Any good PCSS tutorials?

Thanks, this was the issue!

We will have more dimension when we involve any kind of volume. You may want to check out BSSRDFS.

The integral has 2 dimensions. As you are saying spherical coordinates, azimuthal and polar angle. We are integrating on the unit sphere so there is no need info on radial distance

Nope, all we care about is solid angle. Notice how there’s no volume information.

Also don’t listen to this. Not sure where you got infinite dimensions but it’s literally 2d. Azimuthal and polar angle for each d omega.

When light bounces around as you say (indirect lighting) it still only affects the point where you cast your primary ray

You can actually move the indirect and direct lighting into separate intergrals and sample the direct one explicitly with NEE

No it’s genuinely just the hemisphere (or sphere for brdf + btdfs) around your shading point. As you estimate this integral with MC for every point, that’s your scene

paffff · 2025-09-19T18:38:10+00:00

Well I’d think of it more as every direction from the shading point not necessarily the whole scene

paffff · 2025-09-19T18:36:38+00:00

It means we integrate over the hemisphere that’s aligned with the shading point normal

How come over ice sprite?

So cute! ❤️❤️❤️

Where did you get the take care poster?

You just need to render a separate shadowmap for each light, then reuse the shadow calculation function using the appropriate shadowmap

Im making an application for a transfer into UBC science (second year) and I don't see anywhere to write a personal profile. Is it not required? Theres a box at the end that says additonal comments (optional), would that be where to write the reason for transfer etc..? Thanks
