This section shows how to map the XSI 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 ) / ppheight
Projection 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
