Off Topic / Photogrammetry from video
March 15, 2021, 09:41:54 PM
I was well aware of the concept of using still images of an object, in order to create a 3d model of it in CGI, but I stumbled upon a video on youtube and I think this takes it to a whole new level.
Definitely needs a lot of cleaning up, but even -state of the art- laser scanning requires a tremendous amount of post processing, plus you get all the textures baked in automatically. Have a look:


Copying from the video description:
QuoteI tried to use photogrammetry to create track mod for Assetto Corsa. Result is not perfect, but it is usable. Needs more ironing out.

00:00​ - Comaprison with real footage
01:26​ - One lap racing

The software used is Reality Capture. I recorded video with a gopro mounted on a bike. 4 directions are recorded, forward, backward, left and right. Every 10th frame, or so, is extracted from the videos, not every frame is used. There were about 4.000 images, but with later experiments I realised it could be done with much less. This reconstruction took about 5 days with the manual addition of many control points, and not counting numerous previous failed attempts. It was reconstructed in parts and then they were combined together into one whole track.

So, what do you think? Definitely needs a lot more work to call it perfect, but I think it's very impressive nonetheless. I'm very curious to see if this will catch on and most importantly what it will look like in 5-10 years from now.

Edit: I am in no way affiliate with, or trying to promote any of the software/developers mentioned.

Virtual Reality / Need help/advice from VR users
January 18, 2021, 11:30:57 PM
Hi everyone, it's been a couple of months since I first played GPB, (needless to say I loved it) and I am looking to "upgrade" the experience. The first thing that comes to mind, is getting a VR headset.  I don't know if it gets more immersive than that, with just one piece of gear. It's been almost 15 years since I've played any games (apart from SBK2001 every now and then, and the occasional bikes game demo) so I won't be needing any features that do not apply to GPB. (like moving around untethered etc) With respect to price range, I want to stay below 500-600EUR if possible, as I will be needing a graphics card too.

So, tell me what things I should consider carefully before buying, what are some good options, what things you liked/disliked about your headsets, things you wish you knew before you bought them, what pixel resolution to go for, etc....
What I'm especially interested in, is whether you've had compatibility issues with GPB, e.g. is it likely than any non oculus or htc stuff won't work with GPB?
Also, I am expecting to be able to use 3DOF for "Mouselook/Freelook" and another 2 for rider lean F/B and L/R, directly from the headset obviously. Is that feasible easily through the GPB settings menu? Or do I still have to fiddle with OpenTrack/vJoy and the likes, to get it working?

Also, my crappy 50EUR nVidia Geforce GT710 (2GB) is pushing 70+/-20FPS at 1600x900 at reasonably high settings, with the occasional drop of course to 35-45 in certain spots at some tracks. Given the double overhead that will be required for VR, what graphics cards do you suggest for a smooth ride?

Thanks in advance for any replies.

PS. I didn't know if I should post this in "VR" or "General Discussion", I hope it's ok here.

PS2. Is it possible to get GPB in VR mode to render the two side by side views, if no headset is connected?

General Discussion / How do you find the M2 in beta19?
December 28, 2020, 10:59:33 AM
Hi, all. I wanted to know what you think of the M2 in beta19? I loved that bike since the very first lap (in beta18) because of the very realistic engine sound, its responsiveness and it's character... I mean you had to respect it at all cost, 'cause it wouldn't forgive.
 
However I installed the new beta yesterday and the bike suddenly seems to take all the brake you can throw at it, to the point of disrespect! The grip and braking ability even at the highest lean angles is phenomenal, and it doesn't seem to vary with tyre selection that much. The game even started making screeching noises while cornering at extreme angles, as if it registers contact of some part of the bike with the tarmac. (this happens in Victoria, I haven't played Assen that much, and the other tracks are still downloading.)

I'm not quite sure yet if it's the bike, or some tyre physics update, but when I tried to join a server yesterday I got a data mismatch with the M2, so there must be some changes.

Anyway, I'm sure everyone has noticed this right away, has it affected other bikes too? Do you like it better? And how do you find the changes with respect to the overall realism of the simulation?
