Enum GpuCommand 

pub enum GpuCommand {
    ClearRenderBuffer {
        render_buffer_id: u32,
    },
    DrawGeometry {
        gpu_state: Box<GpuState>,
        geometry_id: u32,
        indices_offset: u32,
        indices_count: u32,
    },
}

The GPU command to be executed.

This describes a command to be executed on the GPU.

Commands are dispatched to the GPU driver asynchronously via update_command_list, the GPU driver should consume these commands and execute them at an appropriate time.

Variants

ClearRenderBuffer

Clear a specific render buffer, to be prepared for drawing.

Fields

render_buffer_id: u32

The render buffer to clear.

DrawGeometry

Performs a draw command.

Fields

gpu_state: Box<GpuState>

The GPU state to use for the draw command. (contain the render_buffer_id)

geometry_id: u32

The geometry (vertex_buffer/index_buffer pair) to be used for the draw command.

indices_offset: u32

The index offset to start drawing from in the index_buffer.

indices_count: u32

The number of indices to draw.
