Detailed Description

This is an implementation of the SIM_Force interface. This implementation returns a force value that is scaled by the mass of the object receiving the force. No torque is applied. This SIM_Data subclass also implements the SIM_Geometry interface to provide a visualization of the fan and the force it will generate.

virtual void SIM_ForceFan::buildGuideGeometrySubclass ( const SIM_RootData root,
const SIM_Options options,
const GU_DetailHandle gdh,
UT_DMatrix4 xform,
const SIM_Time t 
) const
protectedvirtual

We override this method to create the fan geometry.

Reimplemented from SIM_Data.

virtual SIM_Guide* SIM_ForceFan::createGuideObjectSubclass ( ) const
protectedvirtual

Override this to return a SIM_GuideStatic. The fan geometry is always the same, only the transform changes.

Reimplemented from SIM_Data.

virtual void SIM_ForceFan::getForceOnCircleSubclass ( const SIM_Object object,
const UT_Vector3 position,
const UT_Vector3 normal,
const fpreal  radius,
const UT_Vector3 velocity,
const UT_Vector3 angvel,
const fpreal  mass,
UT_Vector3 force,
UT_Vector3 torque 
) const
protectedvirtual

Override the surface force calculation. This function calls getForceSubclass() to get the force that would be applied to a unit area, then scales this value by the area of the circle that would be presented to the fan.

Reimplemented from SIM_Force.

virtual void SIM_ForceFan::getForceSubclass ( const SIM_Object object,
const UT_Vector3 position,
const UT_Vector3 velocity,
const UT_Vector3 angvel,
const fpreal  mass,
UT_Vector3 force,
UT_Vector3 torque 
) const
protectedvirtual

Override the point force calculations. Since a fan inherently acts on a surface, we assume for points that the point is a surface with unit area.

Reimplemented from SIM_Force.

virtual SIM_ForceSample SIM_ForceFan::getOptimalForceSamplingSubclass ( ) const
protectedvirtual

Allows solvers to query what the optimal sampling type for this force would be. Solvers do not have to respect this. This should be user overrideable so users can trade efficiency for accuracy.
