The Angles are presented in form of a pair-wise cross table, via dat-gui you can switch between **degrees and radians**.\n\nAll the other outputs are presented in the top left corner. Precision could be set in range from 1 to 3 decimals.\n\nAll 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**\n\n## Orbit Controlls\n\nYou can **rotate and move around** using mouse and keys:\n\n- Scroll up/down: zoom in/out\n- LMB + Move: rotate\n- RMB + Move or arrow keys: traverse\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmarianpekar%2Fvecalc","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmarianpekar%2Fvecalc","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmarianpekar%2Fvecalc/lists"}
