Plotting a function in openGL

I remember being intrigued back in the day about how did the Graph Plotter node in Unreal Engine worked.
I always saw that due to the uneven UVs aspect ratio it created glitches, stretching the plotting line.
This is obviously a minor issue, but I tried to research how to avoid this.

It turns out that using the gradient of the function can fix this, because it creates a "height map" following the line of biggest grow.
The maths behind this require a good background in algebra and it is very nicely explained in the following link at Iñigo Quilez website (a great source of computer graphics knowledge).

He also implemented it very nicely in this link:

I will have a look in the future at filly implementing this in Unity.

Have a great rest of your day,

UNITY - Gerstner Waves in Unity

I have implemented a Gerstner system in Unity. This was done with the help of several tutorials I found on the internet. I am quite happy with the result. I guess the next step is to add a proper water shader!

The waves are generated in the shader directly and it supports up to 3 waves added together.
Another thing I would like to have a look in the future is to calculate this in the CPU and movingthe verteces directly in the CPU.

Kind regards,

UNITY - SDF in Unity

So just to continue with my SDF and Ray marching adventure I implemented it inside unity, using a very similar shader. This was done with the help of all the great people on theinternet!

First Ray Marcher

I have been wanted to have a look at this for a while and I finally found the time to do it.
This is a very interesting subject for me because this simple concept can develop into much more complex ideas, like generate a beautiful looking cloud system.
