Public Sub New (position As Point3D, lookDirection As Vector3D, upDirection As Vector3D, fieldOfView As Double)

Parameter

position
Point3D

Point3D, das die Position der Kamera angibt.

lookDirection
Vector3D

Vector3D, das die Richtung der Kameraprojektion angibt.

upDirection
Vector3D

Vector3D, der die Richtung nach oben gemäß der Perspektive des Betrachters angibt.

fieldOfView
Double

Breite des Projektionswinkels der Kamera, angegeben in Grad.
