I want to build to Houdini renderer(of my friend) through HDK.
I found this page: http://www.sidefx.com/docs/hdk12.0/hdk_opbasics_rops.html [sidefx.com] and check two(only) examples, but still I dont know, how I can create render window and set data(pixels) to some render matrix. Because both examples have only file output

I found few projects, where VRay and Arnold were build to houdini, but I cannot find any source code. And also will be great to use IPR rendering too!
