java.lang.Object

org.distorted.library.mesh.MeshBase

org.distorted.library.mesh.MeshPolygon

public class MeshPolygon
extends MeshBase

Create a polygon of any shape and varying elevations from the edges towards the center.

Specify a list of vertices. Any two adjacent vertices + the center (0,0,0) form a triangle. The polygon is going to be split into such triangles, and each triange is split into adjustable number of 'bands' form the outer edge towards the center. Edges of each band can can at any elevation.

MeshPolygon

public MeshPolygon(float[] verticesXY,
           float[] bands,
           int exIndex,
           int exVertices)

Create a polygon of any shape and varying elevations from the edges towards the center. Optionally make it more dense at the vertices.

Parameters:

verticesXY - 2N floats - packed description of polygon vertices. N pairs (x,y). Vertices HAVE TO be specified in a COUNTERCLOCKWISE order (starting from any).

bands - 2K floats; K pairs of two floats each describing a single band. From (1.0,Z[0]) (outer edge, its Z elevation) to (0.0,Z[K]) (the center, its elevation). The polygon is split into such concentric bands. Must be band[2*i] > band[2*(i+1)] !

exIndex - This and the next parameter describe how to make the mesh denser at the polyVertices. If e.g. exIndex=3 and exVertices=2, then 3 triangles of the outermost band (and 2 triangles of the next band, and 1 triange of the third band) get denser - the 3 triangles become 3+2 = 5.

exVertices - See above.

MeshPolygon

public MeshPolygon(float[] verticesXY,
           float[] bands)

Create a polygon of any shape and varying elevations from the edges towards the center. Equivalent of the previous with exIndex=0 or exVertices=0.

MeshPolygon

public MeshPolygon(MeshPolygon mesh,
           boolean deep)

Copy constructor.

Method Detail

copy

public MeshPolygon copy(boolean deep)

Copy the Mesh.

Specified by:

copy in class MeshBase

Parameters:

deep - If to be a deep or shallow copy of mVertAttribs1, i.e. the array holding vertices, normals and inflates (the rest, in particular the mVertAttribs2 containing texture coordinates and effect associations, is always deep copied)
