Constructor Detail

LateralCylinder

public LateralCylinder(double radius,
                       Vect3 bottomCenter,
                       Vect3 topCenter,
                       String texture)

Requires:

radius >= 0 && bottomCenter != null && topCenter != null && !topCenter.equals(bottomCenter) && texture != null

Effects:

creates a cylinder with radius 'radius' bottom center 'bottomCenter' and top center 'topCenter'

LateralCylinder

public LateralCylinder(double radius,
                       Vect3 bottomCenter,
                       Vect3 topCenter)

Requires:

radius >= 0 && bottomCenter != null && topCenter != null && !topCenter.equals(bottomCenter)

Effects:

creates a cylinder with radius 'radius' bottom center 'bottomCenter' and top center 'topCenter'
