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).
int SDL_RenderGeometry(SDL_Renderer *renderer,
SDL_Texture *texture,const SDL_Vertex *vertices, int num_vertices,
const int *indices, int num_indices);
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. |
Return 0 on success, or -1 if the operation is not supported
