Hi AppleCider,
Bryce requires no math at all bud.
Just jump on in and start picking scene options, and creating your objects using the primary shapes, or the premade models that are included with the program.
About the only thing needed to learn for making objects with Bryce, is the Boolean operations. But those are actually quite simple once you read a little about them.
Here's some basic info on that:[list]
Boolean Union = the joining/merging of more than one object/shape.
Boolean Difference = subracting one object/shape from another, and ending up with the
Difference between the 2.
i.e. ending up with the area where the 2 shapes were touching. Boolean Subtract = subtracting the area of one object with another;
i.e. by using a 2nd object to cut away a sections of the first one.[/list:u] And there are a few more as well. But do a little reading about this cool function -
Boolean Operations - and you'll be creating scenes in Bryce in no time. Also checkout Bryce tutorial sites around the Web; there are a lot of them.
