## 3 questions...from my first experience using this calculator

1

when I enter

x = pi,

y = pi

y = -pi

it returns the expected planes

when I also enter

z = pi

x = -pi

z = -pi

these 3 planes seem to be missing...

2

also, can one control the size of the diameter for single points...say even as diameter sqrt 2

3

what import formats are allowed...will it accept an .off file ?

## after seeing two instruction videos...

I just found the video instruction.

So, the only question that remains from those three...

1 can I input .off files...and what file types/formats...can I input ?

Now please, another question

2 Given 3 coordinate points...can I get it to make a triangle ?

and a third , s.v.p.

3 given a bunch of points...could it construct a convex hull from them ?

Hi Steve, here are the answers to your three questions:

If you have more questions please do not hesitate to post them here.

You cannot import .off files. The only file format that you can import is .csv which can would consist of a columns for x, y and z values. You can use Ms Excel for that and save it as .csvsteve waterman wrote:1) can I input .off files...and what file types/formats...can I input ?

Yes, but the software needs a minimum of 4 coordinates so to make a triangle you would have 4 coordinates, with 2 coordinates having same value.steve waterman wrote:2) Given 3 coordinate points...can I get it to make a triangle ?

No we did not add this feature because not many users need to draw convex hull using our software. We can add this feature for you but it would be a custom project with a cost.steve waterman wrote:3) given a bunch of points...could it construct a convex hull from them ?

## figured out myself...missing planes

Okay...figured out why those planes did not show...one x value...not two different values...as per pi and -pi.

Hey I am still a newbie here ...learning curve thingie, eh.
