Computer Graphics

3D computer graphics written in code completed by writing to a fragment shader.

There are 4 parts to the code: vertex shader, fragment shader, render, and events.

Aurora Lights

Inspired by the Japanese photographer Hiroshi Sugimoto’s work Opticks 053.

Completed by writing to the fragment shader. Input to the fragment shader is x, y and time.

The movement of the colors is controlled by the time variable.

Blue Moon

This piece is inspired by a line from a book I liked:

"That year I was 17. When I went to the wild at night, I saw that the night sky was like a pool of purple water. The stars were bright spots that did not move. The night wind is some light blue streamlines, and echos came from the clouds. I was very happy at that moment, which shows that I can be a poet. According to my opinion, anyone who can feel a moment of joy in this world of endless troubles and hatreds can be regarded as a poet."

Moon is completed by ray tracing to a sphere. I also added tiny light particles the the scene by pushing more spheres into the scene through an array. Their movements are random and controlled by the Math.random() function.
