Retrieves the camera's projection matrix. The projection matrix used for rendering always has its far plane set to infinity. This is why it may differ from the matrix set through setProjection() or setLensProjection().

scaling

val Camera.scaling: Float4

Returns the scaling amount used to scale the projection matrix.

size

val Viewport.size: Float2

upDirection

val Camera.upDirection: Direction

Retrieves the camera up unit vector in world space, that is a unit vector that points up with respect to the camera.

viewTransform

val Camera.viewTransform: Transform

Retrieves the camera's view matrix. The view matrix is the inverse of the model matrix.
