4 | Whats new? |
| 5 | 1. Detecting manifold chunks procedure based on kind of sorted pivot |
5 | 1. More divs elimination comparing to ver 0.076, - grd_cat.inc file. |
| 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 |
6 | 2. Some 3ds object I have, reads with invalid normals - fixed. |
| 10 | in few seconds on i5 2cond gen. Earlier such objects calculating was |
7 | 3. Invalid submit edition bug - fixed. Smaller size of adjcent proc. |
| 11 | rather above time limits. |
- | |
| 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). |
- | |
| 16 | So I wrote some 'movsd' mnemonics instead 'mov [edi],sth'; 'loop' instead |
- | |
| 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 |
- | |
| 19 | multiplications two_tex.inc (works ok in fpu only Ext = NON mode and |
- | |
| 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. |
