Surf's up wave project

Hi,

About a month ago I started an 'internal' project in Houdini. The goal was/is to recreate a fully animatable and artistically tunable breaking wave system, similar to the one used for the awesome waves in the animation film Surf's Up. I started posted progress on this project on one forum and then another, so I ended up setting up a blog where I post updates on the project. I hope it's not a problem to link to that blog in stead of posting updates directly in the forum as it takes too much time duplicating posts in multiple forums...

Anyway, would love to hear thoughts and critiques on this project: http://dvfx.dutcheffectsfactory.com

Cheers,
Erik

Sunset dreams

I've posten another update on my blog, with a new 'backlit sunset' look.

Cheers,

great work Erik - this is coming along nicely - added your blog to my faves page so I'll be sure to check in on its progress.

some small details to consider. Would be nice to start seeing the particles upon where the wave collapses over - this will help you figure out how much you will hide and what can be done.
Also - bear in mind some slight spray coming off the highest portion of the wave would help.

the shader is nice and fairly varied in colour and texture but I would make it more of a blurry reflection through the mesh.

great work tho

Thanks! It's a lot of fun to work on. I'm currently setting (or better resetting) up the lipspray particle system. After that more particles will follow for whitewater and mist, etc... The shader is fully customizable... you can set its parameters for 5 different zones on the wave, so you could basically make it do anything you like and tune it further using a nice set of render passes in a comp (again with masks for the different zones).

Cheers,
Erik

I would really like to get my grubby mittens on houdini - it looks incredibly powerful. Theres a chap in our offices whose very good with it and uses python too with it and he fires out some really clever stuff with it.

great work - looking forward to seeing more with it. Do you plan on adding anything in the water? A boat for example being toppled maybe?

I've Houdini to death I've got it for about 2 months or so now and it seriously rocks! And the peeps at SideFX are really great to work with as well. There's some python in my wave system as well and more coming up, although I mostly use it for the setup of the wave system. I'm thinking of doing some smart python stuff to make it very easy to set up slices of particle systems so I can generate them in parallel as they currently only use a single thread (and thus CPU/Core). I currently do this manually which is a pain.
But first I'll be posting a first render with my completely new setup for lip spray, which is looking promising

Cheers,
Erik

I've just posted another update on my blog: http://blog.dutcheffectsfactory.com with a first render of the new lip spray particle system.

nice little effect on the lip mate - I'd vary it a bit more so theres some coming off lower portions of the wave.
also small detail and not very noticeable in motion but you can see where the uv texturing repeats as the wave rolls

good update tho - looking forward to seeing this with a more surfer camera (less static and robotic and more 'handheld' )

Thanks! There is more detail in the lower parts but its a bit hard to see in these lighting conditions I know about the foam texture, I slapped that one together quickly some time ago to get a good view on the effect of my 'pref' setup (the way the strip of wave combines with the overall ocean surface with integrated UV's). I really need to fix that last seam to make the texture completely seamless, as its really distracting currently.

Cheers,
Erik

Multi-pass

I've updated my blog with a new update on multi-pass and some fixes...

Shades of white water

I've just posted a monster update to my blog (http://blog.dutcheffectsfactory.com) on a new white water shader I wrote from scratch that combines tons of control while keeping data sizes relatively low.

Cheers,
Erik

Yesterday, I posted an update on my blog with a first animation of the 'white water explosion': http://blog.dutcheffectsfactory.com

nice update mate - just a few things I'm sure your aware of (but its nice to have a checklist I think lol) ..

frm50 - just to the right of the centre of screen you can see the texture in the water mesh repeat - any way you can fix this?

frm90 - reflection in the water especially as it collapses feels too much like clear glass - can you get softer refraction through the water maybe?

particles - great work overall altho I think there should be a bit of a 'softer' edge to the lip of the wave - maybe a few more particles that precede that lip could be worth a try?

I think some sort of self shadowing or ambient occlusion would really help it - when the wave topples over and crashes on itself thats where it is certainly noticeable that the AO is missing. Maybe the renderer is doing that but it could stand to be enhanced if so especially a darker area in the tube.

these are just details and I'm aware they could be tough to fix but just thought I'd post up my thoughts - overall its a superb wave effect mate and really captures the same feel they got on surfs up

Thanks a ton for the detailed feedback! I'm actually working on fixing some of these

Cheers,
Erik

Tools 'r Us: Setup and Animation

Hi,

Just posted a new update on my blog: http://blog.dutcheffectsfactory.com. I'm starting to get quite far along on making the wave system a full fledged tool. This post is a first in a series on what the tool looks like and how its used to generate breaking waves.

Cheers,
Erik
