(

)

const [virtual, inherited]

Is `this' convex ?.

A polygon is convex if it is planar and if moreover the direction of "turning" at every vertex is the same. This is checked by calculating the cross product of two consecutive edges and verifying that these all have the same direction, i.e., that their pairwise dot products are all nonnegative (which proves the "turning") and equal to the product of their lengths (which proves coplanarity).

set the bounding box to a single point, discarding the old bounding box.

This is a "const" method since the bounding box is a "mutable" data member: calculating the bounding box does not change the object.
