Oh oh that was a year ago and i made it with a few different softwares. Im more into making geometry nodes tutorials but if people will want it i might do it and try to keep it in blender as much as possible. Thank you for asking
Pure genius, the most efficient and versatile culling technique I could find. Thank you so much for your clear explanations and the time spent to transmit your knowledge. I learned a lot :)
Great and thank you for sharing, I have made one of my own (Camera Culling) but not so sofisticated, it works but..... your version is amazing and the tuto is great, I learned a lot . 🙂👍
True, true in some cases it will look odd due to reflections but it most cases it will look fine. Also when you are rendering grass most of the times you will have nothing behind the camera(just a plane with instances) so with reflections it should look weird anyway
Help us get started on the path to knowing how to do this math. What are the main foundation math skills you think people need in order to become a person like you who can figure out such things for themselves?
Wow that is an amazing question. Maybe the best i was asked. And if I could do full time RU-vid that is what I would do probably because its so important and the main problem for ppl who Don't understand nodes. If I will have time i would love to do so.
Thismethod of camera culling is very solid. However there must be a more performant way than casting a Ray for every single instance... there are ways to calculate this with math, I have yet to find a way to make it work in GN.
Yes you are correct! I have made a camera culling with math although i like the raycast method for 3 reasons. 1. Its simpler to make. 2. I wanted to explain the blender's camera and with raycast is easier to do so. And 3. Some features i still didnt managed to achieve just with math like the x and y shift etc. And i haven't tried it too hard Also i made a few tests with math camera culling and the results are not as dramatic as i thought. The math was around 1.5 faster which is not bad but i expected more haha. Also if im not wrong you dont need to raycast for everything instance if you plug the selection to the density input of the distribute points node cuz it based on the topology. Thank you very much! I might make another tutorial for math altho the important thing for me was to explain how the camera in blender is working.
Im volunteering at the moment. In general doing 3d for around 5 - 6 years but never really took an actual full time job. Also having some geo nodes node groups on gumroad
