How to DEFORM to sphere ?

It is not inflate, AFIAK.

I want to take micheus heightmap of a volcano or TWO ... and "bend" each on until the bottom of it would rest nice in a sphere. I think one input ... the arc bend for the radius of it after bending would be nice.

Anyone ?

I tried bending 45 with one rod, and then 45 on a mutually perpendicular rod ... but I don't like that result.

I already heard about this before - it has exactly two years (here).

Well, it was not done exactly for this purpose, but I think you could use Stamp mode I had implemented for Alpha Brush option of Sculpt's Optigon plugin:

You can find it on my Google drive: W.I.P/Alpha Brush

I bet you have not heard of THIS ... This is what I was asking about ...

Not released yet.

It uses code like :

R2 is radius of destination sphere.
R1 is radius from Y axis to point for which DY is calculated.
DY = math:sqrt( R2^R2 - (R1^R1)

---

Stamp mode is very cool, nevertheless. Thanks.

Yeah, I saw. I just haven't read that "to" in the subject, sorry.

Getting a bit off topic ... since I answer my own question ... and you answered it also ...

I was looking at maybe creating a RAW-TRIANGLE dense mesh at RUN-TIME (maybe in draw plugin routine),
and I continue to think that you could "ASSUME" a spherical MAPPING of the input image ... and then just apply it to points on a "geodome" and get great asteroids maker from your height-map surface plugin.

Geo-Dome looks to maybe have some basis for quickly making a sphere that would be STAMPED by a spherical projection image.

It it already works .. stamping an entire SPHERE at one time ... then appologies for being ignorant. I only have so much time.

My plan to to make a few more "WORLDS" like mystery science theatre 3000 style ... soon.
