Spliting polygon from BSP FAQ
Author
well my question is simple....
I was reading the SplitPolygon function in the BSP FAQ but i didn''t understand one line! this:
real sect = - part->Classify_Point(ptA) / (part->Normal() | v);
what is the "|" symbol in the end of this line?
thank you!!
edit ignore this:
it's a bitwise OR
A||B will return true if A or B are non-zero
A|B will return the combined bits.
If

If
A = 1001001 andB = 0001101 thenA|B =1001101 [edited by - petewood on March 19, 2003 8:58:07 AM]
It's not going to be the bitwise operator in this case, since it's operating on a vector -- instead, it's an overloaded mathematical operator. Dot product, maybe?
EDIT: Checked out the FAQ and saw this:

Guys!!! Lets get serious!!!!You think that if a had the vector class definition i would ask you?????
I dont have it!!!
BSP FAQ dont have it!!!
thats why i am asking you!!!

Why are you completely ignoring the information I posted several hours ago?
Seriously. The information you needed was in the very FAQ you were reading, yet you didn''t find it. Don''t go nuts.
