiment, the step of determining candidate auxiliary spheres from the auxiliary spheres according to the bounding box of the target model specifically includes: acquiring a bounding box of a target model; and determining auxiliary spheres with the sphere centers of the auxiliary spheres within the bounding box of the target model as candidate auxiliary spheres.

The bounding box of the target model is determined by the maximum value and the minimum value of the coordinates of the three coordinate axes in the local coordinate system corresponding to the target model. Wherein the bounding box of the object model is retrievable via an interface, such as the interface provided by MaxScript.

After the bounding box of the target model is obtained, converting the world coordinates of the center of the auxiliary sphere into local coordinates in a local coordinate system of the target model, comparing the local coordinates of the center of the auxiliary sphere with coordinates corresponding to the bounding box, if the local coordinates of the center of the auxiliary sphere are compared with the maximum value and the minimum value of the axial coordinates of the three coordinates, if the local coordinates of the center of the auxiliary sphere are all between the maximum value and the minimum value, determining that the center of the auxiliary sphere is in the bounding box of the target model, and otherwise, determining that the center of the auxiliary sphere is not in the bounding box of the target model, skipping the auxiliary sphere, thus obtaining the candidate auxiliary spheres in all the auxiliary spheres.

The candidate auxiliary sphere can also be represented by a candidate auxiliary sphere list, if the candidate auxiliary sphere list is empty, it means that the sphere centers of all the auxiliary spheres are no longer in the bounding box of the target model, and then prompt is performed without performing subsequent steps.

In the step, the bounding box of the target model is used for determining the candidate auxiliary ball body so as to remove the auxiliary ball body which is not in the bounding box of the target model, avoid the influence of the auxiliary ball body which is not in the bounding box of the target model on the ambient light shielding effect, and improve the rationality and the accuracy of the ambient light shielding effect.

And 202, determining a target auxiliary sphere matched with the vertex from the candidate auxiliary spheres according to the position relation between the vertex and the candidate auxiliary spheres.

After the candidate auxiliary spheres are determined, for each vertex of the target model, a target auxiliary sphere matched with the vertex is determined from the candidate auxiliary spheres according to the position relation between the vertex and the candidate auxiliary sphere. The position relation comprises that the vertex is positioned inside the candidate auxiliary sphere, the vertex is positioned outside the candidate auxiliary sphere and the like.

In one embodiment, the step 202 includes: when the vertex is in at least one candidate auxiliary sphere, determining a first distance between the vertex and the sphere center of the candidate auxiliary sphere, and taking the candidate auxiliary sphere with the minimum first distance as a target auxiliary sphere matched with the vertex; when the vertex is outside all the candidate auxiliary spheres, determining second distances between the vertex and the surfaces of all the candidate auxiliary spheres, and taking the candidate auxiliary sphere with the smallest second distance as a target auxiliary sphere matched with the vertex.

When the vertex is inside at least one candidate auxiliary sphere, the smaller the first distance between the vertex and the sphere center of the candidate auxiliary sphere is, the larger the influence of the candidate auxiliary sphere on the ambient light shielding information of the vertex is, the candidate auxiliary sphere with the smallest first distance is taken as the target auxiliary sphere of the vertex, and when the vertex is outside all the candidate auxiliary spheres, the smaller the second distance between the vertex and the surfaces of all the candidate auxiliary spheres is, the larger the influence of the candidate auxiliary sphere on the ambient light shielding information of the vertex is, and the candidate auxiliary sphere with the smallest second distance is determined as the target auxiliary sphere of the vertex.

In one embodiment, the vertex is inside the candidate auxiliary sphere and can be represented by the distance between the vertex and the sphere center of the candidate auxiliary sphere being smaller than the radius of the sphere, and correspondingly, the vertex is outside the candidate auxiliary sphere and can be represented by the distance between the vertex and the sphere center of the candidate auxiliary sphere being larger than the radius of the sphere, wherein the vertex on the surface of the candidate auxiliary sphere can be listed as the vertex inside the candidate auxiliary sphere or the vertex outside the candidate auxiliary sphere.

Correspondingly, as shown in fig. 5, the step 202 includes the following steps 301 to 310.

301, a first candidate auxiliary sphere is obtained from the candidate auxiliary sphere list as a temporary target sphere.

302, whether there are any more candidate auxiliary spheres in the candidate auxiliary sphere list that have not been acquired.

If there is no candidate helper sphere that has not been acquired, i.e. all candidate helper spheres in the list of candidate helper spheres have been acquired, step 303 is executed, otherwise, there is a candidate helper sphere that has not been acquired, step 304 is executed.

And 303, taking the temporary target sphere as a target auxiliary sphere matched with the vertex.

And when all the candidate auxiliary spheres in the candidate auxiliary sphere list are acquired, taking the temporary target sphere as the target auxiliary sphere matched with the vertex.

And 304, acquiring the next candidate auxiliary sphere from the candidate auxiliary sphere list as the current sphere.

305, the distance between the vertex and the center of the temporary target sphere?

I.e. whether the distance between the vertex and the sphere center of the temporary target sphere is smaller than or equal to the radius of the temporary target sphere, if yes, it means that the vertex is inside the temporary target sphere, step 306 is executed, otherwise, step 308 is executed.

306, the distance between the vertex and the center of the current sphere, < = current sphere radius?

That is, whether the distance between the vertex and the sphere center of the current sphere is smaller than or equal to the radius of the current sphere, if so, the vertex is inside the current sphere, that is, the vertex is both inside the temporary target sphere and the current sphere, and step 307 is executed; otherwise, i.e. the vertex is inside the temporary target sphere and outside the current sphere, then step 302 is performed.

And 307, taking the candidate auxiliary sphere with smaller distance between the vertex and the sphere center of the current sphere and the distance between the vertex and the sphere center of the temporary target sphere as the temporary target sphere. Step 302 is then performed.

308, the distance between the vertex and the center of the current sphere < = current sphere radius?

I.e. whether the distance between the vertex and the sphere center of the current sphere is smaller than or equal to the radius of the current sphere, if so, it means that the vertex is inside the current sphere, i.e. the vertex is outside the temporary target sphere, and inside the current sphere, step 309 is executed; otherwise, i.e. the vertex is outside the temporary target sphere and also outside the current sphere, step 310 is performed.

Although step 306 is the same as step 308, after step 305 is combined, step 306 is different from step 308 in the purpose to be achieved.

309, the current sphere is taken as the temporary target sphere. Step 302 is then performed.

And 310, taking the candidate auxiliary sphere with smaller distance between the vertex and the surface of the temporary target sphere and the distance between the vertex and the surface of the current sphere as the temporary target sphere. Step 302 is then performed.

Through the above steps 301 to 310, it is realized that the target auxiliary sphere matching the vertex is determined from the candidate auxiliary spheres according to the position relationship between the vertex and the candidate auxiliary sphere.

In an embodiment, instead of determining candidate auxiliary spheres separately, each auxiliary sphere may be obtained from the auxiliary sphere list, and then determine whether the center of the auxiliary sphere is within the bounding box of the target model, if not, obtain the next auxiliary sphere from the auxiliary sphere list, if the auxiliary sphere is within the bounding box of the target model, then use the auxiliary sphere as a temporary target sphere, and if there is an unacquired candidate auxiliary sphere in the auxiliary sphere list, obtain the next auxiliary sphere from the auxiliary sphere list, determine whether the center of the auxiliary sphere is within the bounding box of the target model, and if the auxiliary sphere is within the bounding box of the target model, then use the auxiliary sphere as a current sphere, and then perform the corresponding steps between 305 and 310 until each auxiliary sphere in the auxiliary sphere list has been obtained. It is understood that, in this embodiment, after obtaining the auxiliary spheres from the auxiliary sphere list, it is determined whether the centers of the auxiliary spheres are within the bounding box of the target model, and if so, other determinations are performed, as compared to determining candidate auxiliary spheres from the auxiliary sphere list in advance and then determining the target auxiliary sphere from the candidate auxiliary sphere list, and the latter (i.e., determining candidate auxiliary spheres from the auxiliary sphere list in advance and then determining the target auxiliary sphere from the candidate auxiliary sphere list) is more efficient and faster.

Step 103 above realizes determining the target auxiliary sphere matching with the vertex from the auxiliary spheres.

And 104, determining the ambient light shielding information corresponding to the vertex of the target model according to the radius of the target auxiliary sphere and the distance between the vertex and the spherical center of the target auxiliary sphere.

After the target auxiliary sphere is determined, the ambient light shielding information corresponding to the vertex of the target model is determined according to the distance between the vertex and the target auxiliary sphere. For example, the radius of the target auxiliary sphere is obtained; and determining the distance between the vertex and the sphere center of the target auxiliary sphere, and determining the ambient light shielding information corresponding to the vertex of the target model according to the radius of the target auxiliary sphere and the distance between the vertex and the sphere center of the target auxiliary sphere.

The method comprises the steps of determining the distance between a vertex and the center of a target auxiliary sphere according to the world coordinates of the vertex and the world coordinates of the center of the target auxiliary sphere, determining the distance between the vertex and the center of the target auxiliary sphere, and determining the ratio of the distance to the radius as the ambient light shielding information corresponding to the vertex of a target model after the radius of the target auxiliary sphere is obtained. The ambient light mask information includes an ambient light mask intensity value, for example, a ratio of a distance to a radius is directly determined as an ambient light mask intensity value corresponding to a vertex of the target model. Wherein, in one view, the radius of the target auxiliary sphere can be understood to be used to normalize the distance.

When the ratio of the distance to the radius is larger than the preset ratio, the preset ratio is determined as the ambient light shielding strength value corresponding to the vertex of the target model. The preset ratio may be set to 1, or other reasonable values, such as 0.9. It is understood that the distance to radius ratio is truncated to a preset ratio, such as 1.

Therefore, the intensity value of the shielding of the ambient light from the center of the target auxiliary sphere to the spherical surface is uniformly increased from 0 to 1, a gradual change ambient light shielding effect can be generated, meanwhile, the central point of the ambient light shielding effect is determined according to the center of the target auxiliary sphere, and the range of the ambient light shielding effect is determined according to the radius of the target auxiliary sphere; and if the vertex is positioned outside the target auxiliary sphere, the influence on the ambient light shielding intensity value is not generated.

The smaller the ambient light shielding intensity value is, the lower the degree of the surface near the corresponding vertex receiving ambient light is, the darker the surface of the target model is under the condition of unchanged degree of receiving direct light, and when the ambient light shielding intensity value is 0, the condition that the position corresponding to the vertex does not receive the ambient light is indicated; the larger the ambient light shielding intensity value is, the higher the degree of ambient light received by the surface near the vertex is, and the brighter the target model surface is under the condition of unchanged direct light irradiation degree, and when the ambient light shielding intensity value is 1, it is indicated that the position corresponding to the vertex receives the ambient light of full intensity and is not influenced by ambient light shielding.

In the embodiment of the application, the ambient light shielding information of the target model is not required to be determined according to the form of the surface of the model, such as curvature, normal and the like, so that a better ambient light shielding effect can be achieved no matter how the state is simplified or abstracted, and the ambient light shielding information is determined according to the radius of the target auxiliary sphere and the distance between the vertex and the spherical center of the target auxiliary sphere, so that the determined ambient light shielding information is related to the distance between the vertex and the spherical center of the target auxiliary sphere, a soft gradually-changed ambient light shielding effect can be generated, and meanwhile, the central point and the range of the gradually-changed ambient light shielding effect are respectively determined according to the spherical center and the radius of the target auxiliary sphere, and the ambient light shielding effect of the target model is improved.

The solution in the embodiment of the present application can be integrated into a model information processing tool (such as a vertex color automatic rendering tool) based on a digital content production tool or a digital content production application, such as 3dsmax. It is understood that the model information processing means in the embodiment of the present application, in which the model information processing method in the embodiment of the present application is integrated, may be developed/integrated in 3dsmax, or that the model information processing method in the embodiment of the present application is executed by the model information processing means.

The target model comprises a plurality of vertexes.

A plurality of controls are displayed on the interactive interface, such as a SELECT TREE control, an AO Visible control, an AO Spheres control, an ADD control, a PAINT → AO control and the like, and corresponding functions are realized through corresponding controls, which are correspondingly introduced later.

The step of setting the target model to be processed comprises the following steps: and displaying an interactive interface through a graphical user interface, and setting a target model to be processed through a model selection control on the interactive interface. Wherein the model selection control is a SELECT TREE control in fig. 7.

Further, the step of setting the target model to be processed includes: displaying an interactive interface through a graphical user interface, wherein a model selection control is displayed on the interactive interface; responding to the trigger operation aiming at the model selection control, and displaying a model selection interface; and determining a selected target model based on the model selection interface, taking the selected target model as a target model to be processed, and further displaying the target model to be processed through a graphical user interface.

The trigger operation may be a click operation, a double click operation, a right click operation, a touch operation, and the like for a model selection control, such as the SELECT TREE control in fig. 7, or may also be other trigger operations, such as a voice trigger operation, and the like, for example, when a voice including "SELECT a model" is detected, it is determined that the model selection control is triggered. The triggering operations of other controls in the following text are similar to this, and will not be described in detail again.

In response to a trigger operation for the model selection control, a model selection interface is displayed, through which a target model to be processed can be selected/set from the computer device, as in fig. 7, the currently selected target model to be processed is a model with a model name SM _ Tyro _ Tree _ 13.

The model variable Tree may be added to the MaxScript code, the target model is loaded and stored in the model variable Tree, and the target model is rendered and then displayed through a graphical user interface, such as the target model shown in fig. 2.

In the embodiment, the target model to be processed can be conveniently selected through the model selection control, so that the existing target model can be conveniently processed.

Auxiliary spheres are added 402 to the object model, the auxiliary spheres comprising at least one, the auxiliary sphere being determined from the contour of the object model.

Wherein, the step of adding an auxiliary sphere to the target model comprises: and displaying an interactive interface through a graphical user interface, and adding an auxiliary sphere for the target model through an adding control on the interactive interface. Wherein the ADD control is an ADD control in fig. 7.

Further, the step of adding an auxiliary sphere to the target model includes: and displaying an interactive interface through a graphical user interface, displaying an adding control of the auxiliary sphere on the interactive interface, and responding to a trigger operation aiming at the adding control to add the auxiliary sphere for the target model. That is, in response to a triggering operation on the ADD control, an auxiliary sphere is added to the target model. Further, the auxiliary sphere is displayed through the graphical user interface when the auxiliary sphere is in a visible state.

The adding of the auxiliary sphere to the target model is specifically to add the auxiliary sphere to the target model according to the contour of the target model. I.e. the determination of the auxiliary sphere is related to the contour of the target model, the determined auxiliary sphere is as expected since the auxiliary sphere is determined according to the contour of the target model.

In one case, the step of adding an auxiliary sphere to the target model according to the contour of the target model includes: and adding an initial sphere for the target model, and adjusting the initial sphere according to the contour of the target model to obtain an adjusted auxiliary sphere. Understandably, after the ADD control is triggered, an initial sphere is automatically added to the target model, and then the initial sphere is adjusted according to the contour to obtain an adjusted auxiliary sphere.

The initial sphere is also a sphere model like the auxiliary sphere, and the initial sphere is automatically generated in the scene. In one case, the initial sphere would be generated at a default generation position with a default radius, e.g., the default generation position being the origin of the world coordinate system, and the default radius being in units of length of 3dsmax, e.g., 100, and the generated initial sphere would be displayed via the graphical user interface. In one case, the generation position and the radius of the initial sphere may also be set.

After the initial sphere is generated, the initial sphere is adjusted according to the contour of the target model. For example, the initial sphere may be adjusted by the panel of attributes of the auxiliary sphere according to the contour of the target model. For example, the radius of the initial sphere is adjusted on the property panel of the auxiliary sphere, and the position of the initial sphere (including the center point of the initial sphere) is adjusted according to the contour of the target model. Adjustments may be made in conjunction with pivot or coordinate parameter values of the target model. Correspondingly, the selected initial sphere is obtained, for example, the initial sphere to be adjusted is selected through the AO Spheres control, the radius, the position and the like set on the property panel of the auxiliary sphere are received, the initial sphere is adjusted according to the set radius and position, and the radius and the position of the initial sphere are adjusted to the set radius and position.

The initial sphere to be adjusted can be selected by selecting the initial sphere, for example, by using an AO Spheres control, and the initial sphere is moved or the radius is enlarged/reduced to achieve the purpose of corresponding adjustment.

And finally, enabling the first auxiliary sphere of the adjusted target model to at least comprise the overall contour of the target model in the first preset proportion, and/or enabling the second auxiliary sphere of the target model to at least comprise the partial contour of the target model in the second preset proportion, for example, the second auxiliary sphere at least comprises the contour of a branch and leaf cluster in the second preset proportion, one contour of the branch and leaf cluster corresponds to one second auxiliary sphere, and the auxiliary sphere of the target model comprises the first auxiliary sphere and/or the second auxiliary sphere.

In this case, an initial sphere is generated first, and then the initial sphere is adjusted according to the contour of the target model to obtain an auxiliary sphere.

In one case, the contour of the target model includes an overall contour and/or at least one branch-leaf cluster contour, and the step of adding an auxiliary sphere to the target model according to the contour of the target model includes: adding a first auxiliary sphere to the target model according to the overall contour of the target model, wherein the first auxiliary sphere at least wraps the overall contour of a first preset proportion; and/or adding second auxiliary spheres corresponding to the number of the branches and leaves to the target model according to the contour of the branches and leaves of the target model, wherein the second auxiliary spheres at least wrap the contour of the branches and leaves at a second preset proportion; and taking the first auxiliary sphere and/or the second auxiliary sphere as the auxiliary sphere of the target model. Further, the auxiliary sphere of the target model may be adjusted to obtain a final auxiliary sphere. When the adjustment is carried out, the auxiliary sphere needing to be adjusted is selected through the AO Spheres control, and after the auxiliary sphere is selected, the adjustment can be carried out on the attribute panel of the auxiliary sphere, or the initial sphere is moved or the radius is enlarged/reduced so as to achieve the purpose of corresponding adjustment.

In this case, the auxiliary sphere may be added according to the contour of the target model, and then the added auxiliary sphere may be adjusted.

The auxiliary sphere after the target model adjustment can be as shown in fig. 3.

In an embodiment, the added auxiliary sphere may also be deleted, for example, a certain auxiliary sphere is selected, and the auxiliary sphere is deleted in response to a deletion instruction for the auxiliary sphere. The delete command may be generated by selecting the auxiliary sphere and clicking the right button.

The number of the auxiliary spheres of the target model is at least one, and when the number of the auxiliary spheres is multiple, the auxiliary spheres can be inserted, contained and separated, namely, the position relation among the auxiliary spheres is not limited and is only related to the outline of the target model.

List variables are added into the MaxScript code, the added auxiliary spheres of the target model are added into the list variables of the auxiliary sphere list, currently, three auxiliary spheres are added to the target model, and correspondingly, the list variables comprise the three auxiliary spheres. As shown in fig. 7 and 2, the names of the three auxiliary spheres are Sphere001, sphere002 and Sphere003, respectively.

In the above scheme, the radius, the central point, the number of the auxiliary spheres and the like of the auxiliary spheres can be changed by adjusting the auxiliary spheres, so that the distribution, the gradually changing central point, the gradually changing range and the like of the ambient light shielding information can be adjusted by adjusting the number, the central point and the radius of the auxiliary spheres, and the distribution effect and the optional gradually changing effect of the ambient light shielding can be realized.

In the embodiment of the application, the distribution effect of the ambient light shielding on the target model is set autonomously by controlling the number and/or the position of the auxiliary spheres, and the gradual change effect of the ambient light shielding can be controlled by adjusting the radius of the auxiliary model, so that the ambient light shielding effect is generated independent of the form of the target model.

It should be noted that, in the current ambient light shielding effect obtained according to the form of the target model, such as curvature, normal line, etc., only one type of similar ambient light shielding effect is generated for one target model, and the distribution of the ambient light shielding effect cannot be adjusted.

In an embodiment, the displaying and hiding of the auxiliary sphere can also be set, for example, the displaying and hiding of the auxiliary sphere is controlled according to a display and hiding control element of the auxiliary sphere. Wherein, the explicit and implicit controls are AO Visible controls in fig. 7. Correspondingly, an interactive interface is displayed on the graphical user interface, a display and hidden control of the auxiliary sphere is displayed on the interactive interface, and the display and/or the hiding of the auxiliary sphere are controlled in response to the triggering operation aiming at the display and hidden control. If the auxiliary sphere is displayed on the current graphical user interface, after the AO visual control is triggered, setting the state of the auxiliary sphere to be an invisible state, and hiding the auxiliary sphere; if the auxiliary sphere is not displayed on the current graphical user interface, after the AO Visible control is triggered, the state of the auxiliary sphere is set to be a Visible state, so that the auxiliary sphere is displayed, and the display effect is shown in fig. 3. The display and the hiding of the auxiliary sphere are controlled to avoid influencing other operations.

And 403, when the vertex color drawing instruction is detected, acquiring the target model and the auxiliary sphere corresponding to the target model.

Wherein, a drawing control on the interactive interface, such as PAINT → AO control in fig. 7, is triggered to generate a vertex color drawing instruction. For example, clicking the PAINT → AO control to trigger the control, generating a vertex color drawing instruction, and acquiring the target model and an auxiliary sphere corresponding to the target model when the vertex color drawing instruction is detected.

For example, a model variable may be obtained, if the model variable is empty, it means that there is no target model, and a prompt is performed, otherwise, it means that a target model is obtained; and acquiring a list variable, wherein if the list variable is empty, the auxiliary sphere is set for the target model, and if the list variable is not empty, an auxiliary sphere list in the list variable is acquired.

For each vertex of the target model, a target auxiliary sphere matching the vertex is determined from the auxiliary spheres 404.

And 405, determining the ambient light shielding information corresponding to the vertex of the target model according to the radius of the target auxiliary sphere and the distance between the vertex and the spherical center of the target auxiliary sphere.

In an embodiment, as shown in fig. 6, the model information processing method further includes the following steps 406 to 407.

And 406, storing the ambient light shielding information into the vertex color of the target model.

For example, the calculated ambient light mask intensity values are saved to the vertex color corresponding to each vertex of the object model.

And 407, rendering the target model according to the vertex color to obtain the ambient light shielding effect of the target model.

When the target model is rendered according to the vertex color, the color value of the corresponding vertex can be obtained in the corresponding material, and the final color value of the vertex is determined according to the color value and the vertex color, for example, the color value of the vertex is multiplied by the vertex color (if the vertex color is, the multiplication is multiplied by 0.2) to obtain the final color value of the vertex. If other pixels are also corresponding to the pixels corresponding to the two adjacent vertexes, the two adjacent vertexes are interpolated to obtain the final color values corresponding to the other pixels. And rendering and displaying after the final color value is obtained.

Fig. 8 is a graph showing a comparison between the ambient light shielding effect obtained by the tool or method in the embodiment of the present application and the ambient light shielding effect obtained in the prior art, wherein the target model used is the model shown in fig. 2. The left side in fig. 8 is an ambient light shading effect graph obtained by using the prior art, such as the ambient light baking calculation (which needs to be calculated according to the model state, such as curvature and normal) in 3dsmax, and the right side is an ambient light shading effect graph obtained by using the tool or method in the embodiment of the present application, where the ambient light shading effect is obtained by rendering the vertex color through the material in the non-area Engine 4.

As can be seen from fig. 8, since the patch arrangement of the model manufactured by the grid insert sheet is disordered, the ambient light shielding effect calculated according to the model form such as curvature, normal line and the like in the prior art is disordered and is not in accordance with the real situation, and the ambient light shielding effect obtained by using the method or the tool in the application is softer and more regular, is in accordance with the real situation, and meets the requirement.

The embodiment of the application can be used for customizing the gradual change ambient light shading effect by a protocol user, and conveniently and quickly appointing the ambient light shading intensity value to the vertex color of the target model.
