Subject: Same projection on all sides of a cube.


Analog-X64 ( ) posted Sun, 24 October 2010 at 11:30 AM · edited Tue, 30 July 2024 at 1:29 PM

I just want to confirm something.

 

I wanted to apply a picture to a cube so that if I rotate the cube, you would see the same image in each face.

 

  1. I created a top shader with Flat Mapping

  2. I created a Texture Map under the flat mapping and was able to add the image.

No matter what I tried, I can only display the image on only one side of a face at a time.

So does this mean that what I"m trying to do is not possible?

Do I have to manualy create a cube?

For what you are trying to do I think it would be easier to create the cube in the modelling room and then UV map it. Export the UV map and create the texture via an external image editor then load the completed texture to your cube.

But that is just the way I would do it my self. If you have any issues with UV mapping etc I would be happy to help you out by creating it for you.

You can simple create a (1) Vertex cube like Benney said.

So click in the UV editor (2)

Select the Box face in mapping dropdown (3)

Set Full Box in the mapping options (4) and all images that you add to the object will replicate in every face. You dont need to export the UVmap since its a square image.

I followed **GKDantas** instructions and this is the result.** **

Is this the result that you were looking for?

this is what i get with gk's settings (c7pro cube primitive converted to vertex object).  select all polygons prior to applying mapping.

Yes you need to select all the cube to map the image to all sides.

If you still can't get your picture on all six sides, instead of using box, use custom, then under operations select the six figured version and export it as a .bmp and plant your face on all six sides.

We are assuming that you have version 7 or 8.  Jan 

 


Analog-X64 ( ) posted Fri, 29 October 2010 at 5:57 PM

I'm using version 8 Pro.  Ok I'll try again.

 

But here is another question.  Am I applying the mapping in the Vertex Editor? or in the Shader Editor?

Here is a screen shot of How i've set this up.  I'm sure I'm missing a point somewhere.

I have Carrara 7 Pro.  With mine I didn't use projection mapping at all.  Jan


Plutom ( ) posted Fri, 29 October 2010 at 6:41 PM

I used the simple box method that Dantas used.  Jan

Thanks Plutom, that was the missing link.  I was using the wrong method of texturning the cube.

So why am I going through this excercise? I want to build on this idea and make a cool effect of some sort.

Maybe instead of a still image, using a video and projecting the samem video on all sides of the cube.

Or Multiple videos, each video shown on each side of the cube face.

And while this is all happening, maybe have the cube rotate in all axis. :)

I appreciate the guidance from everyone on this thread, and I'm going to build on this in this same thread.


Plutom ( ) posted Sat, 30 October 2010 at 7:34 AM

I'm glad to help.  I've never done video and it would be very interesting seeing what you can do with it on a six sided cube.  Jan


Analog-X64 ( ) posted Sat, 30 October 2010 at 10:26 AM

I'm at work now (yeah I know its saturday), but when I get home I'll try and post the video test i did.

I'm having diffuclty with video looping properly.  I have a 2 second video and trying to have it loop on the face of the cube a bit longer.

I tried setting a Sine Wave in the tweening but didnt get the results I expected.

I'll post photos and hopefully a video clip to illustrate what I'm saying.

yeah, it should work with  movie files on the rotating cube faces.

Ok.. so it took me some time to figure out that I needed to play with the Master Shader in the animation timeline, to get the animation to repeat more than the 1 second that the actual animation lasts.

Attaching a screenshot for those who may also want to follow what I did.

So the next question is, when I tried to add the spin modifier, it spins too fast and I havent been able to figure out how to slow it down.  I tried playing with the "Cycles per second"  setting, but all I manged to do, was make the cube spin faster and even change directions.


Miss Nancy ( ) posted Sun, 07 November 2010 at 11:03 PM

one method is to use number of frames (n) in imported movie loop as number of frames in rotation of cube.  at time 0 in carrara, the cube is 0 z-rot, at frame n it's 90, 180, ... 360 (as desired).  then the rendered movie loops, rather than trying to rotate the object svl. times in carrara.  in poser it's slightly different - render to frame n + 1 to get it to loop.



Analog-X64 ( ) posted Tue, 16 November 2010 at 8:53 PM

Alright here is the final result.  I manged to crash the shader editor while making this.  The Juggler is facing the wrong direction, but I can no longer edit the .car file to fix the texture.

http://www.youtube.com/watch?v=-jvptqmkhSQ

 

As you can see in the video, I have build upon two concepts.  One is to have rotating cubes spinning in all 3 axis not just one, and while that is occuring to have an animation projected on the cube.

I have a bigger project/picture in mind, this is just a small portion of it.

Any comments or suggestions would be appreciated.

PS: I wish rendo would allow embeding of youtube video into a forum post.

I remeber this animation in the old Amiga good times!

Follow me at euQfiz Digital




Analog-X64 ( ) posted Wed, 17 November 2010 at 7:24 AM

Yes, that is the famous Amiga Juggler animation, its amazing to think, the animation was all done with source code, without any of the tools we use today.

Thats the theme I'm going with, the entire video from start to end will be Retro looking and related to the Commodore 64 / Amiga.

Originaly I wanted to keep a secret and it somewhat is, since I dont mention it, out in the open elsewhere.

But I'm going to need to learn a lot and will need more help. :)  I mean this simple looking animation took a bit of time to learn to make.


GKDantas ( ) posted Wed, 17 November 2010 at 9:31 AM

Just ask and we will try to help.

o.k., the secret is out.  mum's the word.  these anims get easier after the first 100 or so. rendo does not want users to embed in these posts (excepting sigfiles), but they allow flv posts in their gallery.  the realisation is dawning on folks that flash embed is security risk, slows down whole page, and flash's days are numbered.

Thanks for the tip, I'll take a look at putting .FLV in Gallery, or I can try what you did with the Animated GIF.

I've got these animation ideas and effects that I know Carrara can do... now its just a matter of doing  Brain to Carrara conversion :)
