public IndexedGeometryStripArray(int vertexCount, int vertexFormat, int indexCount, int[] stripIndexCounts)
vertexCount
- the number of vertex elements in this arrayvertexFormat
- 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.indexCount
- the number of indices in this object. This
count is the maximum 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.
The sum of the elements in this array defines the total number
of valid indexed vertices that are rendered (validIndexCount).
java.lang.IllegalArgumentException
- if
validIndexCount > indexCount

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.indexCount
- the number of indices in this object. This
count is the maximum 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.
The sum of the elements in this array defines the total number
of valid indexed vertices that are rendered (validIndexCount).
