DEVICE AND METHOD FOR TRIANGLE DRAWING

摘要

PURPOSE: To plot a triangle at a high speed. CONSTITUTION: A graphics processor consists of an interface 300 which presents triangular fundamental elements which express a graphics image, a triangle interpolation circuit 310 which is connected to the interface 300 and interpolates triangular fundamental elements and calculates plural line fundamental elements from these triangular fundamental elements, and a line plotting circuit 320 which is connected to the triangle interpolation circuit 310 and receives line fundamental element from this circuit 310 and presents picture elements expressing the line fundamental elements during calculation of other line fundamental elements in the triangle interpolation circuit 310.
