Examples of javax.media.j3d.LineStripArray

javax.media.j3d.LineStripArray
The LineStripArray object draws an array of vertices as a set of connected line strips. An array of per-strip vertex counts specifies where the separate strips appear in the vertex array. For every strip in the set, each vertex, beginning with the second vertex in the array, defines a line segment to be drawn from the previous vertex to the current vertex.

            if (firstGeometryHasTextureCoordinateIndices) {
              format |= IndexedGeometryArray.TEXTURE_COORDINATE_2;
            }
            
            // Use non indexed line array to avoid referencing the whole vertices
            geometryArray = new LineStripArray(coordinatesIndices.length, format, stripCounts);            
            for (int j = 0; j < coordinatesIndices.length; j++) {
              geometryArray.setCoordinate(j, vertices [coordinatesIndices [j]]);
            }
            if (firstGeometryHasTextureCoordinateIndices) {
              for (int j = 0; j < coordinatesIndices.length; j++) {
