Expand description

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).

\param renderer The rendering context. \param texture (optional) The SDL texture to use. \param vertices Vertices. \param num_vertices Number of vertices. \param indices (optional) An array of integer indices into the ‘vertices’ array, if NULL all vertices will be rendered in sequential order. \param num_indices Number of indices. \return 0 on success, or -1 if the operation is not supported

\since This function is available since SDL 2.0.18.
