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).

HEADER FILE

Defined in SDL3/SDL_render.h

SYNOPSIS

#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);

FUNCTION PARAMETERS

renderer

the rendering context.

texture

(optional) The SDL texture to use.

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.

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.
