Debug output of the result from the OpenCL tile frustum culling kernel.
The kernel divides the screen up into 32x32 pixel tiles. For each tile, the kernel then finds the minimum and maximum Z depth of the pixels in that tile through a reduction.
With this information, a bounding frustum is created for each tile and each point light's position + attenuation (affected area) in view space is then culled against this frustum.
The idea is that you can then get a list of all the lights that are affecting each tile, cutting down on the number of fragments you need to process for shading.
I'm currently using 2 separate kernels for min/max reduction and light culling - need to combine these as a next step for speed.
Quick realtime depth of field test. Each sphere is a weak deferred point light source with a random colour (high attenuation) - this causes all the different colours. A simple HDR tone mapping equation is used to adjust the exposure - without it, all the lights bunched in the center tend to turn a bright white.

Selected frames of a new video art piece submitted to Digital Graffiti 2015 using an updated particle painting engine created in openframeworks.
Unfortunately there is no documentation on this project. So in a few words ...
3D Scenes can be loaded in the application and animated in realtime. The content was projected on long layers of transparent material in an old beer brewery in Vienna.
This is my first collaboration with Yannick Jacquet (Antivj / Legoman).
Openframeworks + GLSL Geometry Shaders.

From a series of top ten explosions. This video was made with custom software that uses the colors and forms from explosions in action films to create 'abstract expressionist' paintings. The source for this composition was Speed.
combining the far infrared image from a handheld FLIR camera with the depth image from a kinect... brainstorming about multicamera alignment... really nice for tracking people in 3d.
