Constructor & Destructor Documentation

◆ MeshGrobTransformSubset()

OGF::MeshGrobTransformSubset::MeshGrobTransformSubset ( MeshGrobTransformTool * parent )

MeshGrobTransformSubset constructor.

Parameters

[in] parent a pointer to the MeshGrobTransformTool (MultiTool) this MeshGrobTransformSubset belongs to.

Member Function Documentation

◆ grab()

void OGF::MeshGrobTransformSubset::grab ( const RayPick & p_ndc )

override

◆ update_transform_subset()

void OGF::MeshGrobTransformSubset::update_transform_subset ( const mat4 & M )
