Neural Networks and Animation

research and development

I’ve recently published, as an open source project, the code for feNeuralNet. This is a Fabric Engine extension for doing simulation of previously trained Neural Networks. Fabric Engine is a plataform for CG development that works standalone but is also integrated in many animation packages like 3ds Max, Maya, Softimage, and Modo. Yes, that means you can now play with neural nets in any of those packages.
If you are wondering what good is having neural networks in an animation package, so am I! On a more serious note, machine learning is enabling people in many fields to come up with computational solutions for problems that were previously very hard to solve… I am curious to see what real applications can emerge in animation and vfx pipelines in the next few years.

Processing moCap data for Machine Learning with Fabric Engine

research and development, training

In this three part video series I show the challenges in pre-processing motion capture data for machine learning and how one can go about this task. I use Fabric Engine as a development tool for this task. If you find this video helpful or if you have further comments or questions on this topic, please, leave a reply bellow.

Non-Humanoid Creature Performance from Human Acting

publications, research and development

In this work we propose a framework for using human acting as input for the animation of non-humanoid creatures; captured motion is classified using machine learning techniques, and a combination of preexisting clips and motion retargeting are used to synthetize new motions. This should lead to a broader use of motion capture.

This work was presented as a poster at SIGGRAPH 2016. Click here for the full publication.

Motion Tools

research and development

Motion Tools is a small collection of tools that aims to aid Motion Graphic work being created inside Softimage. It does so by providing many ICE compounds and partially abstracting the ICEtree construction processes. It eases the creation, procedural animation and simulation of many many objects or chunks of geometry.

motion tools v0.4

research and development

Motion Tools is a small collection of tools that aims to aid Motion Graphic work being created inside Softimage. In this latest release the capability of controling polygons and polygon islands with particles was added. Therefore enabling one to control this elements with regular ICE nodes, or Motion Tools’ compounds.
Some high priority bugs and workflow enhancements were tackled, although, due to time constraints these improvements were not akin to the initial intention. I hope this still may prove useful to some.

Constraint along strand

research and development

In the middle of production I was face’d with something I had not done yet. We had to constraint a bunch of strands to the tip of another strand. As in the time we did not have Syflex for ICE we decided to use ICE’s own strand framework. Good for us it was not hard arranging a bunch of nodes in order to get this constraint going.
All I had to do to share it online was to make it a little more flexible and scale friendly. Here it is hope you like it.
