Houdini Tutorial: Bending Time With Attributes

[@patrickl9930]

This is also a great way to remove jittering from things like particle sims. You can smooth the Trail output to reduce jitter :)

[@oleit3]

Using the trail output as a way to timeshift by attribute is an amazing idea!! 🤯

Hi, really nice effect. Never heard of the camera coordinate space before. Thanks for this tutorial.

[@olexp9017]

It is called Normalised Device Coordinates, not a camera space. Camera space is quite a bit different thing. 😂

Always great tips and tricks and ideas.

Thank you Entagma

Thanks Chris, really cool!

[@vfxskull6208]

Genius!!

I'm new to Houdini. And wonder what an attribute W is, at 2:40. On the help page it says spline weight. But what does that mean?

[@mukundkm7129]

w vec3 Angular speed of the particle. This can be thought of as a vector giving the rotation axis with its magnitude being the spin rate. Spin rate is in radians per second

@@mukundkm7129 Thank you.

[@wewantmoreparty]

great idea

[@gabrielbeniciobh]

Super cool! :O

An interesting and awesome technique! Sadly it's limited by the original geometry's indices/layout. In real rolling shutter a point could be captured multiple times on a single frame, which I don't think can occur here

[@davidramis-us]

do you think there might be as solution in animating something in 60 frames then re-rendering in 30 fps?

[@martinmenso6671]

Tried with a more complex mesh from Megascans but it becomes a mess. Is this only for simple geometry? Thx

[@sebastianbaalbaki1704]

you could maybe remesh it before timestretch and then pointdeform the hires to remove some ugly deformations

[@septuleptum]

This is insane

[@mukundkm7129]

😋😍

[@yonlaycabrera4431]

It looks awesome and I am very grateful for having such a knowledge for free. However, there are plenty of ways of resolving that same effect with some little Kinefx effort. Why not just making a procedural rig of those cubes? By the way, I haven't tried yet but I think of with a more complex mesh it will not look so nice, just guessing.

Is this channel being run by someone else?

No
