Detailed Description

RotationalSpringEffect is a localized haptic effect where the haptics device is rotated towards a certain axis of rotation in a spring like manner i.e.

the torque is proportional to the the angle between the desired axis and the rotated default axis ( 0, 0, 1 ). The default axis is rotated by the haptics device orientation. deviceIndex decides on which haptics device this effect should be on. The force generated will be

Member Data Documentation

◆ damping

H3DUniquePtr< SFFloat > H3D::RotationalSpringEffect::damping

The damping constant to use in the torque calculation.

NOTE: Currently not used at all.

Access type: inputOutput
Default value: 0

Referenced by RotationalSpringEffect(), and traverseSG().

◆ desiredAxis

H3DUniquePtr< SFVec3f > H3D::RotationalSpringEffect::desiredAxis

The desired axis of the spring, that is the axis towards which the torque should be directed.

Access type: inputOutput
Default value: Vec3f( 0, 0, 1 )

Referenced by RotationalSpringEffect(), and traverseSG().

◆ enabled

H3DUniquePtr< SFBool > H3D::RotationalSpringEffect::enabled

The enabled field should be set to true when the force effect should be enabled and active.

Access type: inputOutput
Default value: TRUE

Referenced by RotationalSpringEffect(), and traverseSG().

◆ springConstant

H3DUniquePtr< SFFloat > H3D::RotationalSpringEffect::springConstant

The spring constant of the spring.

torque = spring_constant * base_torque Where base torque is the vector part of a quaternion created from the rotation difference between the current defaul device axis and the desired axis.

Access type: inputOutput
Default value: 100

Referenced by RotationalSpringEffect(), and traverseSG().

◆ torque

H3DUniquePtr< MFVec3f > H3D::RotationalSpringEffect::torque

The torque applied by the spring to the haptics device since the last scenegraph update.

Access type: outputOnly
Default value: Vec3f( 0, 0, 0 )
