Detailed Description

Welcome to the GhoulyPrimitives library the main purpose of this library is to create "primitives", simple geometric objects like sphere, ellipsoid, cone, cylinder... this library is by default bound to ogre, but that can be changed easily, as the geometry generation is implemented independantly generation of geometric data has been seperated from usage of such data (e.g. rendering) generators for geometric are derived from the "Primitive" class users of such data are derived from the "Drawer" class thus it is possible to use the same data for different purposes, for example :

• Drawing the Data on a 3dCard, the "OgreRenderableDrawer" does that (actually it rather transfers the data to vertex and index buffers)
• Generating Mesh Data, so it can be saved to disk, the "OgreMeshDrawer" class will do that, but it is not finished yet
• Constructing Complex Objects from Base data, for example a bunch of 3d-Steel-Pylons from Lines also using something like the DesignPattern "Decorator" it is possible to have a stack of Drawers, representing a processing pipe before sending the data to the 3d Card, this can be used for position or texcoord based coloring and transformation, or "SpaceWarps" like twisting a mesh around the z Axis, based on the z coordinate of the vertices (Warning ! Vertex Colors are not yet implemented here)

this library is not yet finished, but i think it is useful already Questions and Comments are welcome, just drop me an eMail to ghoulsblade@schattenkind.net i'm interested to see where this lib is used if you like spacegames, you might want to visit the project i'm currently working on : http://sfz.schattenkind.net for more code snippets for c++, php and other languages, visit my homepage http://ghoulsblade.schattenkind.net

Have fun =)
