Class ExtrudedPolygon.ExtrudedBoundaryInfo

java.lang.Object

gov.nasa.worldwind.render.ExtrudedPolygon.ExtrudedBoundaryInfo

Enclosing class:

ExtrudedPolygon

protected static class ExtrudedPolygon.ExtrudedBoundaryInfo
extends java.lang.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 java.nio.IntBuffer capEdgeIndices

Indices identifying the cap edges in the vertex buffer.

capFillIndices

protected java.nio.IntBuffer capFillIndices

Indices identifying the cap vertices in the vertex buffer.

capNormalBuffer

protected java.nio.FloatBuffer capNormalBuffer

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

capVertexBuffer

protected java.nio.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 java.util.List<? extends LatLon> locations

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

sideEdgeIndices

protected java.nio.IntBuffer sideEdgeIndices

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

sideIndices

protected java.nio.IntBuffer sideIndices

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

sideNormalBuffer

protected java.nio.FloatBuffer sideNormalBuffer

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

sideTextureCoords

protected java.nio.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 java.util.List<WWTexture> sideTextures

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

sideVertexBuffer

protected java.nio.FloatBuffer sideVertexBuffer

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

Constructor Detail

ExtrudedBoundaryInfo

public ExtrudedBoundaryInfo(java.util.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.
