SDL_RenderGeometry3
Render a list of triangles, optionally using a texture and indices into the vertex array color and alpha modulation is done per vertex ( sdl_settexturecolormod and sdl_settexturealphamod are ignored).
Usage
#include "SDL3/SDL.h"
bool SDL_RenderGeometry(SDL_Renderer *renderer, SDL_Texture *texture, const SDL_Vertex *vertices, int num_vertices, const int *indices, int num_indices);
Header file
