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

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

Return Value

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

Version
