runType : RunType

Specifies whether the compute command should be performed every frame or manually triggered.

If set to Continuous, Compute command is executed everyframe. This is the default.

If set to Manual CompouteCommand is executed for a given number of frames and then the component disables itself.

Member Function Documentation

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.

See also workGroupX().

[slot] void QComputeCommand::setWorkGroupY(int workGroupY)

Sets the workgroup for the second dimension to workGroupY.

Note: Setter function for property workGroupY.

See also workGroupY().

[slot] void QComputeCommand::setWorkGroupZ(int workGroupZ)

Sets the workgroup for the third dimension to workGroupZ.

Note: Setter function for property workGroupZ.

See also workGroupZ().

[slot] void QComputeCommand::trigger(int workGroupX, int workGroupY, int workGroupZ, int frameCount = 1)

When the run type is set to Manual, calling trigger will make the compute command be executed for the next frameCount frames. Upon completion of the execution, the enabled property will be set to false. The size of the workgroup previously set will be overridden with workGroupX, workGroupY, workGroupZ.

[slot] void QComputeCommand::trigger(int frameCount = 1)

When the run type is set to Manual, calling trigger will make the compute command be executed for the next frameCount frames. Upon completion of the execution, the enabled property will be set to false.
