I always wondered why 3D points in OpenGL, Direct3D and in general computer graphics were always represented as (x,y,z,w) (i.e. why do we use four dimensions to represent a 3D point, whatâs the w for?). This representation of coordinates with the extra dimension is know as homogeneous coordinates.

Compression fittings work by the compression of an âoliveâ between two tapered surfaces and the pipe itself. The two surfaces are the body of the fitting (be it a valve, connector or any other type) and the nut. Using a spanner and a pair of grips the nut is tightened. This exerts pressure on the olive and bites it onto the pipe. Compression fittings work well if the pipe is clean and cut properly.
