Detailed Description

For ease of understanding, a description of some of the concepts related to the embodiments of the present application are given by way of example for reference.

The following is shown:

screen space refraction: a technology commonly used in computer graphics is used for simulating refraction effects of objects such as glass, water surface and the like in real time rendering, increasing the reality and details of rendering, and has wide application in the fields of games, movies and the like.

In order to make the present application solution better understood by those skilled in the art, the following description will be made in detail and with reference to the accompanying drawings in the embodiments of the present application, it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, shall fall within the scope of the present application.

It should be noted that the terms "first," "second," and the like in the description and claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

In one possible implementation, in the field of image processing technology, when rendering a refraction effect, a refraction effect is typically rendered using a screen space refraction effect that is self-contained in the UE.

The inventor has found that the above method still has the problems of refracting the content above the refracting plane, incorrect semitransparent effect of refraction and large consumption after being practiced and studied carefully. As shown in fig. 1, fig. 1 is a schematic diagram of an image rendered by using a refraction effect of a UE, wherein a refraction plane is formed by numerals 1-9, a reference sphere with a fixed position is located behind the refraction plane to provide, as a reference, a refraction intensity of the reference sphere behind the refraction plane, and the target sphere is a sphere with an unfixed position, and can move in front of the refraction plane or move behind the refraction plane or reciprocate in front of and behind the refraction plane through the refraction plane.

It will be appreciated that when the target sphere is in front of the refraction plane, the correct refraction effect should be that no refraction will occur behind the refraction plane, but as can be seen from fig. 1 (a), when the refraction effect carried by the UE is used for rendering, incorrect shadows, i.e. incorrect refraction effects, still occur when the target sphere is in front of the refraction plane. Furthermore, it will be appreciated that when the target sphere is located behind the refractive plane, the correct refractive effect should be that the target sphere is at a different distance from the refractive plane, as well as the refractive strength. However, as can be seen from fig. 1 (B) and (c), the refractive intensity a of the target sphere behind the refractive plane and closer to the refractive plane is the same refractive intensity as the refractive intensity B of the target sphere behind the refractive plane and farther from the refractive plane, that is, when the UE self-contained refractive effect is used for rendering, the distances between the target sphere behind the refractive plane and the refractive plane in (B) and (c) are different, but the degree of distortion of the target sphere in (B) and (c) is the same, so that the refractive effect is incorrect.

Based on this, the application game of the embodiment of the present application may be an image processing field in a game, and a mapping processing method is provided, where a distortion value is determined based on a preset mapping, where the preset mapping is used to simulate a distortion manner of refraction processing, and the distortion value is used to represent a distortion intensity of any pixel of the preset mapping in a screen space; performing offset processing on a first texture coordinate of the initial mapping based on the distortion value to obtain a distortion mapping, wherein the initial mapping is the mapping to be mapped onto the target object; determining a target texture coordinate based on the first texture coordinate, a second texture coordinate of the distortion map and distance information, wherein the distance information comprises a first distance and a second distance, the first distance is a distance between a first position of a pixel point of the initial map on the target object and a preset refraction plane, and the second distance is a distance between a second position of the pixel point of the distortion map on the target object and the preset refraction plane; and performing texture sampling on the initial mapping based on the target texture coordinates to obtain a target mapping, wherein the target mapping is used for simulating a refraction effect obtained after refraction processing is performed on the target object, and the distortion strength of the target mapping is changed based on a third distance between the target object and a preset refraction plane. The purpose that the refractive intensity is changed according to the distance between an object and a refractive plane, and the refractive intensity is higher when the distance is farther is achieved, so that the technical effects of correctly simulating the semitransparent refractive effect by adopting lower consumption and increasing the rendering sense of reality and details are achieved, and the technical problem that the semitransparent refractive effect is incorrect due to the fact that the refractive effect is simulated by adopting the screen space refraction, light tracking and other technologies in the related technology is solved.

According to one embodiment of the present application, there is provided an embodiment of a mapping processing method, it should be noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions, and that, although a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in an order other than that illustrated herein.

In a possible implementation manner, an embodiment of the present application provides a mapping processing method, and fig. 3 is a flowchart of the mapping processing method according to one embodiment of the present application, as shown in fig. 3, and the method includes the following steps:

in step S30, a distortion value is determined based on the preset map.

The preset mapping is used for simulating a distortion mode of refraction processing, and the distortion value is used for representing the distortion intensity of any pixel of the preset mapping in a screen space.

The preset mapping is a custom mapping, and is used for determining a distortion standard of the mapping to be processed, namely, a distortion mode for simulating refraction processing, so that the mapping to be processed is distorted in a distortion mode represented by the preset mapping.

The preset map may be a normal map, and since the normal map uses only R channels and G channels, which respectively represent a lateral concave-convex manner and a longitudinal concave-convex manner of the object surface, a distortion criterion of the map to be processed can be defined.

The twist value is referred to as the twist strength and can be understood as the refractive strength. It will be appreciated that each pixel in the preset map corresponds to a warp value that indicates in which direction the pixel is warped, and thus the warp value includes the corresponding warp strength in screen space for each pixel in the preset map.

The way of warping, i.e. the way of refraction, of the map to be processed can be determined by determining the warping value.

In step S32, the first texture coordinates of the initial map are shifted based on the warp value, so as to obtain a warp map.

Wherein the initial map is a map to be mapped onto the target object.

The initial mapping is mapping to be mapped to a target object, and the target object can be understood as an object to be subjected to refraction treatment, namely an object needing to be subjected to refraction through a refraction plane.

The first texture coordinates include texture coordinates for each pixel in the initial map.

And performing offset processing on the first texture coordinates of the corresponding pixels in the initial mapping based on the distortion values, so that the initial mapping can be distorted according to a distortion mode of a preset mapping, and a distorted mapping is obtained.

Step S34, determining the target texture coordinates based on the first texture coordinates, the second texture coordinates of the warp map, and the distance information.

The distance information comprises a first distance and a second distance, wherein the first distance is the distance between a first position of a pixel point of the initial mapping on the target object and a preset refraction plane, and the second distance is the distance between a second position of the pixel point of the distortion mapping on the target object and the preset refraction plane.

The first position may be understood as a position of a pixel of an image obtained after the initial map is mapped to the target object, and the first distance is a distance between the position of the pixel of the image obtained after the initial map is mapped to the target object and a preset refraction plane. Correspondingly, the second position may be understood as a position of a pixel of an image obtained by mapping the distortion map to the target object, and the second distance is a distance between the position of the pixel of the image obtained by mapping the distortion map to the target object and a preset refraction plane.

It will be appreciated that the correct refractive effect is that the refractive intensity varies based on the distance of the object from the refractive plane, the closer the object is to the refractive plane, the smaller the refractive intensity, and conversely the farther the object is from the refractive plane, the greater the refractive intensity. For example, in a terrorist sheet, a ghost runs from a distance to ground glass (refractive plane) and sticks to ground glass, and during this process, the form of the ghost viewed by an observer from the other side of ground glass changes from "very blurred (i.e. high refractive intensity)" to "clear (i.e. low refractive intensity)". For another example, when the window glass is full of rain, a person or car at a distance from the vehicle, a horse or person (i.e., an object far from the refractive plane) may become unclear (i.e., large in refractive intensity) in the vehicle, but the wiper blade (i.e., an object near the refractive plane) is still clearly visible (i.e., small in refractive intensity). Therefore, when the refraction effect is rendered, the relation between the distance between the object and the refraction plane and the refraction intensity needs to be considered, so that the correct refraction effect of the object can be rendered.

In consideration of the relationship between the distance between the target object and the preset refraction plane and the refraction intensity, in the embodiment of the present application, the target texture coordinate is determined based on the first texture coordinate of the initial map, the second texture coordinate of the distortion map, the first distance between the first position of the pixel point of the initial map on the target object and the preset refraction plane, and the second distance between the second position of the pixel point of the distortion map on the target object and the preset refraction plane, so that the obtained target texture coordinate is determined based on the distance between the target object and the preset refraction plane, and further a correct semitransparent refraction effect is achieved.

Step S36, performing texture sampling on the initial mapping based on the target texture coordinates to obtain a target mapping.

The target map is used for simulating a refraction effect obtained after refraction treatment is carried out on the target object, and the distortion strength of the target map is changed based on a third distance between the target object and a preset refraction plane.

The target mapping can be understood as a mapping obtained by simulating the refraction effect of the target object according to the mapping processing method provided by the embodiment of the present application, and because the mapping processing method provided by the embodiment of the present application changes the refraction intensity based on the distance change between the target object and the preset refraction plane, the initial mapping is texture-sampled based on the target texture coordinates, and the obtained target mapping can achieve the technical effects that the closer the distance between the target object and the preset refraction plane is, the smaller the refraction intensity is, the further the distance between the target object and the preset refraction plane is, and the larger the refraction intensity is.

As shown in fig. 4, fig. 4 is a schematic image rendered by the method according to one embodiment of the present application, and the refractive intensities of the refraction plane, the target sphere, and the reference sphere in fig. 1 behind the refraction plane are consistent. It will be appreciated that the image shown in fig. 4 is a rendered representation of the target map mapped onto the target object. The refraction effect when the target sphere is in front of the refraction plane is simulated by the graph (a) in fig. 4, and it can be seen that the incorrect shade of refraction does not appear in the graph (a), i.e. the refraction effect is correct. In fig. 4, the simulation of the graph (b) and the graph (C) is the corresponding refraction effect when the target sphere is located at different distances behind the refraction plane, and it can be seen that the refraction intensity C of the target sphere when the target sphere is behind the refraction plane and is close to the refraction plane is different from the refraction intensity D of the target sphere when the target sphere is behind the refraction plane and is far from the refraction plane, and it can be seen that the refraction intensity of the refraction intensity C is smaller than the refraction intensity of the refraction intensity D, that is, the technical effects that the closer the object is to the refraction plane, the smaller the refraction intensity is, the further the object is from the refraction plane, and the larger the refraction intensity is are achieved.

Through the steps, the distortion value is determined based on the preset map, wherein the preset map is used for simulating the distortion mode of refraction processing, and the distortion value is used for representing the distortion intensity of any pixel of the preset map in the screen space; performing offset processing on a first texture coordinate of the initial mapping based on the distortion value to obtain a distortion mapping, wherein the initial mapping is the mapping to be mapped onto the target object; determining a target texture coordinate based on the first texture coordinate, a second texture coordinate of the distortion map and distance information, wherein the distance information comprises a first distance and a second distance, the first distance is a distance between a first position of a pixel point of the initial map on the target object and a preset refraction plane, and the second distance is a distance between a second position of the pixel point of the distortion map on the target object and the preset refraction plane; and performing texture sampling on the initial mapping based on the target texture coordinates to obtain a target mapping, wherein the target mapping is used for simulating a refraction effect obtained after refraction processing is performed on the target object, and the distortion strength of the target mapping is changed based on a third distance between the target object and a preset refraction plane. The purpose that the refractive intensity is changed according to the distance between an object and a refractive plane, and the refractive intensity is higher when the distance is farther is achieved, so that the technical effects of correctly simulating the semitransparent refractive effect by adopting lower consumption and increasing the rendering sense of reality and details are achieved, and the technical problem that the semitransparent refractive effect is incorrect due to the fact that the refractive effect is simulated by adopting the screen space refraction, light tracking and other technologies in the related technology is solved.

In a possible implementation manner, in step S30, determining the distortion value based on the preset map may include the following steps:

step S300, obtaining a third texture coordinate of a preset map;

step S301, scaling the third texture coordinates based on a preset scaling ratio to obtain a scaled map;

in step S302, a warp value is determined based on the first channel value of the scaled map, the second channel value of the scaled map, and the predetermined warp ratio.

The preset scaling is a scaling value for texture coordinates, which may be determined based on actual art requirements, and is not limited herein. The first channel value may be an R channel value and the second channel value may be a G channel value. The preset distortion ratio is used to adjust the distortion ratio of the screen space, and may be determined based on actual art requirements, without limitation.

When determining the corresponding distortion value of each pixel based on the preset map, first obtaining the third texture coordinate of the preset map, multiplying the preset scaling ratio determined according to the art requirement by the third texture coordinate, and scaling the preset map to obtain the scaled map. And then obtaining an R channel value and a G channel value of the scaling map, and multiplying the R channel value, the G channel value and a preset distortion proportion, so as to determine a distortion value corresponding to each pixel in the preset map.

In a possible implementation manner, in step S32, performing offset processing on the first texture coordinates of the initial map based on the warp value, to obtain the warp map may include the following steps: and adding the distortion value and the corresponding first texture coordinate to obtain the distortion map.

When the first texture coordinates of the initial map are subjected to offset processing based on the distortion values, the first texture coordinates are subjected to offset processing by adding the distortion values to the corresponding first texture coordinates, and the distortion map is obtained.

In a possible implementation manner, in step S34, determining the target texture coordinate based on the first texture coordinate, the second texture coordinate of the warp map, and the distance information may include performing the steps of:

step S340, determining a target weight value based on the first distance and the second distance.

The target weight value is used for representing weight values corresponding to different distances between the target object and a preset refraction plane.

The first distance is the distance between the first position of the pixel point of the initial mapping on the target object and the preset refraction plane, the second distance is the distance between the second position of the pixel point of the distortion mapping on the target object and the preset refraction plane, and the weight values corresponding to different distances between the object and the refraction plane can be determined based on the first distance and the second distance, so that the refraction intensity corresponding to different distances can be determined based on the target weight values.

Step S341, interpolation processing is performed on the first texture coordinates, the second texture coordinates and the target weight value to obtain target texture coordinates.

And carrying out interpolation processing (such as Lerp processing) on the first texture coordinates of the initial mapping, the second texture coordinates of the distortion mapping and target weight values corresponding to different distances between the target object and the preset refraction plane to obtain a target mapping, so that the refraction intensity can be controlled through the distances. The target map can be smoothly transited between the initial map and the distortion map based on different distances between the target object and the preset refraction plane, so that the closer the target object is to the preset refraction plane, the smaller the refraction intensity is, namely the smaller the distortion degree is, the farther the target object is to the preset refraction plane, the larger the refraction intensity is, namely the larger the distortion degree is, the technical effect is, and the semitransparent refraction effect is accurately simulated.

In a possible implementation manner, in step S340, determining the target weight value based on the first distance and the second distance may include performing the steps of:

step S3400, mapping the first distance to a preset distance range to obtain a first weight value;

step S3401, mapping the second distance to a preset distance range to obtain a second weight value;

And S3402, carrying out fusion processing on the first weight value and the second weight value to obtain a target weight value.

The first weight value is used for representing weight values corresponding to different distances between the first position and a preset refraction plane, and the second weight value is used for representing weight values corresponding to different distances between the second position and the preset refraction plane.

The preset distance range is used for defining a distance range between the pixel point position of the image and a preset refraction plane, namely, the distance range between the pixel point position of the image obtained after mapping the map to the target object and the refraction plane, and the distance range can be determined based on actual art requirements through the distance scaling value representation, and is not limited herein.

It will be appreciated that the technical effect of a smooth transition can be achieved only by ensuring that the distance range between the first position of the pixel point of the initial map on the target object and the preset refraction plane is the same as the distance range between the second position of the pixel point of the warp map on the target object and the preset refraction plane, and therefore the first distance and the second distance need to be mapped (e.g. Remap processed) to the same preset distance range, e.g. to (0,500), so that the technical effect of a smooth transition between the initial map and the warp map based on the difference of distances can be correctly achieved.

When determining the target weight value, it is necessary to determine a first weight value mapping the first distance to a preset distance range and a second weight value mapping the second distance to the preset distance range, and the target weight value is obtained by performing fusion processing (for example, min processing) on the first weight value and the second weight value.

step S342, a third distance between the preset refraction plane and the camera, a fourth distance between the first position and the camera and a fifth distance between the second position and the camera are obtained;

step S343, subtracting the fourth distance from the third distance to obtain a first distance;

in step S344, the fifth distance is subtracted from the third distance to obtain the second distance.

As shown in fig. 5, fig. 5 is a schematic diagram of a positional relationship according to an embodiment of the present application, where the three-dimensional coordinate system as shown in fig. 5 can be established including a camera, a refraction plane, and a position of an object in the three-dimensional coordinate system within a screen, and the camera position can be understood as the screen position. It will be appreciated that in a three-dimensional coordinate system (i.e. looking into the screen from the screen position), the object will move in front of the plane of refraction, or behind the plane of refraction, or back and forth across the plane of refraction in front of and behind the plane of refraction.

Thus, when determining the target texture coordinates, by obtaining a third distance between the preset refraction plane and the camera, a fourth distance between the camera and a first position of a pixel point of the initial map on the target object, and a fifth distance between the camera and a second position of a pixel point of the warp map on the target object, the distances between the first position and the second position and the camera can be regarded as the distances between the object and the camera in fig. 5. Subtracting the third distance from the fourth distance to obtain a first distance between the first position and the preset refraction plane, and subtracting the third distance from the fifth distance to obtain a second distance between the second position and the preset refraction plane.

In a possible implementation manner, in step S342, obtaining the third distance may include the following steps:

step S3420, subtracting the position of the camera from the position of the preset refraction plane to obtain a three-dimensional distance;

in step S3421, a third distance is determined based on the three components of the three-dimensional distance.

When the third distance between the preset refraction plane and the camera is obtained, the position of the camera and the position of the preset refraction plane can be subtracted, so that three-dimensional coordinates (a, b, c) are obtained and used for representing the three-dimensional distance. Three components of the three-dimensional coordinates are based on The formula is calculated so that a third distance between the preset refraction plane and the camera can be determined.

In a possible implementation manner, in step S342, acquiring the fourth distance and the fifth distance may include performing the steps of:

step S3422, determining a fourth distance based on the depth information of the first position;

step S3423, determining a fifth distance based on the depth information of the second position.

The depth information of a position can be understood as numerical information of the Z axis of the position in the three-dimensional coordinate system shown in fig. 5.

When the fourth distance between the first position of the pixel point on the target object and the camera of the initial map and the fifth distance between the second position of the pixel point on the target object and the camera of the distortion map are obtained, the fourth distance between the first position and the camera can be determined according to the depth information of the first position in the three-dimensional coordinate system, and the fifth distance between the second position and the camera can be determined according to the depth information of the second position.
