The crossed grating (20) comprises a plurality of diffractive features (23) arranged along the lines of a first set of parallel lines (25) and along the lines of a second set of parallel lines (26) such that the lines (25) of the first set are parallel to the lines (26) of the second set. The lines of the first set have a first grating period and the lines of the second set have a second grating period. A light beam (B1) coupled into the substrate (7) by the input grating (10) impinges on the crossed grating (20) at a first location (EC1) and further locations (EC2).

Further interactions at second locations (EC2) provide further sub-beams (V₀₁, U₁₀) which propagate in the same direction as the original in-coupled light (B1). Light is subsequently coupled out of the substrate (7) by the output grating (30) to provide a light beam (B2) which is expanded in two directions (SX, SZ) with respect to the beam (B0) impinging on the input grating. A virtual display device (200) may comprise said diffractive beam expander (50).

One embodiment of the present invention sets forth a technique for improving antialiasing quality, while minimizing performance degradation, by adaptively selecting between multisampling and supersampling on a per pixel basis. The resulting performance may be generally comparable to multisampling. At the same time, however, the resulting quality may be generally comparable to supersampling. The antialiasing technique disclosed herein determines whether to use multisampling or supersampling on a particular pixel being rendered, based on the specific coverage of the associated geometry primitive. Because many pixel centers are covered by a geometry primitive, a statistical performance advantage is gained when pixels in a rendered image can be generating using multisampling rather than supersampling. The cases where pixel centers are not covered tend to be less frequent, but are very significant to image quality. High image quality is maintained by rendering these cases using supersampling.
