Examples and How To

Create Object Groups

Create an object group by parenting objects to a group or transform object.

Rotate About an Arbitrary Axis

This example shows how to rotate an object about an arbitrary axis.

Nest Transforms for Complex Movements

This example creates a nested hierarchy of transform objects, which are then transformed in sequence to create a cube from six squares.

Concepts

Object Groups

Group objects are invisible containers for graphics objects. Use group objects to form a collection of objects that can behave as one object in certain respects.

Transforms Supported by hgtransform

The transform object's Matrix property applies a transform to all the object's children in unison.
