SDL_RenderGeometryRaw - Man Page

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).

Synopsis

#include <SDL3/SDL_render.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);

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).
