A STARTING POINT, MADE FOR YOU
The geometry sketcher
toolbox.
Transform point sets, inspect intersections and export coordinate sketches.
INSIDE THE TOOLBOX
Starter collection8 useful places to start.
These tools use Cartesian coordinates and explicitly stated floating-point tolerances.
Convex hull builder
Find and plot the outer boundary of a point cloud.
Polygon centroid calculator
Locate the uniform-area centre of a simple polygon and plot it.
Point-in-polygon checker
Test whether a point lies inside, outside or on the edge of a polygon.
Line segment intersection
Find a crossing point or collinear overlap between two finite segments.
Circle intersection points
Find the intersection coordinates of two circles and view their geometry.
Triangle centres from coordinates
Plot the centroid, incentre, circumcentre, orthocentre and nine-point centre.
2D point transformation
Scale, rotate and translate a point set with a comparison plot and CSV export.
Bézier curve sampler
Turn control points into an exportable curve and inspect the control polygon.
