Detailed Description

Drawing a figure, made of lego block, using ROOT geometry class.

Reviewed by Sunman Kim (sunma.nosp@m.n98@.nosp@m.hanma.nosp@m.il.n.nosp@m.et) Supervisor: Prof. Inkyu Park (icpar.nosp@m.k@ph.nosp@m.ysics.nosp@m..uos.nosp@m..ac.k.nosp@m.r)

How to run: .x lego.C in ROOT terminal, then use OpenGL

This macro was created for the evaluation of Computational Physics course in 2006. We thank to Prof. Inkyu Park for his special lecture on ROOT and to all of ROOT team
