What new was implemented?:
+ 32 bit indexes of vertices and many changes according this.
+ Multi cores calculating normal vectors according to both triangles and vertices.
+ More accurrate joining ( 'M' key) and editing (scale, translate) new mesh.
+ Better remove redundant vertices proc.
+ Option to merging triangles.
+ New triangulation procedure.
- Disabled creating and editing solid rotated bezier curve and short pipes
option and buttons according to this edition.


Knowed bugs, not yet removed:
- Triangulation of 'Cordis Christi' object not correct.
- In edit edges option apear some not needed additional edit bars.
- No ability to edit long pipe (but renedering process OK).
- No ability to save 3ds file of object that contains more than 65535 vertices
or triangles. ( But saving to asc file - OK ).

What new was implemented?:
+ Several messages about current processed function appear on top bar.
+ New uniqe detection of edges procedure.
+ Teslation of chosen area, not only on whole object. I returned back to
prevoious avialable option but now is on 32 bit indexes and multithreaded.
+ Dispalying information about object table: edges, faces, vertices count.
+ Bit improved (?) merging triangles option.

Bugs, that still present:
- Triangulation of 'Cordis Christi' object not correct.
Object degenerated - it need rewrite.
- In edit edges option apear some not needed additional edit bars.
- No ability to edit long pipe (but renedering process OK).
- Saving only first 65535 vertices and triangles to 3ds file.( But saving to asc file - OK ).
- Many others

1. Ability to edit bezier patches. To edit patches press E key or 'b. derives'
button - draw bezier derives, before that select bezier object you want to
edit - press B key or 'bezier sr.' button times you need, stop animation
(press F11 key or button 'run/stop'). Now edit by moving yellow bars
with pressed left mouse button, when left button is released new position
of bar and bezier derive is accepted. Bezier patches are recalculated
permanently. To achive previous geometry restart app.
2. I took attempt to removing inside faces and vertices - it means faces that
from all points of view are hidden. It process (near) correctly when
triangles are relative not so small. Try to use selecting 'Rm ins fac' button.
3. I try with new rendering model - fur processing. In this model clipping
was not maked - if object excedess screen app will hang.
4. I remove some bugs. (But some still are present).

What's new in version 26?
1. Fixed edition of bezier patches.
2. I made remove cracks feature. -> When only part of object is
teslated (triangulized), on borders araises slits (cracks), that
are caused by wrong declaration of triangles in triangles net.
Now app perform prevention of such artifact. But another artifact
will occur - crack prevention in my implementation would caused
long, thin triangles, especially when mass teslation of chosen area is
performed. That can be avoid by "step by step" shrinking teslation,
area, when proces is launched. Also I could implement correction of
valence balace in future. I include sample object teslated with new
features and aplied displacement in app package. Note: chosing
teslate area - under 'set t. area' button.
3. Backface culling option and apropiate button in menu.
4. Clipping on fur rendering model and dividing it into threads, still
need polish.

My attempts:
I took attempt, but unfortunetly not succesful:
1. Smoothing inside edges, that are usually jagged
after removing inside faces.
2. Smoothing long, multi segment Bezier pipes.
When curve turn onto Z axis, rendered pipe also turns,
around itself, which looks annoying.

What's new in version 27?
1. Detecting collided edges button - detect and count edges that
intersect other triangles. Such edges are marked green on
rendered image.
2. Mark separate chunks button. Mark with unique color edge of
triangles that are adjacent one to another - it mean from one
of such triangle is posible "to go" along its edges (and vertices)
to other triangle from separate chunk. Chunks are counted.
3. Smooth inside edges button. When removing inside faces is
performed, some inside edges from separate chunk can be
jagged. This option fix such situation. Some small margin are
leaved. Option need correct declared normal vectors sense in
each chunk.
4. Scroll bar in buttons section of screen. Press left mouse button
when cursor is on scroll bar and move mouse with pressed left
button - buttons section will be scrolled.

What's new in version 28?
1. 'Clip faces' button - faces that are outside teslate rectangle,
are clipped.
2. 'Invert chn' button - invert sense of normal vectors in whole
separate chunk. First 'Srch chunk' must be set "on".
3. 'Crop front' button - only front of object is leaved. Some small
margin (several degrees) is leaved.
4. Rotate posibility of freshly joined mesh ('M' key) under
'NextM edit' button. Such option is achived when red bar on
"edit area" is moved (using left button of mouse).
5. I multithreaded removing inside faces option.
6. Faster detecting collided edges algo (Moeller-Trumbore).
7. Deleting separate chunk posibility.
8. New rendering model - ray casted shadows, it's not real time
model, after rendering one frame app stops, to run it again
switch rendering (drawing) model by pressing 'dr. model'
button.
