Gets a Boolean that specifies if the camera is valid (has TargetViewport3D that has a valid size; has valid values for all properties).
When camera is valid the Point3DTo2D(Point3D) returns correct value; when the camera is not valid, the Point3DTo2D method cannot calculate the 2D screen position.

SyntaxC#
public virtual bool IsValid( bool checkAllProperties = true )
Parameters

Return Value
Booleantrue when camera is valid (has TargetViewport3D that has a valid size)
