SDL_GPUPrimitiveType

Specifies the primitive topology of a graphics pipeline.

If you are using POINTLIST you must include a point size output in the vertex shader.

- For HLSL compiling to SPIRV you must decorate a float output with [[vk::builtin("PointSize")]]. - For GLSL you must set the gl_PointSize builtin. - For MSL you must include a float output with the [point_size] decorator.

Note that sized point topology is totally unsupported on D3D12. Any size other than 1 will be ignored. In general, you should avoid using point topology for both compatibility and performance reasons. You WILL regret using it.
