Faux sphere render + interactive lighting

on CodePen.

Quick and dirty lighted “sphere” likeness using circle radius calculation for the color intensity value. We shift the “lighting” around by adding/subtracting to the color intensity amount of a pixel on the “sphere”, this amount is based on the current x, y position of the pixel multiplied by horizontal and vertical constants. Those are modulated by the current mouse x, y mouse cursor position as percentage of the inner window dimensions. The green/zombie’s “eye” was a logo that I used when branding the games/ graphics demos, etc. that I would write way back when in the ’90s.

Playing around with some silly concepts like solving the famous/infamous?! … FizzBuzz interview problem without using conditional logic, I ended up getting distracted and writing a small article on optimization *shrugs*… bellow is link to in on Medium where I published it.


This is a Raycaster I created from scratch,written in Javascript that uses an unconventional algorithm I came up with. It was a fun exercise in thinking, starting at trigonometry and coding an algorithm that worked. Once I finish up a few more details in the code I will put up blog post here describing things in more detail. For now you can click the link below and play around with the raycaster engine, a very very un-optimized, zero error checking raycaster engine, but in the words of Boltr, “She chooches!”
