There is still huge room for improvements, both in terms of performance and visual quality. However, they are also the most expensive compute due to their primitive distributions and how many incoherent rays that must be traced to simulate the indoor indirect lighting. In particular, “sponza”, “conference”, “sibenik”, and “fireplace_room” are all interior scenes that can give very interesting light interaction results. The iconic dragon model, though it requires quite some GPU power to renderīesides small standalone models, there are also some interior scenes that are interesting to tweak. Hit “Load Model” to pick one that sounds interesting to you. If you aren’t happy with this dull looking monkey, you can try other models that came with the demo. It is the direction pointing towards sun light. The only field that needs a bit explaining is the “L” field. Simply hold down on the fields and drag around to edit their values.
#OPENGL 4.4 DEMO INSTALL#
Since there is no install target we can use, installation. You can edit lighting state with the UI, whose control should be quite self-evident. This gains compatibility with X.Org 6.8, but breaks it with XFree86 4.4, so flip the IGNORE switch. To orient your camera, simply use your mouse to drag across the screen. Use WASD to move horizontally, X to move up, and Z to move down. Originally, I was using intel’s integrated graphics card and the version of OpenGL on my win7 is only 1.1.

#OPENGL 4.4 DEMO DRIVER#
But after I installed the newest driver (version 337.81, released on perhaps May 13, 2014), the version of OpenGL is not upgraded. The newest driver provided by nVidia is claimed to support latest OpenGL version 4.4. You can increase the bounce count to see indirect lighting, but the computation becomes more and more expensive at every extra bounce:Ī path traced monkey with 2 bounces of indirect light Hi, I have just installed a nVidia Geforce GT640 graphics card. I also set the initial light bounce count to 1, just so you can see how well your machine is holding up against CRay. I picked the monkey as the startup model since it’s only 500 faces, and should be able to be ran on most GPUs. Upon startup, you should be greeted with a monkey, like this:
#OPENGL 4.4 DEMO WINDOWS 10#
Windows 10 (will work on compatibility later)Īt least 2GB of memory (as for now, will be improved on this later) OpenGL Extension Viewer is reliable software which displays the vendor name, the version implemented, the renderer name, and the extensions of the current OpenGL 3D accelerator. So if you see any unexpected error messages pop up, please report them to CRay’s forum as it will help me to identify these bugs and make CRay more robust. Keep in mind that it is very likely for there to be a bug in CRay that is only triggered on certain machines (it’s OpenGL, after all). Now I will provide a short tutorial on the basic controls and what you should expect to see. The project is accepted earlier than I anticipated, so I scrambled to make a (hopefully) good-enough demo for people to play around with. Hi guys, it’s an honor to have CRay be featured on the handmade network.
