Camera-to-Screen

PhantomFury shared this feedback 2 years ago
Submitted

I'm pretty sure I'm not the first person to suggest this, so sorry in advance if it is redundant and the answer has already been provided.

What I am suggesting today is a way for camera to link its feed to a the screen, whether it be an LCD panel, control station, or flight seat. That way, it'd allow for features such as a security room where it's full of screens displaying surveillance footage or - what I see as most important - pilot the ship without having to access the camera every time through the UI, as all the footage is already being displayed on the screen (as long as there is power, of course). And if that can be done, it could be extended to the smaller screens in the cockpit so we could have something like a weapons camera. Feedbacks welcome!

It might be done, there is already a mod for that (IIRC it does not work anymore).

But it will decrease the performance of the game - you need to have powerful GPU for that, as each screen is essentially another frame to render. Thus if your FPS is 40, with another camera-on-screen it might drop to 20 (if low FPS was caused by taxed GPU, not overloaded CPU). And it will incur some cost in CPU performance.

But it can be managed: in graphic settings there might be another slider: maximum of camera-to-screens, max distance of player to screen with screens nearer to player taking preference, plus if screen is LOD model it should be ignored.

Two screens showing the input of one camera shouldn't incur double GPU cost - camera should render to buffer and that should be used twice.

And camera displaying screen (with input from any camera) should either show blank screen or screen from frame behind.

The original mod worked fine, almost no performance impact whatsoever. It was well designed, didn't do anything it didn't need to, and used a dynamic pool of your available frames so that it literally couldn't drag your FPS down. The worse your frames, the less the mod did. If you got over 60, it used those for even smoother displays. Xocliw showed it off on the community stream. He showed it directly to Marek, showed it working beautifully, while having none of the drawbacks it was claimed such a mod would have. And then Keen ignored the potential and changed a bunch of things and the mod died.

It did have the drawbacks it was claimed such a mod would have... it's just, it was showcased on powerful computers with enough frames to spare. The second you don't have a powerful computer, you'll see the drawbacks quickly. This is why it wasn't made vanilla.


I dearly wish this wasn't the case because that mod was really cool... but it can't work as anything else than a mod.

Again with the 'can't be done'. I'm reminded of that quote regarding senior scientists saying something can't be done and being most certainly wrong.

Duke Nukem 3d had a camera view to screen feature in a game with user generated maps/layouts 22 years ago. Granted it wasn't 1080p but I don't think anyones expecting that from a Text panel. Unpossible!

From what I can see in the Steam and Keen forums, this mod wouldn't be difficult to implement but suffers greatly from a performance drain. This could be mitigated with a slider on the link controlling frames per second for a capture rate.

Most notably, this would be an excellent feature for Experimental Mode (now that we have it).

Burstar: you forgot that the game is implemented in C#, not in C++ ;-)

And also without memory serialization of objects ...

glad to see this thread bumped i find it ridiculous that this isn't already in the game. Surely you could implement this with some sort of anti-rastorization method where you just don't render the parts of the ship eclipsed by the display just like if you gave dirt or whatever a transparent texture back in minceraft, that's how rodina does it; and even without the fact that this method would be way more efficient, you would also end up with a better, more spacey, implementation 'cause it would have perspective.

@Burstar: from my side that was no excuse, that was explanation.


If different programming tools and approach would be used, game engine would be more effective ... but the development would be slower ...

One thing that would help the framerate is to have the LCD camera view be low framerate itself such as 5 to 20 fps

I was going to sugest the same thingh, glad i searched it first.

If we have cameras and we have LCD panels its only natural to conect the 2.

About the Duke Nukem 3d thing, are you talking about seeing yourself in the bathroom mirror? Because that's actually fake. It's a duplicated room and player model that is displayed with clever rendering tricks.

Also, it's not a matter of C# vs C++. It might be marginally faster if implemented correctly in C++, but it's more a matter of the graphics card having to render 2 "screens" instead of 1.

It's a fantastic feature that i'd love to have, with current technology (Not just SE), it's just not really possible in a way that would be usable in game.

@Domingo yeah I see that now. Apologies I read it wrong :P


@zooltan no, the camera monitors would show a display of the camera view after you look through it. Its framerate was like 1Hz and it only lasted for so long but considering I was playing it on a x486 (I think)...

An option in game settings with sliders to limit darn thing. Probably I would think of getting new computer since cam feedback was so cool back in a day. But I guess it's to much of an effort, shame mod isn't working anymore.

But what if i just REALLY REALLY wanted to build myself a gundam?

To help, you can add this feature BUT calculated only in local when people are near the grid. So it wont use/overload net datas ?

Old mod was great, as long as you didn't have dozens of screens running. IIRC there was a 'performance' slider to make it more user friendly to lower spec machines. If you could at least consider it Keen, that would be great!

While the actual rendering is client side, the camera can be several subgrids - maybe kilometers - away and see a different part of the universe. A camera would be like an additional player, spawning in local asteroids and streaming grid data from the server to be rendered on the remote camera feed. Or cameras are 100% local and intended for cameras in close proximity only, with no load on the server and very low PCU amount. (Maybe have separate server/client PCU?)

Rendering performance impact could be made O(1) by updating a set amount of screens per frame at a preset resolution. I.e. A surveillance room with 10 camera feeds would update every screen at 6 FPS instead of 60, as in this example surveillance camera clip: https://www.youtube.com/watch?v=X2oNWHv0zSQ

Eventually all "extra rendering step" could be queued up so that only one extra rendering is done per frame. I.e. environment cube maps could be on every frame if the queue is unused, but reduce to every second frame if camera feeds are active:

CAM1|ENV|CAM2|ENV|CAM3|ENV|CAM1|...

(Effective frame rate of the three cameras would then be 10 FPS. Camera feeds should only update when the player is actually standing in front of and looking in their direction. Screens being "freshly" activated would take the next slot in the update queue for a max 1 frame delay, unless several screens activated in the same frame.)

Not sure about random LCDs, but I definitely would like to have a feed from camera in my cockpit.

Glass cockpits aren’t worth it on large grids! The glass is far more fragile than heavy armor! I want cameras to be my window to the world and to be sheathed in armor, like ships in The Expanse!


Please, KEEN

Hooo Yes !! make that !

THis is the first fing I was so disapointed when building my first ship in SE :

I saw Camera, LCD, then it was obvious I could link a camera feed to one of cockpit LCD to have a view..... even at low resolution, and even with limitation numbers.


Yes please do that for external LCDs or cockpit LCDs even for one or two feeds that would be awesome.

not mine but just wanted to post it here

i saw this reddit post the other day but it takes a big performance hit.

Keen Support replied to this in an XBox thread;

https://support.keenswh.com/spaceengineers/xbox/topic/lcd-screens-with-live-camera-feeds

Saying that "they will consider this feature".


This current page for PC, was posted way earlier than that post yet, they didn't reply to this one.

Furthermore the discontinued "Live Camera Feeds" mod in this page https://steamcommunity.com/sharedfiles/filedetails/?id=611332581 is filled with people requesting/expecting this feature to be in vanilla since 2016.

Other than possible incapability due to technical difficulties, I really don't understand why developers disregard highly requested features like this and push out totally unrelated content for long periods of time...

In short, as many people out there, I really believe that this should've been in the vanilla game since the LCD's were introduced and also believe that it would elevate the game play so much.
