Naughty Dog Muscle Recreation (Proof Of Concept)
So this is my attempt to recreate the effects of a tool made by Judd Simantov at Naughty Dog. It is a simply distance based muscle simulation. How it works There are two pairs of locators. They drive the CV position of two linear curves. The are lofted to create a nurbs surface (I do this with a node but don't actually have a shape node). The point on the surface (that matches the position of the midpoints of the two curves) has it's position and normal vector queried by a po
Local Space Parent Constraint
So setting up individual local rig controls using direct connections is fairly easy. But it does require a buffer group for each object on the local rig (two groups if the controls are not oriented to the world). And once you started having hierarchies of controls driving hierarchies of joints on the local rig, keeping the orientations straight can become a nightmare. If only creating a local rig could be as easy as using parent constraints on the global without the need for
Making Local Motion-Paths and Rivets
So in this tutorial I show off how to use matrices to make motion paths and rivets and follicles work in local space rather than worldspace by using some matrix math. If you aren't familiar with matrices this post has a list of resources: https://www.jonah-reinhart.com/single-post/2018/02/14/Up-Vector-Trick-Part-2-Maya-Matrices
Ball Rolling On Surface - Rhino Palooza Part 3
Just a quick (but in my opinion visually impressive) update to the rolling ball, contact with a ground plane. The ground contact is actually achieved fairly easily. instead of using the position of the control to drive the position of the ball directly, we put it through a node network. We find the closest point on surface to the controls position We get the normal vector at that point. We add the normal vector to the position (we would need to scale the normal if the ball ha
Procedural Ball Rolling - Rhino Palooza Part 2
So here it is! A procedurally animated ball. As before the only keyframe animation is translations. The techniques I used are pretty much the same as the ones in the Disney Paper but they still need to be encapsulated into a nice package before they could really be applied in a useful way. In Part 3 I plan to implement ground plane contact using a nurbs surface and matrices. and maybe set the system up to be more nicely contained in one tranform node. Seems like a lot of stuf
