trickIR5 issue with F-15C hud

[happy cavin]

TRICKIR5, flying f-15c,

 

when i am getting close to the hud or getting far from the hud,

 

the hud display does not change.

 

see the attachments.

 

how to fix it?

 

thank you.

There's no fix, this is the way it's supposed to work.

To perhaps elaborate:

 

HUDs are collimated to infinity; that is, no matter the range you look at them from, they will display the exact same information relative to the terrain/airspace ahead of you. If you move your head a far way back, in order to relay the correct information relating to what's "on the other side" (ie. real airspace), you'll end up with not all of the HUD symbology being visible.

 

This is as in reality.

 

What you are seeing is not only "as in real aircraft", it is actually "as a HUD must work to be useful at all". To understand it, remember that the HUD is there to make symbols appear exactly on objects you might not see with your own eyes; the "boxes" indicating radar contacts must exactly enclose where the target contact actually really is. If it didn't do that, you might as well not have a HUD and just use the normal radar scope. (Or, for gunfire, regular crosshair.)

but ,when fly su27, it works well.

[GGTharos]

Then the HUD is not correctly implemented in su27.

[Irregular programming]

It's the su27 that's broken, or not updated yet.

[flashben]

Su-27 HUD works fine. In the F-15C cockpit the trackir Z-axis is bound to head moving forward or backwards. In the Su-27 this could be binded to zoom in which it looks like the HUD changes size.

[Zabuzard]

As said theres a difference between zooming in and moving the head forwards, check your axis binding in the settings for that. First one will zoom the whole picture including the HUD, second one will not zoom the HUD like in reality :]
