GSoC Light Paint, Stage 1

Posted on by

lightpaint-example-dinosaurArticle submitted by Chris Want. Student Jingyuan Huang (aka yukishiro) has been working hard on her Google Summer of Code project “Blender Light Paint using Spherical Harmonics”, an interactive tool for artists to create, modify, and preview image-based lighting environments specified by HDR light probe images.

With the Summer of Code midterm just around the corner, she has uploaded some “Stage 1″ release binaries to http://www.graphicall.org for user testing. People wanting to try out this project should check out the user manual.

Feedback on the project can be left either at graphicall.org, or at the 2009 Summer of Code mailing list.

To learn more about the details of the Light Paint project, please check out the project proposal and the user/design specifications for the project:

      Great job!

      It’s interesting that they’re using spherical harmonics. I had run across the concept of spherical harmonics in a Nuke video and posted info at blender.org about it:

      I thought it would be a useful tool in the rendering process. Apparently the blender folk already aware of it. It seems like it will be an excellent rendering tool.

      Wow, I was being shown something similar in Houdini the other day. Adds a lot to be able to preview your hdri lightdome.

      The lack of a windows build seems to be because of a linking problem with the Lapack libraries.

      Just when you think you are finally starting to make serious inroads on learning how to use all the new features flying at you, more keeping piling on. Oh well, that’s what makes Blender great….

      oh wow, week ago I was looking at spherical harmonics whitepapers. This technique is really suitable for dynamic real-time global illumination and ambient occlusion, it only requires some time to compute it.
      Btw, is this going to to work in Game Engine?

    • Sleeper

      I think you can now get a Windows build here.

      Does this new feature mean that HDRI ligthting will now be available in blender?
