Assets APE - DeepMotion Avatar Physics Engine for Robust Joints and Powerful Motors

WebGL platform support was added to APE as shown in the following demo. Which means APE developers can show case their creations to their prospective users now via a web browser without downloading now:

At DeepMotion we always strive to improve our physics engine to simulate robust and accurate mechanical and robotic mechanisms. A new Motor type "Continuous Force Motor" has just been added besides the existing velocity motor and positional motors modes. Here are a few demos.

The 1st video is to compare the effects of force motor, positional motor and joint limits on a prismatic joint simulated by Avatar Physics engine. The force motor is driven by a continuous force in the DOF allowed by the prismatic joint.

The 2nd video is a demo to use the "continuous force motors" configured on two hinge joints and one ball joint to create a "pin ball" mechanism. The pivot point of the ball joint is right above the line passing through the pivots of the two pins. By applying different "torque motors" to the 3 Euler axis of the ball joint the ball is actuated for a perpetual looping through the pins.

The 3rd video is a demo and validation of force motors on slider joints and hinge joints and how they interact with each other.

APE rolled into DeepMotion Avatar. Please go to our updated website: http://deepmotion.com/avatar

 

This is some seriously impressive work. I've been working on a variety of physics-based VR projects, and so the capabilities shown in this asset are really intriguing! Especially as an enhancement/alternative to Unity's physics solutions, with which I've had many frustrating issues.

Is there a resource/documentation somewhere that explains/exemplifies the implementation of the Avatar physics engine in a game? What's shown in the overview videos looks outstanding but I'm having trouble imagining the kind of work that would go into character controllers and the like - stuff like locomotion, animation playback, etc.

Thanks.

 

Thank you for the nice words. We have DeepMotion Avatar Alpha program open to sign-up in the following. Once approved you will be granted FREE alpha test version of the plug-in as well as example Unity scenes and documents regarding to how to apply it in your project:

Regarding character controllers like locomotion please refer to the Avatar Character Engine thread here:

The Avatar Character Engine is also part of the Avatar package integrated with Avatar Physics Engine discussed in this thread.

When is this coming out??

 

@superjayman It is available now. Feel free to sign up the Alpha at: http://deepmotion.com/avatar

 

Hi, I just noticed it includes softbodies support, will that mean I could assign this as a script to a car wheels tire mesh for simulating tire deflation/pressure?

 

It's mainly for simulating deformable organic creature body/muslce/fat instead of car wheels.

 

Ok

 

Your progress is extremely impressive, but I have money to give you, because I need stable joints for a game in production. We've needed stable joints in Unity since Unity became a thing When can we expect a version of APE we can actually ship products with?

Also, will it be possible to just buy the APE part, because I have no need for the other stuff on your page.

Thanks for working hard on this!

 

@Ultroman: Yes commercial license of APE to actually ship products with is available. Feel free to contact licensing@deepmotion.com to share with the team your project requirements.

Video isn't working?

 

sorry, just fixed the video URL.

 

I have just tested this plugin, the result seems to be determinstic on same device(not confirmed with different devices), this is really big step forward compare to all other physics engine that would return determinstic results, which is a big help for networking game, simulating very complicated physics without bog down server's calculation and bandwidth.

The randomness unchecked however does go deep into the dll, which is not exposed to us, I was wondering if somebody in the dev. team could answer testing different devices would result in same detersmintic outcome. Since it seems to be floating point, so I assume all the results is not fixed calculation... so if some how you guys got this to work on different devices, i would be suprised.

 

Thats kinda cool, but what's wrong with the gravity? I notice in nearly all of your videos everything looks slow and underwaterish, but its clear the digger is driving around like normal. Why is the gravity on the rocks so low? They look like inflatable rocks.

 

Is there a way to test this engine? Will it be ever available? What are alternative solutions for articulation joints based on Featherstone’s algorithm which I can use in unity3d do you know?

 

I need this engine!!!

 

I'd recommend trying pybullet for Featherstone / robot physics as an alternative until APE is released (I think pybullet might only work on windows). I used this demo as a base https://github.com/bulletphysics/bullet3/tree/master/examples/pybullet/unity3d then ported pybullet.c to c# to make it more usable / compatible with the existing demos.

 

APE is launched and therefore our Alpha program is closed. However we are still a startup and due to the cost of support we can only service B2B customers for this initial launch. We hope in the future we will be able to create a license or business model for indie developers to leverage APE as well.

For now if you are a studio or company who are interested in licensing APE for a commercial product or project please contact our enterprise/studio sales team with the following form and include the word "APE" in the message:

There are some really really exciting commercial projects/titles being built with APE now by our customers and we might be able to announce one of them in the near future. So, stay tuned !
