Field Detail

boundaries

protected java.util.List<ExtrudedPolygon.ExtrudedBoundaryInfo> boundaries

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

capVertexBuffer

protected java.nio.FloatBuffer capVertexBuffer

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

capNormalBuffer

protected java.nio.FloatBuffer capNormalBuffer

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

sideVertexBuffer

protected java.nio.FloatBuffer sideVertexBuffer

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

sideNormalBuffer

protected java.nio.FloatBuffer sideNormalBuffer

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

sideTextureCoordsBuffer

protected java.nio.FloatBuffer sideTextureCoordsBuffer

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

cb

protected GLUTessellatorSupport.CollectIndexListsCallback cb

This shape's tessellation.

capFillIndices

protected java.nio.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.

capFillIndexBuffers

protected java.util.List<java.nio.IntBuffer> capFillIndexBuffers

Slices of capFillIndices, one per boundary.

tessellationError

protected boolean tessellationError

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