It seems that the octree has been built correctly. Going to use bitset to count children, not sure how I'm going to determine what quadrants they lie in. Perhaps masks? 		8 years ago
assets Textures were suprisingly trivial with the plane intersection code hashed out 8 years ago
include It seems that the octree has been built correctly. Going to use bitset to count children, not sure how I'm going to determine what quadrants they lie in. Perhaps masks? 8 years ago
kernels SFML packets have no documented structure so I had to packet them out myself. Low Energy 8 years ago
notes Various tweaks and modifications 8 years ago
shaders Got some geometry up and rotating. It will be pretty trivial to pass in 8 years ago

.gitignore Added a quick printout of the hardware info. Running into a problem choosing between platforms, going to abstract CL out into it's own class and hide all that logic 8 years ago
CMakeLists.txt Not sure if I'm a huge fan that I have to specify the folders in the includes now 8 years ago
FindSFML.cmake Added a quick printout of the hardware info. Running into a problem choosing between platforms, going to abstract CL out into it's own class and hide all that logic 8 years ago

README.md

In order to build this project you must have Cmake, GLEW, SFML, and the OpenCL development libraries installed / downloaded. You're also going to need OpenCL compatable hardware that supports the cl_khr_gl_sharing extension. The VS2015 build is working, Linux compiles but I don't have hardware that works, and Mac should compile and run, but I don't have access to a Mac.

Note on cl_khr_gl_sharing: The cl_khr_gl_sharing extension, or cl_APPLE_gl_sharing for macOS, is only supported on certain hardware. Further, cl_khr_gl_sharing is not supported on intel CPU's running linux. You might be able to install and use beignet to get around this. The program will warn you if your CL device doesn't support this extension.

Featuring...
