Constructor & Destructor Documentation

CameraUtilScreenWindowParameters()

CAMERAUTIL_API CameraUtilScreenWindowParameters	(	const GfCamera &	camera,
		GfCamera::FOVDirection	fitDirection = GfCamera::FOVHorizontal
	)

Constructs screenwindow parameter.

The optional fitDirection indicates in which direction the screenwindow will have length 2.

Member Function Documentation

GetFieldOfView()

double GetFieldOfView ( ) const

inline

The field of view.

More precisely, the full angle perspective field of view (in degrees) between screen space coordinates (-1,0) and (1,0). Give these parameters to RiProjection as parameter after "perspective".

Definition at line 42 of file screenWindowParameters.h.

GetScreenWindow()

const GfVec4d & GetScreenWindow ( ) const

inline

The vector (left, right, bottom, top) defining the rectangle in the image plane.

Give these parameters to RiScreenWindow.

Definition at line 35 of file screenWindowParameters.h.

GetZFacingViewMatrix()

const GfMatrix4d & GetZFacingViewMatrix ( ) const

inline

Returns the inverse of the transform for a camera that is y-Up and z-facing (vs the OpenGL camera that is (-z)-facing).

Write this transform with RiConcatTransform before RiWorldBegin.
