SDL_RenderGeometryRaw3
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).
Usage
#include "SDL3/SDL.h"
bool SDL_RenderGeometryRaw(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);
Header file
Defined in SDL3/SDL_render.h
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 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.
