- 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.
-
TriangleFanArray(int, int, int[])
- Constructs an empty TriangleFanArray object with the specified
number of vertices, vertex format, number of strips, and
array of vertex counts per strip.
TriangleFanArray
public TriangleFanArray(int vertexCount,
int vertexFormat,
int stripVertexCounts[])
- Constructs an empty TriangleFanArray object with the specified
number of vertices, vertex format, number of strips, and
array of vertex counts per strip.
- 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 or TEXTURE_COORDINATE_3, to signal the
inclusion of per-vertex texture coordinates 2D or 3D.
- 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: IllegalArgumentException
- if vertexCount is less than
PRIM_SIZE OR sum of all stripVertexCounts is NOT equal to vertexCount.
(PRIM_SIZE is 1 for point, 2 for line, 3 for triangle, 4 for quad etc)
