public OF3DFlow(java.lang.String fileName)

Method Detail

setStaticVolume

public void setStaticVolume(Volume vs)

Sets a secondary static volume for which the flow has been computed. This volume is rendered if the flow is zero.

set

public void set(java.lang.Object value,
                int x,
                int y,
                int z)

Description copied from class: Volume

Set the voxel at x,y,z to value.

Overrides:

set in class Volume

Following copied from class: volume.Volume

Parameters:

value - a value suitable for this volume.

x, - y, z the position in the volume.

get

public java.lang.Object get(int x,
                            int y,
                            int z)

Overrides:

get in class Volume

Following copied from class: volume.Volume

Parameters:

x, - y, z the position in the volume you want the value of.

Returns:

the value of the volume at x,y,z.

calcpsiTranslation

public float[] calcpsiTranslation(float vx,
                                  float vy,
