PEP_structVIEWINGAT

Purpose

When RenderEngine is Direct3D for the Pe3do control, this property is used to set the camera's focal location in data units with respect to X Y Z data. The DegreeOfRotation and DxZoom will be based on this focal location unless ViewingFrom is non zero.  

To set the location, initialize a POINT3D structure with the location and set with PEvset. To get the location, call PEvget with destination buffer as address to a POINT3D struct.

The POINT3D structure is simply 3 float's.

typedef struct { float X; float Y; float Z; } POINT3D;
