Dex3D2
A sphere rendered with Dex3D2's default gouraud shader.
About
Dex3D2 is an open-source 3d engine written in pure c++. It is the official new release of Dex3D, which debuted in '99. The new engine will come in the form of a Windows DLL, however it will export its triangle function so that custum shaders may be coded for other specific platforms / hardware. Basically, VT only handles vertex coordinate calculation and facet shading. The actual rasterization and pixel plotting is done by the programmer. Of course, a default GDI shader will be supplied in the final release. It should run right out of the box.
(note: VT doesn't mean anything.. it just sounds cool)

Macros
These macros are used by modules Vector and Matrix. They are defined in module Misc. Should you want to use Vector and Matrix without including Misc in its entirety, copy-and-paste this code into a header file in your project.
| #define randEx(lower, upper) ((float) rand() / RAND_MAX * (upper - lower + 1) + lower) #define PI ((float) 3.14159) #define toDegree(angle) (angle * 180 / PI) #define toRadian(angle) (angle * PI / 180) |
Technology
Unlike its predecessor, Dex3D2 will feature a strong modular design. Programmers can choose any level of abstraction they are confortable with in the application and custumization of the engine. Not that modifications are even necessary. VT still supports the same spectrum of functionality as the older version, not to mention a whole new arsenal of cool effects made possible only through the use of c++.

This is the VB source used to produce the sphere screenshot.

(note: it looks like a lot, but that's only because there's three lights)
