Small C++ Reflection Demo

I created a small demonstration program that explains the core ideas behind implementing a custom reflection system for C++. More might be written in this post in the future — for now I’m just storing the demo right here on this webpage:

 

Nearly Geodesic Sphere – Mesh Creation

Capture

This post will let me store some useful code and possibly share it with others. I had originally found this wonderful explanation on stack overflow on how to generate triangles in a super simple manner for a nice sphere mesh. The idea is to take an octohedron, or icosahedron, and Continue Reading →

Inertia Tensor – Capsule

Capsule

A capsule is defined by two hemispheres and a cylinder. Capsules are pretty useful geometry for collision detection since they are easily defined mathematically (implicitly defined). This means that minimal information can be stored in memory to represent a capsule in 3D space. Given a radius value and position information Continue Reading →

Memory Management

Any competent software engineer will have spent significant time working with low level memory management. Even though the operating system code is written for will often provide some kind of allocation and deallocation mechanism, application specific assumptions can be made to increase memory related performance. For example certain hardware doesn’t Continue Reading →
