8232	leency	1
8719	leency	2	1. New displaying model - texturing with bilinear filtering and transparency
		3	simultanusly. Note that filtering is done only inside polygon. To better
		4	quality of image there is a need to use floats coordinates of texture to pass
		5	as arguments to single triangle rendering proc.
		6	2. Optimizations.
		7	3. SSE3 version runs correct on SSE2 cpus, but real phong, glass and
		8	transparented texturing with filtering rendering models are disabled.
		9	-----------------------------------------------------------------------------------

8666	dunkaist	12	1. New displaying model - glass - it's two pass rendering. First pass calculates
		13	Z position of all front pixels, second render image with adding reflective
		14	component of light only for front pixels. Transparent effect by adding with saturation.
		15	2. I removed bug with performing generation object after choosing 'emboss' option.
		16	-----------------------------------------------------------------------------------
		17
		18
8232	leency	19	1. Some keys support by Leency.
		20	2. New displaying model - real Phong - real not fake normal vector interpolation,
		21	normalising it and calculating dot product (one for each light).
		22	It requires SSE3. (by me, Maciej Guba)
		23	-----------------------------------------------------------------------------------
		24
		25
8047	leency	26	1. KPacked files support by Leency.
		27	2. 32bit vertices indexes and ability to load whole RAM limited objects.
		28	(Above 65535 vertices and triangles), (by me).
		29	3. I switch off painters algotithm mode (depth sorting). In app impelementetion it has
		30	limited vertices count and produce less quality image than Z buffer Catmull algo.
		31	In addition this switch off reduces app size, (by me).
		32	-----------------------------------------------------------------------------------
		33
		34
7280	leency	35	1. Editing option - new 'editor' button.
		36	2. For now I disable perspective correction, to make implemtation
8014	leency	37	of editing option easier.
		38	-----------------------------------------------------------------------------------
7280	leency	39
		40
6769	IgorA	41	1. Sizable app window.
		42	-----------------------------------------------------------------------------------
		43
5486	leency	44
6769	IgorA	45	1. App window size according to current screen resolution.
6648	leency	46	2. New emboss procedure.
		47	-----------------------------------------------------------------------------------
		48
		49
6619	leency	50	1. Asc files support.
		51	-----------------------------------------------------------------------------------
		52
		53
5486	leency	54	1. Bug fixes.
3066	leency	55	-----------------------------------------------------------------------------------
		56
		57
		58	1. Postprocessing effect - wave. Ability to change amplitude and frequency.
		59	-----------------------------------------------------------------------------------
		60
		61
		62	1. Counter fix by Mario.
		63	2. New drawing model - smooth shaded lines (edges only view) by me.
		64	-----------------------------------------------------------------------------------
		65
		66
2736	leency	67	1. Two new buttons to increase and decrease brightness.
		68	-----------------------------------------------------------------------------------
		69
		70
2193	leency	71	1. Header fix by Leency.
		72	2. SSE2 optimizations by me. (Most visable in BUMP_TEX mode.)
		73	-----------------------------------------------------------------------------------
2736	leency	74
2193	leency	75
1979	yogev_ezra	76	1. Bump and pararell two texture mapping functions optimizations.
		77	(files bump_cat.inc & two_tex.inc)
		78	On my P4 changes are rather non visable, but on dual core in KlbrInWin
		79	optimizations runs preety nice.
		80	-----------------------------------------------------------------------------------
		81
		82
		83	1. Blur function optimization on SSE and SSE2 (buttons 'blur' and 'fire').
6619	leency	84	-----------------------------------------------------------------------------------
1979	yogev_ezra	85
6619	leency	86
1931	yogev_ezra	87	1. By opening file bigger then ~18 KB, and choosing env mode program terminate.
		88	I remove this bug
		89	-----------------------------------------------------------------------------------
		90
		91
		92	1. MMX optimizations in 2tex mode (file two_tex.inc).
		93	2. Tiny SSE optimizations (file BUMP_CAT.INC).
		94	3. Bit (two instructions) improved random light generation procedure.
		95	-----------------------------------------------------------------------------------
		96
		97
1819	yogev_ezra	98	1. SSE optimizations (file BUMP_TEX.INC).
		99	2. Compiles correctly in newest FASM.
		100	-----------------------------------------------------------------------------------
		101
		102
		103	1. Skinned window by Leency.
		104	2. Optimizations.
		105	3. Re map texture, bumps option - allow spherical mapping around each axle (X,Y,Z).
		106	4. Problem with too small memory to generate object fixed. (Problem ocurred with
		107	house.3ds object and others objects contains less than 1000 faces and points).
		108	-----------------------------------------------------------------------------------
		109
		110
		111	1. Optimizations.
		112	-----------------------------------------------------------------------------------
		113
		114
		115	1. Memory for file is allocated dynamically.
		116	2. Optimizations.
		117	Note: compiling correct only for KolibriOS.
		118	-----------------------------------------------------------------------------------
		119
		120
		121	1. More smooth texture mapping in tex and txgr shading model and others based on
		122	tex3.inc, tex_cat.inc shading models.
		123	2. Predefined three, I hope, nice lights.
		124	-----------------------------------------------------------------------------------
		125
		126
		127	1. New shading model: cubic environment mapping with 1.5 kb light buffer.
		128	2. Bumps optionally according to texture. ( It gives so called texture with
		129	shifts in bumps + texture shading model. )
		130	3. Bumps depth button.
		131	-----------------------------------------------------------------------------------
		132
		133
		134	1. New shading model: bump + texture. Only version with z coordinate
		135	interpolation.
		136	2. SSE optimizations ( files: two_tex.inc and bump_tex.inc )
		137	-----------------------------------------------------------------------------------
		138
		139
		140	1. Two shading models: smooth + texture, spherical environment mapping + texture.
		141	Version only with z coordinate interpolation.
		142	2. Bit changed rotary. I took attempt in SSE instuctions. ( matrix multiplication )
		143	3. Color position depend drawing model instead spot light ( I hope,spot light come
8047	leency	144	back in future ).
1819	yogev_ezra	145	-----------------------------------------------------------------------------------
		146
		147
		148	1. New shading models - "spot" - spot light (only one, it's very CPU hungry model,
		149	and there is no easy way to implement buffer) with light attenuation (In my
		150	implmentation works not perfect); "dots" - app draws only points (with no culling).
		151	2. Some loseless operations "mirror": according to each axis, rotary 90 degrees.
		152	3. Postprocesing efects: Emboss (use blur to make edges more visable), fire ( be
		153	carefull during `fire + embos`parallel using).
		154	4. "Move" - Changes meaning of 'add vector' buttons:
		155	used "obj" move object, "camr" move camera (in this option use culling = 'off'
		156	I must make culling procedure bit advanced).
		157	5. Generate button. Few objects generating (with bad normals)
		158	6. Some optimizations on MMX.
		159	7. I took an attempt to memory managing functions, but it decreased speed (no aligned
		160	memory in Menuet functions?)
		161
		162
		163	Greetings for all, especially Madis Kalme for .3ds files support and good vibrations. ;)
		164	Merry Christmas and happy new year.
		165	-----------------------------------------------------------------------------------
		166
		167
		168	1. Object generating (for now only one). When no parameter specified or error occured
		169	during reading file from disk, app generate object. No teapot.3ds needed on ramdrive,
		170	but, if this file exist it would be read as default.
		171	2. Bug in read_from_file procedure fixed. (In May, when I made shading light vector
		172	depend, I demaged bit Madis' procedure.)
		173	3. Backface culling on/off option. (Some objects need culling off - they have mismatched
		174	normal vectors. Example: iron.3ds, sink.3ds, the generated one.)
		175	4. Random lights procedure.
		176	5. Spherical (instead old - planar ) bump, texture mapping.
		177	6. Bit improved menu.
		178	7. Blur.
		179	-----------------------------------------------------------------------------------
		180
		181
		182	Based on earlier demos.
		183	1. 3ds object import as a parameter ( for now only short names supported )
		184	I updated Kfar app - it can run view3ds with parameter. You must copy it on
		185	ramdrive. You could do such funny thing: Run updated Kfar in KolbrInWin,
		186	before them set in KolInWin.ini file path to ramdrive, where yo have "view3ds",
		187	choose 3ds file ... Emulator will run View3ds with selected file.
		188	If no parameter specified, app try open tpot.3ds from ramdrive. If tpot.3ds
		189	don't exist on rd, app hang.
		190	2. Many lights. Every light - unlinear model ( Phong illumination ). For now
		191	no light setting option.
		192	3. Light buffer for grd, flat model.
