Free classes software for windows

OxMath is an open source 2D/3D math library for REALbasic with ubiquitous vector, quaternion, and axis angle classes, plus vector array classes for efficient vertex/triangle storage and batch processing.
The library also includes bounding volume/intersection classes, and waveform "function" that can be used for procedural animation.

C++ vector and matrix classes for scientific computing designed for general matrix algebra calculations with real numbers. These classes have a rich set of vector and matrix constructors, methods and functions for file input and output in different formats, conversion, matrix inversion, LU and SVD matrix decompositions, matrix exponentiation and solving sets of linear equations.

Realbasic interfaces for FMOD Ex to provide advanced 2D and 3D audio. FMOD Ex Audio Classes will hook into the cross platform FMOD Ex audio library, supporting a wide range of audio formats and playback options, plus physically correct 3D positional audio.
Streams
- Currently these classes do not support disk or network streaming. Be aware that the FMExStream class stores audio data in RAM in its native file format for the lifetime of the object, therefore streams are only practical when using compressed formats, or when stitching is required via the FMExStreamSentence class.
Virtual Channels
- One of FMOD Exs most touted features is automatic channel virtualization. This allows you to play sounds on more channels than are physically available and let FMOD Ex decide which sounds are more important based on priority settings and 3D positioning. One caveat with virtualization is that you must call FMEx.Update as frequently as possible for this to actually work (e.g. in games youd typically call FMEx.Update every frame). NOTE: If youre already calling FMEx.Update for 3D audio you do not need to call it twice.
MIDI
- MIDI playback currently only works on Windows, and only if the default system sound font is installed (/windows/system32/drivers/gm.dls). Broader MIDI support is on the would-like list but primary tests point to a broken implementation on Mac OS X (i.e. some FMOD Ex bugs need to be fixed before this can work).

Class Action Killers brings you a 3D 3rd-person shooter action game. Attorney Max Fees has dispatched his lethal lawyers to destroy the city. You must stop his lawyers and put an end to Max Fees. Be especially careful of the female lawyers as they love to attack from behind. Use your arrow keys and mouse to move, your left mouse button to fire, and your right mouse button to jump. Class Action Killers is now compatible with Windows Vista and is still completely free.

Enhancements :

• Added Windows Vista compatibility and some Vista PCs may need to run the game in Administrator mode.
