viz intersect object point

Hi all,

I am trying to return a list of 100 intersections based on 100 points that stretch across the centre of the screen.

However, when I print the points out, I get a list of values which are not right. The Y coordinate seems correct but the X and Z coordinates usually float between 0 and 1. I know this isn't correct because I can load the model up in the explorer and see that the general area where I am returning these points are nowhere near these tiny values.

Here is the code
Code:
	def _calculateDropPositions2(self):
		screenUnitX = 0
		intersections = []
		self.worldPositions = []
		
		for index in range(100):
			screenUnitX += 0.01
			obj = viz.pick(pos = [screenUnitX, 0.5], info = True)
			if(obj.valid):
				intersections.append(obj.point)
		
		for i in intersections:
			print i
And here is the output.

Code:

I am using the <window>.frustum() function to set my viewing frustum. Could this be affecting it? Any thoughts on this?

I didn't notice anything that looked off with the code you posted. Can you post a simple example that reproduces the issue?
