SDL_PushGPUVertexUniformData

Pushes data to a vertex uniform slot on the command buffer.

Header File

Defined in <SDL3/SDL_gpu.h>

Syntax

void SDL_PushGPUVertexUniformData(
    SDL_GPUCommandBuffer *command_buffer,
    Uint32 slot_index,
    const void *data,
    Uint32 length);

Function Parameters

SDL_GPUCommandBuffer *	command_buffer	a command buffer.
Uint32	slot_index	the vertex uniform slot to push data to.
const void *	data	client data to write.
Uint32	length	the length of the data to write.

Remarks

Subsequent draw calls will use this uniform data.

The data being pushed must respect std140 layout conventions. In practical terms this means you must ensure that vec3 and vec4 fields are 16-byte aligned.

Version

This function is available since SDL 3.2.0.
