Matrices and rotation!

Sorry, it took me so long to respond. If you wanna do it with glsl, you can use TDRotateOnAxis func to create a mat3, given an axis and an angle, and then just say position *= rotation, where the position is a vec3 and the rotation is mat3. If you don't wanna do it with GLSL, you probably can use something like Point Transform TOP, which is basically applying a bunch of different matrix translations to the input. But I think this is exactly a scenario that I've covered in this tutorial, so maybe I'm not exactly getting what you wanna do :)

Hi Noones! How can I rotate all instanced geometry at once, around the center point? thanks

appreciate the reply, i have managed to maps the video to a height map, i think i then need to apply velocity field to this some how, i'll keep experimenting!

Hey! I'm not exactly sure how to do that! But I think you can achieve something similar if you look at this tutorial https://youtu.be/rkunS8T69qI And then experiment with different ways to generate a velocity field from an image. Maybe some combination of curl and slope can get you somewhere close, Cheers 🙌

PS i think the video needss to be turned into a height map then from there particles ? something like this

Hey! I've been trying for a while to get an effect where pixels in a video are turned into particles and they travel with the video using some sort of flow field and fluid simulation. Would you be able to possibly create a tutorial as i think everyone would love to see as well? if not could you point me in the right direction! thanks :) here is an example https://www.instagram.com/p/CVnrBqDvr3M/
