Video Tutorial: Creating a DNA Double-Helix - LW - Scifi-Meshes.com

I just added one more subpatch video. This one shows how to create DNA double helix strands. It works for subd models and high poly models too.

Quote:

Modeling a DNA double-helix with subdivision surface / subpatch modeling in Lightwave 3d - In this video tutorial, we cover the creation of a DNA double-helix strand by using the strength of the lathe tool and the power of some math and the clone operation. The final model is a clean model that is subpatch ready. The same technique can be applied to a high-res poly model as well if needed.

In the video the formula for the number of clones is: (number of revolutions*number of bars per revolution). The formula for the Y offset is: (height of the helix/number of revolutions/clones per revolution). The formula for the heading rotation is: (360/number of clones per revolution). The number of clones per revolution is an arbitrary number you pick depending on how close you want them together. I chose 10 in this video.

This new video is at the bottom of the list. Enjoy!!

^Seconded!

Very worthwile additions to the library of resources anyone starting out with Lightwave should be building up.
