public class TriangleFanArray

extends GeometryStripArray

The TriangleFanArray object draws an array of vertices as a set of connected triangle fans. An array of per-strip vertex counts specifies where the separate strips (fans) appear in the 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, the previous vertex and the first vertex. This can be thought of as a collection of convex polygons.

Constructor Detail

TriangleFanArray

public TriangleFanArray(int vertexCount,
                        int vertexFormat,
                        int[] stripVertexCounts)

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

Parameters:

vertexCount - the number of vertex elements in this array

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, TEXTURE_COORDINATE_3 or TEXTURE_COORDINATE_4, to signal the inclusion of per-vertex texture coordinates 2D, 3D or 4D.

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

Throws:

java.lang.IllegalArgumentException - if vertexCount is less than 3 or any element in the stripVertexCounts array is less than 3

TriangleFanArray

public TriangleFanArray(int vertexCount,
                        int vertexFormat,
                        int texCoordSetCount,
                        int[] texCoordSetMap,
                        int[] stripVertexCounts)

Constructs an empty TriangleFanArray object with the specified number of vertices, vertex format, number of texture coordinate sets, texture coordinate mapping array, and array of per-strip vertex counts.

Parameters:

vertexCount - the number of vertex elements in this array

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, TEXTURE_COORDINATE_3 or TEXTURE_COORDINATE_4, to signal the inclusion of per-vertex texture coordinates 2D, 3D or 4D.

texCoordSetCount - the number of texture coordinate sets in this GeometryArray object. If vertexFormat does not include one of TEXTURE_COORDINATE_2, TEXTURE_COORDINATE_3 or TEXTURE_COORDINATE_4, the texCoordSetCount parameter is not used.

texCoordSetMap - an array that maps texture coordinate sets to texture units. The array is indexed by texture unit number for each texture unit in the associated Appearance object. The values in the array specify the texture coordinate set within this GeometryArray object that maps to the corresponding texture unit. All elements within the array must be less than texCoordSetCount. A negative value specifies that no texture coordinate set maps to the texture unit corresponding to the index. If there are more texture units in any associated Appearance object than elements in the mapping array, the extra elements are assumed to be -1. The same texture coordinate set may be used for more than one texture unit. Each texture unit in every associated Appearance must have a valid source of texture coordinates: either a non-negative texture coordinate set must be specified in the mapping array or texture coordinate generation must be enabled. Texture coordinate generation will take precedence for those texture units for which a texture coordinate set is specified and texture coordinate generation is enabled. If vertexFormat does not include one of TEXTURE_COORDINATE_2, TEXTURE_COORDINATE_3 or TEXTURE_COORDINATE_4, the texCoordSetMap array is not used.

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

Throws:

java.lang.IllegalArgumentException - if vertexCount is less than 3 or any element in the stripVertexCounts array is less than 3
