I have 3 layers with 3 objects and 3 cameras.  Layer 1: cube + camera1  Layer 2: uv sphere + camera2  Layer 3: torus + camera3  camera1 is active from 1 to 79 frame.  camera2 is active from 80 to 159 frame.  camera3 is active from 160 to 240 frame.  How can I render only   cube in frames 1-79 ;  only uv sphere in frames 80-159 ;   only torus in frames 160-240  ????
I have multiple cameras in a scene. What I want to do is to change which one is active. This way I can view the scene from different angles. How would I do this?
I have been trying to achieve a true mesh displacement on meshes for quite some time, without ever getting it to work.  If I understand it correctly, this experimental feature would allow me to easily displace the vertices of a mesh - or to create new mesh vertexes where needed - to get a displaced mesh in the result, based off an image, but without using a bump map (simpler, faster?).   This all sounds very exciting in theory, but I am having a really hard time finding examples or tutorials that are both recent and whose links function. So I think there is the need for a question here which will call upon detailed and recent answers to bridge that gap.  I'll start with a simple ico sphere:    Then, , I will change the Feature Set to the Experimental one:    I then add a pink granite image to the mesh:    Mark Seams, Unwrap, add image in the UV Editor:      and finally, in the Object Data panel, change the Displacement method from Bump to True as explained :    no result yet:    if I click "Use Subdivision" this is what I get (so I won't click it right now):    Looking into the Node Editor, nothing seems to have changed with the Displacement of the mesh:    so I tried to replicate the node setup seen in  of  (Linear isn't an option, Clip, Single and Repeat are):    ... but the result is a white ICO Sphere, similar to Image 1.  So, can the "Experimental Feature Set" be used to create actual displacement, and modify a mesh?  This is what I'm trying to obtain - but with the image of the texture actually displaying on the mesh (image from ):    .blend file: Using subcaption package but subfigures end up stacked rather than side by side A feature of C++ is the ability to create unnamed (anonymous) namespaces, like so:  namespace {     int cannotAccessOutsideThisFile() { ... } } // namespace   You would think that such a feature would be useless -- since you can't specify the name of the namespace, it's impossible to access anything within it from outside. But these unnamed namespaces are accessible within the file they're created in, as if you had an implicit using-clause to them.  My question is, why or when would this be preferable to using static functions? Or are they essentially two ways of doing the exact same thing? I am looking to prove the following statement false:  Let $k$ be a positive integer, then $k\mid n$ if and only if $k\mid n^2$.  So I am trying to find a $k$ where this does not hold but after aimlessly trying numbers I was curious if there is a methodical way to find $k$. Stance on repost question instead of editing to invalidate answers? I would like to remove page numbering on a specific page. However, the header and footer should remain intact. If I try:  \thispagestyle{empty}   The header and footer disappear. What is the recommended way of removing just the page number? Prove that there are no positive integers $x$ and $y$ such that $x^3 + y^3 = 10^3$. Prove that there are no positive integers $x$ and $y$ such that $x^3 + y^3 = 10^3$.   This is a homework question, and I understand that its part of Fermat's Last Theorem, but when I looked that up to try to figure out the homework, I realized that it is way further than what we've learned in class so far. We have to prove this, but the only way I can think to do it is by exhaustion, which would be extremely lengthy. Any little shove in the right direction would be appreciated. Thanks! How can I change the field names (not the alias) in ArcGIS 10.2?

I just bought a SATA SSD, and wish to install Windows 7 directly on it, but when Windows asks me where do I want to install it, it doesn't recognize any drives.

How it decides how to fix the packages or if they need fixing and the method of fixing? And why sometimes it fails? Can we search posts by number of comments?

I guess I should have used the table environment.

Thanks When the article the is used before theorem names When writing math papers, one sometimes has to refer to some famous theorems, for instance, the Pythagorean theorem.   Shall I write "by Pythagorean theorem", or "by the Pythagorean theorem". When shall I use the article "the"? Showing $\gcd(2^m-1,2^n+1)=1$ A student of mine has been self-studying some elementary number theory. She came by my office today and asked if I had any hints on how to prove the statement      If $m$ is odd then $\gcd(2^m-1,2^n+1)=1$.    It's been a while since I took number theory and I'm not sure what to do. She said she is learning about congruences, primitive roots, and power residues.  She has not taken any group theory.
