for example i'm chopping a oak tree but if i angle myself there is walls blocking it so you can't actually see it despite the client saying it is visible.Is there a way I can tell if the oak tree is actually not visible to the eye etc.

Don't think so.

Don't think so.

what she said

It's possible I guess, but not build-in the API and not beginner's stuff either.

I suppose it would be possible

 

Use the camera yaw angle to determine what positions are located between the tree and the viewport (not as difficult as it may sound).

Find all of the objects in these positions

Intersect the model areas of every one of these objects with the model area of the tree.

The remaining area (if any) is what should be visible on the screen.

Thats was what I was thinking... but it seems such overkill xD

How you determine if the model is infront or behind the object?

You could compare the camera yaw angle to the angle between the supposedly blocking object and the tree. If they differ more than ~90 degrees or so, it shouldn't be in front. The yaw angle might need to be translated first, though.

Ya, there is a lot of shit going on to get this idea working though.

Would like to see somebody try ^^
