Student Showcase - Animation with Realflow by Kalim Momen, Georgia Nichols and James Hatton

Recently our first year animation students have been experimenting with fluid dymanics, using Realflow to produce animation effects. The results have been excellent, all of which goes to show that technology is rapidly changing what we think of animation, and the way that the medium can be accessed by students. Traditional key-frame animation is just one way to make things come to life. Dynamics and simulation software should be as much a part of an animator's toolkit as motion capture or motion graphics - all part of the way we breathe life into our work.

What is Realflow anyway? According to Wikipedia: "RealFlow is a fluid and dynamics simulator for the 3D industry, created by Madrid-based Next Limit Technologies. Currently at version 2013, the stand-alone application can be used to simulate fluids, water surfaces, fluid-solid interactions, rigid bodies, soft bodies and meshes. Victor Gonzalez, Ignacio Vargas and Angel Tena were awarded a 2007 Technical Achievement Award from the Academy of Motion Picture Arts and Sciences for the creation of the RealFlow software application".

Below are two examples of our students' work which turned out especially well. The brief was to create an advertisement for a real product - showing how dynamics can be used in the commercial world. First up is an advert for Lush cosmetics by Kalim Momen:




Below is a commercial for for Powerade by James Hatton:




Finally, a commercial for hair colour by Georgia Nichols.

Hair Simulation in Maya 2014

Rapunzel - great hair!

One of the best new features of Autodesk Maya 2014 is a big step forward in its hair simulation capabilities. The new tool is called XGen, and it comes free with Maya 2014. It was developed by Disney/Pixar and was used on their recent film Rapunzel, to generate the heroine's gorgeous, bouncing tresses.

At the BlueGFX Expo in London last month, Autodesk demonstrated their new hair simulation tool, giving us a step-by-step tutorial in how to go about creating great hair effects in Maya with this new instancing system. So how exactly does it work?

XGen is found under the Dynamics tab in Autodesk Maya. You go to Create/XGen/description, and give it a project name. Pick groomable splines/create to create your new hair map.  You can use the Density slider to add to or reduce the density of the follicles.

Using the brush tool you can paint the hairs to make them bigger or smaller. You can pose them too, grooming the hair to make it follow the contours of the body, growing out in different directions, just like real hair.

On a facial rig, you can add stubble, a moustache, a beard. You will generally do this on a separate mesh. Underneath the hair mesh will be the original mesh, which will have its own skin shader.

You can also use XGen to create other effects, such as long grass waving the wind. You can use the same system to propagate trees in a landscape, or grass over a field, or roof tiles on a roof.

So, next time you're working on a character rig, have a go at XGen and see what you can create.
