This applet is a simple tool for visualizing three dimensional coordinates. Enter comma delimited coordinates for each vertex in the white box, and press enter between vertices.
To view a plane, enter a p followed by A, B, C and D, where ABCD are the coefficients when the plane is written in scalar form (Ax+By+Cz+D=0). e.g. "p1,2,3,-4".
To clear all the shapes press 'c'. Zoom with 'Z' and 'z'.
