into an Actor.  This allows you to create predefined gestures for the
object, which can be blended in arbitrary combinations and automatically
morphed between.

used as a tool for shaping the mesh (with forward and inverse kinematics),
and also allows morphing between gestures to happen in a more natural way.
- Added an Array tool (written by Rick van der Meiden) for creating evenly
spaced copies of objects.
- Position, Rotation, and Constraint tracks can now be relative to any
object (or, if it is a mesh, to any bone in its skeleton), not just to the
immediate parent object.
- Texture parameters can now be specified on a per-object basis, as well
as per-vertex.
- Added Texture Parameter tracks which allow you to animate the values
of per-object texture parameters.
- Texture mapping coordinates can now be bound to the vertices of a mesh,
so that the texture will distort with the mesh.
- The Move, Rotate, and Resize tools, as well as the Transform Object
command, offer new options to specify how they interact with parent-child
hierarchies and to set the center for rotation/scaling.
- The file format is now finalized.  This means that files created with this
version are guaranteed to be openable by later versions.
- Many, many bug fixes and other minor improvements.

v0.9, Aug. 25, 2001

Where do I begin?  This version introduces animation, which touches (or
will touch) almost every part of the program in one way or another.
- Each object may have any number of animation tracks, which are applied
according to their individual weight curves.  Current track types include 
Position, Rotation (XYZ and quaternion), Visibility, and Constraint.
- The Score provides a user interface for viewing and editing tracks and
keyframes.
- A Preview Animation command allows you to quickly render and view
wireframe tests of animation sequences.

modify large numbers of keyframes at once.
- A Set Path from Curve command allows you to create animation paths
from curve objects.
- Any object can now be made a child of any other object by dragging it
within the Object List, which is now a hierarchical display.
- I have eliminated the Group and Ungroup commands.  They caused problems
for animation, and the parent-child relationships described above offer
a more powerful way of doing the same things.
- There are several new modules in the procedural texture and material
editor.  The most important of these is the Expression module (written
by David Turner), which allows you to enter arbitrary mathematical
expressions to be evaluated.  Others are Min, Max, Lighter, and Darker
(the last two also by David Turner).  In addition, the Cells module now
offers a choice of three different distance metrics.
- Added a "tolerant selection mode" in the triangle mesh editor.

and materials from files.

- Added a tool for moving vertices inward or outward along the local
surface normal.
