Spheres and Barrels

A sphere is defined using the keyword SPHE along with a center point, radius and rendering accuracy. In the case of the sphere, this represents the number of edges from pole to pole:

   SPHE <x> <y> <z> <radius> [<sides>]

Example

   SPHE 125.0 2035.0 -50.0 375.0 32

A barrel is used as a more precise way to model a solder ball that has been reflowed; during the reflow process the ball partially melts and squashes down. The parameters used are consistent with Optimal's model parameters.

BARL <x> <y> <z> <radius> <r_upper> <r_lower>  [<sides>]

Example

 BARL 125.0 2035.0 -50.0 375.0  275.0 275.0  12
