3D extrusion from sphere


Recommended Posts

Great tutorial @pdnnoob, thank you.

I had the idea, when I first read this tutorial, to use Point Blur instead of Zoom Blur and I wanted to try and see if it works. I was reminded of this by the current planet competition.


In the image below, the continents are extruded using Zoom Blur, as per the tutorial instructions. The ball is intruded, using Point Blur.



Using Point Blur does away with the need to adjust/enlarge the "surface"/top layer (that can be hit and miss).
