Z-buffer

Z-buffer

(graphics)
An array used to store the maximum Z coordinate of any feature plotted at a given (X, Y) location on the screen, used for hidden line removal in a 2D rendering of a 3D scene. The Z axis is perpendicular to the screen with values increasing toward the viewer so that any point whose Z coordinate is less than the corresponding Z-buffer value will be hidden behind some feature which has already been plotted.

Given that my colleagues and I worked on this problem for multiple years, which is not uncommon in industry, it was entirely acceptable to design and implement a domain-specific planner that uses fast C-implementations for required set operations, the z-buffer algorithm (Rossignac and Requicha 1986) for geometric reasoning, and intelligent precomputation of action effects where possible.
