Hi,

We were trying to use VRS helper and Gaze handler to do rendering to HMD.

We noticed NV_VRS_HELPER_ENABLE_PARAMS has an attribute RenderMode,
which can accept Mono, Stereo, Left, Right, but not sure how it works?
Could you tell us which way is right to do the left eye and right eye rendering?

Psudo Code

Method A

send StereoData to gaze handler
updateGazedata
enable VRS_Helper with render mode STEREO

render left eye
render right eye

disable VRS_Helper

Method B

send StereoData to gaze handler
updateGazedata
enable VRS_Helper with render mode Left

render left eye

disable VRS_Helper

enable VRS_Helper with render mode right

render right eye

disable VRS_Helper

p.s.
If Method A is right, how do you know which render buffer is for left eye?
