3D piramide

[Johan Moeskops]

Hi Dave.

Yes, every 60 seconds the piramide rotates 90 degrees to another piece.

I can do it on the way you said.

Thank you very much.

Building on what Dave said, I would figure out the height and width of my sides and make a new comp that size. Call it “side 1” I would then use the mask tool to mask out the triangular side shape. Make sure you turn on the title safe and zoom in to position the top mask point. Next, move your layer anchor point to the bottom middle of the layer. In the project window, duplicate this comp 3 times. Name them Side 2-4.

Create a new comp. Make it a square with the length of your base being the height and width. Drag your side comps into this comp and make them 3d. Switch to the top view and position the first one along the bottom. Dont drag, manually input the numbers. Next, rotate the orientation – not rotation – of the other side comps 90, 180, and -90 degrees, respectively, and position them along the sides and top. Next, create a new null object and apply a slider effect – this will drive the angle of your sides. Alt-Click the x rotation of your side layers and picwip them all to the slider value. Now you can adjust the angle of all the sides together at once.

You should now have 4 sides along the edges of the square comp. Next, adjust your slider control and all 4 sides should rotate in and out together. Zoom in and make sure they meet at a sharp point with no overlap.

Create your main comp whatever size you need. Drag your Pyramid comp in and hit the 3d layer. Also turn on the collapse transformations button. Animate the y rotation of the pyramid comp layer and there you have it. You can go back and apply whatever images for footage to you side comps as you desire. The great thing about this method is that since you used masks, you dont need to be as picky about the source footage as it will always line up and not overlap.

Sorry about the length of this post, but I thought this would help you out.

I forgot to mention, you need to place your footage under the masked solid layer and change the masked solid layer’s transfer mode to alpha stencil so that any layers below it will be triangular shape and not overlap

If it’s only rotating 90deg every 60 secs, is there any need for more than 2 sides? You’d never see more than 2 sides at any one time.

[Mike Park]

That depends on where the camera placement is in the scene and it also assumes that you are going to have the same image on every side. If you have a different image on each side, even assuming that you only need 2 sides, you will rotate and then snap back. Better to build it truly 3d and be able to do anything you want with it. Plus, it is not much harder to duplicate the other 2 sides.

Hi Mark.

Yes, thats a long post, thank you very much.
But I’am not so good in AE.
I’m learning a lot but 3d it to hard for me.
Is it hard to make something for me.
Or it it a stupid question?

I need a white background in PAL with a pyramid.
I can put text on it later

Otherwise I go try it.

Thanks again.

I’ve built lots of pyramids in AE.

All you need are four equilateral triangles and a square that is the same dimension. Lining them up in 3D space is a bit tricky but all you have to do is put the anchor points on the base of the altitude. Get a 15 year old who is taking geometry to fix you up on the basics.

1. New square layer.
2. Apply mask, remove one point so there are only three points.
3. Move the point to the center of the top and down a bit. (if you want to be precise, build this in Illustrator or PS).
4. Duplicate four times. Remove the mask from one of them, it’s the base.
5. Place a null object so its anchor point is in the center of the base. Everything is parented to the null.

This is my standard sigfile so do not take it personally: “For crying out loud, read the freakin’ manual.”

[Johan Moeskops]

Hi David.

You’re right, I have to think better, and read the manual.
But your post is very clear to me.
Now it will go work.

Thanks a lot.

I found a script that does this. If you’d like it just email me at:paulfecht@hotmail.com

I got an email from a gentleman that was interested in this. Hope the script I sent him worked.
