The file designated as "sys_chassis" is a 3D wireframe model of a computer chassis. During the course of the test, the chassis is rotated, panned, zoomed and viewed from different perspectives. The chassis is composed of 6,107 3D solid polylines and 158 3-D dashed polylines. The number of vertices per polyline ranges from two to 11; there is a total of 19,064 vectors. Five hundred (500) frames are displayed in this test.
