Screen tile pair-based binocular rendering pipeline process and method

A screen tile-pair based binocular rendering pipeline process and method, comprising the following steps:

• (1) dividing an entire space into a plurality of screen tile pairs according to the spatial relationship of left and right visual angles in binocular drawing, and generating a primitive list in the input scene corresponding thereto for each screen tile pair;
• (2) after generating the screen tile pairs, obtaining a plurality of spatially consistent surfaces by searching the screen tile pairs, wherein the spatially consistent surface is a surface formed by spaces corresponding to a plurality of connected screen tile pairs;
• and
• (3) after obtaining a plurality of spatial consistency surfaces, scheduling all the screen tile pairs, and simultaneously rasterizing ang drawing the primitives corresponding to each screen tile pair;
• wherein, the specific steps of Step (1) are as follows:
• (1-1) according to a present screen tile size n×n, dividing the screens corresponding to left and right visual angles, respectively, into a plurality of screen tiles Tj0 and Tj1;
• wherein, j=1,2, . . . , N represents the serial number of the screen tiles, and the serial number j is incremented from left to right, from top to small, N is the total number of the screen tiles, 0 represent left in Tj0 and 1 represent right in Tj1;
• (1-2) respectively calculating positions LPi0 and LPi1 of an input i-th primitive Pi projected on the screens corresponding to left and right visual angles, wherein i=1, 2, M, M is the total number of the input primitives, and 0 represent left in LPi0 and 1 represent right in LPi1;
• (1-3) after the positions LPi0 and LPi1 are determined, respectively calculating screen tiles covered by the positions LPi0 and LPi1, and the screen tiles form screen tile set TPi0, and TPi1 covered by the primitive Pi;
• (1-4) in a screen tile unit, according to each polar line in the horizontal direction, simultaneously traversing from left to right the screen tiles on the current polar line in the screens corresponding to left and right visual angles, and determining whether the current primitive Pcur belongs to the currently traversed screen tile pair (Tcur0, Tcur1);
• (1-5) constructing a double-layer index in the traversing process, wherein the first layer index is a primitive index, which is a primitive list on the space corresponding to the screen tiles;
• the second layer index is an index of the primitives on the screen tiles, which is an index list of primitives on the screen tiles corresponding to the corresponding space of the screen tile pairs.
