{Challenge} Point Sort
« on: February 12, 2011, 04:09:53 PM »
I do not know if this is a good one but I threw together code real quick and created 2 drawings

1. 20,000 random points with x,y,z (-100 to 100, -100 to 100, 0)

2. 20,000 random points with x,y,z (-100 to 100, -100 to 100, -100 to 100)


Any ideas maybe sort by closest to orgin in QI , then closest to orgin QII, then QIII, then QIV then repeat.

I do not know. I sounded like a good idea until i started typing all this.

2 drawings attached I saved them down to 2004

What are QI to QIV in reference to? Otherwise point sorting is relatively easy.

I imagine they'd be geomertic quadrants Paul.

0-90, 90-180 etc

Quadrant 1 , Quadrant 2 , Quadrant 3 .........

Otherwise point sorting is relatively easy.

Yeah I was trying to come up with a idea like sorting points by largest difference between a Points X & Y value, but it still boils down to essentially they same thing.
I was trying to spark an idea.

Code: [Select]
pts.Sort((p1, p2) => p1.DistanceTo(Point3d.Origin).CompareTo(p2.DistanceTo(Point3d.Origin)));
