I’ve had some time off recently and decided to re-create and share a bunch of tools I end up making all over again ever different place I work. First one that’s ready I call ‘volume smear’: github.com/mattebb/hda/tree/master/volume_smear
Kind of like a directional blur for volumes, can do along a single direction vector or based on a velocity field
can be for smoothing volume surfaces along velocity vectors github.com/mattebb/hda/raw/master/examples/images/volume_smear_particles.jpg
or smearing density/colour volumes, with custom filter kernels, like this one which smears with a spectrum kernel github.com/mattebb/hda/raw/master/examples/images/volume_smear_spectrum.gif
will re-package as full version HDA next time I get a full non-indie license
