Type:         dev/src
Requires:     C Compiler (e.g. gcc), StormMesa
Architecture: m68k-amigaos


21st century and still satisfied with something like

#include <stdio.h>
main ()
{
  printf ("Hello World!\n");
}

as "Hello, World!" ?

No?

So try this!

What about saying hello to the whole damn planet?

This example source shows a textured and animated globe.
You can also activate linear filtering via pulldown menu for
smooth texture (you know this effect well, if you own a Nintendo 64 ;-) )

You can replace the texture "earth_small.rgb" by any SGI rgb texture
- for example a Mars or Venus texture or even a Boing-Ball ;-)

You can modify this source for any purpose.
Ideas:  Use a Moon-texture and add lighting for having a real-time rendered
moon-phase clock. Add names and coordinates of citys and have a 3D-Worldmap.
Implement a gravity routine and place satellites in the orbit.   

The executable included in this archive require 68030 cpu and 68881 fpu or better.
A 68060 or PowerPC CPU and a fast 3D-accelerator is highly recommended.

Testet on Amiga 4000/30 with CyberVision64/3D,
AmigaOS 3.5, CyberGraphX 3, Warp3D 3.
