Field Detail

frameExporter

cs5643.rigidbody.RigidImageSimulation.FrameExporter frameExporter

Reference to current FrameExporter, or null if no frames being dumped.

N_STEPS_PER_FRAME

static int N_STEPS_PER_FRAME

Number of time steps per large step size.

DT

public static double DT

Size of symplectic Euler time step (in seconds). You may want to change this, but watch out for interpenetrations at high linear/angular speeds!

simulate

boolean simulate

Toggle to advance simulation.

drawWireframe

boolean drawWireframe

Draws wireframe if true, and pixel blocks if false.

drawBounds

boolean drawBounds

Draws object bounds (Disk) if true.

largeStep

boolean largeStep

If true, instead of one step per frame, simulator takes N_STEPS_PER_FRAME.
