Constructor & Destructor Documentation

openvdb::OPENVDB_VERSION_NAME::tools::PerspectiveCamera::PerspectiveCamera	(	Film &	film,
		const Vec3R &	rotation = `Vec3R(0.0)`,
		const Vec3R &	translation = `Vec3R(0.0)`,
		double	focalLength = `50.0`,

Constructor.

Parameters

film	film (i.e. image) defining the pixel resolution
rotation	rotation in degrees of the camera in world space (applied in x, y, z order)
translation	translation of the camera in world-space units, applied after rotation
focalLength	focal length of the camera in mm (the default of 50mm corresponds to Houdini's default camera)
aperture	width in mm of the frame, i.e., the visible field (the default 41.2136 mm corresponds to Houdini's default camera)
nearPlane	depth of the near clipping plane in world-space units
farPlane	depth of the far clipping plane in world-space units

If no rotation or translation is provided, the camera is placed at (0,0,0) in world space and points in the direction of the negative z axis.
