Projecting a Point onto a Plane This is done in a series of small steps; Defining an Arbitrary point on the plane Creating a Vector from the point to be…Continue readingProjecting a Point onto a Plane

Points are defined by three values of magnitude X, Y, Z for example 100mm, 240mm, 345mm. They maybe the simplest geometry form but points are the underpinning geometry for everything…Continue readingPoints

Planes A plane is really two points, one that defines a vector(ok I’m cheating, one of the points for the vector is always at 0, 0, 0) and a point…Continue readingPlanes

Vectors Vectors, Magnitude and Unit Vectors A vector is simply a line from point to point, the length of the line is unitless so its not defined by mm, m…Continue readingVectors
