SDL_GPUPrimitiveType3type
Specifies the primitive topology of a graphics pipeline.
Usage
#include "SDL3/SDL.h"
typedef enum SDL_GPUPrimitiveType { SDL_GPU_PRIMITIVETYPE_TRIANGLELIST, /**< A series of separate triangles. */ SDL_GPU_PRIMITIVETYPE_TRIANGLESTRIP, /**< A series of connected triangles. */ SDL_GPU_PRIMITIVETYPE_LINELIST, /**< A series of separate lines. */ SDL_GPU_PRIMITIVETYPE_LINESTRIP, /**< A series of connected lines. */ SDL_GPU_PRIMITIVETYPE_POINTLIST /**< A series of separate points. */ } SDL_GPUPrimitiveType;
Header file
Defined in SDL3/SDL_gpu.h
Overview
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.
