Can someone explain the relationship between screen resolution and the way the the camera control and match perspective works. Also the numbers on page 21 in the new features manual of 3DS 4 does not seem to be correct. Has anyone got those numbers to work.

Wayne, >> Also the numbers on page 21 in the new features manual of 3DS 4 does not seem to be correct. Has anyone got those numbers to work. It seems you're right; those numbers don't give me a result that makes any sense either. Maybe a typo? I'm not quite sure what you mean by your screen resolution question; can you go into a little more detail? John

Yes, there does seem to be a mistake in the "answers" to the perspective matching tutorial. Here is why: Camera and target absolute points can be entered, or dolly distances can be entered, but not both. Entering one will override the other. The definition of Dolly is to "pull back" or "push forward" the camera. Obviously this changes it's position, and consequently the numbers for absolute position will change as well. I think, if you type in all the numbers EXCEPT the one for dolly, you will get the image that they want you to wind up with.

Hi! So we've tried both setting the dolly number and setting the camera/target point numbers – without an appreciably "right" view appearing. What are the right numbers? There is no picture to try and match up to, so its hard to figure out. Thanks!

When I tried plugging in the numbers (except for dolly), I got the house sitting next to the other houses, although it wasn't exactly lined up. <<What are the right numbers? >> Good question. Problem is, there is no definitive answer. With perspective matching it really just boils down to what looks right to you. -Brian
