sdlxBindGpuFragmentStorageTextures function gpu

void sdlxBindGpuFragmentStorageTextures(Pointer<SdlGpuRenderPass> renderPass, List<Pointer<SdlGpuTexture>> storageTextures, { int firstSlot = 0, })

Binds storage textures for use on the fragment shader.

These textures must have been created with SDL_GPU_TEXTUREUSAGE_GRAPHICS_STORAGE_READ.

The textures being bound must have a matching type declared in the shader (2D, 3D, 2DMS, etc.)

Be sure your shader is set up according to the requirements documented in SDL_CreateGPUShader().

\param render_pass a render pass handle. \param first_slot the fragment storage texture slot to begin binding from. \param storage_textures an array of storage textures. \param num_bindings the number of storage textures to bind from the array.

\since This function is available since SDL 3.2.0.
