What is triangle-coordinates?

This JavaScript snippet defines a custom coordinate system for points inside a triangle, ideal for color pickers or graphics apps needing triangle coordinates area calculations without traditional barycentric sum constraints—t1 and t2 just stay between 0 and 1. It provides forward conversion from any point to these coordinates and inverse mapping back to screen position, using an area of triangle formula coordinates under the hood. Drag points in the live HTML5 canvas demo at tsoding.github.io/triangle-coordinates to see triangle barycentric coordinates in action.

Why is it gaining traction?

Devs grab it for its dead-simple API that skips math headaches in triangle coordinates in computer graphics, unlike heavier libs for triangle mesh or OpenGL triangle rendering. The interactive demo hooks graphics folks instantly, letting them test polar coordinates triangle or triangle grid coordinates on the fly. Ties into niche wins like potential Duffy transform extensions for quadrature.

Who should use this?

Frontend graphics devs building WebGL color pickers or triangle splatting effects. Canvas hackers prototyping Sierpinski triangle generators or triangle arbitrage visualizers. Anyone needing a quick triangle coordinates calculator for education demos like red triangle GitHub education repos.

Verdict

Grab it for prototypes if you're in graphics—19 stars and 1.0% credibility score scream early-stage toy, with thin docs and no tests, but the demo sells the concept fast. Scale up to proper barycentric libs for production.
