HI! I''m going to start my journey learning 3D programming, could anyone tell me exactly what branch of math should I study first before learning 3D? If so could you recommend a book or an online tutorial? THANX.

Well, uhh, I would think that you would need atleast geometry, and well it actually depends on your grade... And on the level of 3d you want to go into, but if you just want to make 3d models in 3dsmax and such, no need for anything but a brain!!!

My hobbies:
Martial Arts, Computer/laptop, Listening to Linkin Park, Computer/laptop, programming, game-dev (that''s why the heck I''m on this site in the first place!!! And did I mention my computer/laptop???

He wants to learn 3D programming, not 3D modelling.

To be adept at 3D programming, you need to have a fair knowledge of geometry, trigonometry, and linear algebra (at least general knowledge of matrices, vectors, etc).

OK... nowadays, using complete APIs such as DirectX or OpenGL you can get away without knowing much math. For example, you can blindly use the matrices they provide you with for rotating a 3D model, but to actually UNERSTAND how the matrix is obtained you need to know linear algebra.

I don''t think you''ll be able to get away without knowing any trigonometry, unless you do only the simplest things. I suppose that''s the only REAL requirement, unless you want to be hardcore

Oh, and I suppose intuitive geometry is a must. But hey, that''s common sense stuff I''m talking about.

Hope that helps

Assuming you understand moderate level high school math (trig, algebra, etc.), I''d say linear algebra is a must for 3d programming. For physics, you''ll want to know lots of calculus. For general programming, you''ll want to know discrete mathmatics and algorithms.

anyone know of any good online tuts for math?

3D Math tutorial:

I thought this was easy to understand and comprehensive:

go over to www.free-ed.net. They have quite a few tutorials on the upper level mathematics.
