#DMM vs KeyFactory?
3 messages in this thread
Is anybody using DMM willing to discuss some of the abilities of each
package? I use Key Factory a bit and though it works great for most simple
situations, I have been disappointed when I get to trying something complex.
I looked at the new file uploaded to the IPAS lib. of DMM dropping "complex"
objects down ramps like the KF demo and was not impressed by the motion at all.
But I was convinced KF could do the same. It did, with a more realistic result,
and the file is there if you wish to look at it.
One thing I noticed is that DMM does it's rotation properly for use with
motion blur. Key Factory use some strange calculation type for it's rotation so
that objects spin almost 360 degrees (on some strange axis) between most
frames. No good for motion blur!
If anyone has used both packages, I would love to hear from you.

One main feature in the DMM vs. Keyfactory debate would be that DMM does not
limit you to the number of groups of objects and in Keyfactory you are limited
to only 4. Keyfactory has several more features though which DMM does not like
the preset for exploding a group of objects and their online help. DMM is very
fast and efficient at doing gravity/motion but Keyfactory seems to have more
features. I have just read that Positron has just shipped V1.1 of DMM with some
new features included. Since I haven't seen it, I can't comment on what the new
features are.

I agree with you. I downloaded the DMM demo and took the same file and applied
Keyfactory to it. I agree that I found that the motions to be more realistic
in Keyfactory. Unfortunately we do not know all the facts (ie: what the
parameters for their software we set at), so our tests may not be fair. I have
not used DMM, but I wish I could, just to make a fair comparison for myself.
The only problem that I ran into with keyfactory with large scenes is the speed
issue. From my limited experience, most collision detection programs when you
deal with hundreds (even thousands) of objects can be slow and tedious. Even
collision programs on SGIs.
I think for a fair test, we need to find out what the settings DMM was and
apply this to Keyfactory, just to see what the results are to best determine
the better or more feasible software.
