# density of rigid body

Hello,

Is there a way to create a rigid body using given density rather than
given mass? The only thing related (somehow) to density, that I have
found is hkpInertiaTensorComputer::setAndScaleToDensity() method, but I
have no idea how to use it :( Please anyone could help with this?

And another question, is there a point in setting mass/density
attribute to rigid body that has hkpPlaneShape shape? Does greater
mass/density of plane change behavior of objects during collisions?

# setAngularVelocity problems

Hi, we're trying to set the angular velocity of a rotating object, the problem is that it's not responding very well. We're setting the angular damping to 0 after which we try to set the velocity with setAngularVelocity(). The problem is that there's some kind of threshold before it starts to spin at all, and when that is reached it starts to spin to fast. It's as if there's inertia affecting the angular velocity and we're trying to apply impulses each frame.

# how good is havok

1.is the graphics good.

2.can you make a full game (destructible and eveything)game out of try havok e.g i am a big fan of war of the worlds can i make it into a game.

3.how long does it take to make a full game let's say 15 mission's.

4.can you make people's(a.i.citizens etc..)reaction's real.

5.can you destroy anything e.gmy war of the worlds game i want to make zap a building in the building enough and it breaks in half and falls to the ground and breaks.

6.are the people (when killed)like euphoria.

# Ball-Socket Chain Constraint with hkpHingeLimitsData

We've created a mostly neatly behaving fish by using a combination of a ball socket chain with hkpHingeLimitsData. We map the RBs of the fish with our bones in our render system, this works perfectly for most cases, there's a problem here though:

Hi everyone :-)

First of all, thanks for a possibility to play with Havok just for
free, I think this is a great thing for all of computer graphics
enthusiasts :-)

I have been working on kind of academic research, trying to compare
different Physics Engines. I am to write similiar application -
simulating massive number of objects' collisions - under Havok, PhysX
and ODE. Being honest, PhysX (release done by AGEIA, not nVidia) comes
with great "Training Programs" tutorials and with ODE also I had no big

# Probleme with Scene Transform Filter

Hello,

I've got a little problem with the Scene Transform Filter when trying to export a mesh, it always told me :
Transform Scene Filter
Warning [0xabba45e4]: Inversion failed. Check the Matrix is not singular

I just wonder if it's a knowed problem because even with a box and the IDENTITY preset it won't work

Best regards

# Compatibility with GNU GCC compiler?

Are the Havok libraries compatible with the GNU GCC compiler?

# Visualizing Physics Objects in Game Editor

Hi,

i'm aware that it's possible to use the visualdebugger to visualize physics object and custom data i have in the scene

but it it possible to get a set of polygons ,lines that i can visualize in my own Game Editor? if so how?

Thanks
