◆ RevSurfaceForm() [1/2]

ON_RevSurface* ON_Sphere::RevSurfaceForm ( bool  bArcLengthParameterization,

) const

Description: Creates a surface of revolution definition of the sphere. Parameters: bArcLengthParameterization - [in] true: The domain will be set to (0,radius*2*pi)x(-radius*pi/2,radius*pi/2) false: The domain will be set to (0,2*pi)x(-pi/2,pi/2) srf - [in] if not nullptr, then this srf is used. Result: A surface of revolution or nullptr if the sphere is not valid.
