After a lifetime of not being able to render curves, I have to say its a true joy being able to render curves straight in Arnold. Below is a paint effects brush called ‘gloppy’ that I converted to curves (Modify>Convert Paint Effects to Curves), with a ramp that defines the curve width (lit with an Ai Sky). More examples here.

The animation below was achieved by keyframing the ‘gap size’ attribute of the paint fx stroke from 1 to 0:

I thought I’d put together some old head modeling experiments that I’ve done over the last couple of years. What a bunch of misfits!

I thought I’d share an old post I managed to retrieve that I wrote about multi-touch technology back  in 2007 (apologies for any broken links). Here is a rather poor video of me using my multi-touch keyboard. Unfortunately, apart from the proliferation of touch tablets and touch phones we are still stuck with the inefficient mouse and keyboard setup. Here’s the post:

“I just wanted to view my opinions (for what they are worth), on multi-touch technology and why it will replace the mouse and keyboard in the near future. 2010 or thereabouts apparently. If you don’t believe me, then throw away your iPhone as it uses technology based on multi-touch.

I have been using multi-touch for the last 8 years now – http://www.fingerworks.com

I would never go back to a mouse and keyboard as they are far too inefficient.

Why should I move a mouse pointer down to the taskbar, click on the volume control which pops up something else which I have to click and drag, when I can just rotate my hand like a volume knob. Rotate left to lower the volume, rotate right to increase it. For examples of some of my daily gestures, click on some of the links on this page – http://www.fingerworks.com/userguides.html

Having one device rather than two means I can use my computer in my living room. I don’t need a desk or something to balance a mouse mat on. I can sit, slouch, stand or lie and still use a computer. Having one device means that I don’t have to switch back and forth like I would do if I was using a mouse and keyboard, which is time consuming.

Unfortunately fingerworks was bought out and now we have the iPhone and the new Macbooks have a few multi-touch gestures. It seems they are slowly trickling the technology out to the masses so that eventually consumers will be crying out for a multi-touch device for their computer.

I just wish Apple or Microsoft or whoever would hurry up and release a multi-touch device as good as or better than what I am currently using. However, it took some time to learn it as I had to learn to touch type using the DVORAK layout.

Of course there will be people that will be reluctant to leave their trusty 20th century mouse and 19th century qwerty typewriter keyboard. However the mouse is hugely inefficient
and apparently a major cause of rsi. The qwerty layout was designed to stop the metal hammers on typewriters from hitting eachother and so is also inefficient.

As artists, we shouldn’t be forced to use the same method of input as accountants or secretaries. But we do. To give you an idea of the possible alternates, here is an example of a very possible, method of input that Apple has patented:

I think this image needs no explanation (except that the render is missing one bucket ;o) ). The model is kindly provided by the extremely talented modeler –  Alex Huguet.

Slightly old news, and a bit of shameless self promotion, but I am pleased that one of my images from the Render Curves Tutorial is in issue 62 of 3D Artist magazine.

I am always on the look out for high quality models with which to test Arnold. If you have anything that you are willing to donate to a good cause, it would be greatly appreciated. You would, of course, be credited.

People often ask me (among other things) “Why is your screen resolution so loooow (1024×768)? How can you work like that!”

Well, here are the reasons:

1. It takes less time to move the mouse pointer across the screen which speeds up my productivety immensely.
2. Using multi-touch means that I don’t need to clutter my screen space with space consuming icons and menus.
3. I can move my monitor 1 meter away from my face (recommended distance) and still read the text on the screen.
4. My colleagues can see and read what is on my screen making communication on projects easier.
5. “With higher resolutions comes smaller text” which puts more strain on your eyes and can also lead to headaches.
6. I like to be different okaaaay?

Going to make an effort to add some Arnold render WIP’s and general info during 2014. Lets see how long this New Years Resolution lasts…
