Vecalc (Vector Calculator) is a little web-based helper for basic vector math.
Release: https://marianpekar.github.io/vecalc/
It takes two vectors on the input (via dat-gui on the top right corner) and computes their addition, subtraction, dot product, cross product, magnitudes of all vectors, the angles among them and also between each axis for each of them as well. The Angles are presented in form of a pair-wise cross table, via dat-gui you can switch between degrees and radians.
All the other outputs are presented in the top left corner. Precision could be set in range from 1 to 3 decimals.
All vectors are visualized in 3D space with axes thanks to THREE.js. In case you want to see normalized versions of these vectors, in dat-gui tick Show Normalized. You can also hide axis by unticking Show Axes
You can rotate and move around using mouse and keys:
- Scroll up/down: zoom in/out
- LMB + Move: rotate
- RMB + Move or arrow keys: traverse
