Data from MEMG project

We are providing all the data used for our paper Mesh Ensemble Motion Graphs in the hope that it will be useful for followup work and additionally to provide new data for testing animation compression algorithms.

If this data is useful, please cite us. (how?)

Details of the binary data format can be found here. If you have questions about the data, the viewer, or related topics, please contact Christopher Twigg.

Viewer

To facilitate the use of our data, we are providing a simple viewer application. We are also providing the source code which you can use as a base for your own reader.

Windows binaries are provided below. Since the source code is based on wxWidgets, it should be fully portable to other platforms with only a recompile. To use the viewer, simply extract the provided .zip file and run the motionViewer.exe application. You are required to first open a .obj file so that the viewer can extract mesh connectivity information. Next, you can open a motion file (extension .mot). To look at a different model, simply open the associated .obj file.

Camera controls are simple: left button rotates, middle button translates, and right button zooms. Please let us know if you have any problems running the application.

To build the viewer yourself, you will need to obtain Andrew Willmott's Vector Library. However, the version used for this project is slightly modified so that everything is in the vl namespace. Source code and binaries for this version of VL are provided below. We have provided both a Visual Studio 7.1 project file and a Unix Makefile, and have tested building it under both Windows and Red Hat Linux.

Data

All the data is provided at 30fps. We additionally provide higher-framerate (60fps, 120fps) data where it is available. There are 4 possible forcings here: (1) low wind, (2) medium wind, (3) high wind, and (4) rain. All .mot files that have an asterisk by them (*) were actually used in the paper; other data sets have been provided in case they prove useful.
