In a pre-launch interview with PlayStation Blog, Insomniac Games has shared few interesting technical information about Spider-Man for PS4, which is finally available starting today.
First of all, director of core Mike Fitzgerald has revealed the exact resolutions of the PS4 Pro version and discussed more openly the way the technical injection technique by Insomniac works on a 4K image.
“On a PS4 Pro, the game outputs to the TV at 4k. Internally, most of the frame is rendered to a 2816×1584 or 2560×1440 image (in expensive situations), then projected over time into the master output 4k image using the “temporal injection” technique (…) to accurately anti-alias the picture,” Fitzgerald said. The resolution on regular PS4 is instead 1080p.
“Temporal injection is a technique we use to create a full 4k image on the PS4 Pro without rendering every pixel on every single frame. We render slightly more than half the pixels, then “inject” them into a full-sized 4k image,” AI Hastings, chief architect added.
“By slightly jittering the locations of the rendered pixels from frame to frame, we can reconstruct a very accurate anti-aliased full 4k image over a handful of frames. There are other teams using similar techniques, but with slight variations in the implementation.”
Also, “the final foe you face in the game is rendered with more than one million polygons—more detail than we’ve ever had for a single character in a game before!”, which is rather amazing for a PlayStation 4 game.
Spider-Man is available now.
