View Full Version : Perimeter point-count grid tool?

Does there exist a tool that allows the user to make a rectangular grid of varying dimensions that would try to conform to a specific perimeter point count?

Or at least count the perimeter points for the user so that s/he could try various arrangements?

I don't understand what you are asking. Can't you use the box tool's segment settings to put the number of points you want on the box perimeter?

Sure, but it's very slow and horribly tedious.

Now, you can just use this:

Too specific.

x = a * 2 + b * 2
x = 2 * ( a + b )
x / 2 = a + b
a = x / 2 - b

f.e.
x = 28
a = 28 / 2 - b = 14 - b

b= 4
a = 28 / 2 - 4 = 14 - 4 = 10

You mean "the chart is too limited"?

x = a * 2 + b * 2
x = 2 * ( a + b )
x / 2 = a + b
a = x / 2 - b

f.e.
x = 28
a = 28 / 2 - b = 14 - b

b= 4
a = 28 / 2 - 4 = 14 - 4 = 10
Perhaps I should append Sensei's algorithm to the bottom of the chart for users who have to match >40 points. Should I?

For up to 40, I think the chart's faster.

Tool would be too specific. You're the only one on the planet who is interested in it ;)

:dance: Quite likely. But don't other modelers need a way to fill in areas like illustrated, or am i just missing the incredibly obvious way to do it?

But mostly, I figured somebody might have already done it.

Like using splines? ;)

Bah: even w/Larry's Spline DVD, it seemed like too much work, ESP for a flat surface.

Now, something like a boat hull or a complicated ceramic or a face, sure. But a FLAT area? And I'd still have to do the math, no?

It's simpler to do it, than describe it in English....

I could reduce this to 30 seconds..

If you don't want all edges going to central point, make two points on the left spline like here:

That's an excellent reason to buy EasySpline.
