WangLu's Notes

The video, made in 1994, explains the sphere eversion problem and visualizes one solution: Thurston's corrugations. More information can be found in the following links: 1 , 2 , 3 . There is also an HD version . The animations in the video are really fascinating. I figured it'd be a good excercise to recreate it with Blender, especially with geometry nodes. However I immediately got stuck after 20 minutes, because I had no clue how everything works. Luckily I found a port  of the original source code. (The original source code  seems no longer available). The author also created a nice video . I'll refer this version as  mathIsART's version. I also found another port , which I'll refer to as McGuffin's version. Mostly I studied mathIsART's version, and occasionally used McGuffin's version as reference. The code was really fun to read, and I ...

Overview Because of reasons, I felt that I have to materialize my ideas before they drive me crazy. Gleitschirmfliegen The Game is one of my biggest projects in the past few years. In total it took me ~270 hours for editing, plus ~400 hours for rendering (including tests). The development process is a mixture of learning, having fun and self torturing. Quite a few things should be worth a few notes. Intro & Credits Intro and Credits are the easiest and most fun sections to make. Shotcut is my video editing tool of choice, because it's free and it supports webvfx. Since last year I've been experimenting with webvfx for the telemetry overlay of my pargliding videos. There are issues here and there, but overall it's a great tool. I tried two new video filters, Sketch and Cartoon. Sketch worked well, and I applied it to the video. Cartoon didn't. Spiral The spiral scene is apparently the most important one. At some point I came up with this joke id...
