hmmm.. well in that case, XP never had a horizontal span either! Extended desktop doesn't merge multiple monitors into one.

evans, thanks for that link. I've never really attempted left foot braking either in real life or in LFS. I never realized the right foot was supposed to remain on the gas.

I always thought it was simply to minimize the transition from braking to acceleration. I never thought about keeping a turbo spooled up, etc.

I'm not sure if the AI cars use the default setup or not, but you can force them to use the same setup as you somewhere in the options. If the AI cars are running faster than you it should be easy to see where you're losing time. If you're running equal times then you're definitely losing speed somewhere as the AI usually takes it easy through chicanes and other places where humans usually go full throttle.

Taylor, nice job. Even if you only dropped a second off of your time, that would put you about midfield in the Road Sport Cup league. Pretty impressive

hyntty, I got your PM. You don't have to worry about your friend Taylor. I'll make sure he's nowhere near the top 10. I'll make it look like an accident by choosing the RAC, muwhahah! Just focus on getting that 1st place. I accept paypal for services rendered.

Quote from kABLiuks :this will be a bit boring race... a very long track... in R7 for me was boring too, because after 4 laps till finish i was driving all alone, so i think it will be the same in R8...

Agreed. I'm looking forward to this combo because I like the cars, but I'm pretty sure it will be boring after the first 1-2 laps.

bah.. not sure why I said that. It was an awful race for me and I really had no chance of winning even if I didn't wreck and spin out 100 times. But I wasn't even planning on entering the race so I guess having an nightmare of a race is better than not racing at all... maybe..

Quote from LiveForBoobs :Yeh i agree. I'm currently using a 15" monitor and 65º degrees of FOV. There's no miracles for small monitors.. i cant put more fov or i cant see note and it all gets distorted. When most ppl can afford 21"++ monitors then id vote, for now i suppose devs have better things to do with their time... unless they they do a quick fix like Juls suggested, which would look exactly the same here, but better for the few ppl that have large monitors. Otherwise, not.

I'm not sure what it's like in portugal, but here you can find a pretty decent used CRT fairly easily. I got a brand new (as in ~3-4 months old) 17" Dell CRT monitor for $15 USD at a garage sale last year.

I felt I could have won that race. I lost focus on the early laps as I was a bit upset after a T1 incident that put me into last place. At that point I just felt like leaving to be honest.

But for remaining 2/3rds of the race I think I was a good amount faster than the rest of the field all the way up to the final lap.

In that case, I don't think it would work at all. After all, with a single monitor we would see the blurry edges in our center of vision and it would just look fake.

As far as the variable FOV, well I kind of feel the same way. Unless you had a large enough display, it think it would just look really bizarre.

Interesting gimpster,

If you had an immersive display, like 3 or 5 monitors or a curved screen, wouldn't there be no need to fake the resolution degradation? After all, since the leftmost and rightmost parts of the immersive display are in your peripheral vision, they are already degraded!

Quote from J@tko :+75 million.

Especially those who ask 'how much fuel for the race?'
  1. Do it beforehand
  2. It takes some very simple maths.

haha. well I'm guilty of the fuel bit because I stopped attempting to do simple math after I got my college degree i didn't think people cared about that!

Quote from tristancliffe :This is a great, cheap little addition to a road seat belt, that will help you drive.

http://www.demon-tweeks.co.uk/ ... SPORT&pcode=CGLCGLOCK

I had one in my last car. To be honest, I didn't like it. For a street car, it weighs down the seat belt (so you have to manually retract it), it sometimes would dig into me, and on summer days (in a convertible) it would heat up like crazy just like those good old metal seat belts.

Quote from J@tko :I have to say I'm guilty of piking other people's sets!

Haha. Well I didn't mean I was against sharing sets... I just think it's more proper to ask for sets in a practice session or in the forums "before" the race is about to start.

Quote from tristancliffe :
You never ever have to support yourself. If you do, then your seat is not only inadequate, it's unsafe. Get yourself a proper harness (or even a road belt properly tightened), pad the seat in the right place (costs nothing, and takes no time). If you are using your elbows to support yourself you can't steer properly. If you are using your knees to support yourself you can't use the pedals properly. There is no excuse for anyone on a track to ever have to support themselves, so I don't buy that at all.

I don't understand why manufacturers can't use properly bolstered seats in the first place. People who ride in my car always love how the seats "hold you in". When I explain to them that the seats don't hold you in for sh*t and I have the dents in the speaker panels to prove it they look at me all confused...

Quote from Marlbro :Before I bought a licence for LFS I ran quite a lot of laps on BL in the FBM.
I couldn't imagine how the racers on there were getting the times they did...even though I practiced a lot I was way off.
I asked a fellow demo racer for his setup and within 2 laps I had cut nearly 4 seconds off my lap time, it made that much difference.
It was this that helped me make the decision to buy the licence.
I thought I could now run with the big boys. It might make the difference of 2 seconds or 0.2 but it makes the driver think wow I CAN do this, it might be the difference between showing up for a race and not. There is nothing worse than struggling at the back with no clue how to fix it...I know.

I think the big difference here is you were trying hard to get better. Some people just show up before the race and ask for sets! I don't mind sharing sets with people who are working hard for it. Still, with the exception of the last race, which I put alot of work into, I've been using default sets with little practice and have been running midpack?

Quote from Juls :Paper from microsoft research. They start from a wide FOV camera picture showing a conference room. This picture has all characteristics of wide FOV game view: far objects too small, objects on the sides stretched.
And they apply a distorsion directly on the picture, stretching the center and shrinking the sides, to obtain a better picture.

http://research.microsoft.com/~zliu/TR-2002-110.pdf

Real-time display warping software using a customizable grid/map, done to adjust projection to a curved display, but similar technique can be used to apply distorsion described in the previous document to get a better picture on a flat screen.
http://www.youtube.com/watch?v=7wkp9GhUp58

Juls, I have not finished reading the article, but look at the end of the first section:

Quote :
Since the warping function do not scale all parts of the image the same, the resulting warped images have very uneven resolution. For video conferencing applications, some regions may be zoomed up significantly resulting in poor image quality. To address this problem, we have constructed a new five-lens camera, each with a different field of view to obtain more uniform resolution after the application of our warping functions. We demonstrate real-time capture, stitching, and warping of the pixels from the five-camera array.

I'll have to read the rest of the article. But it appears they still need to take different "views" and stitch them together in order to generate the final image.

Quote from Marlbro :Yeah maybe not exactly that answer...but I have seen MANY requests blanked...
I've also seen on these very forums people sharing setups "but it's not my real race setup" why?
Maybe sharing should be compulsory. I understand the desire to win but we are supposed to be a community and like has been said before, you might not like the setup but somthing in it might help your setups.

To be honest, atleast in this league it really doesn't matter if you're using a good setup. A good setup won't help you become a better driver, which is the real goal of the LFSBC. You can only become a better driver through practice.

In round 5, I qualified 9th out of 18 with an hour of practice on race day using the default race_s FOX setup. If I had practiced a full week on the default setup I would guess I might be able to drop my time a full second or so. That would have put me near the top in qualifying times...

The people usually asking for sets are those who show up right before the race is about to start with no practice! The right setup isn't magically going to allow them to run with the leaders....

Quote from Juls :You lose some detail in the center because you stretch it a bit, and you get more detail on the sides because they are compressed.
But before distorsion you have to render a full display frame...so for example 4800*1200 for three screens....not 1600x1200.
In order to be sure to have no details lost, the frame rendered before distorsion should be a bit larger than display.

Anyway, if two guys agree to give you their license ID/password for a test you can try to run three LFSs in windowed mode, one per screen. Two as spectators in your car with rotated views, and you play with middle LFS...it should work no?

I was actually thinking of doing that. I have two computers here. All I would have to do is install it on the other and watch the same replay on both machines.

Edit: That didn't work so well. I expected my work laptop to run LFS pretty bad since it's a pentium m 1.6ghz with onboard video. But I didn't think I would only get 10FPS at 640x480 16bit oh well.

Quote from vixer :Demo racer :-), are there skidmarks on Blackwood ? I mean skidmarks that dont disappear.

Technique did you think bout making a Freetrack ? You can make a real TrackIr 4pro (if ur screens refresh is lower then 90hz) for +/- 100$ out of a Philips SPC 900 NC (90 FPS camera) .

Freetrack or TrackIr is not necessary if you have an immersive display. I've never used either, but even my 20.1" screens seem to be large enough to give you a fairly immersive environment. There's a review on the TrackIR on SimRacingTonight.com - look in the archives section. I don't recall which episode it was.

Quote from Juls :Anyway, what you did here is a distorsion. You stretched left and right view in order to show what gives a 3 monitors surround display on a simple flat picture. This is the general idea of this thread...show on a flat picture what you see on a spherical display. Or ask the game to produce the right picture for 3 screens with 45 degrees angle between each. That is the same kind of thing....

There are for the moment four ways to do it:
* vertex shader as mentionned before. Discarded because of artefacts.
*multiple viewports (from directx9 with swapchains, should make the game slower and cause GUI problems)
* pixel shader as a post-process effect
* projection of the frame on a stretched grid

After, it is a matter of rendering speed. According to graphic adapter architecture, the shaders/projection should be a lot faster than the multiple viewport. But I am not sure.

When you take a 135 degrees view, the three 45 degrees viewports views are already inside! You just need a little distorsion to get them, and prepare the same view as in your previous post. It is faster I suppose than asking the game to render three viewports.

You seem to know much more about this then I do, so I'm not doubting you. Yeah the 3 views are inside, but with post processing, aren't you losing all the detail since you have to "stretch" some parts of the image? Now that I think about it, yes you must. If you render one view, lets say 1600x1200 and split it across three - you only have 1600 pixels of detail, except some areas are stretched to make it look correct, right?

Quote :

I'm not familiar with DX9 at all, but one thing to note is LFS development doesn't move as fast as hardware development. I think the video cards of tomorrow will certainly would have no problem with this. They've had multiple viewports in flight sims for a long time, right? Also, it won't be long before we're flooded with Alienware style triple monitors with no borders!

Quote from vixer :Technique I think u should turn ur FOV a bit down. Or not ?

And skidmarks ? Lots of them and cracks and other litle stuff ?

Hi Vixer, when the left and center viewports are viewed on my 2 monitors with the left monitor angled 45 degrees the FOV looks very realistic. My eyes are centered on the center monitor and I have to turn my head to see the left monitor (I'm sitting a little more than a 1' away from my center monitor). It doesn't look correct when you zoom out is shown in your picture. Also, you may have misunderstood my post. My center monitor FOV is only 45 degrees. However, the improvement suggestion is to allow multiple viewports. Thus, the left and right monitors have a FOV of 45 degrees as well bringing the total combined FOV to 135. This is different than what we currently have: 1 viewport with 135 degree FOV. See shotglass's post (#74) to see what it would look like with 1 viewport. Remember, humans can see ~180 degrees. Since 3 monitors can't provide a full wrap around 180 view, I think 135 is a fairly reasonable FOV.

As far as those graphical glitches, ask the devs! You can see this yourself. Load up a track with FBM, set your FOV to 45 degrees and rotate the camera about the vertical axis -45 or +45 degrees.

As far as skidmarks what do you mean? We already have skidmarks in the game.

I only used Photoshop's Transform - Perspective so you guys can see that when the monitors are angled towards the user at 45 degrees everything lines up nicely.

There doesn't appear to be any need to distort the left and right views at all. If you have 3 monitors you can try it out yourself. In the photo I took, those are just raw screenshots from LFS with no modification.

Here's 3 raw screenshots (no modifications) that I applied to three 4:3 polygons in a 3D modeler. The left and right rectangles were angled pricely 45 degrees towards the user.
