[Gambas-user] angle interpolation algorithm troubles

[Randall Morgan]

My Game programming days go back to DOS and WinG and the last thing I
worked on was using DirectX 6 and it was brand new then. Much has changed
since then. Even C and C++ and the coding styles used now are completely
different. So I am glad this old man could help!

If you ask me if it can be done. The answer is YES, it can always be done.
The correct questions however are... What will it cost, and how long will
it take?
