DESCRIPTION

RiThinLensCamera( const RiVector3 &lCenter, const RiONB3 &uvw, RiReal distanceToFoc, const RiVector2 &uvmin, const RiVector2 &uvmax, RiReal lensDiam , RiReal front );

lCenter lens

center (eye point)

uvw the

ONB, where V is the up-vector and W points opposite the view-plane normal (towards the eye)

distanceToFoc is

the distance to the plane where objects are in focus

uvmin,uvmax are

the bounds of the image in the plane of focus.

lensDiam is

the diameter of the lens.

    RiThinLensCamera( const RiVector3 &lCenter,  const RiONB3 &uvw,   RiReal distanceToFoc,
		      const RiVector2 &uvmin, const RiVector2 &uvmax, RiReal lensDiam = 0, RiReal front = 0);

lCenter eye

point or center of the lens

lookAt Point

being looked at. Defines the distance to focal plane

fovDeg Total

viewing angle in degrees for the width of the film plane.

aspectRation ratio

of width to height

lensDiam The

diameter of the lens

front Distance

to front clipping plane

		     RiReal fovDeg = 45, RiReal aspectRatio = 1.0,
		     RiReal lensDiam = 0.0, RiReal front = 0.0);

lCenter

eye point or center of the lens

uvw

the ONB, where V is the up-vector and W points opposite the view-plane normal (towards the eye)

distanceToFoc

is the distance to the plane where objects are in focus

focalLength

focalLength of lens

fnumber

Ratio of focal-length to the diameter of the lens

wfilm,hfilm

width and height of film

cxfilm,cyfilm

offset of optical axis from film center (0.2,0.3) would

front

Distance to front clipping plane be to the right and up in the final viewed picture
