I made VRC Light Volumes, I guess?

[RED_SIM @RED_SIM]

VRC Light Volumes v.3.0.0 released!
New features: EVSM shadows, separate speculars, light clustering, animated cookies, area light cookies, shader stripping, improved performance and more!

@CherryTruthy I use a grating dictionary as well. Getting neighboring tracks in phase is an open problem for me too.

I managed to make 3D holograms on Blu-ray disks. And they are much more detailed and clear than DVDs. Here's a part of Tokyo I got from Google Earth and turned into a hologram.

[RED_SIM @RED_SIM]

@z_thomas7 It is. First I thought that verbatim MABL would be bad because of how dark it is, but it actually even brings more contrast.

[RED_SIM @RED_SIM]

@LithiumOxalate The marks act like tiny diffraction gratings. They control how bright each patch looks from different angles, so your two eyes get slightly different views of the same scene. That's where the depth comes from.

@ded_ortem Not yet, but I might work on it later

[RED_SIM @RED_SIM]

@CherryTruthy I keep EFMPlus on DVD. I work backward from the channel patterns I want to input bytes that produce them through the drive's stock encoder. Same idea on Blu-ray with 17PP

[RED_SIM @RED_SIM]

@CherryTruthy Yep! I use the mark patterns along each track to send different views in different directions. So it works correctly along the tracks only.

@CryptoSpaces1 If you look closer, you'll see stereo parallax here, so it is engraving, but not "just an engraving" ;D

[RED_SIM @RED_SIM]

@christothecium It is a 3D hologram. Maybe the video I posted doesn't make it that obvious, but all the buildings can be seen not just as a single-view stereo, but 3D from different angles.

@petimi4 正直でいることは大切だけど、正直に話していい時と、そうでない時を理解していることも大切だと思う。何事も極端に走るのは良くないと思うし、それは誠実さに限らず、世の中のあらゆることに言えることだと思う。

[RED_SIM @RED_SIM]

@Michael_Moroz_ @ShaderFes Yes

[RED_SIM @RED_SIM]

I didn't have time to make anything for @ShaderFes. Oh well, hopefully will make something for the next one...

[RED_SIM @RED_SIM]

Okay... I made them colored! Very washed out, but correctly colored! I didn't expect it's even possible with such low engraving precision O: Both holograms here are still stereoscopic.

[RED_SIM @RED_SIM]

I managed to make a 3D hologram of Chocolat and Plum on a DVD disk using a regular DVD-RW drive. With human eyes it feels like they actually 3D floating on the surface of the disk. Maybe I should release an app to make holograms of your VRChat avatars...

[RED_SIM @RED_SIM]

Everyone are obsessed with DVD image engraving... But look what I managed to achieve - an actual stereoscopic hologram. It actually looks like it's 3D while observed with human eyes! Amime girls holograms next?

[RED_SIM @RED_SIM]

@tomtomaru It's possible, but hard to make all the image a stereo hologram

[RED_SIM @RED_SIM]

@DyLhun I'll try to make it as an app. Right now it requires manual calibration and doesn't have good control of what you get at the end. I wasted a lot of discs to achieve what I have now :D

[RED_SIM @RED_SIM]

@KevinVFX It's just data. I used a DVD-RW drive to write it to a disk, and that's it, just an iso file. And it has enough precision to engrave a diffraction pattern that can form a hologram.

[RED_SIM @RED_SIM]

By the way, the Steam Link bug I reported, was finally completely fixed. Now image clarity is perfect!

I want to talk about a big Steam Frame problem no one seems to mention: image quality. SteamVR's streaming pipeline has a serious bug that blurs high-contrast edges. I managed to partially fix it. These are real screenshots from the headset after decoding and lens correction.

@rustybeans_ Irl shaders unlocked!
