Explanation of parameters? #33

Open ghost opened 7 years ago

ghost commented 7 years ago

I love V-HACD. it really is a life saver!

Is there any explanation of how I should realistically be setting the parameters? For example, I am trying to figure out which combination of parameters would results in the most faithful decomposition vs, which combination would result in a very crude approximation. I can't seem to figure it out by trial and error. Your help is greatly appreciated. Thank you.

Here is a blog post by the author of VHACD http://kmamou.blogspot.ca/2014/12/v-hacd-20-parameters-description.html Hope it will help you.

Maybe put a link into the readme file like this? I had the same issue

PR #62 is adding the parameters into the Readme.md, and would close this issue

Two years later, finally it has happened!

Hi all, I would like to join the discussion about the description of the parameters. The lib is really useful, thanks a lot for that! When I try to decompose objects, it is always trial and error to get good results. Is it possible that you can explain the parameters in more detail? I have the following questions:

What does “Concavity” mean?
What do the parameters Alpha and Beta do? How does these parameters effect the resulting decomposition?
What does “Plane down-sampling” mean? How does this parameter effect the resulting decomposition?
What does “Convex hull down-sampling” mean? How does this parameter effect the resulting decomposition?
Which parameters affect the performance, e.g. when I increase that parameter, the decomposition takes much longer (because it might be O(n²))

Thanks a lot for your answers!
