Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Try doing some searches in the UnrealEngine github repo. I don't know if DirectCompute, CUDA, or OpenCL are used, but I do see quite a bit of OpenGL in /Engine/Source/Runtime/OpenGLDrv. Check the /Engine/Source/Runtime folder and search through there.

Well UE4 got OpenGL renderer which is used on Linux and OS X (and you can even use it in Windows if you want by starting editor with -opengl or -opengl4 options), so it's kind of obviues it's there ;p

When i browse source i see lot of PhysX refrences in terms of GPU computing, not sure about other once. Try searching libarary calls in github :p Unreal is made seemless, trying to connect lot of platfrom APIs to common interface, so you don't need to worry what it uses and most importently what UE4 will use in future
