SDL_RenderGeometryRawFloat

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 and SDL_SetTextureAlphaMod are ignored).

Header File

Defined in <SDL3/SDL_render.h>

Syntax

int SDL_RenderGeometryRawFloat(SDL_Renderer *renderer,
                   SDL_Texture *texture,
                   const float *xy, int xy_stride,
                   const SDL_FColor *color, int color_stride,
                   const float *uv, int uv_stride,
                   int num_vertices,
                   const void *indices, int num_indices, int size_indices);

Function Parameters

SDL_Renderer * renderer the rendering context.
SDL_Texture * texture (optional) The SDL texture to use.
const float * xy vertex positions.
int xy_stride byte size to move from one element to the next element.
const SDL_FColor * color vertex colors (as SDL_FColor).
int color_stride byte size to move from one element to the next element.
const float * uv vertex normalized texture coordinates.
int uv_stride byte size to move from one element to the next element.
int num_vertices number of vertices.
const void * indices (optional) An array of indices into the 'vertices' arrays, if NULL all vertices will be rendered in sequential order.
int num_indices number of indices.
int size_indices index size: 1 (byte), 2 (short), 4 (int).

Return Value

(int) Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.

Version

This function is available since SDL 3.0.0.
