  7. This software package was developed to provide the tools needed to 
  8. construct, visualize, and interact with a virtual environment.  The environment
  9. is generated from a series of primitives called models which are linked
  10. together and controlled through a hierarchial display map to create objects.
  11. There can be multiple objects and any number of nodes (action blocks) within
  12. a single object that link the primitives together.
  13.     The view into the environment is controlled through a view structure
  14. which when reconfigured is used to display the next frame of graphics. The 
  15. view is a simple "camera" implimentation using spherical coordinates and
  16. parameters for far and near clipping planes.
  17.     Other functions available in the library include a pause function and
  18. a getinput function.  The get input function will grab a character from the
  19. keyboard in a wait or nowait mode.
  20.     The current implimentation of the renderer only supports drawing
  21. a wireframe output.  Clipping is done on a "whole" polygon basis which
  22. means that if any of a poly's verticies are outside the clipping limits 
  23. (view volume) then the entire poly is removed.  This can create annoying 
  24. visual artifacts if a poly is very large and near to the viewpoint.
  25.     The library uses a floating point environment and therefore requires
  26. a math coprocessor to attain usable frame rates.  To give an example of speed, 
  27. a scene with 18 objects composed of 261 verticies (217 polys) is rendered 1000 
  28. times.  While each frame is rendered, the viewpoint is moved around the scene. 
  29. On an A4000/040, this demo completes in 50 sec which is an average of 20fps.
  30. On any other machine, the frame rate is usually less than half.  This is due
  31. to the 040's ability to do FPU operations in parallel with CPU operations.
  32.     The library is not very useful on anything except an 040 based machine
  33. because of the floating point environment.  It will multitask well with the 
  34. operating system and doesn't hog the blitter.  The code is really just a small
  35. hack I wrote a while ago!  I am working on a much larger C++ VR Toolkit for
  36. the AMIGA.  The toolkit will be an extensive collection of classes and 
  37. functions that will allow easy construction of interactive 3d environments.
  38. If you are interested in the development of a public domain VR Toolkit for
  39. the AMIGA, read the notice in this release and respond to it!  I am looking 
  40. for talented people who are interested in the development of powerful PD (and
  41. possibly beyond) VR authoring software for the AMIGA.
