-## Perspective drawing principles in desmos calculator
+# Perspective principles in desmos calculator
 
-Did you ever wish there was a graphing calculator like desmos's but with 3D capabilities? 
-Well, there is [GeoGebra](https://www.geogebra.org/calculator), but one can do projective geometry in desmos.
+This project originated as a proof of concept for projective geometry in desmos graphing calculator, which does not feature 3D-capabilities by itself. It can be used to understand or demonstrate the principles of pinhole type cameras or perspective drawing techniques. It is not meant to be a full featured 3D-modelling application or raytracer. 
+
+## Features
+* adjustable orientation: focal lenght, shift, height, anzimuth, altitude
+* perspective construction guides: center of view, horizon, station point, ground line, measuring points, horizontal and vertical measuring lines, cone of vision, ground level grid
+* drawing functions: points, polygones, vanishing points, vanishing lines
