Raw Blame History

;MOS3DE V 0.1 - MENUETOS 3D Engine V 0.1
; Compile with FASM for MENUET
; this is a very early Version: I'm so happy that it runs at all.
; Of course it's a bad ASM style and it can be optimized a lot.
; anyway - I have thought I uploap this so other PPL might optimize it
; as well or transform it to something completely diffrent.
; There are some Mouse- and Keyboardhandling Subs and Constructs. They are here
; because I will probably use them for the Navigation in a First Person
; Perspective Game - which is the goal of this project.
; http://www.melog.ch/mos_pub/ dietermarfurt@angelfire.com
; of course you can remove or replace them. It has only linear Texturemapping.
; Perspective Correction is a future option.
; a flag for multiple Textures selection should be implemented in the
; Meshfile Format. As I said - it's a very erarly version.
