Felix decided to go beyond the boundaries of not only the universe but also the canvas... In principle, nothing else was expected from him! (again, scribbles on the TwT phone)

Феликс решил выйти за рамки не только вселенной но и холста...Другого от него в принципе и не ожидалось!( опять каляки маляки на телефоне TwT)

Is it possible to deduce the shape of a drum from the sounds it makes? This is the kind of question that Iosif Polterovich, a professor in the Department of Mathematics and Statistics at Université de Montréal, likes to ask. Polterovich uses spectral geometry, a branch of mathematics, to understand physical phenomena involving wave propagation. Last summer, Polterovich and his international collaborators—Nikolay Filonov, Michael Levitin and David Sher—proved a special case of a famous conjecture in spectral geometry formulated in 1954 by the eminent Hungarian-American mathematician George Pólya. The conjecture bears on the estimation of the frequencies of a round drum or, in mathematical terms, the eigenvalues of a disk.

just use the rounded rectangle shape tool girls its in the menu for a reason

i'm about to crash tf out can someone just like. tell me it's gonna be okay lmao

CT scanner in Blender almost working now.

Leftmost image is the source I'm using. Center image is the 'xray' image that I created from the source. With enough 'xray' images from different angles the source object should be recreatable, and that what the rightmost image is suppose to be.

My previous attempt used 250 cubes rotates around with volume shaders to produce a fog of the object. This causes some problems as the fogs dont really 'add' in blender and was hitting some limits in the depth cause not enough information to come through.

This new method uses geometry nodes. Instead of creating the fogs through the shader and rendering it is done using geometry nodes at runtime.

each node holds a small instruction set that adds the image at a small rotation. Each node was created by hand, as geo nodes scripting is a little different from shader nodes scripting and this process really wasnt that difficult to do (mostly just me remembering how many nodes I need to create as I can copy paste blocks).

With this being done in geo nodes I can also do more to the object. Something I see from CT scanners is slicing up the created object to view slices.

With geo nodes this is quite easy and in theory I should be able to start pulling internal data if I had any to begin with.

I think at this point its a problem with the 'xrays' I made. There should be a way to make them better as it was something I made in 20 minutes after a job interview about Tomography. But thats for later, my back hurts and I'm starting to see grid lines from all those nodes.

Shoutout to that one weirdo who told me to continue. You understand.

It's bout time I make use of my skills with rigorous drawing and draw a church I think

at first I thought school beyond 5th grade was useless but I recently discovered that it teaches me about anxiety and not to procrastinate
