Enum wgpu::LoadOp

source ·
pub enum LoadOp<V> {
    Clear(V),
    Load,
}
Expand description

Operation to perform to the output attachment at the start of a render pass.

Corresponds to WebGPU GPULoadOp, plus the corresponding clearValue.

Variants§

§

Clear(V)

Loads the specified value for this attachment into the render pass.

On some GPU hardware (primarily mobile), “clear” is significantly cheaper because it avoids loading data from main memory into tile-local memory.

On other GPU hardware, there isn’t a significant difference.

As a result, it is recommended to use “clear” rather than “load” in cases where the initial value doesn’t matter (e.g. the render target will be cleared using a skybox).

§

Load

Loads the existing value for this attachment into the render pass.
