Class GeometryStripArray

  • Direct Known Subclasses:
    LineStripArray, TriangleFanArray, TriangleStripArray

    public abstract class GeometryStripArray
    extends GeometryArray
    The GeometryStripArray object is an abstract class that is extended for a set of GeometryArray strip primitives. These include LINE_STRIP, TRIANGLE_STRIP, and TRIANGLE_FAN. In addition to specifying the array of vertex elements, which is inherited from GeometryArray, the GeometryStripArray class specifies the number of strips and an array of per-strip vertex counts that specify where the separate strips appear in the vertex array.

        public GeometryStripArray​(int vertexCount,
                                  int vertexFormat,
                                  int[] stripVertexCounts)
        Constructs an empty GeometryStripArray object with the specified number of vertices, vertex format, and array of per-strip vertex counts.
        Parameters:
        vertexCount - see GeometryArray(int,int) for a description of this parameter.
        vertexFormat - see GeometryArray(int,int) for a description of this parameter.
        stripVertexCounts - array that specifies the count of the number of vertices for each separate strip. The length of this array is the number of separate strips. The sum of the elements in this array defines the total number of valid vertices that are rendered (validVertexCount).
        Throws:
        java.lang.IllegalArgumentException - if validVertexCount > vertexCount ;

    • Method Detail

      • getNumStrips

        public int getNumStrips()
        Get number of strips in the GeometryStripArray.
        Returns:
        numStrips number of strips
      • setStripVertexCounts

        public void setStripVertexCounts​(int[] stripVertexCounts)
        Sets the array of strip vertex counts. The length of this array is the number of separate strips. The elements in this array specify the number of vertices for each separate strip. The sum of the elements in this array defines the total number of valid vertices that are rendered (validVertexCount).
        Parameters:
        stripVertexCounts - array that specifies the count of the number of vertices for each separate strip.
        Throws:
        java.lang.IllegalArgumentException - if any of the following are true:
          initialVertexIndex + validVertexCount > vertexCount,
          initialCoordIndex + validVertexCount > vertexCount,
          initialColorIndex + validVertexCount > vertexCount,
          initialNormalIndex + validVertexCount > vertexCount,
          initialTexCoordIndex + validVertexCount > vertexCount

        java.lang.ArrayIndexOutOfBoundsException - if the geometry data format is BY_REFERENCE and any the following are true for non-null array references:
          CoordRef.length < num_words * (initialCoordIndex + validVertexCount)
          ColorRef.length < num_words * (initialColorIndex + validVertexCount)
          NormalRef.length < num_words * (initialNormalIndex + validVertexCount)
          TexCoordRef.length < num_words * (initialTexCoordIndex + validVertexCount)
        where num_words depends on which variant of setArrayRef is used.

      • getStripVertexCounts

        public void getStripVertexCounts​(int[] stripVertexCounts)
        Get a list of vertexCounts for each strip. The list is copied into the specified array. The array must be large enough to hold all of the ints.
        Parameters:
        stripVertexCounts - an array that will receive vertexCounts
      • setValidVertexCount

        public void setValidVertexCount​(int validVertexCount)
        This method is not supported for geometry strip arrays. The sum of the elements in the strip vertex counts array defines the valid vertex count.
        Overrides:
        setValidVertexCount in class GeometryArray
        Parameters:
        validVertexCount - the new valid vertex count.
        Throws:
        java.lang.UnsupportedOperationException - this method is not supported
