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.h"

int SDL_RenderGeometryRaw(SDL_Renderer *renderer,
                       SDL_Texture *texture,
                       const float *xy, int xy_stride,
                       const SDL_Color *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_Color )

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.

AVAILABILITY¶

This function is available since SDL 3.0.0.
