# SDL_RenderGeometryRaw

Render a list of triangles, optionally using a texture and indices into the vertex arrays Color and alpha modulation is done per vertex ([SDL_SetTextureColorMod](SDL_SetTextureColorMod) and [SDL_SetTextureAlphaMod](SDL_SetTextureAlphaMod) are ignored).

## Header File

Defined in [SDL_render.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_render.h)

## Syntax

```c
int SDL_RenderGeometryRaw(SDL_Renderer *renderer,
                       SDL_Texture *texture,
                       const float *xy, int xy_stride,
                       const SDL_Color *color, int color_stride,
                       const float *uv, int uv_stride,
                       int num_vertices,
                       const void *indices, int num_indices, int size_indices);
