Package jahuwaldt.j3d.geom

Class GeometryData

  • All Implemented Interfaces:
    java.lang.Cloneable
    public class GeometryData
extends java.lang.Object
implements java.lang.Cloneable
    Data representation of geometry information that is created through the various generator classes in this package.

    This data representation is used to hold information needed to generate geometry from one of the generator classes in this package. In general, data does not get filled in for items that are not requested.

    The type of data to be produced can be changed with each call. While it is possible to ask for both 2D and 3D texture coordinates, the code will only generate 2D values if asked.

    • Field Detail

      • geometryType

        public int geometryType
        This is the type of geometry that you want to have made

      • geometrySubType

        public int geometrySubType
        A generator specific field that describes the type of output algorithm you would like to use for the geometry. May be ignored.

      • geometryComponents

        public int geometryComponents
        The attributes of the geometry you want created. This is an OR'd list of the above variables. It is not possible to generate anything without the raw geometry being computed.

      • vertexCount

        public int vertexCount
        The number of vertices stored in the coordinates array

      • coordinates

        public float[] coordinates
        Storage for coordinate information. These are stored in flat [x1, y1, z1, x2, y2, z2, ...] configuration

      • normals

        public float[] normals
        Storage for lighting normal information. This should be at least the length of the coordinates array. Data is stored in the same fashion. If normals are requested, the count is the same as vertexCount.

      • indexesCount

        public int indexesCount
        The number of items stored in the indexes array

      • indexes
