Must be drawn to give the impression of uniform illumination. Vector graphics displays were therefore best suited to the depiction of wireframe images in which there was no necessity to depict filled geometric shapes. 23. There is a one-to-one mapping between screen pixels and video memory (RAM) and by changing the contents of a memory location, an appropriate visible change can be produced in the corresponding pixel. 23 (in which for convenience we conceptualise the video memory as a 2-D array) modifying the contents of memory location ‘A’ will, when the display is refreshed, directly impact on the visual properties of pixel ‘A’ – and will effect no other pixels.

E. somewhat lower than the demands placed on the graphics engine by the need to ensure 30 An Introduction to Computer Graphics and Creative 3-D Environments that images depicted on a display that exhibits TLO are both consciously and subconsciously perceived as being flicker free. We will use the terms ‘image refresh frequency’ and ‘image update frequency’ as follows: Image Refresh Frequency (fr ): The frequency at which images must be written to a display that exhibits TLO so as to ensure that both conscious and subliminal flicker are avoided.
