Houdini Cracking Tool

The creation of real-world phenomena is a very common task in CGI and visual effects. From tornados to avalanches, from apocalyptic tsunamis to earthquakes. For the CGI Techniques module at the NCCA, cracks as they occur in earthquakes have been investigated further. A Houdini Digital Asset has been built to allow easy creation and artistic control of a crack on a given surface. The report (see download below) documents the background research and explains technical aspects. Furthermore, the key problems during implementation are explained and the solutions presented.

Here are some screenshots of possible results (taken from the report):

The video above explains its usage and current limitations. There’s still a lot of work to do and optimisations to be done. Feel free to get the Houdini source files below.
