Designing Holographic Interfaces

In regards to ~28 minutes, the "average" of a noise texture is .5, if you use a math node to subtract .5 from the node path before the multiply it will instead be centered around the starting point.

Hi Ian! apologies if this has been asked/answered but been having trouble finding a solution. Do you know of a way to bake animations created in geo nodes? I've used realize instances to apply the geo node but as such lose the animation

HOW can I export this with transparents background? I want to put holograms on my other video.

you can also make point cloud effect with this. thank you for tutorial! this is really exciting!

Wow, thank you for the response! I had a feeling I was going to have to use an object mask, I was using a video file that has a cool effect along the edge. I think if I use the two in conjunction I should be able to get the exact look I need. Thanks for the information definitely going to use it!

yeah, that's not enough transparency bounces. you theoretically can put in any number up to infinity. But that's caused by alot of overlapping geo. One way is to bool, or rather mask the area that should vanish. Sadly in Blender you cant write Shader Output to UVs or onto Vertex Group, but if you control the shader using a Shape like a sphere, you can use a Proximity Modifier to write it into a vertex group and then Mask it by that VertexGroup. In the shader, the Object Info Node you most likely already derive the mask from takes in an Object as Input, select it. and anime the object rather than the mask inside the shader. voila.

i am SO exited that you are mentioning resolve! Im looking forward to get more into using it.. I have the paid version, but i pretty much just use it to stich the pngs together..

Hi Ian! So I was playing around with the transparency shader to make on object (pretty complex geometry) disappear using a mask as the factor. It worked great for some parts but I ended with these black artifacts that weren't transparent. I tried bumping up everything in light paths but it never full went away. Any idea how to fix it?

Also... this is totally unrelated, but i found your portrait at the National Gallery in London: https://twitter.com/DavidLisser/status/1512094627658088448

Thanks for tricking me into a geo-nodes tutorial. It’s been on my ‘to learn’ list for ages. I’ve watched a couple of tutorials and found similarly to yourself that often nodes are added without telling me why I needed it. Would love more of this, and also excited about a fusion tutorial too

"The Offset socket is basically just a vector math Add node". Absolutely! :)

OH! The Offset socket is basically just a vector math Add node? That makes sense! Thanks for that :D

cool to see you do geometry nodes stuff! and looking forward to some videos on your resolve / fusion workflow

It is just great that you do Geonodes now! the first tutorial that I could follow to the end :D 2 suggestions: 1-Your green keys are very feathery sometimes times now that you do Fusion there are way more complicated methods watch Simon Ubsdell channel keying tutorials he is a pro. 2- I think you can use a prop for the floor, right now it does not feel that the talent's foot is connected to the floor. if you use some sort of SciFi carpet you will solve the problem and worst case scenario if it doesn't work you can Roto it later.

Glad to hear you're working in resolve! Escape the clutches of Adobe!

Yeah! I'm happy to see you diving into geometrynodes! Your excitement about it is a pleasure to me. I see you used the hold method (#frame) but since B3.1 there is a node called "Scene Time". BTW, you don't necessary have to use a vector math node at 26' and 33' of the video, the Offset socket input is here to do the job.
