vecPortal

vecPNormal

The current view portal position and normalized direction. This defines the mirror clip plane of the current view.

Algorithm

vecPortal = float4(view.portal_x,view.portal_z,view.portal_y,1.0)
vecPNormal = float4(view.pnormal_x,view.pnormal_z,view.pnormal_y,1.0)

Type

float4

Remarks:

The Y and Z axes of DirectX vectors are swapped due to the Acknex->DirectX coordinate system conversion.
