$KarmaXPU Quickstart Pt.4: Excursion - Visualizing Lipid Membranes Download Scene File: https://www.entagma.com/downloads/membrane_lipids_01.zip Notes: - Instead of using the pointVOP/quaternion method to rotate lipids, you could also use the scatter & align method described here: https://youtu.be/tCijuuNIRrs - Im recommending to stay away from refractive materials in rendering. This is due to the fact of this particular group of students having limited rendering resources. If however you have those resources, go wild! Mo had the pleasure of joining Dr. Jeroen Claus of http://www.phospho.co.uk, teaching a visualization workshop to students at university of Maastricht. The topics covered were protein and lipid membrane rendering in Houdini using KarmaXPU.
