Messy cables? Worry not, we've seen the trend and added zip-ties to #AmplifyShaderEditor for #Unity3d 🔥

kinda crazy how small neural networks can be if you actually take the time to analize its output and struggles (here is a 2 input -> 2 tanh -> 2 tanh -> 1 output neural network which models a value in the ggx transform matrix)

hehehehe I remade the BRDF (GGX currently) plots from the LTC paper in blender

Let's talk about AI in VRChat. Be sure to fill out the Google form at the bottom of the article. ask.vrchat.com/t/regarding-...

I really hate unitys baked occlusion system, I completely understand why so few people use it.

today I learned you can hide everything except for the selected objects, while still maintaining the things that were hidden when you go to unhide, by pressing the fucking slash key.

yet another magic data texture I had to create RGBA8_UNorm 16x16 (z-order) 40 pixels left, all for some damn lightning

ohhh my god. I might actually have a valid use to train a neural network on something. LTCs GGX approximation uses a 3x3 matrix with five variables, which they normalize one to make it four and store that in a texture. They later just use two textures, but I dont like that.. z = f(x,y).. smooth.. :O

juuuust in case you were curious, these are my solutions to the width, height, and centroid of the Henyey-Greenstein Phase Function. I was trying to reparameterize it into a linear transform for reasons

incredible.

Literally half my notes are like this lol

ohh the half vector "normalize(lightDir + viewDir)" is the direction in which a surface normal reflects all the light from into the cameras view! Always wondered wtf the half vector was www.desmos.com/calculator/y...

a fun problem for the nerds www.desmos.com/calculator/s... this one actually has a very simple form!

im tellin you right now, dont sleep on avif as an image file format. the only downside I see so far is simply how long it takes to encode

dude im telling you, the people that designed power supply connectors on the power supply side Ḅ̶̢̛͎̗̹̖̯̽̾̊͝͝͠Ĕ̵̜̤̪̮͐̔̊͠ͅT̴̙̠͉͎͇̆̐̒͋̋͒͝͠ͅT̶̥͎̝̲̱̦͛̒͆̌̒́̑Ę̵̱̻͕̰̒̇̐Ř̶̙̣͎̫̯̺͌̃̓͋́̕͝ ̸̢͉̩̞̱̣̪̬͋̅B̸̠̙̹̯̈́̔̾̈́ͅḘ̴͍̦͈̣̿̂̉̓͊͝ͅ ̴̡̨̹̜̖̠̋̉̏̄M̵͍̼͉͍͍͔̯̰̐̈́̂̃̇́̚͠A̷̭̒̿K̶̼͋̏͂͗̈́̂Ī̷̡̦̹͓̝͑́ͅN̵̠̂̚ͅͅG̸͇̩̅̈ ̸̡̥̟̔͐͐̓̓͐̚͝S̶̛̬̘̹͖̭̭͔̒͑͌̔̋͝ͅĔ̴͎̌Á̸͓͎̩̳͔̖̱̀͜T̷̙̳̜͓̱͑̔̑͐͜ ̸͚͖̖͇̤̮̗̈͌̂̒̑͜B̷̹̉́E̶̡̦͉͂̿̄̎̑̕L̶̖̩͇͚̍͑͋̿̒T̷̨̮̰̬̻͉̲̍̏̕S̵͖̱͑

Found yet another project that I never had enough time to finish

good lord my desmos looks schizophrenic

I havent even finished this video and I've added like three things to my wtf list. This guys also making a camera emulation series as well; all round decent channel it seems youtu.be/5_Jy97TzZuM

shout out this website, pretty dope ciechanow.ski/lights-and-s...

@moi2x.bsky.social imagine getting your discord hacked smh

to the blender power users, do you have any extremely esoteric keybinds / Quick favourites that you set and actually use? mine off the top of my head are - Q: Reload Scripts (I do a lot of blender plugin stuff) - F1 -> Set Attribute (To set custom data for faces and such, like a vertex integer)

you know I find a certain type of beauty in doing things "well" in the sense of graphics. Like this shit lowkey dope looking as hell XD

Oh my god I figured out how to get blender orientations to work with unity. Do everything like you would in blender, but export with (image 1) then on the UNITY SIDE, enable (image 2) and apply. magically coordinates and rotations are the SAME.

I always see some crazy shit when im trying to do some outlandish stuff lol

fun fact: converting LinearEyeDepth to Linear01Depth is stupid fuckin easy. z_eye / far = z_01 and if you're using _ZBufferParams, the w component just so happens to be 1/far.. so z_eye * _ZBufferParams.w = z_01

Over time I may get back to pushing the rest of the shaders, but here's the spot light and point light. feel free to replace the normal reconstruction method if you wish. github.com/OwenTheProgr...

Distilled my normal reconstruction stuff over the past three years into something readible, sadly work in progress has been held up by job searching github.com/OwenTheProgr...

Spent the pass few days trying to make a PS1 gpu emulator as faithfully as possible. Still trying to figure out how theyd do the rasterization in hardware with fixed point math (the GTE is documented far more than the GPU is) and of course im curious if this will work with VR projection matrices :3

It seems I may be destined for Staples after all.
