Hi,
Just a quick point.
>The TriangleStripArray essentially supports only two rows of points.
This isn't the case. Each strip consists of two 'rows' of points, but you can have
multiple strips. I have used this to
represent a 2D grid of coordinates. No idea if this is what you where thinking but the
following code generates a
TriangleStripArray from a grid of Point3fs (represented as a 2D array).
Cheers,
Brad
public TriangleStripArray createGeometry(Point3d[][] coords) throws Exception {
int numRows = coords.length;
int numCols = coords[0].length;
System.out.println("NumRows=" + numRows + " NumCols=" + numCols);
int[] stripCounts = new int[numRows - 1];
for(int i=0; i < stripCounts.length; i++) {
stripCounts[i] = numCols*2;
}
TriangleStripArray ta = new TriangleStripArray( (numRows - 1) * (numCols * 2),
TriangleStripArray.COORDINATES, stripCounts);
int coordCount = 0;
//for each strip
for(int i=0; i < stripCounts.length; i++) {
//for each col
for(int j=0; j < numCols; j++) {
ta.setCoordinate(coordCount, coords[i][j]);
coordCount++;
ta.setCoordinate(coordCount, coords[i+1][j]);
coordCount++;
}
}
return ta;
}
