Notes for April 14 class
|
Using a 3D modeling package
In class on Thursday we
took a tour through
my WebGL based 3D modeling package
CT_Modeler.js,
the same one I implemented for Chalktalk.
There are fancier packages out there, but for our
purposes in this class, this package has
the advantage of being relatively small
(just a few hundred lines of Javascript code),
and therefore not that difficult to read
through and understand.
The modeling package itself, as well as the
simple example that we developed
in class, are in
code5.zip.

Homework, due by start of class on Thursday April 21
This is going to be a relatively simple homework,
but it is extremely important that you complete it,
because otherwise you will find it much more difficult
to complete the homework which will follow after this one.
-
Look through the source code to
CT_Modeler.js,
and familiarize yourself with it.
-
Make your own simple scene.
See if you can make an object hierarchy of
some sort, using relative matrix transformations
at each node of your hierarchy just as I did
in class.
Try out different shapes from the assortment of
shapes in the modeling package, and see what you
can come up with.
Also try different materials.
Don't just do a swinging arm example -- I already did
that in class. But feel free to expand out to an
entire human body if you'd like.
