  1. View3ds 0.071 - tiny viewer to .3ds and .asc files with several graphics
  2.                 effects implementation.
  3.  
  4.  
  5. What's new?
  6. 1. New displaying model - glass -  it's two pass rendering. First pass calculates
  7.    Z position of all front pixels, second render image with adding reflective
  8.    component of light only for front pixels. Transparent effect by adding with saturation.
  9. 2. I removed bug with performing generation object after choosing 'emboss' option.
  10.  
  11. Buttons description:
  12. 1.  rotary: choosing rotary axle: x, y, x+y.
  13. 2.  shd. model: choosing shading model: flat, grd (smooth), env (spherical
  14.     environment mapping, bump (bump mapping), tex (texture mapping),
  15.     pos (position shading depend), dots (app draws only points - nodes of object),
  16.     txgrd (texture mapping + smooth shading),  2tex (texture mapping + spherical
  17.     environment mapping), bmap (bump + texture mapping),  cenv (cubic environment
  18.     mapping), grdl (Gouraud lines - edges only), rphg (real Phong).
  19. 3.  speed: idle, full.
  20. 4,5. zoom in, out: no comment.
  21. 6.  catmull: disabled
  22. 7.  culling: backface culling on/ off.
  23. 8.  rand. light: Randomize 3 unlinear lights( so called Phong's illumination).
  24. 9.  Blur: blur N times; N=0,1,2,3,4,5
  25. 10.11,12,13. loseless operations (rotary 90, 180 degrees).
  26. 12. emboss: Do emboss effect( flat bumps ), use 'bumps deep' button to do edges more deep.
  27. 13. fire: do motion blur ( looks like fire ).
  28. 14. move: changes meaning x,y,z +/- buttons  ->  obj: moving object, camr: moving camera, wave: x,y +/- increase,
  29.     decrease wave effect frequency and amplitude.
  30. 15. generate: Generates some objects: node, Thorn Crown, heart...
  31. 16. bumps: random, according to texture.
  32. 17. bumps deep -> create bumps deeper or lighter.
  33. 18. re-map tex -> re-map texture and bump map coordinates, to change spherical mapping
  34.     around axle use 'xchg' and 'mirror' buttons, then press 're-map tex' button.
  35. 19. bright + -> increase picture brightness.
  36. 20. bright - -> decrease picture brightness.
  37. 21. wav effect -> do effect based sine function.
  38. 22. editor -> setting editing option. If is "on" then red bars are draw according to each vertex, Pressing
  39.     and moving left mouse button (cursor must be on handler)- change vertex position. If left mouse button
  40.     is released apply current position. You may also decrease whole handlers count by enable culling (using
  41.     appropriate button) - some back handlers become hidden.
