Enum naga::ConservativeDepth

pub enum ConservativeDepth {
    GreaterEqual,
    LessEqual,
    Unchanged,
}

Enables adjusting depth without disabling early Z.

SPIR-V: ExecutionMode DepthGreater/DepthLess/DepthUnchanged GLSL: layout (depth_<greater/less/unchanged/any>) out float gl_FragDepth;

• depth_any option behaves as if the layout qualifier was not present. HLSL: SV_Depth/SV_DepthGreaterEqual/SV_DepthLessEqual

Variants

GreaterEqual

Shader may rewrite depth only with a value greater than calculated;

LessEqual

Shader may rewrite depth smaller than one that would have been written without the modification.

Unchanged

Shader may not rewrite depth value.
