Depot Games: AllegroPak Demos
Project Status: Abandoned Highest Popularity: #14 during May 2007 Links: Web Site Category: Demos Developers: Andrei Ellman Ports: DOS Source Code: Available Author's Description: The AllegroPak demos are two pre-built demos showing what can be done with the now abandoned AllegroPak add-on. The demos have not been updated since 1997. SPH_DEMO.EXE demonstrates lit Z-buffered texture-mapped 3D spheres and contains three parts. In the first part, there are four z-buffered gouraud-shaded pyramids with a hole in them (the hole is defined by the transparent colour on the texture). The second part demonstrates a good use of the HSL colourspace to add a rainbow to a single light-sourced pyramid rendered using light-mapped paletted gouraud-shaded rendering. The different lightness levels have been given a hue. You can change the saturation and the 'hue-twist'. The third part is where it gets interesting. It is real-time light-sourced Z-buffered spherical rotated texture mapping using real spheres (as opposed to spherical polygon-meshes). How the spheres are rendered, and where the light comes from can be controlled. The light-source can either be a point which the user can move around, or an infinitely-far light which the user can rotate. 3DSPDEMO.EXE demonstrates a 3D environment with Z-buffered translucent 3D sprites both with and without depth-maps and fog-shading in 8-bit colour.
