Class 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.

      • locations

        protected java.util.List<? extends LatLon> locations
        The boundary vertices. This is merely a reference to the paren't shape's boundaries.

      • faceCount

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

      • capVertices

        protected Vec4[] capVertices
        The vertices defining the boundary's cap.

      • baseVertices

        protected Vec4[] baseVertices
        The vertices defining the boundary's base. These are always on the terrain.

      • capFillIndices

        protected java.nio.IntBuffer capFillIndices
        Indices identifying the cap vertices in the vertex buffer.

      • capEdgeIndices

        protected java.nio.IntBuffer capEdgeIndices
        Indices identifying the cap edges in the vertex buffer.

      • capVertexBuffer

        protected java.nio.FloatBuffer capVertexBuffer
        A buffer holding the vertices defining the boundary's cap.

      • capNormalBuffer

        protected java.nio.FloatBuffer capNormalBuffer
        A buffer holding the boundary cap's vertex normals. Non-null only when lighting is applied.

      • sideIndices

        protected java.nio.IntBuffer sideIndices
        The indices identifying the boundary's side faces in the side-vertex buffer.

      • sideEdgeIndices

        protected java.nio.IntBuffer sideEdgeIndices
        The indices identifying the boundary's edge indices in the side-vertex buffer.

      • sideVertexBuffer

        protected java.nio.FloatBuffer sideVertexBuffer
        A buffer holding the side vertices. These are passed to OpenGL.

      • sideNormalBuffer

        protected java.nio.FloatBuffer sideNormalBuffer
        A buffer holding per-vertex normals. Non-null only when lighting is applied.

      • sideTextures

        protected java.util.List<WWTexture> sideTextures
        The textures to apply to this boundary, one per face.

      • 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.)

      • ExtrudedBoundaryInfo

        public ExtrudedBoundaryInfo​(java.util.List<? extends LatLon> locations)
        Constructs a boundary info instance for a specified boundary.
        Parameters:
