This is not good (It's very rudemantery), I'm not even storing the heihgt values in z, they're stored in x of the heightMap LMAO! But it's alright, works kinda as intended! My first ray marching exercise. I was inspired by 'Barney Codes' video.. Was much easier than expected after I learnt screenQuads and FrameBuffers and Render Textures

Used SHADERed for this!
