  Questions about slope pattern (Message 1 to 2 of 2)

Message: <3cc304d5@news.povray.org>
Is slope {<0,-1,0>,0,1} equivalent to slope{<0,-1,0>}?
similarly is slope {<0,-1,0>,0,1 altitude <0,1,0>,0,1}
equivalent to slope {<0,-1,0>,0,1 altitude <0,1,0>}?
If so, is that true in the general case or just in some cases?

If slope is used in a normal, where is the bump_size specified?

I don't know about the other questions, but the bump_size or depth would be placed
immediately after the closing curly brace of
the slope pattern.

However, in my testing of that feature I saw no difference in the apparent depth. 
Perhaps it is expected that we use a
normal_map and each individual normal of the normal_map would have its own bump depth.
 (Or perhaps my test cases aren't good
enough!)
