Detailed Description

The scalar viscosity mode generates viscosity throughout a scalar volume.

X3D Interface
	Name	Type	Default value	Description
	viscosity	SFTransferFunction	null	The volume viscosity
	velocityIndependent	SFBool	true	If true the viscosity feedback is not dependent on the velocity, i e the viscosity is expressed in pure Newton as opposed to Newton per meters per seconds.
	snapdrag	SFBool	false	Use the snapdrag effect.
Derived from VHTKScalarModeNode
	scalarVolume	SFScalarVolume	null	The volume to specify the material properties from
Derived from VHTKHapticModeNode
	active	SFBool	TRUE	Specifies if this haptic mode should be active or not

Member Data Documentation

auto_ptr< H3D::ThreadSafeRefSField< SFTransferFunction > > VHTK::ScalarViscosityMode::viscosity

The viscosity to generate.

auto_ptr< H3D::ThreadSafeSField< H3D::SFBool > > VHTK::ScalarViscosityMode::velocityIndependent

If true the viscosity feedback is not dependent on the velocity, i e the viscosity is expressed in pure Newton as opposed to Newton per meters per seconds.

auto_ptr< H3D::ThreadSafeSField< H3D::SFBool > > VHTK::ScalarViscosityMode::snapdrag

Use snapdrag effect.

Observe that the snap-drag effect is undefined for velocity dependent viscosity.
