Hi everyone

 

This thread is being set up for the Random 42 Live Project - Medical Visualisation (level 5 3D Animation). If you are enrolled in this class, please feel free to post your work here for feedback. I will share the thread with the staff of Random 42, so those of you who have questions about the project can post them here. 

 

I have placed some example models courtesy of Callum Welsh (virus, receptors, clathrin coat) on Rex

 

T:\2017-18\Level5\Random42

 

Be warned they are gigantic! remember that the virus and the receptor are modelled at the atomic level; each bulge / sphere shape is an atom. I suspect the clathrin coat is of a similar scale.

 

Start posting!

Hi everyone,

 

Just to say I will be keeping an eye on this thread and be showing it around the company on Friday afternoons, so try and get stuff posted by lunchtime on Friday if you want some critic from us. Otherwise I will be checking in from time to time as well!

 

Martin should have a copy of notes if you want to check over them again, but I also have some links that were used in the presentation:

To start my assignment, I figured that I would model a blood vessel and try using an Ncloth simulation in Maya to block out basic shapes of the tissue. This was what my initial attempts turned out:

It's far from perfect, but it's a start! I'm probably going to try exporting another cloth sim and sculpting it in zbrush to give it further texture. I hope to use it as a base for the procedurally generated cells.

That looks cool! Was the blood vessel a modelled object that you dropped onto cloth to get it to billow up like that?

Here's some examples of the procedural shaders I made for a virus receptor (the bit that sticks out of the virus and connects with the liver cell)

The left hand side one is the most complex, but it looks really unpleasant which is the effect I wanted :) I'm going to try to make something more pleasant for the poor innocent liver cells who don't know what's coming :)

@Moid

Thanks!

I tried that at first, but I found that it was more effective to instead use wind to blow the cloth upward and around the stationary blood vessels model.

Thanks, that's a great workflow idea - it looks really good.

Looks really good so far! - got a nice organic look to it. Be interesting to see how you approach the cells.

Hey, here is a design sketch for my Hep B cell

I know they deviate abit from what the cell originally look like but i quite like the idea of having tenticle/hair like things for the large surface proteins. inspired alot by Alexy Kashpersky work and things like plants and sea urchins. would like to know which one you find the most interesting . thanks  :)

Yer Alexy takes a lot of liberties with his images, there aren't too accurate per say, but they so look fantastic with all the additional detail that he adds. 

 

I would recommend doing a colour pass of them as well (with the receptor and lipids too) as that can really determine what details pop compared to the rest and in my opinion can add as much definition as the surface details. 

 

Personally I'm liking 2 at the moment, I think 1 looks a bit too much like it's latched to a surface so may look strange travelling, and 2 has more visual interest than 3. Those tendrils add some nice silhouette and with some cloth like movement on them could add so much life in the animation, even if the base virus animation is quite simple. It could really sell the cell being in some kind of viscous fluid or something if you have it move like seaweed.

 

Reminds me off this: http://i.vimeocdn.co...21_1280x720.jpg

 

Also i think the shorter receptor feel better, as it want to feel like a solid lock to the surface of the cell. That's not to say you can't have the other receptor on the surface in the BG. There will be a lot of different types of receptors on a cell surface

I think you've managed to make a very unpleasant virus look cute :) That's a useful skill I think! I like the top left, bottom left and the bottom middle ones the most if that helps.

I like this too, it makes me think of a jellyfish crossed with some sort of fungi

@Maria For the first image, my main critic would be that the the liver cells look almost diseased - blueish colours I would associate with de-oxygenated or dead cells, where the warm orange of the virus looks healthy. I think the palette of colours are interesting, but they are going to really work against you when trying to portray the virus as "evil" and destroying the "good" cells. The colours here can do a lot for storytelling. For us, we usually portray "mutated" things as green, as that is a colour a lot of people associate with radiation.

 

For the second image i feel it would be good to experiment with light on them too. Do you want to light them quite diffuse in a warm environment, or go for more of a back lit and abstract lighting. You could also perhaps have light inside the virus emitting out of the pores. I like to emit light out of a nucleus as it's often thought of as the powerhouse, and i like the idea of lots of energy radiating from it. Lighting can also do wonders for surfaces with visible repetitive patterns, whether i the texture or the model. The virus could look very interesting with maybe those evil reds or a slightly unnatural blue light emitting from it, which releases into the cell once it's taken in. Another option for the bottom left image might be to have illumination on the end of the spikes, to get a greater contrast in interest points

The warm vs cool theme though could be interesting though. The hot virus infects the cool / relax cells, heating them up and causing them to eventually melt or break apart from the heat.

 

That can also have the virus as a light emitter, which adds to it's unnatural and destructive feel, vs the cells which do not. The colours would still have to be moved around a bit to make this work. Something can feel "cool" without being a strong blue/green, and the virus can feel "hot" without being that natural Mediterranean skin tone
