AMotor Euler Mode Joint axis 1

Actuated Character — Sat, 09 Jul 2011 18:24:48 -0000

According to ODE's documentation : http://opende.sourceforge.net/wiki/index.php/Manual_\(All)#Angular_Motor

"There is an important restriction when using euler angles: the theta 1 angle must not be allowed to get outside the range - pi /2 ... pi /2. If this happens then the AMotor joint will become unstable (there is a singularity at +/- pi /2). Thus you must set the appropriate stops on axis number 1."

This limitation is not enforced by EZPhysics Editor or Lib.

Network Angular Velocity

Actuated Character — Sat, 09 Jul 2011 17:45:30 -0000

Angular Velocity is a 3 float vector.

In the network it holds 4 floats.

Network Torque

Actuated Character — Sat, 09 Jul 2011 17:41:14 -0000

Torque is a 3 float vector.

In the network it holds 4 floats.

Warning about Hinge2 2 bodys restriction

Actuated Character — Wed, 29 Jun 2011 16:43:39 -0000

ODE requires that any Hinge2 has 2 bodies (instead of allowing for 1 environment).

This is not upheld by our code. A warning should be enforced.

Mesh collision with grounded objects

Actuated Character — Wed, 29 Jun 2011 16:39:48 -0000

When colliding proxies and mesh with a rounded object that has mesh collision activated it does not collide

Normalization Assert

Actuated Character — Thu, 13 Jan 2011 11:27:50 -0000

If running simulation in Normal WorldStep, the application may assert an null vector normalization within the calculation.
This happens due to large invalid values in the simulation. ODE has exploded.

The problem is that the assert is sent to the user and not handled by the exceptions mechanism.

ODE simulation speed

Actuated Character — Thu, 13 Jan 2011 11:24:32 -0000

The simulation speed diminishes every time you run one i.e. Pressing start and then stop.

This is a very noticable decrease in speed.

Major Memory Leak

Actuated Character — Thu, 13 Jan 2011 11:22:36 -0000

Every time the ODE simulation runs there is a large allocation of memory, it is then not completly realeased.

Running the simulation for long period continually increses the memory used.

Grounded status not saved

Actuated Character — Thu, 13 Jan 2011 11:15:49 -0000

In some cases the Grounded status is not saved (or loaded) in the sim file, even if it works in the application.

New Helper invalid old save files

Actuated Character — Wed, 15 Dec 2010 11:23:05 -0000

The inclusion of the new helper mesh for the representation of the center of mass, has created a problem when loading all previously saved sim files without the Editor.
