Welcome to Pekka's fascinating graphics coding and hobbyist programming website.

Professionally, I am a software engineer. I've worked with virtual reality tech, 3D scanning, mesh optimization, and 2D display drivers. On this site I try to explain niche technical subjects in clear language.

Explainers:

• Classic 3D videogame shadow techniques (October 25th, 2024)
  graphics, games, historical
• Shader post-processing in a hurry (April 6th, 2024)
  graphics, shaders
• Clean pointer serialization in C (January 21st, 2024)
  serialization, technique
• Sort a sphere BVH with split planes (January 10, 2024)
  graphics, algorithms, fundamentals
• Annoying details of a Z-buffer rasterizer (January 4th, 2024)
  graphics, meshes
• Going up in color bit depth (November 8th, 2023)
  fundamentals
• In-place filtering of an array (March 22nd, 2023)
  C++, algorithms
• BSP Lessons (March 7th, 2023)
  graphics, meshes, quakeology
• Full screen triangle optimization (February 27th, 2023)
  graphics, OpenGL

Notebooks:

• Moving basis decomposition for images (March 16th, 2024)
  machine learning, graphics, compression
• Color quantization with a self-organizing map (March 8th, 2024)
  compression, machine learning
• PCA image color compression experiment (March 5th, 2024)
  compression, graphics
• Image vector quantization is just like creating a tilemap (April 30th, 2023)
