详细描述
QComponent to issue work for the compute shader on GPU
A Qt3DRender::QComputeCommand is used to issue work for the compute shader. The compute shader is specified in the QMaterial component of the same entity the QComputeCommand is added to. The workGroupX, workGroupY and workGroupZ properties specify the work group sizes for the compute shader invocation. Qt3DRender::QDispatchCompute node needs to be present in the FrameGraph to actually issue the commands.

成员函数
QComputeCommand::QComputeCommand(Qt3DCore::QNode *parent = nullptr)
The constructor creates a new Qt3DRender::QComputeCommand instance with the specified parent.
[slot] void QComputeCommand::setWorkGroupX(int workGroupX)
Sets the workgroup for the first dimension to workGroupX.
Note: Setter function for property workGroupX.
参见 workGroupX().
[slot] void QComputeCommand::setWorkGroupY(int workGroupY)
Sets the workgroup for the second dimension to workGroupY.
Note: Setter function for property workGroupY.
参见 workGroupY().
[slot] void QComputeCommand::setWorkGroupZ(int workGroupZ)
Sets the workgroup for the third dimension to workGroupZ.
Note: Setter function for property workGroupZ.
参见 workGroupZ().
