Abstract
A pick correlation method, comprises the steps of displaying a pick marker on a display screen; directing the pick marker at an image on the display screen, the image comprising at least one line primitive, and the pick marker having a pick window corresponding thereto; subjecting the at least one line primitive to a trivial test, whereby the at least one line primitive can be trivially tested by the trivial test if the at least one line primitive has both of its end-points outside of the same extended edge of the rectangular shaped pick window and, if successfully tested by the trivial test, accepting or rejecting the at least one line primitive in accordance with the results of the trivial test; and if the at least one line primitive cannot be trivially tested, subjecting the at least one line primitive to a non-trivial test which does not require performing floating point operations, and accepting or rejecting the at least one line primitive in accordance with the results of the non-trivial test.
