Hi,
In the last couple of days I have implemented the b-rep conversion function for
superell. When n <= 2 and e <= 2, it produces the exact same result as we want,
but when one of them is greater then two, they are slightly different. (This
may result from the non-smooth surface of the super ellipsoid when n or e > 2,
as the NURBS surfaces always tend to be smooth.)
And I also looked into other primitives, and have some questions. As for the
'grip' primitive, is it something like half? I found it does not show in
raytracing. So, in what situation do we usually use this primitive? And for
what purpose? Besides, I'm also quite confused with the 'cline' primitive. Its
detailed name is FASTGEN4 CLINE, and FASTGEN4 is another data format. After I
raytrace this primitive in different views, I still cannot imagine what its
shape should be. So, could someone please figure it out?
At this time, most primitives already have implemented b-rep conversion
functions and the functions works quite well, and I will still test the results
and modify the code if there's some problems. And, what else can I do besides
the testing and modifying? Could someone please give me some suggestions?
Cheers!
Wu
