Status on Core 300 vehicles

[Crashy]

Hi,

I would like to know what's the status for the raycast vehicles implementation in core 300? The demos are deactivated for now but what is the amount of work to get them working?

I could help if help is needed.

Thanks.

I tell you what I will start the vehicle tonight.
You say you want to contribute, what do you have in mind.
I am planing a very, very high quality vehicle mroe on the reaslistic side tham on the arcade side.

I will make a not branch for do that, because the bug can take a long time and they do not promote the engien as much as the vehicles.

I should have helped if the work on vehicles were minor modifications to the actual base, to make you gain some time.

However , if you have a precise plan or a todo-list of what you want to do, I could of course help you:)

I would like to add another vote on this request.

I would like to make a game with good vehicle physics and also networked, I have a prototype with 1.53 working. To be able to network it properly, I can't use Newton 1.53 (the last version with a proper C API for vehicles as far as I know, I don't want the C++ API, as I'm not using C++ and I don't want to write a wrapper myself).

Ok I will make the car funtional these hollidays, starting thes weekend.

Hey Julio,

Any progress on the vehicles?

Remi.

[Julio Jerez]

if you are still interested.
I am on the vehicle again.
I just checked in the working version and I will spend some time this week make more adjustments.

Oh neat, I will definitely make use of these.

Hi Julio,

I have tested a vehicle demo and it works in a very strange way on my workstation (Win7 64bit, Core I7-3930K, 16 Gb RAM) - http://youtu.be/afKhWy_3nn0
When I'm pressing forward key, seems it couldn't get any power to go... When I'm entering rear gear, It flyes away.
I also have tested on notebook and it works fine... but on my computer simulation looks very strange.

Do you have any notes why that happent and maybe I can switch something to make a simulation more stable ?

[manny]

lol, that looks like fun.

I also couldn't get the vehicle to work, besides that, it seems to be way to costly in terms of CPU time.
We ended up implementing a simple ray-cast car as we're using this on mobile devices.

[Julio Jerez]

really that vehicle is costly? it is mean to be very inexpensive in tun oc CPU calculations.

Of couse a s implistic Raycast will be simpler, however it is near imposuble to make prediction of a tire model using Ray cast,
this is why I do not even try to make a Raycast car.

Hi Julio,
Do you have any notes why that happent and maybe I can switch something to make a simulation more stable ?

almot not one shwo any interest on the vehicles, or any new feature, so it is a while seem last time I worked on it.

Hi Julio,

I'm cheking for updates as for the vehicle simulation. I'm working on MotionBuilder plugin with Newton physics implementation of a car simulation. But I couldn't make it work properly, from last 3-4 month I have found that car simulation has some bugs and doesn't work correctly. So I coundt finish a plugin and test it.
I know that you are very busy, but just to say that I'm interested in car simulation.
P.S. in 2009 I have made a try to implement physics in MotionBuilder - http://neill3d.com/en/newton-physics-in-mobu
But then autodesk made a PhysX inside. Now I see that autodesk do nothing last 3-4 years and I was thinking that it's a good idea to return back to that development and make some interesting physics features for animators.

[Julio Jerez]

I now have a working version and If I may say, I believe this is one of the most most advanced and realistic vehicle simulation of any real time physics engine

There are two demos, one a high performance Lamborghini Aventador super car, and the other a Military transport, later I will add a formula one race car.
The parameters for the engine, gear box, weight and dimensions are taken from the datasheet tables I found on the internet so they are in the ball park realistic.
other parameters I made up.

The cool thing is that all behavior that are characteristics of vehicles, emerge from the simulation. The Vehicle power slide, drift, tail spin, and do all the things car do.
I am very happy with how is turning out.

I still have some tweaks here and there, but for the most part is all functional, check it out.

Heavy vehicle works like a charm. Suspension and good grip to the terrain amazes me the most. I will check out how you made it. Is there going to be a suspension constraint in Newton?
