Title: Radial Array
Post by: 3DToons on October 02, 2012, 02:59:11 pm

I was wondering if you could add rotational values to the "Duplicate Instance" Array dialog please? Currently I only see options for translation and scale. Am I missing something?

Cheers,

Hello,

I was having a quick look at this implementation. When using the option "Ellipse" (or Oval), should the instances not be (by default) equally spaced and orientated to path?

Snap shot from VNIL showing (top) an "Ellipse" from "Instance > Radial > Ellipse". The instances have not been equally spaced and do not have orientation to underlying path. Below that, shows the result of "Instance > Spline" which is how I would of expected "Radial > Ellipse" to look like.

It looks like the orientation matches the tangents of a circle. The translation looks like it is accelerated towards the apex, which I would expect, if the translation is still being based on a circle, which is then scaled.
If you set the number of instances high enough, the option "oval" creates something like this: http://en.wikipedia.org/wiki/Lemniscate_of_Bernoulli
Is this intentional?

Improved.

I implemented the 'Oval' style by mistak because I forgot the Ellipse equation. Since it's been done and can be usefull anyhow, I just keep it, no waste.

Thanks for testing this guys! I haven't had the chance yet... and thanks for adding an ellipse IStonia! What a bonus!
