Real-Time Modeling and Animation of Climbing Plants | Two Minute Papers #146


Dear Fellow Scholars, this is Two Minute Papers
with Károly Zsolnai-Fehér. This paper is about interactively modeling
and editing climbing plants. This is one of my favorite kind of works:
mundane sounding topic, immaculate execution. There are so many cool things about this paper,
I don’t even know where to start. But first, let’s let’s talk about the modeling
part. We can, for instance, plant a seed, and we
can not only have a look at how it grows as time goes by, but we can also influence the
grow variability and shoot growth rates. Branches can be added and removed at will
at any point in time. We can also add attractors, regions that are
set to be more likely for the plant to grow towards. With these techniques, we can easily create
any sort of artistic effect, be it highly artificial looking vines and branches, or
some long forgotten object overgrown with climbing plants. However, a model is just 3d geometry. What truly makes these models come alive is
animation, which is also executed with flying colors. The animations created with this technique
are both biologically and physically plausible. So what do these terms mean exactly? Biologically plausible means that the plants
grow according to the laws of nature, and physically plausible means that if we start
tugging at it, branches start moving, bending and breaking according to the laws of physics. Due to its responsive and interactive nature,
the applications of this technique are typically in the domain of architectural visualization,
digital storytelling, or any sort of real-time application. And of course, the usual suspects, animated
movies and game developers can use this to create more immersive digital environments
with ease. And don’t forget about me, Károly, who would
happily play with this basically all day long. If you are one of our many Fellow Scholars
who are completely addicted to Two Minute Papers, make sure to check out our Patreon
page where you can grab cool perks, like watching these episodes in early access, or deciding
the order of upcoming episodes, and more. Also, your support is extremely helpful, so
much so, that even the price of a cup of coffee per month helps us to create better videos
for you. We write some reports from time to time to
assess the improvements we were able to make with your support. The link is in the video description, or you

support, and I’ll see you next time!

    I had a giggle when I saw this was going to be a video about "real time modelling" of plant growth.

    If you love watching the grass grow, prepare to be amazed!

    Wonder how long it is going to be before someone puts all these awesome fast modelling techniques together to create a super-realistic virtual world?

    Awesome stuff! Looks almost meditative. Why do all of these always focus primarily on Ivy though? There are all sorts of neat climbing plants

    Why not create a extra channel in which you show of the usage of the software? The short 2 – 3 minute videos are really great but if the people would like to more in depth they have to search them self.

    how about making a list of videos where the code is published too.. Im really starting to get annoyed by all these awesome papers but no further practical use of it..
    Starting is a understatement, iv'e been annoyed since 2010, im starting to get angeryyyy

    damn I loved this one! just few days ago I was thinking that how cool something exactly like this would be and then i saw the notification 😀 this is awesome!

    Not so interesting in 2017, even Maya can do this just as well since they added attractors many years ago. There are plugins for even Unity that lets you do this. For real-time animation this is too slow and its better to just use an advanced VS to create some movement.

    I wonder if this can be used to create other vegetables such as moss djungle like tangled trees.

    It could be used when generating djungles in starcitizen
