GSS - Generative Scene Script

--- Under construction and even the name is temporary ---

This is a scripting language intended for easily make maps for 3d games.

It can currently create Wavefront Object (*.obj) for static meshes.

It is currently in alpha development stage and latest version is 0.3.

Some current features:

• math parser (standard operations with precedence + a couple of dozens functions like sin() and rnd()
  
• variables
• simple loops
• macros (work a bit like sub programs or procedures)
• a little over dozen simple commands
• visualization utilizing Irrlicht 3d graphics engine

The main idea behind the creation of 3d maps, is to define some lines and attach textures to them. The location is then moved and with a simple command the lines are pulled to the new place, leaving textured faces behind. In other words. A corridor would be made by defining four lines on vertical plane and the just moving around and a corridor is formed behind.

Example, simple corridor section:

l -.5,  0,  0,   .5, 0, 0, "floortexture" // floor
l  .5, 1, 0, "walltexture"                // wall
l -.5, 1, 0, "ceilingtexture"             // ceiling
l -.5, 0, 0, "walltexture"                // wall
push              // let's push our corridor prototype into storage
move 1            // move a step forward
pull              // pull the lines to this new position and create walls

Simple! The shape need not to be 'pushed' to storage anymore, one could just move around, maybe rotate a bit and then just call pull.
