Maya for 3D Printing - Rapid Prototyping
In this course we're going to look at something a little different, creating technically accurate 3D printed parts.

The Park

I'm starting modeling the park down the street from my house. I just started on a set of bleachers, but there is a whole lot more to be done. Including a playground and a couple more benches for sitting, some large boulders and a basketball court. A LOT of stuff!!

I have reference images and sketches with dimensions for correct size of objects. I have about 150-200 high resolution pictures of the park different angles and some closeups for textures (hopefully) when I get to the texturing.

But here are the bleachers for now. Only including a couple of the reference pictures, because you don't need to see 10 pictures of 'em haha. There won't be close ups for the bleachers in the scene so I'm not adding the bolts as of yet, I might anyway just for the sake of having them.

looks good so far

on an off topic note, what ever happened to your transforming usb stick?

Thanks

The USB stick, well that is something I've put on hold for a while. Still trying to figure out just how exactly I'm going to do it. Maybe I'll revisit it soon and see what I can do.

And here is a sandbox with a contraption in the middle that I don't quite understand. All you can do with it is fill the little digging thing with dirt, you can't swivel around or anything in it, so it seems pointless to me, and a bit awkward seeing kids try to use it.

Render, I added a little bit of color to it real quick just to make it stand out a bit and I did away with the physical sun and sky lighting in the render:

Looks good man

Why not use textures and normal maps for the bolts and such?

I didn't even think of doing it that way. I'm going to need to learn some of that stuff, it's about time. I went and added some geometry as the bolts for the merry go round today, it looks pretty cool. I'll look into normal maps. Thanks for the idea!!

Not sure if anyone will see this soon and be able to help, hopefully.

Anyone know how I should tackle this slide? Not quite sure how I'm going to do this yet. I was thinking a helix, but I'm not sure. And the hood, should I just block it out with a poly cube? I don't know why but I'm having a hard time figuring this out

you could use a helix
cut off the top half and extrude the outside a bit. although I dont know how you'd stick the giant pole shape down in the middle

maybe you could start with a cylinder, make it as tall as you need then draw in the helix around it and extrude that out.

although that could be a lot more time consuming than the above and sticking a pole in the middle and then just adjusting the verticies on the pole until it matches the helix so you can delete some faces and merge

the hood itself can be left overs from the helix that you use to make the slide.
so you delete the top half of the helix but leave the end.
i'd show you what i mean better but this computer has no maya

Well I appreciate the help. It's kind of what I was thinking but was kind of hoping there would be a bit of an easier way haha. I'm not too worried about the pole merging with the slide, as long as it fits in there and looks like it could be attached to it. It's not really going to be getting any close up shots, although I would like to make it look as good as I can just in case I want to use this playground for something else at some other time.
As of right now all I have is a pole sticking out of the ground and no slide going around it yet. haha

I'll have to play around with it a bit.

If anyone else has any ideas of how they would do it let me know, I'm open to suggestions.

You could create a cylinder for the middle pole, then from there use a helix as a guideline and add edges in a spiral around, then extrude the edges outwards, then upwards and refine it from there... Would probably be easier to just use a helix and cut off the top half though :p But with the cylinder you would get the smooth transition form pole to slide user added image

EDIT: Chirone said all that way better than I did :p

Thanks acid.

I also was told on cgsociety I could give extruding along a curve a try. I've never really used curves before, so that should be interesting trying to figure them out.
Was screwing around with a helix yesterday and it doesn't quite do what I need it to, although I didn't spend a lot of time tweaking things, which I'm sure I'll need to do.

Well I took a short break from this while my dog was at the vet, turns out she has diabetes, but she's back home and doing well with her insulin injections

Anyway tonight I got to the twisty slide. I can't say it was easy, took me forever!! I used a helix and previously made pole that I put into position and wrapped the helix around. I wasn't worried about it molding to the pole like it is in real life because I'm not going to be doing any close ups of the slide.

you're dog has diabetes? how'd that happen?

good work with the slide

how'd you make the holes in that railing panel thing?
