RiftRay updated for 0.8 SDK

[jimbo00000]

Hi everyone,

I've updated RiftRay for the 0.8 SDK - you can download the latest build here: https://github.com/jimbo00000/RiftRay/releases/latest. I'm hoping to have it polished up enough to release on share in time for the Rift's consumer release. At the very least, I think I have a shot at the record for smallest download! 🙂

Here's a video of an older version, all the beautiful shaders are still the same:

Any feedback is appreciated!

That... is impressive work. I'm surprised you've managed to get that sort of thing to render correctly on the Rift.

All thanks to this post: http://blog.hvidtfeldts.net/index.php/2 ... -polygons/ - I can't recommend reading it highly enough.

If you're tired of polygons altogether or looking for a new way to do modeling, hg_sdf(http://mercury.sexy/hg_sdf/) is now included in RiftRay too.

I've always been interested in looking at alternative ways to model (not poly or voxel), it still seems like you'll need to 'code' to model but I'll take a look. I'm interested how you got stereo rendering to work as the typical way graphics cards render 3d graphics is thrown out of the window. Do you know if anyone has made a modeller with a user interface yet? even if it's basic/lacking features.

I'm also interested on how texturing or adding 'surface detail' works with this.

I'd say only half of it is thrown out the window - the geometry processing phase(projection, clipping, culling) is skipped and transformations get pushed into the fragment fill phase. The same modelview and projection matrices we could have used for polys get applied to rays instead. iq comments here: https://www.shadertoy.com/view/XdlGzn

I'm also interested on how texturing or adding 'surface detail' works with this.

This example is the most relevant I could find: https://www.shadertoy.com/view/4sXGD2 (I think the function surface extract_surface(vec4 p) is the first time I've ever seen the .tpq swizzle coordinates.) And there are some more ways to texture quads and spheres:

I am not aware of any such project. One could certainly feed data from a motion tracked controller such as Touch, Vive or Hydra into a uniform buffer to move primitives around manually.

Wow, freaking amazing. Thanks for sharing this! 😮

Very impressive indeed! Too bad my frame rate was so slow on many of the scenes, but the renderings were great.

Thanks a lot! You can increase your frame rate by adjusting resolution and vertical FOV(unless you're looking at just a thin, blurry strip already). What kind of GPU do you have?

Someone just has, and it is awesome:
