The Coronavirus Curve – A simple simulator
Here is an implementation for a simple ODE simulation of the COVID-19 curve. The simulator runs based on a set of first order ordinary differential equations (ODEs). These equations are dependent and measure three values including the change in the … Continue reading

Generating a trajectory of quaternions between two given quaternions
First, check my previous post on slerp to learn how to interpolate between two quaternions. In this post, we make a function that uses the previously developed interpolation to generate points (quaternions) between and initial and a final quaternion namely, … Continue reading

Slerp: Spherical linear interpolation in quaternion space
in my previous post, I explained the simple Lerp method for calculating linear interpolation in the quaternion space. I also mentioned that while normalizing the output could help to get an optimized result, the velocity curve is not constant. To … Continue reading
