NAME¶

SDL_RenderGeometry - 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.

RETURN VALUE¶

Returns true on success or false on failure; call SDL_GetError() for more information.

THREAD SAFETY¶

This function should only be called on the main thread.

AVAILABILITY¶

This function is available since SDL 3.2.0.
