An illumination device is composed by arranging a shutter member on a light emitting side of an LED light source, capable of changing a condition of light illuminating the outside when a position or the shutter member is changed by slide or rotation. The compounds are useful for treating disorders, particularly cell proliferation disorders, including cancers, inflammatory and neurodegenerative disorders; and inflammation associated with infection and cachexia. The techniques feature an energy minimization scheme in which distances between points on the surface of the three-dimensional virtual object serve as set lengths for springs connecting points of a planar mesh.
