Parâmetros

position
Point3D

Point3D que especifica a posição da câmara.

lookDirection
Vector3D

Vector3D que especifica a direção da projeção da câmara.

upDirection
Vector3D

Vector3D que especifica a direção ascendente de acordo com a perspetiva do observador.

fieldOfView
Double

Largura do ângulo de projeção da câmara, especificada em graus.
