It's possible to generate a proper height map, but a GLSL bug stops it from working. I have a plugin that fixes it, which as it happens is now releasable, but I've hit a really busy patch and not had time to put it online somewhere. I'll try to get it done later, or over the weekend at least. It'll let you use vertex sampling in GLSL, which means you can take a grid and change the height of the points using an image, which is what you're after. I'll put an example in showing how to do it (the plugin use isn't exactly straightforward anyway). It won't give you wireframe though - I'm not sure how to do that as I've not tried it. I guess it's fakeable in glsl, or perhaps the kinemeGL tools allow it (I've a feeling that they do actually). (You can find that on kineme.net)
