did you know that there are unbelievable research papers on How to simulate the life of virtual trees we can write a computer program to simulate how they move by interacting with them with a mouse if we go too hard we can simulate how they break and if we feel like it we can even burn a tree down or simulate not one Burning Tree but even an entire Forest dear fellow Scholars this is to many papers with Dr car now for a more peaceful simulation we can simulate the life of complete ecosystems for a thousand years as well this is a story of human Ingenuity yes all of these were handcrafted techniques no AI of any sort was used to make this and I have good news for you fellow Scholars we even have more papers in this area and I have found some new ones that are beyond amazing for instance the previous works showed what happens above the ground but a great deal of a tree's life also happens underground as this popular tree develops over time so do its roots as well now take a careful look at the shape of the roots and now have a look at this pine tree growing wow the popler went vertical the pine went horizontal now why does this happen well popular trees are rapid growing but relatively shortlived trees and they primarily grow in areas where water is deeper down in the soil and with these roots they can reach them now the pine tree sees the world entirely differently its roots are horizontal thus maximizing water and nutrient absorption near the surface as an additional bonus it gets stabilized in unfriendly environments where the soil is loser very smart now what about the oak is a wise tree and what does a wise tree do of course it diversifies its bets its deep tap rooot system gives it access to deep water sources but it also has widespread horizontal roots for maximum nutrient absorption thus giving it great longevity great choice H I feel a bit like David atoro here however the story does not end here a good tree root simulation has to take into consideration how smart and adaptable these little plants are you see environmental stimulus matters a great deal in their development for instance when growing around the slope of a hill it will need a different kind of root system to survive loving it so is that it is that all this simulator can take into consideration well not quite now hold on to your papers and look at this fellow Scholars holy mother of papers it simulates the effect of all of these parameters and this is not even a complete list for instance it simulates how different kinds of soils exist and show a different growth resistance factor and we can also mix them up so it can simulate heterogenous systems what does that mean well multiple soil types scattered across this virtual world absolutely beautiful and the tree will grow as a tree should grow in reality hopefully and as we change the distribution of soil types so does this wise little tree adapt to its environment it even learns to avoid regions of high growth resistance and it grows around it thus simulating asymmetric growth so good and now I wonder how much computation does such a simulation take I mean we need to simulate these virtual trees for years and years so does it take years and years of computation time in real life look at that not at all fellow Scholars we can simulate some such a system on the scale of months in a matter of seconds simulating 60,000 little roots in less than 3 seconds and sometimes even interactively wow now at this point I have one more question left you know what it is are these simulations for show or is this how reality works well let's see about that when compared to a previous paper that digitizes tree root system systems in real life this is the

real deal now does the simulator live up to these results look at that my goodness Clean Sweep loving it not only the kinds of structures are very similar but I actually have to look real close to find the differences it needn't be perfect and yet it almost is wow and it gets better the root and shoot ratios for real trees are not known and the simulated Oaks properties are very similar to the ones seen in real trees and now imagine that the games and virtual worlds of the future could be with simulations that are this realistic we could play in these world in the future what a time to be alive and once again all this was done through sheer human Ingenuity no AI technique was used in this paper and the paper contains so much more analysis you simply have to take a look a beautiful piece of work of course it is because this is a sigraph paper what is that sigraph is the most sacred place for some of the best computer Graphics papers ever getting a paper accepted there is in my opinion like winning the Olympic gold medal of Graphics research huge congratulations however computer Graphics is a field that is orders of magnitude smaller than AI research for instance look at this goodness this paper was seen by about 200 fellow Scholars and I fear that if we don't talk about works like this here on two minute papers almost no one will here I try to be a good ambassador of computer Graphics research and show everyone how amazing these papers are and can give to the world so much and it breaks my heart that so few people know about them but good news I have more papers like this up the sleeve if you wish to not miss out on them when they come in the future make sure to subscribe and hit the Bell icon experiment tracking model evaluation and production monitoring for your deep learning projects and llm apps this is what weights and biases does and it is the best everyone is using it try it out now at wnb domme slapers or click the link in the description below
