Doorless lift WIP
« on: May 29, 2008, 07:27:26 pm »

This project is what you can call a "doorless" lift (or elevator). It is one of the models that were built in Europe in the 70's and 80's. It is still at is very beginning, This is perhaps the most ambitious project I've made. The final animation will have first person views, views from the shaft and views from the machine room.

The motor sound I'm using is awesome. It fits perfectly for a small lift. You can hear the original recording by pempi at:
http://freesound.iua.upf.edu/samplesViewSingle.php?id=33873. I've cleaned the audio and prolonged the landing to 3 seconds.

Anyway, here are some pics of the door:



Next thing will be the door frame. Of course I've to make the cars, the whole shaft, the lobbies at each floor and the machine room. Of course there is rigging, and then, texturing. The most complicated thing to do will be the traction cables, that have to deform around the drive pulley.

Are you from anywhere in Europe?

It seems that these elevators don't exist in the US. That's why Americans are overwhelmed by the lack of safety on these elevators.

I like this kind of elevators in particular, since they are decorative from outside, that is, the door doesn't look like a set of planks.

I used to live in Belgium, now I live in Scotland.
As for safety, I rode these elevators many times and I'm still around   ;D

Me too. What irritates me off is that some YouTube users ride those elevators, for example, in countries Angola or Egypt, and then think that they are typical "third world" elevators. Some of them are quite classy.

I even committed the stupidity of riding one with my back against the doors/walls, while going up. I was wearing a nylon jacket, and the walls/doors are intentionally smooth, no I didn't got to injure myself.

Of course most of them are being replaced to meet the modern safety regulations. And for those that think that they are too dangerous, it is because they never saw a paternoster (I never had a ride on one of those, and I would like too).

I've made all doors required. Still to do are the door frames. Here are more pics:



The large door that you see at the left is for the goods lift. There will be a stair around the shaft of the passenger lifts (these elevators will share the same shaft, and that's what you will see). Of course this is not the final disposition, but it is pretty much close.

Well. I'm starting to have my reservations about this project. Yesterday, I've made an experiment by making a sketch of a shaft. However, it seems that the lights outside the shaft were not behaving as I predicted. The light just gone through the ceilings, lighting the  the ceilings above.

Attached is the mess I've done. Of course the doors won't be stacked as a single object. This is just trial and error (being the error quite evident. I've tried several configurations with the lights, without results).

My guess is that the ceilings have to cause 100% dark shadows, but unfortunately that is a light property. I mean, the shadows cannot be 100% black, because there is always the reflected light, but the ceilings must cause total occlusion. The only way to minimize the blackness of the shadows case I choose the shadows to be 100% dark is to use more than one light per floor (which I was going to use, anyway). Is there any other solution?

Also, I had to change the lights from volume to ray trace, or the rendering would appear to be scratched. Anyone noticed this problem with volume lights before?

I've had the same problem. the render looked really weird. what i had to do was to delete the light and add a new one :S

the doors look a lot alike. I would have made like a crack or somthing in the glass of one of the windows.  That would have looked cool

Well. I fixed part of the lighting problem. However, it seems that the lights on the above floors illuminate the scene below. This wasn't noticed before. I really tried deleting and adding the lights again, but the problem persists. Of course the lights now only illuminate the floors below, and not the ones above as well, as before.

Is there any tutorial about lighting? I' guess that I'm making a step bigger than my legs.

i used to have that a few years ago, but i've given up on using shadows altogether, as i tend to do video, and the render times were just suicidal...  :P

Volume shadows have never worked properly, something Steve is aware of.  Fixing them has been kinda low priority because ray traced shadows work fine and produce a much more realistic effect.  Like colclough, I tend to avoid using shadows at all, if I can, due to the long render times.  The only times you really have to use shadows is in strong, single light scenarios, basically outside on a sunny day or space scenes, etc.  That is for animations of course.  For single model renders shadows, especially soft shadows, can make all the difference.

I think that only happens if your floors are 'infinitely thin' (single yellow/blue face) instead of being a 'cube' (yellow/blue-blue/yellow)

Well, I decided to suppress the freight elevator. It wouldn't make muck sense to have one in an apartment building.

So, in interior scenes, you do not use shadows? Well, that raises a problem: How do you prevent lights from illuminating the other floors?

No, the floors are perfect cubes with 10 units of thickness. I can't find any reason.

I love the lift! It looks so...so real! Not sure about the lighting but the lift is fantastic
