I have a grid of intensity values which I am displaying using
Color/ColorMap:
8.0 + 0.0 0.0 0.0 0.0 0.0
|
7.5 + 0.0 1.0 0.0 1.0 1.0
|
7.0 + 1.0 2.0 1.0 2.0 1.0
| |
y 6.5 + 0.0 1.0 2.0 2.0 2.0
| |
6.0 + 1.0 2.0 2.0 3.0 2.0
|
5.5 + 2.0 3.0 3.0 4.0 3.0
|
5.0 + 2.0 3.0 4.0 5.0 4.0
|
+---+-------+-------+-------+-------+
1.0 1.25 1.5 1.75 2.0
- x -
As you can see, the x positions range linearly from 1.0 to 2.0. The y
positions range linearly from 5.0 to 8.0.
When I use a Pick, I can extract the "closest vertex" which would give
me an x/y position coordinate (e.g., {1.25 6.5}).
How do I translate this into a zero-based index into each of the x/y
positions (e.g., {1.0 5.0} -> {0 0} or {1.25 6.5} -> {1 3})?
Any help is greatly appreciated.
