    A response to the 1977 GSPC Core Graphics System



    This paper responds to the 1977 Core Graphics System of SIGGRAPH’s Graphic Standards Planning Committee (GSPC). The authors are interested in low-level device-independent graphics for applications doing data representation and annotation. The level structure and bias in the Core System toward display list processor graphics are criticized. Specific issues discussed include display contexts, attributes, current position, 3-dimensional graphics, area filling, and graphics input.
