Member Function Documentation

◆ createFrom()

bool QMetalShadingRateMap::createFrom ( NativeShadingRateMap src )

overridevirtual

Sets up the shading rate map to use a native 3D API shading rate object src.

Returns: true when successful, false when not supported.

Note: This is functional only when the QRhi::VariableRateShadingMap feature is reported as supported, while QRhi::VariableShadingRateMapWithTexture feature is not. Currently this is true for Metal, assuming variable rate shading is supported by the GPU.; With Metal, the object field of src is expected to contain an id<MTLRasterizationRateMap>. Note that Qt does not perform anything else apart from passing the MTLRasterizationRateMap on to the MTLRenderPassDescriptor. If any special scaling is required, it is up to the application (or the XR compositor) to perform that.

Reimplemented from QRhiShadingRateMap.

Definition at line 4171 of file qrhimetal.mm.

◆ destroy()

void QMetalShadingRateMap::destroy ( )

overridevirtual

Releases (or requests deferred releasing of) the underlying native graphics resources.

Safe to call multiple times, subsequent invocations will be a no-op then.

Once destroy() is called, the QRhiResource instance can be reused, by calling create() again. That will then result in creating new native graphics resources underneath.

Note: Resources referenced by commands for the current frame should not be released until the frame is submitted by QRhi::endFrame().

The QRhiResource destructor also performs the same task, so calling this function is not necessary before deleting a QRhiResource.

Implements QRhiResource.
