In order to built 3D Engines using an API like DX or OpenGL do you have to know math at all,some or advanced?

YES!!!

Maths are quite important for calculating normals and rotations... you can probably manage by copy-pasting quite some code and using it in general purpose classes (like I did), but I believe that at some point you need the maths to create pretty effects and derive functions for specific functions.
It mostly depends on what you want to do.

I''m not that experienced in making engines, but that is what I experience so far.

You won''t go anywhere without linear algebra and trigonometry.

Documents [ GDNet | MSDN | STL | OpenGL | Formats | RTFM | Asking Smart Questions ]
C++ Stuff [ MinGW | Loki | SDL | Boost. | STLport | FLTK | ACCU Recommended Books ]

Unless you use a ready made 3D Engine that has all the math ready and functions in which case you only have to program the game without the use of math.

Yes, but there''s always going to be some maths... Maths really isn''t bad though, I''ve never understood why people claim they ''can''t do it'' and ''hate it''. Programming isn''t point and click.
