SDL_RenderGeometry - Man Page

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).

Synopsis

#include <SDL3/SDL_render.h>

bool SDL_RenderGeometry(SDL_Renderer *renderer,
                   SDL_Texture *texture,
                   const SDL_Vertex *vertices, int num_vertices,
                   const int *indices, int num_indices);

Function Parameters

renderer: the rendering context.
texture: (optional) The SDL texture to use.
vertices: vertices.
num_vertices: number of vertices.
indices: (optional) An array of integer indices into the 'vertices' array, if NULL all vertices will be rendered in sequential order.
num_indices: number of indices.
