Views of Prealbumin with special lenses --------------------------------------- This picture shows pictures viewed from points in the channel of Preambulin. The first picture is viewed from well outside, using a 45 degree fish eye lens. In the next picture, the viewer is just entering the channel, using a 150 degree lens. In the third, the viewer has moved further in, and the lens is extended to 250 degrees. The final view is from the centre of the channel, with a full 360 degree lens. Here are the view setup parts of the WINSOM definitions. Picture 1: PTYPE(2); NPICS(0.13); EYEDIST(1); ZCLIP(-3,1); Picture 2: PTYPE(2); NPICS(0.43); EYEDIST(0); ZCLIP(-2,1); Picture 3: PTYPE(2); NPICS(0.70); EYEDIST(-0.25); ZCLIP(-2,1); Picture 4: PTYPE(2); NPICS(1); EYEDIST(-0.5); PTYPE(2) specifies fisheye style lens. NPICS(1) specifies a full 360 degree, NPICS(x) a 360*x degree lens. EYEDIST(z) specifies a viewing point of (0.5, 0.5, -z). ZCLIP normally specifies front and rear clipping planes. For a fisheye lens, these are clipping spheres: the precise values currently need to be set by trial and error!
