Thin films in production with extended anisotropic kernels

Paul Kilgo, Jamie Pilgrim, Parag Havaldar, Ashraf Ghoniem
2022 Special Interest Group on Computer Graphics and Interactive Techniques Conference Talks  
A second node consumes the transform and point data, and computes an implicit function using the point position data, outputting the result as either an OpenVDB [Museth 2013 ] level set or fog volume.  ...  We implement this step in a second SOP using OpenVDB. The first step is to compute the active voxels defined by the particles. To do this, we compute a bounding box defined by each particle.  ...
