View3ds 0.076 - XII 2021
|
|
1. Detecting manifold chunks procedure based on kind of sorted pivot
|
|
table. Chunks are counted and this number displayed.
|
|
2. New calculating normal vectors proc that use some data produced
|
|
by new chunks routine. Now big object loading is fast. I load object that
|
|
contains ~500000 vertices, ~700000 faces and ~2000 0000 unique edges
|
|
in few seconds on i5 2cond gen. Earlier such objects calculating was
|
|
rather above time limits.
|
|
3. On http://board.flatassembler.net occasionaly there are some disccusions
|
|
about optimizing. Some clever people, wich skills and competence I trust,
|
|
claims - for CPU's manufactured last ~15 years size of code is crucial
|
|
for speed. (Better utilize CPU cache).
|
|
So I wrote some 'movsd' mnemonics instead 'mov [edi],sth'; 'loop' instead
|
|
'dec ecx,jnz sth'. Moreover I come back to init some local varibles
|
|
by 'push' (flat_cat.inc). I took effort to change divisions to
|
|
multiplications two_tex.inc (works ok in fpu only Ext = NON mode and
|
|
of course in Ext = SSE3 mode), grd_tex.inc (single line not parallel
|
|
muls, whole drawing routine 4 divs instead 27 divisions),
|
|
bump_tex.inc - 3 divs in SSE2 mode.s See sources for details.
|
|
4. Editor button allows now editing by vertex all above 65535 vert objects.

View3ds 0.075 - XII 2021
|
|
1. Cusom rotate using keys and mouse scroll support by Leency.
|
|
----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.074 - IX 2021
|
|
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).
|
|
----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.073 - may 2021
|
|
1. I introduced procedure for searching nonredundand edges.
|
|
2. Writing some info about object: vertices, triangles unique edges
|
|
count.
|
|
-----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.072 - march 2021
|
|
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.
|
|
-----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.071 - VIII 2020
|
|
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.
|
|
-----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.070 - VII 2020
|
|
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)
|
|
-----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.069 - May 2020
|
|
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).
|
|
-----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.068 - XI 2016
|
|
1. Editing option - new 'editor' button.
|
|
2. For now I disable perspective correction, to make implemtation
|
|
of editing option easier.
|
|
-----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.067 - XI 2016
|
|
1. Sizable app window.
|
|
-----------------------------------------------------------------------------------
|
|
|
|

|
|
1. App window size according to current screen resolution.
|
|
2. New emboss procedure.
|
|
-----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.065 - Feb 2015

1. Postprocessing effect - wave. Ability to change amplitude and frequency.
|
|
-----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.062 - VII 2012.
|
|
1. Counter fix by Mario.
|
|
2. New drawing model - smooth shaded lines (edges only view) by me.
|
|
-----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.061 - Nov 2011.
|
|
1. Two new buttons to increase and decrease brightness.
|
|
-----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.060 - Aug 2011.
|
|
1. Header fix by Leency.
|
|
2. SSE2 optimizations by me. (Most visable in BUMP_TEX mode.)
|
|
-----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.059 - June 2011.
|
|
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.
|
|
-----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.058 - June 2011.
|
|
1. Blur function optimization on SSE and SSE2 (buttons 'blur' and 'fire').
|
|
-----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.057 - April 2011.
|
|
1. By opening file bigger then ~18 KB, and choosing env mode program terminate.
|
|
I remove this bug
|
|
-----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.056 - February 2011.
|
|
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.
|
|
-----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.055 - January 2011.
|
|
1. SSE optimizations (file BUMP_TEX.INC).
|
|
2. Compiles correctly in newest FASM.
|
|
-----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.054 - December 2009 (Updated January 2010).
|
|
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).
|
|
-----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.053 - (?) 2009
|
|
1. Optimizations.
|
|
-----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.052 - November 2007.
|
|
1. Memory for file is allocated dynamically.
|
|
2. Optimizations.
|
|
Note: compiling correct only for KolibriOS.
|
|
-----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.051 - October 2007.
|
|
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.
|
|
-----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.05 - (?) 2007
|
|
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.
|
|
-----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.04 - March 2007.
|
|
1. New shading model: bump + texture. Only version with z coordinate
|
|
interpolation.
|
|
2. SSE optimizations ( files: two_tex.inc and bump_tex.inc )
|
|
-----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.03 - March 2007.
|
|
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 ).
|
|
-----------------------------------------------------------------------------------
|
|
|
|
View3ds 0.02 - December 2006.
|
|
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?)
|
|
|
|
There is really much work to do and I see disorder in app code.
|
|
Greetings for all, especially Madis Kalme for .3ds files support and good vibrations. ;)
|
|
Merry Christmas and happy new year.
|
|

App View3ds ver 0.01 - November 2006.
|
|
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.
|
|
-----------------------------------------------------------------------------------
|
|
|
|
App "View3ds" - it's very early, still unfinished version but I want show you it.
|
|
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. |
