Manipulating Photorealistic Renderings | Two Minute Papers #9

dear fellow Scholars this is 2minute papers with K here photorealistic rendering is a really exciting field in computer Graphics it works the following way we use a piece of modeling software to create the geometry of objects then we assign material models to them after that we would like to know how these objects would look like in real life to achieve this we use computer programs that simulate the behavior of light so this is how the scene would look like with photo realistic rery if it is possible to create digital objects that look like if they were real then artists have an extremely powerful tool they can create wonderful images and animations with it is not a surprise that we see photorealistic rendered cities next to real actors in many featurelength movies nowadays Game of Thrones is also a great example of this I've linked to jaw-dropping examples in the description box below take a look the automotive industry also has lots of ads where people don't even know that they are not looking at reality but a computer simulation but in the movie industry the Pixar people were reluctant to use photorealistic rendering for the longest time and it is because it constrained their artistic Freedom one classical example is when the artist says that I want those Shadows to be brighter then the engineer says okay let's put brighter light sources in the scene but then the artist goes no no no don't ruin the rest of the scene just change those Shadows it is not possible if you change something everything else in the surroundings changes this is how physics works but artists did not want any of that but now things are changing with this piece of work you can both use photorealistic rendering and manipulate the results according to your artistic vision for instance the reflection of the car in the mirror here doesn't look really great in order to overcome this we could rotate the mirror to have a better looking reflection but we want it to stay where it is now so we'll just pretend as if we rotated it so the reflection looks different but everything else Remains the Same or we can change the angle of the incoming sunlight but we don't want to put the sun itself to a different place because it would change the entire scene the artist wants only this one effect to change and she's now able to do that which is spectacular removing the Green splot from the wall is now also so not much of a problem and also if I don't like that only half of the reflection of the sphere is visible on the face of the bunny I could move the entire sphere but I don't want to I just want to grab the reflection and move it without changing anything else in the scene great it has a much better cinematic look now this is an amazing piece of work and what's even better these guys didn't only published the paper but they went all the way and founded a startup on top of it way to go the next episode of 2minute papers will be very slightly delayed because I will be holding a 1-hour seminar at an event soon and I'm trying to make it the best I can my apologies for the delay hm this one got a bit longer it's a bit more like 3 minute papers but I really hope that you liked it thanks for watching and if you like this series become a f scholar by hitting that subscribe button I am looking forward to have you in our growing group of Scholars thanks and I'll see you next time
