In this video, I continue working on Engine Simulator, pushing the fluid simulation to its performance limits with 4 cylinder engines.

the sound at 15:46 is absolutely insane
-
Engine go vroom vroom am I right 😁
-
that wobble sounds perfectly reasonable and realistic, it's probably a bad exhaust design and not a simulation issue
-
17:41 POV: You lost GPS acces and went too far off into the texan countryside when you hear a tuned tracker from behind start to overtake you lmao
-
Hell yeah, man's been cooking.
-
Holyyyyy the pull at 15:46 gave me chills
-
I legitimately predict this will in some way shape or form find its way into almost every video game with vehicles in the near future
-
oh dude, the audio is sounding so awesome now! Your progress feels hard earned, and is showing fantastic results
-
I was one of the people who was a little disappointed at the single cylinder sound. This completely obliterated any concerns I had back then. Honestly this already sounds absolutely amazing, especially the comparison with the unprocessed sound from ES2D shows how far this project has come. This completely restored my faith and I will worship at the altar of Tubular until this gets released!
-
15:45 Jesus christ this sound is insane! I think I just had a eargasm
-
The audio at 15:50 literally gave me goosebumps. This is the future of racing video games, sim and arcade. You deserve millions for this masterpiece of coding. You've done it, minus a few tweaks you said yourself you want to do, and with another head or two on the project in the future, you are well on your way to making some SERIOUS cash renting this software to big corporations for both fluid simulation purposes and game dev. You are brilliant.
-
Everyone is saying this, and i'll say it again, the sound at 15:46 is CRAZY. I cant wait for more updates, this is looking incredible.
-
17:43 straight up sounds like a tractor to me
-
19:20 actually sounds like my miata with the muffler delete
-
The trick to having multiple things operating on a single state is to double-buffer it so that CPU is reading from previous frame's output, and GPU is rendering with it, while CPU (or whatever device is performing the simulation step) outputs the simulation increment to a back buffer. Then you swap the buffers' roles. I'm sure you're well aware of double buffering, but sometimes we forget things!
-
If I'm not mistaken, the wobbling you spoke about at 15:46 is a result of exhaust air resonating in the system. I think that sound happens irl too with some exhaust systems. You'll of course want to check and verify but if it is because of a physical property and not an issue with the sim, it means you're doing very good with the exhaust side of the simulation
-
ES3D sounds so much better than 2D, I cannot wait until I can play with this
-
The smile I had on my face after hearing the acceleration through the gears and that growl at 15:48 Excited for the future where we can test and hear the differences in exhaust layout for different engines. Imagine being able to find a good sounding exhaust for the S55 by building the engine and exhaust in this simulator and figuring out what makes it work digitally first
-
I had no idea anyone complained about the new version sounding less realistic, and I'm giggling now because OF COURSE it initially sounded less realistic, it was really early in development. It's STILL really early but SO GOOD.
