What's new?
 5 
1. Detecting manifold chunks procedure based on kind of sorted pivot
- 
 
 6 
    table. Chunks are counted and this number displayed.
- 
 
 7 
2. New calculating normal vectors proc that use some data produced
- 
 
 8 
    by new chunks routine. Now big object loading is fast. I load object that
- 
 
 9 
    contains ~500000 vertices,  ~700000 faces and  ~2000 0000 unique edges
5 
1. Fixed emboss bug in grd lines displaying model.
 10 
    in few seconds on i5 2cond gen. Earlier such objects calculating was
- 
 
 11 
    rather above time limits.
6 
2. Grd line exceedes screen problem fix.
 12 
3. On http://board.flatassembler.net occasionaly there are some disccusions
- 
 
 13 
    about optimizing. Some clever people, wich skills and competence I trust,
- 
 
 14 
    claims - for CPU's manufactured last  ~15 years size of code is crucial
- 
 
 15 
    for speed. (Better utilize CPU cache).

3. New rendering model - ray casted shadows and appropiate button to
 16 
    So I wrote some 'movsd' mnemonics instead  'mov [edi],sth'; 'loop' instead
8 
   set 'on' this option. Note that is non real time model, especially when
 17 
    'dec ecx,jnz sth'. Moreover I come back to init some local varibles
- 
 
 18 
    by 'push' (flat_cat.inc). I took effort to change divisions to
9 
   complex object is computed. I took effort to introduce accelerating
 19 
    multiplications  two_tex.inc  (works ok in fpu only Ext = NON mode and
10 
   structure - AABB (Axis Aligned Bounding Boxes).. but it is disabled
20 
    of course in Ext = SSE3 mode),  grd_tex.inc (single line not parallel
- 
 
 21 
    muls, whole drawing routine  4 divs instead 27 divisions),
- 
 
 22 
    bump_tex.inc - 3 divs in SSE2 mode.s  See sources for details.
- 
 
 23 
4. Editor button allows now editing by vertex all above 65535 vert objects.

   for now - seems to work incorrect(slow).
