Detailed Description
The CoordinateDeformer uses a H3DFunctionNode to determine the deformation.
The distanceToDepth field specifies a function from the distance from the point of contact to the depth of the deformation. The depth is defined as a float 0 is no deformation at all, and 1 will result in a deformation that is as deep as penetration depth of the surface (i.e. the distance the haptics device has penetrated the surface.
The plasticity field defines the plasticity. 0 means that the deformation is non-plastic (resting points will not be changed) and 1 means that it is fully plastic (resting points will be the same as deformed points) Examples:
Member Data Documentation
◆ deviceAlgorithm
| H3DUniquePtr< SFString > H3D::CoordinateDeformer::deviceAlgorithm |
The deviceAlgorithm field contains a string that controls how the deformation is calculated for a coordinate when several devices are in use.
The allowed values are: "MAX" - The biggest deformation of a coordinate is chosen. "AVG" - An average of the deformation from each device for a coordinate is calculated.
Access type: inputOutput Default value: "MAX"

◆ distanceToDepth
| H3DUniquePtr< SFFunctionNode > H3D::CoordinateDeformer::distanceToDepth |
The distanceToDepth field specifies a function from the distance from the point of contact to the depth of the deformation.
The depth is defined as a float 0 is no deformation at all, and 1 will result in a deformation that is as deep as penetration depth of the surface (i.e. the distance the haptics device has penetrated the surface.

◆ plasticity
| H3DUniquePtr< SFFloat > H3D::CoordinateDeformer::plasticity |
The plasticity field defines the plasticity.
0 means that the deformation is non-plastic (resting points will not be changed) and 1 means that it is fully plastic (resting points will be the same as deformed points)
