Subversion Repositories Kolibri OS

1. New displaying model - glass -  it's two pass rendering. First pass calculates

   Z position of all front pixels, second render image with adding reflective

   component of light only for front pixels. Transparent effect by adding with saturation.

2. I removed bug with performing generation object after choosing 'emboss' option.

-----------------------------------------------------------------------------------

1. Some keys support by Leency.

2. New displaying model - real Phong - real not fake normal vector interpolation,

   normalising it and calculating  dot product (one for each light).

   It requires SSE3.  (by me, Maciej Guba)

-----------------------------------------------------------------------------------

1. KPacked files support by Leency.

2. 32bit vertices indexes and ability to load whole RAM limited objects.

   (Above 65535 vertices and triangles), (by me).

3. I switch off painters algotithm mode (depth sorting). In app impelementetion it has

   limited vertices count and produce less quality image than Z buffer Catmull algo.

   In addition this switch off reduces app size, (by me).

-----------------------------------------------------------------------------------

1. Editing option - new 'editor' button.

2. For now I disable perspective correction, to make implemtation

   of editing option easier.

-----------------------------------------------------------------------------------

1. Sizable app window.

-----------------------------------------------------------------------------------

1. App window size according to current screen resolution.

2. New emboss procedure.

-----------------------------------------------------------------------------------

1. Asc files support.

-----------------------------------------------------------------------------------

1. Bug fixes.

-----------------------------------------------------------------------------------

1. Postprocessing effect - wave. Ability to change amplitude and frequency.

-----------------------------------------------------------------------------------

1. Counter fix by Mario.

2. New drawing model - smooth shaded lines (edges only view) by me.

-----------------------------------------------------------------------------------

1. Two new buttons to increase and decrease brightness.

-----------------------------------------------------------------------------------

1. Header fix by Leency.

2. SSE2 optimizations by me. (Most visable in BUMP_TEX mode.)

-----------------------------------------------------------------------------------

1. Bump and pararell two texture  mapping functions optimizations.

   (files bump_cat.inc & two_tex.inc)

   On my P4 changes are rather non visable, but on dual core in KlbrInWin

   optimizations runs preety nice.

-----------------------------------------------------------------------------------

1. Blur function optimization on SSE and SSE2 (buttons 'blur' and 'fire').

-----------------------------------------------------------------------------------

1. By opening file bigger then ~18 KB, and choosing env mode program terminate.

   I remove this bug

-----------------------------------------------------------------------------------

1. MMX optimizations in 2tex mode (file two_tex.inc).

2. Tiny SSE optimizations (file BUMP_CAT.INC).

3. Bit (two instructions) improved random light generation procedure.

-----------------------------------------------------------------------------------

1. SSE optimizations (file BUMP_TEX.INC).

2. Compiles correctly in newest FASM.

-----------------------------------------------------------------------------------

1. Skinned window by Leency.

2. Optimizations.

3. Re map texture, bumps option - allow spherical mapping around each axle (X,Y,Z).

4. Problem with too small memory to generate object fixed. (Problem ocurred with

   house.3ds object and others objects contains less than 1000 faces and points).

-----------------------------------------------------------------------------------

1. Optimizations.

-----------------------------------------------------------------------------------

1. Memory for file is allocated dynamically.

2. Optimizations.

Note: compiling correct only for KolibriOS.

-----------------------------------------------------------------------------------

1. More smooth texture mapping in tex and txgr shading model and others based on

   tex3.inc, tex_cat.inc shading models.

2. Predefined three, I hope, nice lights.

-----------------------------------------------------------------------------------

1. New shading model: cubic environment mapping with 1.5 kb light buffer.

2. Bumps optionally according to texture. ( It gives so called texture with

   shifts in bumps + texture shading model. )

3. Bumps depth button.

-----------------------------------------------------------------------------------

1. New shading model: bump + texture.  Only version with z coordinate

   interpolation.

2. SSE optimizations ( files: two_tex.inc and bump_tex.inc )

-----------------------------------------------------------------------------------

1. Two shading models: smooth + texture, spherical environment mapping + texture.

   Version only with z coordinate interpolation.

2. Bit changed rotary. I took attempt in SSE instuctions. ( matrix multiplication )

3. Color position depend drawing model  instead spot light ( I hope,spot light come

   back in future ).

-----------------------------------------------------------------------------------

1. New shading models - "spot" - spot light (only one, it's very CPU hungry model,

   and there is no easy way to implement buffer) with light attenuation (In my

   implmentation works not perfect); "dots" - app draws only points (with no culling).

2. Some loseless operations "mirror": according to each axis, rotary 90 degrees.

3. Postprocesing efects: Emboss (use blur to make edges more visable), fire ( be

   carefull during `fire + embos`parallel using).

4. "Move" -  Changes meaning of 'add vector' buttons:

   used "obj"  move  object, "camr" move camera (in this option use culling = 'off'

   I must make culling procedure bit advanced).

5. Generate button. Few objects generating (with bad normals)

6. Some optimizations on MMX.

7. I took an attempt to memory managing functions, but it decreased speed (no aligned

   memory in Menuet functions?)

Greetings for all, especially Madis Kalme for .3ds files support and good vibrations.  ;)

Merry Christmas and happy new year.

-----------------------------------------------------------------------------------

1. Object generating (for now only one). When no parameter specified or error occured

   during reading file from disk, app generate object. No teapot.3ds needed on ramdrive,

   but, if this file exist it would be read as default.

2. Bug in read_from_file procedure fixed. (In  May, when I made shading light vector

   depend, I demaged bit Madis' procedure.)

3. Backface culling on/off option. (Some objects need culling off - they have mismatched

   normal vectors. Example: iron.3ds, sink.3ds, the generated one.)

4. Random lights procedure.

5. Spherical (instead old - planar ) bump, texture mapping.

6. Bit improved menu.

7. Blur.

-----------------------------------------------------------------------------------

Based on earlier demos.

1. 3ds object import as a parameter ( for now only short names supported )

   I updated Kfar app - it can run view3ds with parameter. You must copy it on

   ramdrive. You could do such funny thing: Run updated Kfar in KolbrInWin,

   before them set in KolInWin.ini file path to ramdrive, where yo have "view3ds",

   choose 3ds file ... Emulator will run View3ds with selected file.

   If no parameter specified, app try open tpot.3ds from ramdrive. If tpot.3ds

   don't exist on rd, app hang.

2. Many lights. Every light - unlinear model ( Phong illumination ). For now

   no light setting option.

3. Light buffer for grd, flat model.
