I see it fine in Thunderbird.

considering you already use vb as a test environment you
might try the following route to avoid reproducing everything
in SDL

1. Use POV-Ray to generate a grey scale heigth image
    (not rendering a height_field, just using texture
    to define terrain elevation). For testing purposes,
    you can skip this step and use handpainted data or
    terrain generated, e.g., from World machine.

2. Create a Bitmap object in your VB App. When determining
    the height of the ground over a position, use Bitmap.GetPixel
    to get the heigth information (rounding to the nearest pixel
    value may ok, otherwise, evaluate the four surrounding pixels
    and calculate the weighted average).

3. At the end of your algorithm, write an include file containing
    a union of spheres for the generated objects.

4. Render a POV-Ray scene containing a height_field based on
    the image and your exported spheres.
