As shown in fig. 1, the present application provides a space display method for tiles, the method comprising:
s1, acquiring a pre-established three-dimensional space model;
s2, performing image matting processing on a brick replacement area of the three-dimensional space model to obtain a first image matting image;
s3, rendering the first matting image into a space effect image consistent with the illumination attribute of the preset target image;
s4, code fusion is carried out on the reflection image of the space effect image and all illumination, transparency display is carried out on the obtained fusion image, and a shadow reflection image is generated;
s5, combining and superposing the shadow reflection graph, the space effect image and the three-dimensional space model, and displaying the superposition effect in real time.
In step S1, the pre-establishing of the three-dimensional space model includes:
sending a three-dimensional space display request to a server, wherein the three-dimensional space display request comprises a space scene type;
the server generates a three-dimensional space model according to the space scene type and sends corresponding three-dimensional space model data;
receiving three-dimensional space model data sent by the server; the three-dimensional space model data comprises pixel point information contained in a three-dimensional space and replaceable tile maps matched with the three-dimensional space model.
In step S2, the acquiring the first matte image includes:
setting at least one editable area on the three-dimensional space model as a brick replacement area;
and selecting a color key to perform image matting processing on the brick replacement area of the three-dimensional space model, and acquiring a first image matting image.
In step S3, the code fusion is performed on the reflection map of the spatial effect image and all the illuminations, and the transparency display is performed on the obtained fusion map, so that the generation of the shadow reflection map includes:
obtaining a space effect image, taking a reflection image of the space effect image as a picture frame of a rendering space, and adding a black transparency mask;

In step S4, rendering the first matte image into a spatial effect image consistent with the illumination attribute of the preset target image includes:
the illumination attribute is a transparency parameter; transparency (transparency) means that light can pass through an object. When rendering transparent objects, it is not sufficient to render only the primitives with the smallest depth values, as it may be necessary to see the following primitives through those primitives. The color of the pixel in the rendered image may be formed by mixing the color of the transparent primitive with the color of one or more other primitives. Typically, the rendered image is constructed by blending multiple layers of transparent objects starting with primitives having the largest depth values and ending with primitives having the smallest depth values. Not all rendering systems are capable of classifying transparent objects, so that software applications are often required to render primitives that are pre-ordered in a back-to-front order. In one example of transparency processing, transparent primitives are processed in ISP 102 (e.g., to determine whether they are hidden behind existing non-transparent objects at arbitrary sample locations), and a tag buffer is flushed behind each transparent primitive to enable the primitive to be textured and shaded, and mixed with previously textured and shaded primitives in a pixel buffer. If the application sends additional non-transparent primitives after the transparent primitive, the result of the blending can be hidden.
When the illumination attribute is defined as a transparency parameter, converting the first matt image from an RGB color space to a luminance and chrominance YUV color space; and converting the transparency parameter of the first matt image into the transparency parameter consistent with the preset target image.
