public class IndexedTriangleStripArray

extends IndexedGeometryStripArray

The IndexedTriangleStripArray object draws an array of vertices as a set of connected triangle strips. An array of per-strip index counts specifies where the separate strips appear in the indexed vertex array. For every strip in the set, each vertex, beginning with the third vertex in the array, defines a triangle to be drawn using the current vertex and the two previous vertices.

Constructor Detail

IndexedTriangleStripArray

public IndexedTriangleStripArray(int vertexCount,
                                 int vertexFormat,
                                 int indexCount,
                                 int[] stripIndexCounts)

Constructs an empty IndexedTriangleStripArray object with the specified number of vertices, vertex format, number of indices, and array of per-strip index counts.

Parameters:

vertexCount - the number of vertex elements in this object

vertexFormat - a mask indicating which components are present in each vertex. This is specified as one or more individual flags that are bitwise "OR"ed together to describe the per-vertex data. The flags include: COORDINATES, to signal the inclusion of vertex positions--always present; NORMALS, to signal the inclusion of per vertex normals; one of COLOR_3, COLOR_4, to signal the inclusion of per vertex colors (without or with color information); and one of TEXTURE_COORDINATE_2 or TEXTURE_COORDINATE_3, to signal the inclusion of per-vertex texture coordinates 2D or 3D.

indexCount - the number of indices in this object. This count is the number of vertices that will be rendered.

stripIndexCounts - array that specifies the count of the number of indices for each separate strip. The length of this array is the number of separate strips.

Throws:

java.lang.IllegalArgumentException - if vertexCount is less than 1, or indexCount is less than 3, or the sum of all stripIndexCounts is not equal to indexCount

Method Detail

cloneNodeComponent

public NodeComponent cloneNodeComponent()

Creates a new IndexedTriangleStripArray object. Called from a Leaf node's duplicateNode method.

Overrides:

cloneNodeComponent in class NodeComponent

Returns:

a duplicate of the IndexedTriangleStripArray object.

See Also:

Node.duplicateNode(javax.media.j3d.Node, boolean), Node.cloneTree(), NodeComponent.setDuplicateOnCloneTree(boolean)

duplicateNodeComponent

public void duplicateNodeComponent(NodeComponent originalNodeComponent)

Copies the information found in originalNodeComponent to the current node. This routine is called as part of the cloneNodeComponent operation.

Overrides:

duplicateNodeComponent in class NodeComponent

Parameters:

originalNodeComponent - the node to duplicate.
