Included files: G_SMITH_TEST3.avi: This is a clip of the scene construction test (T3) being performed in Fully Constrained (FC) mode. G_SMITH_UNCONSTR_T3.avi: This is a clip of the scene construction test (T3) being performed in Unconstrained (UC) mode. This clip was captured using a video camera pointing at the screen. G_SMITH_TEST5.avi: This is a clip of the dual constraint test (T5) being performed in Fully Constrained (FC) mode. Note The way dual constraints are easily broken. G_SMITH_PLAYING.avi: A clip of a sample MIVE session. This clip illustrates collision detection, constraint satisfaction, un-constraining, reconstraining, and negative constraints.
