VECTORCAMERA

typedef struct tagVECTORCAMERA 
{ 
   L_INT nSize; 
   L_DOUBLE Theta; 
   L_DOUBLE Phi; 
   VECTORPOINT LookAt; 
   L_DOUBLE Distance; 
   L_BOOL bPerspective; 
} VECTORCAMERA,  * pVECTORCAMERA;

The VECTORCAMERA structure holds information about the camera.

Member Description
nSize Size of this structure. Used for versioning.
Theta Rotation angle around the Z axis.
Phi Rotation angle off the Z axis.
LookAt Point on which the camera is focused.
Distance Distance between the camera and the object.
bPerspective Flag that indicates the type of projection. Possible values are:
  Value Meaning
  TRUE Perspective projection is used.
  FALSE Parallel projection is used.

Comments

The camera object is used along with the viewport to project the vector image into a 2D plane.

LVectorBase::SetCamera and LVectorBase::GetCamera are the functions used for manipulating the camera object.

The camera can be used with either 2D or 3D vector images.

pVECTORCAMERA is a pointer to a VECTORCAMERA object.
