Class ExtrudedPolygon.ExtrudedBoundaryInfo

java.lang.Object
  gov.nasa.worldwind.render.ExtrudedPolygon.ExtrudedBoundaryInfo

Enclosing class:

ExtrudedPolygon

protected static class ExtrudedPolygon.ExtrudedBoundaryInfo
extends Object

Holds globe-specific information for each contour of the polygon. This class is meant only to be used as a way to group per-boundary information in globe-specific ShapeData.

Field Detail

baseVertices

protected Vec4[] baseVertices

The vertices defining the boundary's base. These are always on the terrain.

capEdgeIndices

protected IntBuffer capEdgeIndices

Indices identifying the cap edges in the vertex buffer.

capFillIndices

protected IntBuffer capFillIndices

Indices identifying the cap vertices in the vertex buffer.

capNormalBuffer

protected FloatBuffer capNormalBuffer

A buffer holding the boundary cap's vertex normals. Non-null only when lighting is applied.

capVertexBuffer

protected FloatBuffer capVertexBuffer

A buffer holding the vertices defining the boundary's cap.

capVertices

protected Vec4[] capVertices

The vertices defining the boundary's cap.

faceCount

protected int faceCount

The number of faces in the boundary. (The number of positions - 1.)

locations

protected List<? extends LatLon> locations

The boundary vertices. This is merely a reference to the paren't shape's boundaries.

sideEdgeIndices

protected IntBuffer sideEdgeIndices

The indices identifying the boundary's edge indices in the side-vertex buffer.

sideIndices

protected IntBuffer sideIndices

The indices identifying the boundary's side faces in the side-vertex buffer.

sideNormalBuffer

protected FloatBuffer sideNormalBuffer

A buffer holding per-vertex normals. Non-null only when lighting is applied.

sideTextureCoords

protected FloatBuffer sideTextureCoords

The texture coordinates to use when applying side textures, a coordinate pair for each of 4 corners. These are globe-specific because they account for the varying positions of the base on the terrain. (The cap texture coordinates are not globe-specific.)

sideTextures

protected List<WWTexture> sideTextures

The textures to apply to this boundary, one per face.

sideVertexBuffer

protected FloatBuffer sideVertexBuffer

A buffer holding the side vertices. These are passed to OpenGL.

Constructor Detail

ExtrudedPolygon.ExtrudedBoundaryInfo

public ExtrudedPolygon.ExtrudedBoundaryInfo(List<? extends LatLon> locations)

Constructs a boundary info instance for a specified boundary.

Parameters:

locations - the boundary locations. Only this reference is kept; the boundaries are not copied.
