Apparatus and method for tile binning

摘要

An apparatus and method for tile binning are provided. The tile binning apparatus may include a determination unit to determine whether a triangle obtained as a result of geometric processing includes an abnormal edge, an overlap test unit to perform an overlap test with respect to each edge of the triangle when the abnormal edge is absent from the triangle, and to sort three vertices of the triangle according to Y-axis values and perform the overlap test with respect to each edge of the triangle based on a sorting result when the triangle includes the abnormal edge, and a bin array update unit to update a bin array based on an overlap test result.

1. A tile binning apparatus comprising:
a determination unit configured to determine whether a triangle obtained as a result of geometric processing comprises an abnormal edge, an edge of the triangle being an abnormal edge in response to at least two vertices of a bounding box of the edge of the triangle overlapping respective vertices of a bounding box of the triangle; an overlap test unit configured to
perform an overlap test with respect to each edge of the triangle in response to the triangle being determined to be without the abnormal edge, andsort three vertices of the triangle based on Y-axis values, and perform the overlap test with respect to each edge of the triangle based on a result of the sorting in response to the triangle being determined to comprise the abnormal edge; and a bin array update unit configured to update a bin array based on a result of the overlap.
