Probably very simple to most, but how do you create normals.
Example
----------------------------------------------------------------------
QuadArray face = new QuadArray(4, QuadArray.COORDINATES|QuadArray.NORMALS);
face.setCoordinates(0,coordinateArray);
/*
How do you calaculate normals for each of the four quad points
i.e. What is the mathamatics behind creating normals, and how you
I do this using the math classes of Java3D
*/
face.setNormals(0,normalsArray);
Shape3D myShape = new Shape3D(face);
----------------------------------------------------------------------
I understand what normals are, and what they do, but I don't know how to
create them. Could anyone explain what I need to do, with a simple example.
Thanks, Domas
