Hey Brad,
I wondered if using math directly would be faster than working with XSIMath
objects, so I tried. You probably knew this, but to get a distance between
two 3D vectors the formula is quite easy:
* d = √ (Ax-Bx)2 + (Ay-By)2 + (Az-Bz)2
*
where A and B are two vectors to measure from.
sweet, i didn't know that either and was questioning it when reading your
code.

I knew the math, but for some reason assumed that compiled Math functions
would run faster than Python. That'll teach me. [?] Actually, thinking about
it now, anything that has to repeated call the COM
def find_closest_point(obj, pos):
x, y, z = pos
points = obj.ActivePrimitive.Geometry.
Points
count = points.Count
points = points.PositionArray
xx, yy, zz = points
delta = [((x-xx[i])**2 + (y-yy[i])**2 + (z-zz[i])**2) for i in
xrange(count)]
return
Can you use GetClosestVertex()?

I'm not finding that anywhere in the docs, is that available for Point Cloud
Geometry?

I was going by the following quote from the docs:
Note: Point locators are currently only supported by
NurbsSurfaceMeshfile:mill3d/server/apps/SOFTIMAGE/docs/softimage2012/en_us/sdkguide/si_om/NurbsSurfaceMesh.htmland
Nah, it was raising errors when I tried it before starting this thread, and
it still is now [?]:
# ERROR : 2028 - Traceback (most recent call last):
# File Script Block , line 2, in module
# obj.ActivePrimitive.Geometry.GetClosestLocations([0, 0, 0])
# File COMObject unknown, line 2, in
Care to share a sample snippet? Maybe there are even faster ways to
approach it.

All things considered, it's not too horrible simply looping through every
position from the Geometry.Points.PositionArray, and
10 matches
