Making a Ray-Traced image expand

Running CS6 on Mac OS. I was wondering if you could do something like a stroke reveal effect like you would for a fake handwriting effect work on an extruded image. Like if I had an extruded Q, could I make it "grow" in a circle if I'm usuing Ray-Traced (which I know is rather limited). I'm open to any suggestions. I'm not getting my hopes up on this one but I'm hoping someone might have a creative idea at least how to cheat and get some kind of similar effect.

The raytracer responds to animation in extruded shape layers, which can include any Merge Paths operations like subtracting stuff from shapes with otehr shapes and animate the cutting object to create a reveal...

Problem with noise/artefacts in AE6 Ray Traced mode.

I'm having a problem with some kind or weird artefacts appearing on parts of an imported Illustrator layer. Here's the import procedure I'm using:
In AE6 I switch to Ray Traced 3D mode, then I make a new comp, add a camera, import my Illustrator file, drag it into the comp. Then I right-click on the Illustrator file in the comp and and select "create shapes from vector layer" then make the layer 3D. I can extrude etc. but for the sake of this post, I didn't do that. I get the artefact regardless.
Here's a cropped portion of my Illustrator file showing the problem:

Here's another screen-cap showing the problem from a different angle:
http://img717.imageshack.us/img717/4757/lines2.jpg
The sample image is in full res and set to AE's "final quality" mode.
I've tried different setting for the render quality (the same image is set to 10), but it seem the higher the quality I set it to, the more obvious the artefacts become!
I've added no lighting or anything else to the scene, jut the camera and the AI file. I've also inspected the Illustrator file inside Illustrator and I cannot see anything at all that can be causing this problem. Is it perhaps an export setting problem in AI?
These lines only appear when I use the "create shapes from vector layer" option.

Thank you very much for your reply.
Could you please explain to me how to import the paths in the manner you describe? I'm not overly familiar with Illustrator, other than loading and saving artwork.
If it's any help, here is the Illustrator file as supplied to me: homepage.ntlworld.com/mike1962/cnet.ai
Thanks,
Mike.

Ray Tracing question

Hi all,
In Java2D the tracing algorithm can handle effectively primitive shapes, like cubes, spheres etc, mapping the shapes from 3D to 2D. So we can, for example, rotate the whole "scene" and have a 3D illusion of the world. But what about images? The ray tracing algorithm uses the 3D coordinates system, so how can we handle the 2D representation of an image? I know that in Java3D there are special Loaders that load a description of an image and tranform it appropriately in the 3D world. Is there any way to have a 3D representation of an image in Java2D?
Thanks

helmik,
LabVIEW does not do symbolic math. Once you have the equations solved on paper or reduced to a set which can be solved numerically, tehn you can program it in LV.
When I look at your math in the first post, I see that in (3) you describe an equation in x and a. However, this is not a quadratic equation but a fourth order polynomial with terms like a^2*x^2 and 2*a^2*x*y_0. So this is not so easily solved.
Is not the tangent to the sphere at right angles to the radius at that point? The angle of the radius can be calculated from x_0 and y_0 and the center of the sphere. Then add 90 degrees. One arctangent and no complicated equations.

Effects Don't work with Ray-Traced 3D?

Hello,
I'm working on a 3D logo for a company, and I'm trying to snaz what I have done with some effects, but the effects don't work. For example, I tried adding the CC Light Wipe Effect, but it will only show up when I switch back to the classic 3D renderer. Google searches aren't exaclty effective when I my serach quiere has "Effects" and After Effects" in it, so I'm forced to come here looking for the answer.
Are effects supported in this new renderer? If so, how do I get them to work?
Thanks

Pre-composing and then switching off Ray-traced rendering in the main comp gives you the ability to apply effects to the pre-comp. This may or may not work for your situation.
Another option is to pre-render your Ray-traced work and then apply effects to the footage. There's almost always something you can do if you think about it for a while.
Still another option is to put a 2D adjustment layer above your 3D Ray-traced layer and apply the effect there.

How do i create a gallery page that you can click on an image, expand it and move left or right to see more images?

Why does my font/text change when I switch from Classic 3D to Ray traced 3D in After Effects?

My font/text changes when I switch from Classic 3D to Ray traced 3D. Why is it doing this? Also, I cant get the font/txt to look the same after I switch from Classic to Ray traced. How can I get it to look the same?

I am pretty new to After Effects so I hope it's not my inexperience that's causing the problem. (It probably is)
I just updated to the most current version of AE.
I am on a mac pro late 2013 12GB 6 core. Running OSX 10.9.4
Okay so after looking at it a little closer, I think the color is what mostly changes. The first screenshot is the what the text look like with Classic 3D and the second screenshot is what it looks like after I change it to Ray traced 3D. Also under the "Mode" section..the pull down that says "Normal" disappears. I'm wondering why the font color is changing?

Earser on traced image

Hi,
I got an Illustrator Trial to see how well it works for inking scanned drawings. I watched a few online lessons and already stumbled into a problem that I can't seem to solve, so any help would be appreciated.
I'm using a non-english version so I hope my translations of the actions are not to confusing.
I imported the scanned image to illustrator and then used object->image tracer and converted it to a vector graphic with area fill and no stroke. So far so good.
I now want to erase little mistakes in the drawing, that look like this
if I use the eraser, this happens:
so the path is weirdly bend around the stroke of the eraser, which obviously isn't what I wanted to achieve. In all the videos I watched about the eraser, it worked fine and if I just create an area with the blob brush and erase a part of that, that works fine as well. What's so different with the traced image?
Thanks in advance

Hi,
yes that kinda works but I think that would be too much work for that many details. Also it somehow leaves behind another path:
So.. maybe somethings wrong with the way i convert the traced image?

Using tracing image, then replacing with background image

I am very new to Dreamweaver, and am trying to put together a very simple site.
I am using a tracing image for the layout table mode – and am tracing it exactly. However, when I out put it to test in my browser,
nothing lines up how it shows in my work environment.
Am i missing something "very" obvious? Thanks.

1) Don't ever use table layout mode. It's a terrible way to build web pages.
2) No matter how hard you try, you can't make stuff stick to a big background image. It's like trying to nail Jell-O to a wall.
Have a look at the following tutorials. These will get on the right track.

Flash image expands out of container only on Safari browser

I have this test page where flash image expands out of the container only on Safari browser, everything else works fine (I.E,Chrome,Mozilla,Opera) http://itmjobs.ro/lidl/eu.html . I have tried to insert flash image into a table, the same thing happent. I have tried to change iframe size to very small 10/10 just for test, I don't know how but only Safari it brings full size whatever I do.
Can anyone help to fix this problem ? Thank you
alfateam

You may not like my answer but don't use Flash. Most web designers gave up on it long ago because the world's most popular web devices (iPhone, iPad, iTouch, Android, etc..) don't support Flash and never will.
If you want to reach a wider audience with fewer problems, use an image map and jQuery maphighlight script.

Gt645m not supported for ray tracing?

Hello guys recently i bought a laptop with 645m GPU its MSI c61 was having 2nd thought of buying the other laptop which has 650m because of $250 difference and when searched for the both GPU specs its almos the same so i just bought gt645m instead and use the $250 on SSD but my gawd now i am in deep trouble.. because gt 645m is not supported by after effects and in this site it says this video card is OEM..
http://www.studio1productions.com/Articles/AfterEffects.htm
when i go to preferences on AE cs6 the GPU is greyed and wont let me choose it so its CPU in default. sadly i cant return it now cause i already bought the ssd and have no budget at all
Is there anyway that i can use this card? for AE and Ppro? geezuz cries..

ok i did that..
and so i got this error
After Effects error: Ray-traced 3d: Initial shader compile failed. (5070 :: 0)
and when i removed my card from the list the error is gone . and GPU is not supported again .. of course

When support After Effects Ray-traced 3D the GPU of the new iMac with retina display (GPU: AMD Radeon R9 M295X 4GB)?

I would like to know whether After Effects CC Ray-traced 3D support the GPU of the new iMac with retina display.

It never will. This is nVidia-exclusive technology and the whole things is deprecated, anyway. You better learn to use Cineware, buy a 3D program like Pro Animator or Element 3D or learn a proper 3D program.

Complicated easy question - ray tracing

Hello,
i am working currently on one project - i have an optical system (some prisms, some lenses etc) and i want to make a VI to calculate propagation of a light ray - something like ray tracing.
I know that labview is not the perfect platform to deal with this issue, however i still would like to try.
My problem is as following: i want to calculate the propagation of a ray through a lens. I have the ray with some coordinate (y=const) and a plano convex lens - the front of a lens is a piece of a sphere. To calculate the propagation (using snell law) I have to find an angle between the ray and the line which is tangent to this lens-sphere in the point where my light beam hits the lens.
My procedure (on the piece of paper):
1.i know the coordinates of a center of a sphere (let's take (0,0)) and its radius r (x^2+y^2=r^2). I know the value of y=y_0 for which the ray enters the lens.
then i can calculate the x_0: x_0^2+y_0^2=r^2. Now i know the point where light enters the lens (x_0,y_0)
2.then just the usual procedure of finding equation for a line tangent to sphere (y=a*x+b):
i put y_0 and x_0 to this equation:
y_0=a*x_0+b
and i can remove one unknown value (for example b): y=a*(x-y_0)+x_0
3.then i put such equation into the equation for sphere (x^2+y^2=r^2) and this is the quadratic equation which has only one unknown value x and one free parameter: a.
4.beacause i want to have tangent line, so it should have only one common point with sphere - so the quadratic equation should have determinant equal to zero (only one solution for x). This gives me an equation for a. I should find the value of a which satisfy this equation and then i know this tangent line and have the solution! uf....
Unfortunately i still didn't find a solution to implement this in labview (and i'm motivated beacuse most of the work for this project is already done). I was trying with the formula parsing and so on, but i didn't succeeded.
I will be really grateful for any hints or help!
Solved!

Pre-comp 3D Ray-Traced text quality

I've made some text in AE. It looks smooth and great until I pre-comp. Then it gets some aliasing around the edges and is nowhere near as smooth.
Text looks aliased in the pre-comps. If I click the 3D icon on my master comp, it becomes smooth in master comp. Unfortunately, I can't leave 3D checked on because I want to apply effects to the 3D text - hence, the pre-comps. Changing the ray-trace quality and anti-alias filter type does not appear to change anything for me.
Any suggestions?

Thanks,

I'm not exactly sure what your comp looks like but here are some guidelines. If you want to use Ray Traced rendering then you cannot apply certain effects, blend modes and other things to the 3D layer. If you pre-compose and collapse transformations you should be able to then apply effects to the pre-comp and still see the 3D and move around the object with the camera. If you turn on the 3D switch for the pre-comp the effects will then go away and the edges will show aliasing.
The Collapse Transformations switch looks like a * and is just right of the shy icon.
If that doesn't solve your problem then we need to see a screenshot and maybe a flow chart of your project.

Ray-tracing on GPU disabled on MacBook Pro with double graphic card

Hi to all,
i've just installed the demo version of after effects on my new macbook pro 15".
It has these 2 graphic cards:
Intel Iris Pro Graphics
NVIDIA GeForce GT 750M
2GB memory GDDR5
But when i open After effects CC i get this error:
Ray-tracing on GPU requires a dgraphic card NVIDIA approved and CUDA 5.0 or above. At the moment ray-tracing will use just the CPU.
I've seen on NVIDIA that mine is a CUDA GPU: https://developer.nvidia.com/cuda-gpus.
Why am i getting this error?
Thanks

> Maybe updating your graphics driver could help. Your current version is 310.xxx while the latest version is 331.xxx but if your card is not on adobe's supported list, i guess AE won't let you use it.
No.
This is not about the graphics driver. It is, as I said, about the CUDA driver.
Also, you are incorrect about After Effects not letting you use a card that is not on our whitelist; that is why there is the option "Enable untested and unsupported GPU..." (which is "Abilita GPU nontestata e non supportata..." in the original poster's Italian version).
