The tile product can be matched with the space style liked by consumers according to the tile product style, and the panoramic effect of the product in the application space is presented. The service quality provided by a tile merchant when the tiles are sold is greatly improved, the sale is promoted, and important reference can be made for the purchase decision of a consumer through the designed panoramic effect picture.
As shown in fig. 1, the present invention provides a space display method of a tile, the method comprising:
s1, acquiring a pre-established three-dimensional space model;
s2, matting the brick replacing area of the three-dimensional space model to obtain a first matting image;
s3, rendering the first matting image into a space effect image consistent with the preset target image illumination attribute;
s4, carrying out code fusion on the reflection image of the space effect image and all illumination, and carrying out transparency display on the obtained fusion image to generate a shadow reflection image;
and S5, combining and superposing the shadow reflection map, the space effect image and the three-dimensional space model to display the superposition effect in real time.
In step S1, the pre-building 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 a replaceable tile map matched with the three-dimensional space model.
In step S2, the acquiring the first matting image includes:
setting at least one editable area on the three-dimensional space model as a brick replacing area;
selecting a color key to carry out image matting processing on a brick replacing area of the three-dimensional space model to obtain a first image matting image.
In step S3, the code-fusing the reflection map of the spatial effect image with all the illumination, and performing transparency display on the obtained fused map, and generating the shadow reflection map includes:
acquiring 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;

and covering the reflection map of the space effect image on the fusion image, and performing smoothing treatment on the covered image splicing boundary to obtain a shadow reflection map.
In step S4, rendering the first matting image into a spatial effect image consistent with the preset target image lighting attribute 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, since the following primitives may have to be seen through those primitives. The color of a 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 the primitive having the largest depth value and ending with the primitive having the smallest depth value. Not all rendering systems are able to sort transparent objects, often requiring a software application 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 the tag buffer is flushed behind each transparent primitive to enable the primitives to be textured and shaded, and blended with previously textured and shaded primitives in the pixel buffer. If the application sends additional non-transparent primitives after the transparent primitive, the result of the blending may be hidden.
When the illumination attribute is defined as a transparency parameter, firstly converting the first matting image from an RGB color space to a luminance and chrominance YUV color space; and then converting the transparency parameter of the first image matting image into the transparency parameter consistent with the preset target image.

placing the space effect image above the shadow reflection image, and placing the space effect image on the first layer of the screen for display;
and placing the three-dimensional space model below the shadow reflection image and placing the three-dimensional space model at the bottom layer of the screen for displaying.
