Here’s a some screenshots of\u00a0OculusWorldDemo, showing\u00a0a bit of how the post-render, pre-warp shaders interact with FOV and IPD — and the larger system that the functions I’ve been hijacking are meant to be a part of.<\/p>\n

(Note:\u00a0the demo was targeting the\u00a0DK1)<\/p>\n

The defaults:<\/p>\n

\"defaults\"<\/a><\/p>\n

With “zero IPD” toggled:<\/p>\n

\"zero<\/a><\/p>\n

Max FOV at 45.4 degrees (can’t go lower than\u00a020, which is similar):<\/p>\n

\"max<\/a><\/p>\n

Max FOV at 130 degrees (it goes higher, but you see no change):<\/p>\n

\"max<\/a><\/p>\n

 <\/p>\n

These are just the things easily exposed in the demo’s menu; they don’t do exactly what we’d want to test.<\/p>\n

“Zero IPD” is described as:<\/p>\n

 \/\/ ForceZeroIpd does three things:\r\n \/\/ 1) Sets FOV to maximum symmetrical FOV based on both eyes\r\n \/\/ 2) Sets eye ViewAdjust values to 0.0 (effective IPD == 0)\r\n \/\/ 3) Uses only the Left texture for rendering.<\/pre>\n
So that’s about what we’d expect to see.<\/p>\n
Max FOV is used similarly to the clamping function mentioned in earlier posts, and is an FovPort;\u00a0it looks here that\u00a0FovPorts may have more viewport to them, than FOV.<\/p>\n","protected":false},"excerpt":{"rendered":"
