specifically, each transparent channel has identification information, the coordinates of a target area where the transparent channels need to be superimposed are obtained, and the corresponding target grid coordinate range is obtained by querying and matching according to the target area coordinates, so that a target patch model corresponding to the target grid coordinate range is found out, or the identity ID of the target patch model where the transparent channels need to be superimposed is obtained. The position of the target patch model is found out according to the mode, the transparent channel corresponding to the identification information is superposed on the target patch model, and thus the corresponding transparent channels can be superposed on the plurality of patch models according to requirements, and the corresponding to-be-processed area is obtained according to the transparent channels superposed by the plurality of patch models.
S330, acquiring target pixel values corresponding to all pixel points in the region to be processed, wherein the target pixel values comprise transparent pixels and brightness pixels;

In addition, each pixel point in the same region to be processed is respectively rendered according to the operation result of the control pixel coefficient and the pixel data, and the display interface is further rendered in a regional mode, so that the rendering display mode is more flexible and efficient.
In an embodiment of the present invention, as shown in fig. 4, an image rendering control method includes:
s410, acquiring a grid object corresponding to the display interface, and generating a corresponding patch model according to the grid object;
s420, superposing a transparent channel corresponding to the identification information at the patch model, and extracting a region to be processed corresponding to the patch model through the transparent channel;
s430, if the interface image corresponding to the display interface does not comprise transparent pixels, carrying out gray level processing on the interface image;
s440, obtaining pixel data of a target pixel value corresponding to each pixel point according to the color channel value of each pixel in the interface image after the gray processing;
s450, acquiring target pixel values corresponding to all pixel points in the region to be processed, wherein the target pixel values comprise transparent pixels and brightness pixels;
s460, performing product operation on the control pixel coefficient and the transparent pixel and/or the brightness pixel to obtain a pixel adjusting parameter;
s470, adjusting the pixel state of the region to be processed according to the pixel adjusting parameter, so as to complete the switching display of the pixel state of the display interface.
Specifically, when only the transparent pixels of each pixel point in the region to be processed are obtained through the above embodiment, if the transparent control pixel coefficient and the brightness control pixel coefficient are obtained at this time, only the transparent pixels of each pixel point in the region to be processed are obtained, and therefore, only the product operation is performed on the transparent pixels corresponding to each pixel point and the transparent control pixel coefficient, so as to adjust the transparency of each pixel point in the region to be processed.
Similarly, when only the brightness pixel of each pixel point in the region to be processed is obtained through the above embodiment, if the transparent control pixel coefficient and the brightness control pixel coefficient are obtained at this time, only the product operation is performed on the brightness pixel corresponding to each pixel point and the brightness control pixel coefficient, so as to adjust the brightness (also referred to as brightness) of each pixel point in the region to be processed.
In addition, when the transparent pixel and the brightness pixel of each pixel point in the region to be processed are obtained through the embodiment, if only the transparent control pixel coefficient is obtained, only the product operation is performed on the transparent pixel corresponding to each pixel point and the transparent control pixel coefficient, so that the transparency of each pixel point in the region to be processed is adjusted. Similarly, only the brightness of each pixel point in the region to be processed is adjusted when the brightness control pixel coefficient is obtained.
Illustratively, under the condition that the transparent pixels of a plurality of pixel points are input simultaneously, the product calculation is carried out on the transparent pixels of the plurality of pixel points and the obtained transparent control pixel coefficients respectively, so that the partially transparent surface can be avoided, the original transparency information is covered when transparency readjustment is carried out, and therefore transparency adjustment of different areas is carried out according to requirements.
Referring to fig. 5, an original image (i.e., a two-dimensional image of an interface image of a display interface according to the present invention) is input, and the original image includes transparent pixels and color pixels, i.e., RGB pixels. Extracting transparent pixels of an original image, superimposing a transparent channel on the original image, removing unnecessary parts of the original image in combination with the transparent channel, such as the physical representation of the transparent channel shown in fig. 5, removing a black representative to obtain a non-transparent processing area, and retaining a white representative to obtain a to-be-processed area. The transparency adjustment value (i.e. the transparent control pixel coefficient of the invention) is further superposed on the region to be processed, because the transparent channel is already endowed with the part which needs to be displayed (i.e. the region to be processed) and the part which does not need to be displayed (i.e. the non-transparentization processing region) in the original image. Assuming that the transparent pixel corresponding to the petal part of the area to be processed is 0.5, and the transparent pixel corresponding to the pistil part is 1, at this time, the transparency adjustment value is superposed on the pixel point of the non-transparentization processing area, namely, 0 multiplied by any value is generated as an effect of 0, and the area to be processed is influenced by the transparency adjustment value, namely, 0.5 multiplied by 0.5 to obtain 0.25 for the transparent pixel corresponding to the pixel point of the petal part area, and 0.5 multiplied by 0.5 to obtain 0.5 for the transparent pixel 1 corresponding to the pixel point of the pistil part area, so that the originally opaque pistil part becomes semitransparent, the semitransparent petal area becomes more transparent, and the transparent adjustment effect of the rightmost part area in fig. 5 is presented. Based on the superposition idea of the product mode, the transparency of different regions to be displayed can be adjusted by using the product result of the plurality of transparent channels.
In the embodiment, the to-be-processed area is extracted through the transparent channel, and transparency or brightness rendering is respectively performed on each pixel point of the to-be-processed area according to the operation result of the control pixel coefficient and the pixel data, so that the display interface is rendered in a partition mode synchronously, and the rendering display mode is more flexible and efficient.
In an embodiment of the present invention, as shown in fig. 6, an image rendering control method includes:
s510, acquiring a grid object corresponding to the display interface, and generating a corresponding patch model according to the grid object;
s520, superposing a transparent channel corresponding to the identification information on the patch model, and extracting a region to be processed corresponding to the patch model through the transparent channel;
s530, if the interface image corresponding to the display interface does not comprise transparent pixels, carrying out gray processing on the interface image;
s540, according to the color channel value of each pixel in the interface image after the gray processing, obtaining a target pixel value corresponding to each pixel point to obtain the pixel data;
s550, acquiring a target pixel value corresponding to each pixel point in the region to be processed, wherein the target pixel value comprises a transparent pixel and a brightness pixel;
s560, when the display interface slides, the distance value of each pixel point in the area to be processed relative to the preset origin in the preset moving direction is obtained;
s570, acquiring a corresponding control pixel coefficient according to each distance value, and performing product operation on the control pixel coefficient of each pixel point and a corresponding transparent pixel and/or brightness pixel to obtain a pixel adjusting parameter;
specifically, when the user slides the display interface, the preset origin is selected in advance according to the requirement and the habit preference, and a plane coordinate system is established. Therefore, a distance value of each pixel point in the region to be processed in the preset moving direction relative to the preset original point is obtained, and a preset control coefficient change table is set, wherein the preset control coefficient change table comprises a corresponding relation between the distance value and the transparent control pixel coefficient, and the distance value and the brightness control pixel coefficient. Therefore, the corresponding control pixel coefficient can be obtained according to each distance value, and the control pixel coefficient of each pixel point and the corresponding transparent pixel and/or brightness pixel are subjected to product operation.
Of course, a transparency change curve (or a brightness change curve) may be set in advance, and the transparency change curve (or the brightness change curve) may be a curve which is nonlinear and monotonically increases (or monotonically decreases) with a distance value according to the transparency control pixel coefficient (or the brightness control pixel coefficient). Furthermore, the transparency change curve (or brightness change curve) may also be a curve that is non-linear and that increases (or decreases) with distance value according to the transparency control pixel coefficient (or brightness control pixel coefficient) according to the demand. In short, it is only necessary to conform to the effect that the lower the transparency degree of the pixel point moving toward the preset origin, the higher the lightness degree.
S580 adjusts the pixel state of the region to be processed according to the pixel adjustment parameter, so as to complete the switching display of the pixel state of the display interface.
Specifically, with the popularization of Virtual Reality (VR is abbreviated as VR, and hereinafter referred to as VR), VR application interaction scenes are more and more, so that development and innovation of a Human-machine interface (HMI) are inevitably needed in the VR using process, and various more easily understood graphic interaction schemes are developed according to needs. In the three-dimensional space in the virtual reality scene, various types of menus and interfaces are displayed to become basic functions which each virtual reality application program must have. The virtual menu performs various dynamic effect operations, such as hiding/displaying, transition from opaque to completely transparent, and application of effects such as position movement and color change in many scenes.
In the process of displaying the VR menu, the following technical effects are expected to be realized: the semi-transparency of some areas of the menu in the three-dimensional space is high, and the semi-transparency of some areas is low. Referring to fig. 7, which illustrates a dynamic effect when the VR menu interface is switched, on both sides of a main picture or a logo, a user is prompted to slide left or right to fully display a partially visible object by hiding a part of the object.
In the VR menu switching process, if the area of the left interface body (a3) that has been in the semi-transparent state moves from left to right to approach the preset origin, the middle interface body (a2) moves from left to right to move away from the preset origin, and at this time, the area of the semi-transparent state of the left interface body (a3) gradually becomes the opaque area, and the area of the non-transparent state of the middle interface body (a2) gradually becomes the transparent area.
If the region of the interface body (a1) on the right side, which has already assumed a translucent state, moves in the direction from right to left toward the proximity of the preset origin, the middle interface body (a2) moves in the direction from right to left toward the proximity of the preset origin, at which time the region of the interface body (a1) on the right side in a translucent state gradually becomes an opaque region, and the region of the interface body (a2) in the middle in a non-transparent state gradually becomes a transparent region.
On the contrary, if the region of the left interface body (a3) that has assumed the translucent state moves in the direction from right to left toward a direction away from the preset origin, the region of the left interface body (a3) that has assumed the translucent state gradually becomes a highly transparent region or even a fully transparent region.
