NAME¶

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 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).

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.

AVAILABILITY¶

This function is available since SDL 3.2.0.
