Lately, I’ve been focusing so much on Common Lisp itself, that I have barely spent any time on Ambienome, the whole reason I’ve been learning it. It has been so long that I can barely remember what I was working on. (Physics engine integration, I think?) That’s no good, so I wanted to take some [...]

The past several weeks have been a struggle, productivity-wise. First, I spent quite a lot of time working on proto-slots. That may seem productive, but the amount of effort I put into polishing and documenting it was way out of proportion to the benefit I would get from it. I think I did a pretty [...]

I got a bit sidetracked while working on creature components, but still ended up making important progress for the overall system. First, I created a new transform class by abstracting and cleaning up the shape class’s position, angle, and size attributes and methods. I also created a transformable “mixin” class, which can be used by [...]

Yesterday, I completed the code to generate triangle and circle meshes: The triangle looks like it’s too small, but it fits perfectly in the circle, and the circle fits perfectly in the square. Yay, geometry! Of course, when building a creature, they can be scaled to whatever size you like, and the algorithms can produce [...]

For the past several weeks, I’ve been learning “modern” OpenGL programming practices, by which I mean using a GLSL shader pipeline with vertex and fragment shaders. Even before starting Ambienome, I was already somewhat familiar with the old OpenGL “fixed function pipeline”, using glBegin/glEnd, glColor, glVertex, etc. Ambienome is going to be visually simple enough [...]
