For purposes of making the objects, technical solutions, and advantages of the present disclosure more apparent, the principle and spirit of the present disclosure will be described below with reference to several exemplary embodiments. It should be understood that these embodiments are presented merely to enable one skilled in the art to better understand and practice the present disclosure and are not intended to limit the scope of the present disclosure in any way. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

In this document, it should be understood that any number of elements in the drawings is for illustration and not limitation, and that any naming is used only for distinction and not for any limitation.

The principles and spirit of the present disclosure are explained in detail below with reference to several representative embodiments thereof.

Referring to fig. 1, the crack effect refers to a downward depth at a crack where a target object is broken is simulated in visual effect, and a crack is broken downward in visual effect as if the surface of the target object were seen by a user.

However, the cracking effect in the related art generally requires changing the shape of the target object itself, and there are problems of high cost and poor versatility.

Specifically, the schemes for realizing the crack effect in the related art are as follows: a scheme for changing the material of the target object and a scheme for constructing a crack model.

The scheme for changing the material of the target object, specifically, fusing the map of the crack effect in the shader of the target object is characterized in that the crack effect and the target object are fused naturally.

However, the crack effect is presented as a kind of skill, preferably as a separate effect. Specifically, the cracking effect needs to adapt to different target objects, if the corresponding material needs to be changed for each target object, the cracking effect is quite heavy, and the universality of the material of the target object in the existing scene is not reasonable.

The method for constructing the crack model comprises the steps of constructing a scheme of the crack model, specifically, using the crack model to 'dig out' a target object model by adopting a template test or a depth test method, and finally, selecting a rendering crack model at the crack of the target object as a display effect, wherein the target object model is still rendered at other positions. The scheme is characterized in that the visual effect is relatively real.

However, the scheme of constructing the fracture model requires modifying the values of the template buffer or the order of the rendering queues; the scheme for constructing the crack model has poor universality, and if the shape and the size of the crack effect need to be changed, only the crack model can be reconstructed; the scheme for constructing the crack model can only act on the surface of a flat target object, is not suitable for the surface of the target object with high and low fluctuation, and is limited in applicable scene. In addition, the special effects engineer is not familiar with the templates and depth testing of the engine, and more technical support is required when using the special effects engineer.

In order to solve the above problems, the present disclosure provides a display scheme of a crack effect, specifically including: determining a mask map, a height map and a color gradient map corresponding to the crack effect; synthesizing the mask map, the height map and the color gradient map to obtain a crack map corresponding to the crack effect; and displaying the crack effect at a target position based on the crack map. According to the method and the device, the display of the crack effect can be realized without changing the shape of the target object, the cost is low, and the universality is good.

The server 120 may also send a display of the target crack effect to the client, which presents the display of the target crack effect to the user. Wherein the terminal device may be the aforementioned local terminal device 110.

It should be noted that the above application scenario is only shown for the convenience of understanding the spirit and principles of the present disclosure, and the embodiments of the present disclosure are not limited in any way in this respect. Rather, embodiments of the present disclosure may be applied to any scenario where applicable.

Referring to fig. 3, a flow chart of a method for displaying a crack effect according to an embodiment of the disclosure is shown.

The display method of the crack effect comprises the following steps:

step S210, determining a mask diagram, a height diagram and a color gradient diagram corresponding to the crack effect.

In practice, referring to fig. 4, a mask is used to control the shape of the target fracture.

Referring to fig. 5, a height map for controlling a depth effect of a target crack, wherein white represents a depth deviation completely without deviation, and black represents a depth deviation; it can be realized that the target crack conforms to the depth change from deep to shallow from inside to outside, and the deepest part is the middle part.

Referring to fig. 6, a color gradation diagram for controlling a color gradation effect of a target crack, wherein the innermost is white, which means the brightest color, and the lighter the outermost color, the brightest effect of exposing magma at the center of the target crack.

And S220, synthesizing the mask map, the height map and the color gradient map to obtain a crack map corresponding to the crack effect.

And in the implementation, storing the mask map, the height map and the color gradient map into R, G and B channels respectively to synthesize the target crack map.

In this embodiment, the synthesizing the mask map, the height map, and the color gradient map to obtain the crack map corresponding to the crack effect includes:

and shifting the vertex of the crack map based on the height map, the shifting step number and the shifting amplitude to obtain the depth effect of the crack map.

In a specific implementation, when the position information of the crack map vertex is represented by UV coordinates, a formula for performing offset processing on the crack map vertex at the target position based on the altitude map, the preset offset step number and the preset offset amplitude is represented as follows:

UV’＝UV+f(S，A，H)；

wherein, UV' represents UV coordinates after the crack map vertex is deviated, UV represents UV coordinates before the crack map vertex is deviated, f represents a deviation function, S represents a preset deviation step number (Steps), a represents a preset deviation Amplitude (Amplitude), and H represents a height map.

As a specific example, the preset offset step number may be 5 and the preset offset amplitude may be 10 to 15.

In the above embodiment, after the offset processing is performed on the crack map vertex of the target position, the depth sensation can be simulated at all angles, and the method is a visual spoofing effect, and the original shape of the target model at the position where the crack effect is generated is not required to be changed.

In this embodiment, at least one of the mask map, the height map, and the color gradient map corresponding to the target crack effect is replaced, so that different target crack maps can be obtained.

When the method is implemented, the mask diagram is replaced, and the shape of the target crack can be changed;

the color gradient effect of the target crack can be changed by replacing the color gradient map.

In the above embodiments, the content of the target crack map is described, in some embodiments, the size of the target crack map may be fixedly preset, in other embodiments, the size of the target crack map may be dynamically adjusted, and in the following, the dynamically adjusted size of the target crack map will be described.

In this embodiment, the method for determining the target fracture map includes:

determining a preset crack mapping;

and processing the preset crack mapping based on the size information of the target crack effect to obtain the target crack mapping.

In a specific implementation, the processing the preset crack map based on the size information of the target crack effect to obtain the target crack map includes:

and carrying out stretching treatment and/or shrinkage treatment on the preset crack mapping based on the size information of the target crack effect to obtain the target crack mapping.

As a specific example, according to the size information of the target crack effect, the rolling parameter of the preset crack map is adjusted to implement stretching treatment and/or shrinkage treatment on the preset crack map.

Wherein, the role of Tilling is to determine the size of a picture;

if the values of tilling. X and tilling. Y are both 0.5, then the size of the picture is 0.5 x 0.5;

if the values of tilling. X and tilling. Y are both 1, then the size of the picture is 1*1;

if the values of tilling. X and tilling. Y are both 2, then the size of the picture is 2 x 2.

In the above embodiment, the preset shape of the crack map is stretched or shrunk by changing the Tilling, however, this may cause deformation of the preset shape of the crack map, so, in order to avoid deformation of the preset shape of the crack map, the present disclosure also provides a determination method for stitching to obtain the target crack map, details of which are described in the following embodiments.

And step S230, displaying the crack effect at the target position based on the crack mapping.

In this embodiment, displaying the crack effect at the target location based on the crack map includes:

determining size information of the crack effect;

processing the crack map based on the size information of the crack effect to obtain a target crack map;

and displaying the crack effect at the target position based on the target crack map.

In this embodiment, the processing the crack map based on the size information of the crack effect to obtain a target crack map includes:

determining size information of the first end crack map and the second end crack map;

obtaining a target number of the middle crack map based on the crack effect, the first end crack map and the second end crack map;

and splicing the first end crack mapping, the second end crack mapping and the target number of the middle crack mapping to obtain the target crack mapping.

Referring to fig. 7, as a specific example, a preset crack map 301 is divided into a first end crack map 302, a middle crack map 303, and a second end crack map 304.

In this embodiment, the dividing the crack map into a first end crack map, a second end crack map, and an intermediate crack map includes:

determining a mask map for division;

the split map is divided into the first end split map, the second end split map, and the intermediate split map based on the division mask map moving on the split map.

In this embodiment, displaying the crack effect at the target location based on the target crack map includes:

and moving the positions of the division masks according to a specified sequence, and controlling the first end crack mapping, the second end crack mapping and the middle crack mapping to be displayed at the target positions.

In this embodiment, the method further includes, after the first end crack map, the second end crack map, and the intermediate crack map are displayed in the target position in the specified order, controlling the first end crack map, the second end crack map, and the intermediate crack map to be displayed in the target position, where the first end crack map, the second end crack map, and the intermediate crack map are displayed in the specified order:

recording the first end crack map, the second end crack map, the intermediate crack map and display positions thereof, and controlling deletion of the display positions of the first end crack map, the second end crack map and the intermediate crack map in response to a deletion operation of the record so as to cancel the display.

The specific implementation method comprises the following steps: the growth direction and length of the target fracture effect can be controlled. The shape of the crack can be divided into a head part, a tail part and a middle part, and then the head part, the tail part and the middle part can be spliced according to the length each time, so that the shape of the crack can be ensured, and the shapes of the head part, the tail part and the middle part can be cut out by adjusting parameters in materials.

A complete slit can be considered to be made up of three parts, a head, a middle, and a tail. The length of the crack is not changed, and the crack has a head part and a tail part, and the effect of prolonging the length of the crack is achieved by superposing a plurality of middle sections. The head, the middle and the tail all share the same parent material and the map, so that the advantage is that no matter how many sections of heads exist, the middle and the tail can be combined into one batch for rendering, and the performance is improved.

The range to be displayed is controlled by moving the black-and-white mask in the Y-axis direction of the slit, so that the cutting effect is achieved. For example, if a head is to be cut, one such black and white mask is required, and then the middle and tail mask is moved down in sequence by the white portions of the mask. Only one parameter needs to be added to the parent material to control the extent of the mask, and the UV coordinates themselves can be used as a mask, with the advantage that they do not take up space nor require additional mapping and are not changed by resolution changes.

Specifically, the black-and-white mask is calculated by a smooth gradual change map:

referring to fig. 8, the smooth gradation map refers to a vertical-direction black-to-white gradation map in which the Y-coordinate of the UV-coordinate that has not been modified is long by default, and the Y-axis (G-channel) in the XY-axis (RG-channel) of the UV-coordinate is a smooth gradation map from 0 to 1 in value. What is needed here is a desired mask by some transformation of the UV coordinates, i.e. an output mask as shown in fig. 9 (black and white mask as described earlier), which is derived from the UV gradient map of the smooth gradient map. The output mask is a hard-sided, black up and down, and white in the middle. The hard edges are cut by subtracting to control the starting point of the fade and then removing the fractional part using the floor function. The method is specifically calculated by the following formula:

Out＝floor(uv.y-MoveTop)*floor((1-uv.y)-MoveDown)；

Out is the final output mask map, and the range of this white bar is controlled by changing the values of the two parameters MoveUp and MoveDown.

Where this fade starts, it is initially defaulted to 0 uppermost and then transitions to 1 lowermost by subtracting a value from the Y coordinate of uv. The above part can now be controlled by subtraction, all first 0, from a certain point on the transition from 0 to 1. This is to control the white area of the mask.

The mask pattern is multiplied by the original crack map to cut out the desired part, for example, the lower pattern can cut out the tail of the crack.

The program is transmitted into the length data of the nearest collision body, a plurality of sections of the middle section can be calculated according to the length data, the tail part is generated first, the middle section of a plurality of sections is generated again, and finally the head part is generated, so that the effect of crack growth is achieved. And the array is written in turn during regeneration, and the array can be traversed to clear the cracks when the cracks disappear.

Firstly, each part is very abrupt if appearing instantly and simultaneously, the reasonable effect is that the part grows gradually from the tail to the head, the growth effect is very complex if the part is made by a model, and model animation needs to be added, but the realization is realized based on mapping at present, so that the method is relatively simple. This is also one of the benefits of using mapping.

Firstly, the problem of crack generation with different lengths is not considered, and firstly, a basic method is described that the crack which comprises a tail part, a middle part and a head part is generated.

Firstly, three parts can be cut by the cutting method, and the method can change the display range of the crack by moving the mask, then the effect of growing animation can be simulated by slowly moving the mask range, when the mask range is expanded from the bottom to the top in a set time, the display range of the crack is gradually expanded from the tail to the head, and then the effect of growing the crack from the tail to the head can be simulated.

Mask range of movement range = mathf. Lerp (start point of movement, end point of movement, time of movement)

Based on this principle, the number of intermediate sections to be added can now be calculated based on the length to which the crack that has propagated in on the side of the program needs to be grown, considering that cracks of different lengths are generated first.

Middle number= (total length- (head length + tail length))/middle length

It is just as basic crack generation, but is generated several times more when generating the middle section. The tail, middle and head blocks are stored as a prefab (module) and then generated beginning at the designated world location to generate a head module.

Then the MoveDown needs to be moved to let the head module slowly show up for a prescribed time opnefactor head.

The world location point generated by the next segment is then updated forward,

it is also noted that since all the generated modules need to be destroyed uniformly when the crack effect disappears, the modules are sequentially questioned into an array when being generated, and finally the list is destroyed.

The principle of generating the middle section and the tail section is consistent with that of the head module, namely the middle section module needs to traverse an array for multiple times.

The appearance direction of the cracks is based on the movement of the mapping mask, the designated sequence is that the first end crack mapping is displayed firstly, then the middle crack mapping is displayed, and finally the mask is required to be moved up and down when the second end crack mapping is displayed; the specified sequence is to display the middle crack mapping first and then to display the mask spreading from the center when the first end crack mapping and the second end crack mapping are displayed simultaneously.

Referring to fig. 10, the effect of the generated target fracture is illustrated.

and controlling the projection of the crack mapping to the target position so as to display the crack effect.

As a specific example, assuming that the specified model is a weapon model such as a knife, a sword, an axe, etc., the target model is a ground model, and the specified interaction behavior is actions such as splitting, chopping, sliding, etc., the specified interaction behavior of the target model through the specified model is specifically: the weapon models such as knives, swords and axes are used for carrying out actions such as splitting, chopping, sliding and the like on the ground model.

judging whether the edge of the appointed model is intersected with the plane to which the surface of the target model belongs;
