VDB activate from points

A SOP node created in HDK which activates voxels in VDB volume at positions of input pointcloud. You can check a tutorial I wrote about writhing this tool.

Setup guide

1. clone this repository, create a folder for building

$ git clone https://github.com/jtomori/VDB_activate_from_points.git
$ cd VDB_activate_from_points
$ mkdir build

2. source Houdini environment variables

$ cd /opt/hfs16.0.736
$ source houdini_install

3. if g++ command in your environment refers to version different from Houdini one

$ export CC=/usr/bin/gcc-4.8
$ export CXX=/usr/bin/g++-4.8

4. set compiler flag and build using Houdini hcustom util

$ export HCUSTOM_CFLAGS="-DOPENVDB_3_ABI_COMPATIBLE"
$ hcustom -i build/ -e -L $HDSO -l openvdb_sesi src/vdb_activate_from_points.C

5. enable displaying of DSO errors (for debugging) and tell Houdini where to find the node, run Houdini and use the node :)

$ export HOUDINI_DSO_ERROR=1
$ export HOUDINI_DSO_PATH="/your_path/VDB_activate_from_points/build:&"
$ houdini -foreground
