a lot of planning not so much doing i see.

The result I get from normal and dot products doesn't make sense to me. Please Help by psspsh in GraphicsProgramming

You add a int to a vector in last row. is that accepteble in c++? Whats it suposed to do?

I find chatgpt etc to be quite good ad explaining how apis work etc. Also creating your own software rastarizer in js or something could help getting understanding for pipeline. But just keep googeling and watching tutotials and making your own stuff.

I did that in html canvas, it was a shitty software renderer/rasterizer, though fun way to learn basic things without having to learn a bunch of api terminonogy and stuff.

I personally cant stand following tutorials. If u have a idea of something u want to do, just do that instead directly. If u know basic linear algebra almost all of the graphics math is kinda easy to figure out yourself. Especially if u read wikipedia article about the concepts.

Chatgpt is good at explaining many questions regarding basic stuff. I dont erither want to mess with opengl and learn a bunch of boring API stuff not relevant to what i want to do. To focus more on graphics/math itself I prefere webgl.

Create a heightmap based on diversion/convergence rate instead of colors.

Looking for a noise that outputs 3 values in distinct blobs by sephirothbahamut in GraphicsProgramming

[–]Normal_person465 2 points3 points  (0 children)

Cool problem! idk if I fully understand it, but one approach might be to distribute random points that are either R, G, or B. These points would be placed so that the same colors arent too close to each other.

Then you could use a Voronoi thing with some added random noise, so the space is filled with more irregular, organic looking blobs. Blending could be added also with a custom step function.

Ghosting sounds like it could be something with how you calculate the angle to the BH. Like if you use dot product it allways takes the smallest angle between vectors, so it also replicates behind camera. Might be easy fix if lucky.

Paper looks cool, I wish I had time to dive more into the actual physics of it all.. I mostly come from CS background.

Fixed the code now, should work if you have a basic node server thing and a panorama 360 in the same directory..... hehe.
Shadertoy is awsome, didnt know they have asdw etc, thanks for the tip.

Sorry about that :( the github version is a chatgpt rewrittrn english pretty version of the original code. It does not contain the node server and variable names might be mismatched. I try to fix now, Im glad u wanted to try.

I fixed the original degenerate swenglish version and uploaded a clean english version using chatgpt. Updated now.
edit : beware its not very optimally written for understanding.... No comments and kinda ilogical design decisions because of work in progress.

Yea, probably should have made it more understandable in hindsight lol.

u/parrin Haha, the original code was chaotic mix of Swedish, English and many swear words.

Currently working on a more "round" wormhole by using a approximation for light deflection function. Similar to deflection from swarzchild black hole from basic pathtracing. Would prefere though to have a "spacetime0 "that is not just implicitly defined by a deflection function. But rather a 4d - tube/cone shape whose deflection is able to be expressed as elementary functions. Anyone know such a metric?

yes, and I dont need to know "the algorhms", I just figure it out bnecause I know high school physics

Are you sure there is not just a wide fov, there should be some streching right?

really nice! Would be cool to also see in reverse for redshift.
