Introduction

VoxRend will be a voxeled graphic engine, simple but powerful, to build 3D games easily.

VoxRend doesn't try to be better than current game engines. Even it uses some techniques clasified as obsolete, such as ray-cast, so it won't break any record. Anyway, you would find it useful and funny, specially if you're an amateur game developer.

Actually the engine is under development (WIP or Work In Progress) so it isn't fully functional. Here you have a list with some planned features:

Full source code avaiable. This way, you'll know how it works.
Tilemap based.
Floor and ceilings with and without paralax effects.
Fully voxeled objects (actually done but buggy).
VOX object tools included. VOX is a file format that describes an object builded with voxels. This format was used in games as Blood or Shadow Warrior and the latest ports of Duke Nukem 3D.
Fog effect fully configurable.
Generic map editor.

UOVLR

UOVLR means for "UnOptimised Voxel Landscape Renderizator". It is a small program to demonstrate the algorithm used by the VoxRend renderer. It's very simple and includes a lot of comments and documentation. You should download it if you want to understand the sources of VoxRend.

License

VoxRend is giftware. You may use, modify, redistribute, and generally hack it about in any way you like. You don't have to send the authors anything in return, but of course you're welcome to do so. This could be a complimentary copy of a game, an addition or improvement to VoxRend, a bug report, some money (this is particularly encouraged if you use VoxRend in a commercial product), or just an email saying "Hi!". If you redistribute parts of VoxRend, or make a game using it, it would be nice if you mentioned VoxRend in the credits, but if you just want to pinch a few code lines or techniques then that's fine too.

However, please do not distribute modified copies under the name `VoxRend' without stating clearly that they have been modified. Otherwise everybody will just get confused.

Downloads

Here you have the latest downloads avaiable. Visit the VoxRend Sourceforge download page to get the complete list of downloads. Read the chages log for information about changes between versions.

VoxRend 0.22
The VoxRend engine sources. That release has a transitional API. Newer versions (0.3) will define a different one. See the future issues for more information.
UOVLR
The algorithm explamation.

Future issues

Here you have a list of future changes planned. If you want to comment them contact me.

The actual release has a transitional API. There are a new API described for version 0.3 wich is similar than the one used by OpenGL. i.e.: The actual function vr_define_viewport will be vrDefineViewport, vr_move_sprite will be vrMoveSprite3f and vrMoveSprite3i and so.
The actual object render code is a pain, slow and buggy. Future releases will use a c-buffer wich (hopefully) will speed-up and throw out some actual limitations.
There aren't tools for voxel object editing (the only one I've found is "slabspri" by Ken Silverman) so it would be cool to code a new one.
