Transformation functions GDDM-GKS V1R1 Programming Guide and Reference SC33-0334-00 |
|
GKS transformation functions are provided to allow mapping between the three coordinate systems, world coordinates (WC), device coordinates (DC), and normalized device coordinates (NDC). There are three types of transformations; each involves a different combination of coordinate planes. Normalization transformations map WC to NDC. Workstation transformations map NDC to DC. Segment transformations map geometric primitives from NDC to NDC. (For more information about segment transformations, see "Segment functions" later in this topic.) Subtopics: |
