Hi all,
I have loaded an object *.ac in my programm with
char Data_Path[128];
int Num_Triangles;
aircraft = new ssgTransform ;
sprintf(Data_Path,"..\\Data\\");
ssgModelPath (Data_Path) ;
ssgTexturePath (Data_Path) ;
ssgEntity *aircraft_obj = ssgLoadAC ("body.ac") ;
aircraft -> addKid ( aircraft_obj ) ;
ssgFlatten ( aircraft_obj ) ;
ssgStripify ( aircraft ) ;
For further manipulation I needs information about the triangles and
vertices of the aircraft_obj. I will implement shadowing after the NEHE
Tutorial Lesson 28.
What commands from plib I have to use ?
With regards
Michael

The good point is that one interface does all cases: - ssgVtxArray and ssgVtxTable. - triangles, quads, n sided polygons. - ignores points and lines. So, with very little code you can get all faces as triangles. You just have to walk the scene graph. See for example, in PPE, in ppeWalkScene.cxx the function: void ppeBuilder::countGeometry( ssgEntity *e ) >With regards > >Michael Bye bye, Wolfram. |

Hi Wolfram, I have downloaded the source-tar-file as tar.gz but could not extract it with winzip. Do you can send me the ppeWalkScene.cxx by e-mail ?

That's probably because you downloaded it with Internet Explorer which is
buggy.
If you did use IE, what happened is that *it* automagically uncompressed
the GZIP but didn't rename it without the '.gz' extension;
If you rename <whatever>.tar.gz to <whatever>.tar and then use Winzip
to un-tar it, you'll be fine.
Alternatively, download it with Netscape - which works.

Hi Steve, I ahve tried it with Netscape. But also no success.

Actaully I've seen some Irix versions of Netscape try the decompression trick as well (but I think the machine's netscape might had been setup to pipe the file through gzip and then to disk in the mime-type settings). Anyway, what version of Winzip are you using?
