Converting Floats to IntPoints and back

[artpen]

Hi guys,

I went all over the documenation and lots of examples. I am basicaly trying to convert each coordinate from float to Clipper Long and after Execute I need to conver all back to floats.
So what I found is when I convert back it does not give me very acurate numbers. I need to go up to 1000 with my scale

Here is how I do it, is it wrong?

// Convert input Vecto3 List to intPoints. Including float precision
    // http://www.angusj.com/delphi/clipper/documentation/Docs/Overview/FAQ.htm
    private void ConvertToIntPoints()
    {
        foreach (var point in PathPoints)
        {
            float scaledX = point.x * scale; 
            float scaledY = point.z * scale;
            IntPoints.Add(new IntPoint(scaledX, scaledY));
        }
    }

    // Convert paths intPoints back to Vecto3s. Including float precision
    private void ConvertToFloat()
    {
        foreach (var path in offsetPaths)
        {
            for (int i = 0; i < path.Count; i++)
            {
                float scaledX = path[i].X / scale;
                float scaledZ = path[i].Y / scale;
                OffsetPoints.Add(new Vector3(scaledX, 0.0f, scaledZ));
            }    
        }
    }

scale declared as float

The scale is essentially what controls the error that you see. The larger the scale you use, the less error should be observed. I tend to scale by 1E4 or more, and because I wanted accuracy more than anything else, I tend to use doubles rather than floats. You will see the range of error if you review the returned values from Clipper; you're simply shifting the decimal point when scaling down.

Thank you Phil. I just thought I am casting in a wrong way
