Moses Turner 8cde257817 aux/math: add vec3 overloads for scalar multiplication 2021-11-29 23:23:57 -06:00
Ryan Pavlik 33c0287f8b xrt: Rename all "num" parameters and fields to "count" (or "capacity" as appropriate) 
This matches the OpenXR usage: the array is the plural of the element type,
and the count is the singular element type plus "count" (usually CountOutput
because of the two-call idiom)

Includes fixes to other code to match API changes.

 2020-10-12 22:13:47 +02:00
Christoph Haag fb71c71a8c xrt: Replace mesh generator with xdev->compute_distortion() 
Each HMD driver now has to implement compute_distortion() which will be called
by the compositor implementation to generate a mesh (usually).

u_distortion_mesh contains implementations for the defaults (panotools, OpenHMD, vive).

Also adds compute_distortion function for Vive distortion

There are differences between OpenHMD and Panotools values, main differences for now:
* psvr has 5 pano coefficients, ohmd has 3
* psvr uses viewport size and lens center in pixels for distortion calculation, ohmd in meter
* psvr uses different distortion scaling than ohmd
