Field Detail

trainStartOffset

public double trainStartOffset

Subtract a position offset for the train on the track because Scene 1 frame 1 is over a minute into the movie.

x

public double x

The X component of the vector that was the result of the last computation.

y

public double y

The Y component of the vector that was the result of the last computation.

z

public double z

The Z component of the vector that was the result of the last computation.

rot

public double rot

The rotation of the object that was the result of the last computation.

Constructor Detail

TPos

public TPos(double index)

Creates a new instance of TPos

Parameters:

index - The amount to set the trainStartOffset by.

TPos

public TPos()

Creates a new instance of TPos

Method Detail

setStartOffset

public void setStartOffset(double offset)

Set the start offset for this Tpos. This method is required because we switch scenes in the middle of the volcano database computations.

Parameters:

offset - The new trainStartOffset value

TimeToTpos

public double TimeToTpos(double time)

Return the linear position along the track at this time.

Parameters:

time - The time we are interested in.

Returns:

The linear position along the track. This value can be fed to Get() to get the x/y/z position of this Tpos.

Get

public void Get(double tpos)

Calculate the x/y/z vector and rotation of this Tpos at the linear position passed.

Parameters:

tpos - The linear position (Train POSition) that will be converted.
