We've made good progress in exploring dual-handed mesh manipulation for M4. While there are some caveats, the H3D system provides support for using various combinations of two phantoms on the same computer.

Most real-life examples of typical two-handed operations, such as painting easter eggs (or

Halloween time seemed like a good opportunity to present our project to the other members of our VR lab, so we held a (virtual) pumpkin carving contest. We used an active stereo projector and a Desktop phantom an invited everybody to carve, deform and paint a virtual pumpkin model. Here are a few

We've added a lot of new functionality to the mesh manipulator and put together a 3 min. movie to showcase them.

Shaders: Jon has integrated a couple of OpenGl Shaders - one provides smooth, per pixel lighting where the light source is slaved to the stylus direction. Another shader deals with

Although we have been referring to our earlier work internally as the geosculpt  project, I wanted to find a name for the project that better reflects the general nature of the project rather than its geoscience origins. It also needed to have a nice acronym! After some head scratching, we came up

It was something of (Geek)-Christmas in July here in the lab as several boxes full of techno goodies arrived today. Thanks to the generosity of Chevron and the efforts of Bill Kowalik, who used to be involved in haptics research at Chevron, we are now the proud owner of several more Desktop

Here's a video (MPEG-1, 22.3 Mb) of the results of a freshman honors project I mentored in Spring 2007. Ashley Polkinghorn and Amanda Newendorp, both new to sonification and to Python, put together an application that takes climate data from ~200 locations in the US and "plays" its average monthly

This is our first attempt to branch out into the area of art and potentially music. As we have been working with H3D on combining vision, touch and sound for scientific data wit seems natural to think about using this technology to create sounds from user input and maybe create a sort of virtual,

That's quite a mouthful, I know :) The setup is this: touching a surface mesh with the stylus-tip at a certain location allows us to calculate a value for this location, for example its elevation or a value stored in a texel at that location (texture lookup). Before we can sonify this value we

My student Mike and I have worked on a H3D demo to show how to deform a terrain mesh. This is a continuation of our earlier work on simply presenting geospatial data to a user via 3D vision, touch and sound - we now allow the user to play god and deform the terrain by pushing and pulling on the

We recently completed a study to determine the potential use of effects of a novel road planning systems. This system takes the idea of a traditional Geographic Information System (GIS) and adds touch and sound, making it into a multi-sensory GIS. For this Matt Newcomb and I teamed up with Reg

The idea is to deform the geometric model of  geological surface (for example the top of a sediment strata) so that it will fit to "hard data" from drill holes. Initially, the true geological surface is approximated by a perfectly flat and continuos mesh. We pretend that the actual position of the
