Struct SDL_GPUPrimitiveType 

#[repr(transparent)]
pub struct SDL_GPUPrimitiveType(pub c_int);

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.

Availability

This enum is available since SDL 3.2.0.
