Detailed Description

\inmodule QtGui

Since

6.6

Compute pipeline state resource.

Note

Setting the shader resource bindings is mandatory. The referenced QRhiShaderResourceBindings must already have created() called on it by the time create() is called.

Setting the shader is mandatory.

This is a RHI API with limited compatibility guarantees, see \l QRhi for details.

Member Function Documentation

create()

virtual bool QRhiComputePipeline::create ( )

pure virtual

Implemented in QD3D11ComputePipeline, QGles2ComputePipeline, QMetalComputePipeline, QNullComputePipeline, and QVkComputePipeline.

Referenced by QSSGRhiContextPrivate::computePipeline().

Here is the caller graph for this function:

flags()

QRhiComputePipeline::Flags QRhiComputePipeline::flags ( ) const

inline

Returns

the currently set flags.

Definition at line 1632 of file qrhi.h.

resourceType()

QRhiResource::Type QRhiComputePipeline::resourceType ( ) const

overridevirtual

Returns

the resource type.

Implements QRhiResource.

Definition at line 7865 of file qrhi.cpp.

References QRhiResource::ComputePipeline.

setFlags()

void QRhiComputePipeline::setFlags ( Flags f )

inline

Sets the flags f.

Definition at line 1633 of file qrhi.h.

setShaderResourceBindings()

void QRhiComputePipeline::setShaderResourceBindings ( QRhiShaderResourceBindings * srb )

inline

Associates with srb describing the resource binding layout and the resources (QRhiBuffer, QRhiTexture) themselves.

The latter is optional. As with graphics pipelines, the srb passed in here can leave the actual buffer or texture objects unspecified (\nullptr) as long as there is another, \l{QRhiShaderResourceBindings::isLayoutCompatible()}{layout-compatible} QRhiShaderResourceBindings bound via \l{QRhiCommandBuffer::setShaderResources()}{setShaderResources()} before recording the dispatch call.

Referenced by QSSGRhiContextPrivate::computePipeline().

Here is the caller graph for this function:

setShaderStage()

void QRhiComputePipeline::setShaderStage ( const QRhiShaderStage & stage )

inline

Sets the shader to use.

stage can only refer to the \l{QRhiShaderStage::Compute}{compute stage}.

Here is the caller graph for this function:

shaderResourceBindings()

QRhiShaderResourceBindings * QRhiComputePipeline::shaderResourceBindings ( ) const

inline

Returns

the currently associated QRhiShaderResourceBindings object.

Definition at line 1638 of file qrhi.h.

shaderStage()

QRhiShaderStage QRhiComputePipeline::shaderStage ( ) const

inline

Returns

the currently set shader.
