ProjectionPlane#

This projection method is based on providing three corner points that are used to construct a virtual image plane. The units of the positions are all relative to the user’s position so are ultimately arbitrary.

  • type
    string = “ProjectionPlane”

    Defines the type of this projection.

  • lowerleft
    vec3

    The position of the lower left corner of the projection plane relative to the User’s position. The units for these values are arbitrary.

  • upperleft
    vec3

    The position of the upper left corner of the projection plane relative to the User’s position. The units for these values are arbitrary.

  • upperright
    vec3

    The position of the upper right corner of the projection plane relative to the User’s position. The units for these values are arbitrary.
