Variables

A3DVector3dData A3DPDFAnimCameraData.m_sPosition

A3DVector3dData

Camera position.

A3DVector3dData A3DPDFAnimCameraData.m_sTarget

A3DVector3dData

Target position where the camera is looking at.

A3DVector3dData A3DPDFAnimCameraData.m_sUpVector

A3DVector3dData

Camera up vector.

It should be defined so that it is perpendicular to the vector created between the camera and target position. A non-perpendicular up vector results in a view which is tilting when it is activated in the Adobe PDF Reader.

A3DDouble A3DPDFAnimCameraData.m_dZoomFactor

A3DDouble

This parameter is only applicable for orthographic cameras.

It specifies the part of the scene that can be visualized and inversely acts as a zoom factor with the following relationship: [zoomfactor=1/2*view_size], with view_size as the smallest size of the viewable part in the X or Y direction.

A3DPDFEProjectionMode A3DPDFAnimCameraData.m_eMode

A3DPDFEProjectionMode

Camera projection mode: orthographic or perspective.

Assuming that it won’t change during the animation.

A3DDouble A3DPDFAnimCameraData.m_dFieldOfView

A3DDouble

This parameter is only applicable for perspective cameras.

It specifies the field of view as an angle in degrees.
