Replaced the previous KD-tree (for caching points) with a BVH-tree (thanks to Andre 'jaguarandi' Pinto for help here!). The bvh is quite a bit faster and doesn't suffer some of the artifacts that were apparent with the kd-tree. I've also added a choice of falloff types: Standard, Smooth, and Sharp. Standard gives a harder edge, easier to see individual particles, and when used with a larger radius, Smooth and Sharp falloffs make a much cloudier appearance possible. See the image below (note the settings and render times too) http://mke3.net/blender/devel/rendering/volumetrics/pointdensity_bvh.jpg
Welcome to the fun world of open source. For instructions on building and installing Blender, please see the file named INSTALL. ---------------------.Blanguages and the .blender directory--------------------- The .blender directory holds various data files for Blender. In the 2.28a release those are the .Blanguages file containing a list of translations, the translations themselves and a default ttf font. Blender checks for the presence of this directory in several locations: - the current directory - your home directory - On OSX, the blender bundle is also checked - On Windows, the installation dir is checked. If you get a 'File ".Blanguages" not found' warning, try to copy the .blender dir to one of these locations (your home directory being recommended). -------------------------------------Links-------------------------------------- Getting Involved: http://www.blender.org/community/get-involved Community: http://www.blender.org/Community Main blender development site: http://www.blender.org The Blender project homepage: http://projects.blender.org/projects/bf-blender Documentation: http://www.blender.org/education-help Bug tracker: http://www.blender.org/development/report-a-bug Feature request tracker: http://wiki.blender.org/index.php/Requests
