Transform3D

• A Transform3D describes the transform used by a TransformGroup

  • Represented as a 4x4 double precision matrix

  • Can represent translation, rotation, scaling, and shear

  • Must be affine (ie, no perspective-like homogeneous division)

• Transforms must be congruent if used in a TransformGroup that is an ancestor of a ViewPlatform (ie, no non-uniform scaling)

Just stay with simple combination and you won't have any trouble

• Transform3D extends the Object class

shear [n.]

(§ Homonym: sheer)
1. A machine that cuts sheet metal by passing a blade through it.
2. (Physics) A deformation of an object in which parallel planes remain parallel but are shifted in a direction parallel to themselves; "the shear changed the quadrilateral into a parallelogram."
