Danny Cho – Generative Landscape

For this project, I was inspired by some of the previous works done in the past 15-104 classes. Especially the ones that were done regarding the concepts of the shooting stars and lamps inspired me. I tried to replicate the frame of the lamps with the detail feature of the sphere function as well as showing the glow by creating multiple translucent sphere in and out of them.

It takes some time for the lamps to start appearing unless you drag around the screen to look for them.
