setNumWrap Method
Set the number of vertices replicated in visitor arrays (both data and index arrays).
- 0,1,2 are the most common as numWrap.
- Example: suppose
[6,7,8]
is the pointIndex array representing a triangle. First edge would be6,7
. Second edge is7,8
. Third edge is8,6
. To access6
for the third edge, we have to go back to the start of array. Therefore, it is useful to store6
at the end of pointIndex array, i.e.,[6,7,8,6]
meaningnumWrap = 1
. - Continuing this example,
numWrap = 2
(i.e.,[6,7,8,6,7]
) is useful when each vertex visit requires the next two points, e.g., to form two adjacent vectors for a cross product.
