Constructor Detail

LineStripArray

public LineStripArray()

Constructs a LineStripArray with default values.

Method Detail

isVisible

protected boolean isVisible()

Check to see if this geometry is making the geometry visible or not. Returns true if the defined number of coordinates and strips are both non-zero.

Overrides:

isVisible in class BufferGeometry

Returns:

true when the geometry is visible

render

public void render(javax.media.opengl.GL gl)

Issue ogl commands needed for this renderable object.

Parameters:

gl - The gl context to draw with

compareTo

public int compareTo(java.lang.Object o)
              throws java.lang.ClassCastException

Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

Parameters:

o - The objec to be compared

Returns:

-1, 0 or 1 depending on order

Throws:

java.lang.ClassCastException - The specified object's type prevents it from being compared to this Object

equals

public boolean equals(java.lang.Object o)

Compare this object for equality to the given object.

Specified by:

equals in interface Renderable

Overrides:

equals in class java.lang.Object

Parameters:

o - The object to be compared

Returns:

True if these represent the same values

setStripCount

public void setStripCount(int[] counts,
                          int num)
                   throws InvalidWriteTimingException

Set the number of valid strips to use. A check is performed to make sure that the number of vertices high enough to support the total of all the strip counts so make sure to call setVertex() with the required array length before calling this method. Each strip must be a minumum length of three.

Parameters:

counts - The array of counts

num - The number of valid items to read from the array

Throws:

java.lang.IllegalArgumentException - Invalid total strip count or individual strip count < 2

InvalidWriteTimingException - An attempt was made to write outside of the NodeUpdateListener bounds changed callback method

getValidStripCount

public int getValidStripCount()

Get the number of valid strips that are defined for this geometry.

Returns:

a positive number

getStripCount

public void getStripCount(int[] values)

Get the sizes of the valid strips. The passed array must be big enough to contain all the strips.

Parameters:

values - An array to copy the strip values into

compareTo

public int compareTo(LineStripArray ta)

Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

Parameters:

ta - The argument instance to be compared

Returns:

-1, 0 or 1 depending on order

equals

public boolean equals(LineStripArray ta)

Compares this object with the specified object to check for equivalence.

Parameters:

ta - The geometry instance to be compared

Returns:

true if the objects represent identical values
