According to the method, the position of the target patch model is found, the transparent channel corresponding to the identification information is overlapped at the position of the target patch model, so that the corresponding transparent channels can be overlapped at the positions of the patch models according to requirements, and the corresponding area to be processed is obtained according to the transparent channels overlapped by the patch models.
S330, obtaining 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 one 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, overlapping transparent channels corresponding to the identification information at the patch model, and extracting a to-be-processed area corresponding to the patch model through the transparent channels;
s430, if the interface image corresponding to the display interface does not comprise transparent pixels, carrying out gray processing on the interface image;

s470, adjusting the pixel point state of the area to be processed according to the pixel adjusting parameters so as to finish the pixel state switching display of the display interface.
Specifically, when only the transparent pixel of each pixel point in the to-be-processed area 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 transparent pixel of each pixel point in the to-be-processed area is obtained, so that the product operation is performed only on the transparent pixel corresponding to each pixel point and the transparent control pixel coefficient, thereby adjusting the transparency of each pixel point in the to-be-processed area.
Similarly, when only the brightness pixel of each pixel point in the area to be processed is obtained by the above embodiment, if the transparent control pixel coefficient and the brightness control pixel coefficient are obtained at this time, the product operation is performed only 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 area to be processed.
In addition, when the transparent pixel and the brightness pixel of each pixel point in the area to be processed are obtained through the above embodiment, if only the transparent control pixel coefficient is obtained, the product operation is only 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 area to be processed is adjusted.

In an exemplary case where transparent pixels of a plurality of pixel points are input at the same time, product calculation is performed on the transparent pixels of the plurality of pixel points and the acquired transparent control pixel coefficients respectively, so that the surface which is already partially transparent can be avoided, original transparency information is covered when transparency readjustment is performed, and transparency adjustment of different areas is performed according to requirements.
Detailed description referring to fig. 5, an original image (i.e., a two-dimensional image of an interface image of a display interface of the present invention) including transparent pixels and color pixels, i.e., RGB pixels, is input. The transparent pixels of the original image are extracted, the transparent channels are superimposed on the original image, unwanted parts of the original image are removed by combining the transparent channels, and as shown in fig. 5, the transparent channel mapping is the physical representation of the transparent channels, black represents is removed to obtain a non-transparent processing area, and white represents remains to obtain a to-be-processed area. The transparency adjustment value (i.e., the transparency control pixel coefficient of the present invention) is superimposed again on the region to be processed, since the transparent channel has already been assigned to the portion to be displayed (i.e., the region to be processed) and the portion not to be displayed (i.e., the non-transparentized region) in the original image. Assuming that the transparent pixels corresponding to the petals of the area to be treated are 0.5 and the transparent pixels corresponding to the pistil are 1, at this time, the transparency adjustment value is superimposed on the pixels of the non-transparentizing treatment area, that is, an effect that 0 times any value is 0 is generated, and the area to be treated is affected by the transparency adjustment value, that is, 0.25 is obtained by multiplying 0.5 by 0.5 for the transparent pixels corresponding to the pixels of the petals of the area to be treated, 0.5 is obtained by multiplying 0.5 for the transparent pixels 1 corresponding to the pixels of the pistil area, so that the originally opaque pistil part becomes semitransparent, and the semitransparent petal area becomes more transparent, thereby presenting the split area transparency adjustment effect as far as the right side in fig. 5. Based on the superposition thought of the product mode, the transparency of different areas to be displayed can be adjusted by using the product result through the multiple transparent channels.
In this embodiment, the region to be processed is extracted through the transparent channel, and according to the operation result of controlling the pixel coefficient and the pixel data, transparency or brightness rendering is performed on each pixel point of the region to be processed, so that region division and synchronous rendering are implemented on the display interface, and the rendering display mode is more flexible and efficient.
In one 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, overlapping transparent channels corresponding to the identification information at the patch model, and extracting a region to be processed of the corresponding patch model through the transparent channels;
S530, if the interface image corresponding to the display interface does not comprise transparent pixels, carrying out gray processing on the interface image;
S540, obtaining a target pixel value corresponding to each pixel point according to the color channel value of each pixel in the interface image after gray processing to obtain the pixel data;
s550, obtaining 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;
s560, acquiring a distance value of each pixel point at the to-be-processed area relative to a preset origin in a preset moving direction when the display interface slides;
S570 obtains corresponding control pixel coefficients according to each distance value, and performs product operation on the control pixel coefficients of each pixel point and the corresponding transparent pixels and/or brightness pixels to obtain pixel adjustment parameters;
Specifically, when the user slides the display interface, a preset origin is selected in advance according to requirements and habit preferences, and a plane coordinate system is established, and when the display interface slides, the coordinate value of each pixel point on the plane coordinate system changes, so that the distance value of each pixel point relative to the preset origin changes, and the distance value is an absolute value. Therefore, a distance value of each pixel point at the area to be processed relative to a preset origin in a preset moving direction is obtained, a preset control coefficient change table is set, and the preset control coefficient change table comprises a corresponding relation between the distance value and a transparent control pixel coefficient, and the distance value and a brightness control pixel coefficient. Therefore, the corresponding control pixel coefficient can be obtained according to each distance value, and the product operation can be carried out on the control pixel coefficient of each pixel point and the corresponding transparent pixel and/or brightness pixel.
Of course, a transparency change curve (or a brightness change curve) may be preset, and the transparency change curve (or the brightness change curve) may be a curve that is nonlinear and monotonically increases (or monotonically decreases) with the distance value according to the transparency control pixel coefficient (or the brightness control pixel coefficient). In addition, the transparency change curve (or brightness change curve) may also be a curve that is nonlinear and increases (or decreases) with the distance value according to the transparency control pixel coefficient (or brightness control pixel coefficient) according to the demand. In short, the effect of higher brightness level can be satisfied as the transparency level of the pixel point moving toward the vicinity of the preset origin is lower.
S580 adjusts the pixel point state of the area to be processed according to the pixel adjusting parameters to complete the pixel state switching display of the display interface.
Specifically, with the popularization of Virtual Reality (VR), VR application interaction scenarios are more and more, which inevitably requires development and innovation of a human-machine interface (Human Machine Interaction, HMI) in the VR use process, and various graphic interaction schemes which are easier to understand are developed according to the requirements. In the three-dimensional space in the virtual reality scene, various types of menus and interface displays become basic functions which each virtual reality application program must have. The virtual menu performs various dynamic effects such as hiding/displaying, opaque to completely transparent transition, position shifting, color changing and other effects, and the like, are applied in many scenes.
In the VR menu display process, it is desirable to achieve the following technical effects: the menu in three-dimensional space has high translucency in certain regions and low translucency in certain regions. Referring to fig. 7, a dynamic effect during switching of the VR menu interface is illustrated, and a user is prompted to slide left or right to fully display a part of visible objects by means of invisible part of the objects on both sides of the main picture or the logo.
In the VR menu switching process, if the area in the semitransparent state in the left interface body (a 3) moves along the direction from left to right towards the position close to the preset origin, the middle interface body (a 2) moves along the direction from left to right towards the position far away from the preset origin, at this time, the area in the semitransparent state of the left interface body (a 3) gradually becomes an opaque area, and the area in the non-transparent state of the middle interface body (a 2) gradually becomes a transparent area.
When the interface body (a 2) in the middle moves in the right-to-left direction toward the direction away from the preset origin if the area of the interface body (a 1) on the right side has been in the semitransparent state, the area of the interface body (a 1) on the right side gradually becomes an opaque area, and the area of the interface body (a 2) on the middle in the non-transparent state gradually becomes a transparent area.
Conversely, if the area of the interface body (a 3) on the left that has been rendered semi-transparent is moved in the right-to-left direction away from the preset origin, the area of the interface body (a 3) on the left that is semi-transparent gradually becomes a highly transparent area or even a fully transparent area. When the area of the interface body (a 1) on the right side, which has been in a semitransparent state, moves away from the preset origin in the direction from left to right, the area of the interface body (a 1) on the right side gradually becomes a high transparent area or even a full transparent area. The above is only an example of the left and right interface bodies, and the manner of adjusting the upper and lower interface bodies by sliding up and down is not described here in detail.
