Field Detail

boundaries

protected List<ExtrudedPolygon.ExtrudedBoundaryInfo> boundaries

The boundary locations of the associated shape. Copied from that shape during construction.

capFillIndexBuffers

protected List<IntBuffer> capFillIndexBuffers

Slices of capFillIndices, one per boundary.

capFillIndices

protected IntBuffer capFillIndices

The indices identifying the cap vertices in a shape data's vertex buffer. Determined when this shape is tessellated, which occurs only once unless the shape's boundaries are re-specified.

capNormalBuffer

protected FloatBuffer capNormalBuffer

A buffer holding the cap normals of all the shape's boundaries.

capVertexBuffer

protected FloatBuffer capVertexBuffer

A buffer holding the Cartesian cap vertices of all the shape's boundaries.

cb

protected GLUTessellatorSupport.CollectIndexListsCallback cb

This shape's tessellation.

sideNormalBuffer

protected FloatBuffer sideNormalBuffer

A buffer holding the side normals of all the shape's boundaries.

sideTextureCoordsBuffer

protected FloatBuffer sideTextureCoordsBuffer

A buffer holding the texture coordinates of all the shape's faces. Non-null only when texture is applied.

sideVertexBuffer

protected FloatBuffer sideVertexBuffer

A buffer holding the Cartesian vertices of all the shape's side vertices.

tessellationError

protected boolean tessellationError

Indicates whether a tessellation error occurred. No more attempts to tessellate will be made if set to true.

Constructor Detail

ExtrudedPolygon.ShapeData

public ExtrudedPolygon.ShapeData(DrawContext dc,
                                 ExtrudedPolygon shape)

getOuterBoundaryInfo

protected ExtrudedPolygon.ExtrudedBoundaryInfo getOuterBoundaryInfo()

Returns the outer boundary information for this shape data.

Returns:

this shape data's outer boundary information.

iterator

public Iterator<ExtrudedPolygon.ExtrudedBoundaryInfo> iterator()

Iterates over the boundary information of this shape data.

Specified by:

iterator in interface Iterable<ExtrudedPolygon.ExtrudedBoundaryInfo>

Returns:

an iterator over this shape data's boundary info.
