Also take a look at:

AutoCam Off

for your program and resize image in Paintshop Pro for your sig. (800x600 is a bit on the large size)...

My only advice to use the autocam off command like TDK said, texture the matrix and positon the camera somewhere. For example:

I know for a fact that code works, provided you have a texture named "image.bmp", or you can change the texture image around a bit. That matrix is the exact size as one of the arenas in the game I'm making.

You have to remember that when anything in DB is created, it is placed at 0,0,0 in 3D space - including your matrix.

In the case of matrices, it's the bottom left corner (looking down on it from above) that's at 0,0,0. Reposition your objects, but don't move the matrix unless you really, really have to, as Get Ground Height() doesn't work without extra maths to calculate the offset distance you moved it.

If AutoCam is on, then the camera will automatically point at your objects as they are being created. We don't want this, so use AutoCam Off to prevent it.

So, position your object say in the centre of the matrix with:

Position Object ObjNum, MatrixWidth/2, 10, MatrixHeight/2

(The 10 is used to place it just above the matrix so it isn't half hidden).

Next, position and point the camera at the object with:

Position Camera MatrixWidth/2, 30, MatrixHeight/2-20
Point Camera MatrixWidth/2, 10, MatrixHeight/2

This will put the camera 'south' of the object, slightly above it and looking down at it.

Once you can see the object you can play around with the distance values until you get accustomed to the distances...
