A method of rendering a 2-D image includes the steps of analysingsurfaces facing a viewing direction into scanline sequences which represent continuous surfaces, checking depth values of those surfaces relative to a viewing position and discarding without rendering those objects or surfaces lying behind a foremost surface. This has the effect of extending the scanline algorithum to reduce the amount of work managing and processing lists of faces by exploiting the fact that most 3-D scenes are constructed from continuous surfaces made up of adjoining faces.
