View3ds 0.074 - tiny viewer to .3ds and .asc files with several graphics

                effects implementation.



What's new?

1. Fixed emboss bug in grd lines displaying model.

2. Grd line exceedes screen problem fix.

3. New rendering model - ray casted shadows and appropiate button to

   set 'on' this option. Note that is non real time model, especially when

   complex object is computed. I took effort to introduce accelerating

   structure - AABB (Axis Aligned Bounding Boxes).. but it is disabled 
   for now - seems to work incorrect(slow).





Buttons description:

1.  rotary: choosing rotary axle: x, y, x+y.

2.  shd. model: choosing shading model: flat, grd (smooth), env (spherical

    environment mapping, bump (bump mapping), tex (texture mapping),

    pos (position shading depend), dots (app draws only points - nodes of object),

    txgrd (texture mapping + smooth shading),  2tex (texture mapping + spherical

    environment mapping), bmap (bump + texture mapping),  cenv (cubic environment

    mapping), grdl (Gouraud lines - edges only), rphg (real Phong), glas (glass effect),

    ptex (real Phong + texturing + transparency).

3.  speed: idle, full.

4,5. zoom in, out: no comment.

6.  ray shadow: calc ray casted shadows.

7.  culling: backface culling on/ off.

8.  rand. light: Randomize 3 unlinear lights( so called Phong's illumination).

9.  Blur: blur N times; N=0,1,2,3,4,5

10.11,12,13. loseless operations (rotary 90, 180 degrees).

12. emboss: Do emboss effect( flat bumps ), use 'bumps deep' button to do edges

     more deep.

13. fire: do motion blur ( looks like fire ).

14. move: changes meaning x,y,z +/- buttons  ->  obj: moving object, camr: moving

      camera, wave: x,y +/- increase, decrease wave effect frequency and amplitude.

15. generate: Generates some objects: node, Thorn Crown, heart...

16. bumps: random, according to texture.

17. bumps deep -> create bumps deeper or lighter.

18. re-map tex -> re-map texture and bump map coordinates, to change spherical

     mapping  around axle use 'xchg' and 'mirror' buttons, then press 're-map tex' button.

19. bright + -> increase picture brightness.

20. bright - -> decrease picture brightness.

21. wav effect -> do effect based sine function.

22. editor -> setting editing option. If is "on" then red bars are draw according to each

   vertex, Pressing  and moving left mouse button (cursor must be on handler)- change

   vertex position. If left mouse button is released apply current position. You may also

   decrease whole handlers count by enable culling (using appropriate button) - some

   back handlers become hidden.
