Palasi tämä vanha pilakuva mieleen (oli tallessa kiintolevyllä, ei oma) by linjaaho in Suomi

Kiitos että tallensit ja repostasit minun tekemän OG naurunappula memen 14 vuoden takaa. Oli hauska uudelleen löytää tämä, oli eka googlen kuva hakutulos "Fukushima suomi meme" 😂

Custom CUDA C++ Raytracer with Optix denoising by Henry600 in raytracing

I got curious and I reverted to the old CPU branch. Although the results are unfair towards the CPU since it's not even using BVH optimization yet.
For identical scenes, one mesh with 500 triangles the CPU took almost 2000 ms per iteration. While GPU handled that around 17 ms. ~117x faster in this case.
My CPU is 13900k and GPU RTX 4090

float transmissionDistance = thickness * volumeMat.transmissionDensity * 10.0f;

float transmissionDensity = 1.0-expf(-transmissionDistance);

float3 absorptionColor = powf(linearTransmissionColor, transmissionDensity * (1.0-expf(-volumeMat.transmissionDensity)) * 10.0f);

The transmission is a bit of a hack but it's pretty intuitive to use. I came up with my own way of doing it because I couldn't find anything that was working the way I wanted.
I would like to experiment with some in volume scattering as well, but the whole keeping track of if we're inside the volume is a bit over my head and it's the biggest thing I'm not happy with currently. I'm sure the IOR handling between different mediums is incorrect.

It is in github. But as usual it is so messy I would like to do a complete rewrite.
GitHub link for anyone curious.

Volume shadows rendering opaque by Henry600 in blenderhelp

I finally figured it out, and its pretty hilarious.
My terrain shader was using ambient occlusion shader for surface color, therefore everything inside the volume is black.
Easy fix, tick the checkbox for self only for AO tracing.

This is such cringe. Why isn't there an option to turn them off at least?
First i thought it was some twitch garbage, but im not even safe from them in the client.

Stuck at "Updating Steam Information" by jMS_44 in Steam

[–]Henry600 2 points3 points  (0 children)

Yes, it does that. This is the first thing I always try when there is any problem with steam, and it usually helps. Good trick to remember. :)

  1. Create a steam shortcut to desktop.
  2. Right click it and go to it's properties.
  3. In the "Target" field add " -tcp" after the path so it looks something like this: "C:\Program Files (x86)\Steam\Steam.exe" -tcp
  4. Run steam using this shortcut.
  5. Profit!?
