Yep, they key is to thrash the mods and get them out quickly.

If you don't like it, then it might be an idea to not look through other people's mods. Simple solution :up:.

I see you have been removing some of your more obnoxious posts from the forum, well done :yeah:.

Is that black area still able to display contacts?

Nisgeis 04-26-09 05:35 PM

Well, reading between the lines...

Are you returning black instead of the radar screen texture to remove the default bearing numbers?

Hitman 04-27-09 02:38 AM

Isn't the black area simply an alpha channel mask? I did it with good results as seen in the screens I posted above :hmmm:

Anvart 04-27-09 02:49 AM

No ...
But ...
You have made all correctly! :up:

My pic's ... are entertainment only ... :oops:

Wouldn't it be better to have the whole PPI screen display targets, rather than blanking off a section?

To blank a small section has both the utility of hiding the waful encoded numbers and also allwoing to give the radar display the exact look it had, with a bearings ring on the outside. I had already planned changing the distance display in the obj or sim file to ensure that you would still see on the visible part the maximum distance intended. And since we can place the camera closer, you won't have any problem in seeing the details accurately. :up:

Why not just remove the numbers and still use the full amount of the display, so the targets displayed under the new numbers? As an aside, as far as I know, the bearings weren't shown on the actual display in the SJ sets. I think they were on the wheel that rotated the head round.

I don't think that setting has any effect on the PPI scope, only the 'A' scope.

Nope, that doesn't work, have already tried.

Because the real SJ displays actually had that dead zone on the border of the screen, a rim with the bearing numbers.

No, no, they were there. Look closely at this pic (it has the numbers in an outside ring each 30 degrees)

Nisgeis 04-27-09 01:24 PM

Wow, they're tiny :) and that border is very small. No wonder I never noticed before - That looks like the USS Cobia's set?

Hitman 04-27-09 02:37 PM

Yes, it's the USS Cobia SJ PPI display :up:

And this is the mask overlay I have prepared for it, when the mod is finished :D

Now that is a PPI display! Good job on that!

EDIT: the only thing that I can bring up is the orientation of the bearing numbers. This illustration of the SC/SK radar from the 1945 Radar Operator's Manual shows the bearing numbers oriented slightly different:

Now, it may be that you have other detailed images of the SJ-1 PPI that confirm it's correct as it is now. Just thought I'd bring this up, nonetheless.

Nisgeis 04-28-09 06:43 AM

The radar manual for the SJ set talks about drawing on bearing lines and range rings with a grease pencil, so it seems unlikely that it was an original feature to have the bearing lines on the scope. The accurate bearing graduations were on the wheel, marked in quarter degrees. But it doesn't really matter - the in game set doesn't allow accurate ranges on multiple targets, so we'll have to make it the best we can with what there is to work with.

Thanks Luke, I had that picture but after digging around, it seems that radar wasn't ever installed in fleet boats. I have however pictures of late war models of the SJ display, which seems to have evolved considerably. In the Batfish it even included rotable ring linked to the compass repeater which showed at the same time true and relative bearings to the target, as well as very detailed bearing lines for precision (This pic was posted here long ago by someone I can't remember now, many thanks in any case to him for sharing):

It probably wasn't in the first models, however it might have been in later ones. The picture I showed above of the USS cobia radar shows not just drawn lines, but also lines that are evidently in 3D, i.e. there is some kind of dent or engraved channel in the glass that will later light up when the radar is switched on.

Take a look at this second picture of the PPI of an SJ radar, but switched off:

These lines that show there are evidently different, not in 3D but instead draw on the glass. But the display on the Cobia looks like the one from Batfish above, the lines are tiny glass tubes. :hmmm:

Nisgeis 04-28-09 03:07 PM

Got a spare bit of time and here is the new shader with a simple sample grid, ready to be drawn on however Hitman sees fit.

COOL :yeah:

Will test and report :salute::ping:
