Based on the embodiments in this disclosure, all other embodiments that a person skilled in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.

At present, for blueprints of various models, such as virtual models (virtual vehicles and the like) in games, the blueprints of the models are generally generated by a hand-drawn three-view mode, and the hand-drawn three-view mode cannot achieve 360-degree display. In the related art, a blueprint of a model is generally generated by adding a map to the model. Specifically, a UV ray frame of a model is firstly manufactured, then a color (such as blue) is filled in the wire frame, and then the wire frame is added to a material ball of the model. Although 360-degree display can be achieved in the mode, the mapping occupies a large amount of memory, and new mapping is required to be added for later color replacement by hand painting, so that the efficiency is low; in addition, the accuracy of wire frame is lower, and the blueprint that renders will have a large amount of sawtooth generally, and the bandwagon effect is relatively poor, if want better bandwagon effect, and the manufacturing process is comparatively loaded down with trivial details, needs a large amount of manpower, financial resources and time cost. Based on the above, the blueprint generating method, the blueprint generating device and the electronic equipment of the model provided by the embodiment of the disclosure, and the technology can be applied to equipment such as computers and notebooks.

For the understanding of the present embodiment, first, a detailed description will be given of a blueprint generating method of a model disclosed in the embodiment of the present disclosure, as shown in fig. 1, the method includes the following steps:

step S102, obtaining a target model;

the target model may be various virtual models, such as a building model in a game, a carrier model, a furniture model, a weapon model, etc., and further such as an airship model in a science fiction movie, etc. The object model is usually prefabricated by a worker in three-dimensional graphic image software (such as Blender).

Step S104, extracting the hard edge of the target model, and converting the hard edge of the target model into a wire frame model;

model edges of a general object model include soft edges and hard edges, which differ in whether normal vectors on two faces sharing one edge are continuous, if normal discontinuous changes on two faces sharing one edge, the edge is a hard edge that appears to be a distinct boundary, and if normal continuous changes on two faces sharing one edge, the edge is a soft edge that appears to be a smooth boundary.

In the initial state, in model processing software, according to the included angle of two surfaces sharing one edge, the hard edge and the soft edge of the target model are automatically determined and displayed according to the corresponding display mode. For example, an angle between two faces sharing one edge of greater than 90 degrees is set as a soft edge, and the normal direction on the two faces sharing the soft edge is controlled to continuously change. And setting the hard edge as the two surfaces sharing one edge with an included angle smaller than or equal to 90 degrees, and controlling normal discontinuous change on the two surfaces sharing the hard edge.

The hard edge of the extracted target model may be the hard edge determined in the initial state, or may be the hard edge redetermined according to the need, for example, the included angle of two surfaces sharing one edge is set to be a soft edge by setting the included angle to be greater than 135 degrees. And if the included angle of two surfaces sharing one edge is less than or equal to 135 degrees, the hard edge is set. Wherein the hard edges may also be referred to as structural lines or sharp edges. The soft edges described above may also be referred to as non-structural wires.

After the hard edges of the target model are extracted, the hard edges of the target model are not three-dimensional models, but are only one line segment after being combined, and the line frame of the blueprint is far seen as one line, but is actually composed of a polygonal column (such as a triangular column and the like), so that the hard edges of the target model need to be converted into the polygonal column, and then the line frame model is obtained.

And S106, merging the wire frame model and the target model, setting the transparency and the color value of the wire frame model according to the material balls of the wire frame model, and setting the transparency and the color value of the target model according to the material balls of the target model to obtain a blueprint of the target model.

The target model is an original model for any treatment, and the wire frame model and the target model can be overlapped, so that a blueprint expressed by a pure model can be obtained. The material balls of the wire frame model are pre-generated, and the color, transparency, thickness, color intensity and the like of the wire frame in the wire frame model can be set (edited). The material balls of the target model are also pre-generated, and the color, transparency, color intensity, etc. of the target model can be set (edited), or the color, transparency, color intensity, etc. of the model map of the target model can be set.

Illustratively, a wire frame model as shown in FIG. 2, a target model as shown in FIG. 3, and combining the wire frame model with the target model results in an initial blueprint of the target model as shown in FIG. 4. When the wire frame is set to be opaque and blue by the material ball according to the wire frame model, the target model is set to be transparent and blue by the material ball of the target model, as shown in fig. 5.

The embodiment of the disclosure provides a blueprint generating method of a model, which is used for acquiring a target model; extracting a hard edge of the target model, and converting the hard edge of the target model into a wire frame model; and combining the wire frame model and the target model, setting the transparency and the color value of the wire frame model according to the material balls of the wire frame model, and setting the transparency and the color value of the target model according to the material balls of the target model to obtain a blueprint of the target model. In the method, the hard edge of the target model is extracted, and is converted into the wire frame model, so that the precision of the wire frame is improved, and the blueprints are prevented from being sawteeth; no mapping is required to be made, so that the memory occupation is reduced; and combining the target model with the wire frame model, and setting transparency and color values of the target model and the wire frame model through the material balls, so that the labor, financial and time cost is reduced.

The target model comprises a plurality of model edges, wherein the model edges with the first marks are hard edges, and the model edges without the first marks are soft edges;

the step of extracting the hard edge of the target model and converting the hard edge of the target model into a wire frame model is one possible implementation mode:

step 1, deleting a first mark in a target model;

in actual implementation, the model line of the target model may be set in an editable state in model processing software, for example, after the model line of the target model is set in an editable state by clicking the "smooth coloring" control, the model line (i.e., hard edge and soft edge) of the target model may be controlled to be in an editable state, at this time, the edit control for the opposite edge is clicked to display a pull-down menu, and the sharp edge mark in the "clear sharp edge mark for the vertex" is clicked to correspond to the first mark, and at this time, the first mark in the target model is deleted.

The purpose of the above steps is to determine all model edges in the object model as soft edges, which are displayed in the form of soft edges, in order to facilitate the program to re-determine the hard edges (sharp edges) of the object model as required. That is, the turning edge of the model, the calculated turning edge can be used as the line frame of the blueprint.

Step 2, determining a target hard edge and a target soft edge of a target model from a plurality of model edges based on a preset rule, and adding a first mark on the target hard edge;

the preset rules generally refer to determining the angles of the hard edge and the soft edge, and setting different angles can determine different hard edges and soft edges. Specifically, a first model side formed by adjacent model surfaces with included angles smaller than a first angle is determined from a plurality of model sides, and the first model side is determined as a target hard side; and determining a second model edge formed by adjacent model surfaces with included angles larger than or equal to the first angle, and determining the second model edge as a target soft edge.

For example, the editing state before exiting in the model processing software is firstly exited, then the automatic smoothing parameter is set to be 5 degrees in the model data attribute, and then the custom edge removing normal data is clicked and added. And automatically calculating a target soft edge and a target hard edge of the target model, and determining the edge with the included angle formed by the two die surfaces larger than 135 degrees as the target soft edge and the edge smaller than 135 degrees as the target hard edge according to the first angle calculation.

After the step of determining the target hard edge and the target soft edge of the target model from the plurality of model edges based on the preset rule, the method further comprises: controlling a target hard edge in the target model to be displayed in a first display mode, and controlling a target soft edge in the target model to be displayed in a second display mode; wherein the smoothness of the target soft edge is greater than the smoothness of the target hard edge.

The method is characterized by controlling normal continuous change on two surfaces of a shared target hard edge and controlling normal discontinuous change on two surfaces of a shared target soft edge. Illustratively, as shown in fig. 6, the hard edges of the object with the first mark have sharp corners, have no smooth display effect, and the soft edges of the object without the first mark have no sharp corners, have a smooth display effect.

And 3, extracting the target hard edge with the first mark, and converting the target hard edge into a wire frame model.

Specifically, the target hard edge with the first mark can be directly screened out, for example, the editing state of the model edge of the target model is entered again, and the target hard edge is selected to copy out the target hard edge. Or deleting the molding surfaces, the target soft edges and the like except the target hard edges in the target model to finally obtain the target hard edges with the first marks, and converting the target hard edges into the wire frame model after obtaining the target hard edges.

In the mode, the soft edge and the hard edge of the target model are redetermined according to the preset rule, so that the saw teeth of the blueprint are further reduced, and the blueprint effect of the model is further improved.

In the step 3, the step of extracting the target hard edge with the first mark and converting the target hard edge into the wire frame model is one possible implementation manner:

step 31, deleting the die surface and the target soft edge in the target model to obtain a target hard edge with a first mark; the target hard edge is formed by connecting a plurality of model line segments;

for example, in the editing state of the target model, the target soft edge is selected, the deletion is clicked, the displayed "limited fusion" control is clicked, and then the "limited fusion" control is clicked, so that the target soft edge can be deleted, and a model without triangle lines can be obtained. Then selecting the model surface of the target model, clicking to delete the model surface, displaying the control of 'only surface', clicking the control of 'only surface', deleting the model surface in the target model, and obtaining the target hard edge with the first mark.

Step 32, disconnecting a plurality of model line segments connected in the target hard edge to obtain a plurality of model line segments which are not connected with each other;

in the editing state, the lines are selected completely, and then the V key is pressed to disconnect all the lines. Since in the previous step, after deleting the mold surface, the structural line (i.e. the above-mentioned target hard edge) remains, but this structural line is not a three-dimensional model, and is a line segment, although the blue-drawing line frame is far seen as a line, it is actually composed of triangular prisms, and it is necessary to convert a plurality of model line segments into a line frame model.

Step 33, converting the plurality of model line segments into a wire frame model.

The method is characterized in that a triangular prism is sleeved outside according to the position and trend of a model line segment, then a line frame model is formed, the line is cut off for the purpose of simple calculation of a program, errors are not easy to occur, and the method is easier than the method that all column-shaped bodies of a chair are sleeved with shells, the chair is certainly disassembled into one section, then the shells are sleeved, and then assembly is easier. Without disassembly, there is no way to encase the cylinder therein.

One possible implementation is: updating the line segment types of the plurality of model line segments to obtain a plurality of updated model line segments; lofting the updated plurality of model line segments to obtain lofting models of the plurality of model line segments; and converting the lofting model into a grid model to obtain a wire frame model.

Specifically, an equilateral triangle is created; the line segment type of the equilateral triangle is the same as the line segment type of the updated multiple model line segments; generating triangular prisms corresponding to the equilateral triangles based on the equilateral triangles; setting a plurality of model line segments at the center of the triangular prism to obtain a lofting model of the plurality of model line segments; the model line segment in the lofting model is surrounded by the triangular prism.

For example, the editing mode is exited first, and then the line segment type of the model line segment is converted to the curve type. Only by converting the line type of the model line segment into the curve type, the triangular prism model shell can be arranged at the periphery of the model line segment. An equilateral triangle is then created, the line segment type of which is also of the curve type. In practice, the triangle is a cross section of a triangular prism, the cross section is elongated along the trend of the model line segment to become the triangular prism, and a plurality of model line segments are arranged at the center of the triangular prism to obtain a lofting model of the plurality of model line segments. As shown in fig. 7, a model line segment is provided at the center position of the triangular prism.

After the step of setting the transparency and color value of the wire frame model according to the material ball of the wire frame model and setting the transparency and color value of the target model according to the material ball of the target model, the method further comprises the steps of: and setting the thickness of the model line segment in the wire frame model according to the material balls of the wire frame model.

Specifically, the size of the triangle created by the method can be controlled, so that the thickness of the triangular prism can be adjusted, and the thickness of the model line segment in the wire frame model can be adjusted.

Further, as shown in fig. 8, the blueprint of the final target model obtained in the above manner has a great improvement in the display effect, and the blueprint manufactured in the prior art has more saw teeth. By contrast, the method has the advantages that the precision is improved or the anti-aliasing is improved obviously, the resource size occupies only one ninth of the prior resource size, the manufacturing process is simple, and the effect and the efficiency are improved obviously.
