Weekend Shaders

These are little shader artworks I do on the weekend.

🗓️ Shader Logs

Sunday, April 5 - OBJ Rendering

I wrote a simple program that takes a OBJ file and creates a shader program that renders the geometry. Examples from a sample dataset are provided in the file.

python obj_renderer.py input.obj

Sunday, August 24 - Infinite Tower of Lire

I wrote a program that renders an infinite stack of blocks at a harmonic offset. The effect resembles a waterfall of blocks being stacked on top of each other. Inspired by a math video I was watching on YouTube about the subject.

Saturday, August 3 - SDF Tunnel

I wrote a program that renders a tunnel full of hexagons inspired by an old game I used to play called Run. The curve of the tunnel can be adjusted using the mouse.

Saturday, July 6 - SVG to Shader Compiler

I wrote a program which compiles a svg to a shader. Currently the program is very simple and does not do any optimization.

python svg_to_shader.py input.svg

Saturday, June 27 – Katana

I drew a katana with simple shapes and gave the blade a gradient. It would be cool to animate in the future.

Sunday, June 15 – Procedural Character Animation

More procedural character movement added a wiggle and jumping movement.

Sunday, June 15 – Neural Network Visualization

I wanted to write a program to visualize a fully connected neural network. I used a different color gradient for each network connection in combination with each layer.

Sunday, June 15 – Voxel Raymarching Chicken

I used voxels to design a chicken and rendered it using raymarching.

Sunday, June 1 – Procedural Snake Animation

I animated a snake procedurally. The snake body segments follow a smooth trajectory.

Saturday, May 24 – Grass Movement

I simulated a bunch of little grass pieces being moved by the wind. I liked the color palette I used.

Friday, May 23 – Ray Marching Letters

I drew the first letter of my name "M" using Ray Marching and a custom signed distance function (SDF). In future work I could try to render more complex tetrahedra

Sunday, May 18 – Procedural Trees

I wanted to see if I could draw procedurally generated 2d trees as a shader. I had seen some examples, but was wondering if I could do something similar to the recursive approach inside a shader.

Sunday, May 11 – Starfield

I turned my old highschool project below into a shader.
