OpenVDB Bienvenue sur le site mindmapping.com ! pqhoudini This small site contains project files for my tutorials on vimeo - in the Project Files directory available on the left. It also contains the vimeo tutorials in categorised by subject - see the links on the left. Of course it's not always straightforward to categorise videos which cover several subjects, so the boundaries are not rigid. For all of these tutorials some basic knowledge of Houdini is assumed - at a minimum having mastered all the introductory videos that come as part of the 'Start Here' help. Its worth checking the Vimeo description of each of the videos (which is accessible once you've linked through to the video on Vimeo) for dependencies between the videos - obviously the videos that come in a numbered series are best watched in order - but also some series are best watched after other, more basic, videos. If you have found my tutorials useful do think about donating a few dollars / pounds / euros to help cover my costs.
Deforming RBDs Simple setup that uses a SOP solver and deforms the geo at points of impact. The impact data is already available in the SOP solver, the normal is the impact direction and there is a pscale attribute for the magnitude of the impact. In this setup I just used attributeTransfer to get the impact data onto the mesh, then a vopsop to deform the mesh. There is a minimum impact so that resting objects don't get deformed. Also I divide the impact magnitude by the mass... the heavy box was denting itself from just resting there. Houdini - Impact deformation for RBDs from Sam Hancock on Vimeo. Also going to try getting some volume preservation going on!
