<p>A display apparatus for real-time 3-D image synthesis comprises a display processor (28 min ,49) having associated texture memory (41 min ) for storing pyramidal arrays of texture element ("texel") values. Each pyramid array represents a 2-D modulation pattern at several distinct levels of resolution. The apparatus further includes an inter-level interpolator (LINT) for combining data (MOD1 and MOD2) from two levels of the pyramidal array. The texture memory (41 min ) is divided into two banks (TRAM1 and TRAM2) and the apparatus is arranged to store successive levels of a pyramidal array alternately in the first and second banks (TRAM1 and TRAM2) of the texture memory (41 min ) so as to allow parallel readout (at 65A-65D and 67A-67D) of data from any two adjacent levels of the pyramidal array for supply to the inter-level interpolator (LINT). <IMAGE></p> |
