Image rendering method and apparatus, device, medium, and computer program product

A computer device, comprising a memory and one or more processors, the memory storing computer-readable instructions that, when executed by the one or more processors, cause the computer device to perform an image rendering method including:

• determining a vertex coordinate of a virtual texture tile corresponding to an image in a virtual texture;
• loading, through a vertex shader, a physical texture corresponding to the vertex coordinate to a texture cache;
• determining, through the vertex shader for each rendering child tile in the virtual texture tile corresponding to the vertex coordinate, a physical texture coordinate corresponding to each rendering child tile in the texture cache, and transmitting the physical texture coordinate to a pixel shader;
• and
• sampling, through the pixel shader, a texel matched with the physical texture coordinate from the physical texture in the texture cache, and rendering, based on the texel, the image.

One or more non-transitory computer-readable storage media, storing computer-readable instructions that, when executed by one or more processors of a computer device, cause the computer device to implement an image rendering method including:

• determining a vertex coordinate of a virtual texture tile corresponding to an image in a virtual texture;
• loading, through a vertex shader, a physical texture corresponding to the vertex coordinate to a texture cache;
• determining, through the vertex shader for each rendering child tile in the virtual texture tile corresponding to the vertex coordinate, a physical texture coordinate corresponding to each rendering child tile in the texture cache, and transmitting the physical texture coordinate to a pixel shader;
• and
• sampling, through the pixel shader, a texel matched with the physical texture coordinate from the physical texture in the texture cache, and rendering, based on the texel, the image.
