View3ds 0.072 - tiny viewer to .3ds and .asc files with several graphics
effects implementation.
What's new?
1. New displaying model - texturing with bilinear filtering and transparency
simultanusly. Note that filtering is done only inside polygon. To better
quality of image there is a need to use floats coordinates of texture to pass
as arguments to single triangle rendering proc.
2. Optimizations.
3. SSE3 version runs correct on SSE2 cpus, but real phong, glass and
transparented texturing with filtering rendering models are disabled.
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. catmull: disabled
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.
