Rongor Posted December 12, 2022 Share Posted December 12, 2022 (edited) I noticed that while using TrackIR, I have to move my head into like 5 inches distance to the HUD frame to have the whole projection becoming visible for me on the HUD glass. If I move my head back into normal position (leaning back to the headrest), the HUD projection size remains unchanged compared to my monitor, yet since the HUD frame size decreases (more distance), only the center content of the HUD projection remains visible. Is this a bug? I don't think this is physically correct. If the distance to the HUD increases, the HUD projection should decrease in size as well...

Snoopy Posted December 12, 2022 Share Posted December 12, 2022 It’s correct, lots of posts within ED’s forums from when it was updated years ago. v303d Fighter Group Discord | Virtual 303d Fighter Group Website | v303rd Fighter Group Twitter Link to comment Share on other sites More sharing options...
Rongor Posted December 12, 2022 Author Share Posted December 12, 2022 how can this work technically? It's like looking on a helmet mounted display, the distance between the projection and my eyes seems ever the same. Yet it isn't. This doesn't make any sense by optical rules. 20221212_212441.mp4 Link to comment Share on other sites More sharing options...

There's a series of lenses that project an image that remains focused at infinity, in the same position and the same size no matter where you move your head. Look up 'optical collimator' for details how Edited December 12, 2022 by jaylw314 4 Link to comment Share on other sites More sharing options...
