This section shows how to map the Softimage camera settings to the corresponding mental ray settings.
Projection plane on:
// Convert from inches to cm (Softimage units)
ppwidth = 2.54 * cam.projplanewidth
ppheight = 2.54 * cam.projplaneheight
ppoffsetx = 2.54 * cam.projplaneoffx
ppoffsety = 2.54 * cam.projplaneoffy
mr.aspect = cam.projplanewidth / cam.projplaneheight
mr.aperture = cam.focal * ( cam.projplanewidth / projplanedist )
mr.x_offset = ( render_res.x * ppoffsetx ) / ppwidth
mr.y_offset = ( render_res.y * ppoffsety ) / ppheightProjection plane off:
mr.aspect = cam.aspect mr.aperture = cam.aperture mr.x_offset = mr.y_offset = 0
Orthographic off:
mr.orthographic = miFALSE mr.focal = cam.focal
Orthographic on:
mr.orthographic = miTRUE mr.focal = 1.0
