Loneliness is when you implement a compute shader in Unity to render real, user-defined fisheye in RT, and you have no one to share your excitement with.

Fisheye? That's so fucking cool! What a complex operation!

#loneliness

No its opening a PR on a package and nobody reviews it. Forever alone

Wait what you can do compute shaders in Unity?

@monzrmango Yup, they have a class called ComputeShader. I implemented mine in HLSL, but they probably support other shading languages.

@NickyBones just curious what college did you go to learn all those stuff CUDA and etc or you are self learner?

I always find fascinating dev with skills like yours

@echonox I graduated electrical engineering + physics. Uni basically taught me how to sit my ass down and learn by myself. After that, I just picked up whatever I thought was interesting and struggled with it until it surrendered :)

That is so cool. Wanna show the effect?
And awesome meeting another liked-electrical-engineering-but-went-with-software-persona

@jespersh I have a small bug because I'm modeling the fisheye according to the OpenCV model - it has issue near 180°. My team insisted that we used that calibration model, so I have this weird external ring.

@NickyBones the external ring does appear to be the same image but flipped on the x-axis.
However, it does look great
💯👌

@jespersh It's flipped around the x-axis and also on the y-axis (left goes to right and vice versa). I suspect OpenCV's undistort function goes berserk when you're over 180...

@jespersh Managed to fix it! Just had to define the fisheye radius as a series of thetas instead of the ideal R=f*theta

Sick! I just checked your GitHub as well and Fullmetalengine ? I'm into that stuff ! (I'm gonna fork it for sure) I'm still noob at openGL though. So is it fun implementing physics for once ?

@TheAnimatrix The physics part in FullMetalEngine is actually the less tested one - I stopped in early-development because I had to work on the Unity stuff. The Graphics engine is alright if you want to get a feel of OpenGL but my architecture probably sucks.
