Mathematica apprentice

My gravatar was made with the following Mathematica code:

Graphics3D[{
  GrayLevel[.3], Specularity[White, 15],
  Lighting -> {{"Directional", 
     RGBColor[.3, .3, .4], {{5, 5, 10}, {5, 5, 0}}},
    {"Point", Black, {12, 3, 15}},  
    {"Point", White, {12, 3, 4}}},
  KnotData[{"TorusKnot", {2, 5}}, "ImageData"]}, 
 ViewVector -> {{0, 0, 5}, {0, 0, 0}}, Boxed -> False, 
 Background -> None, Axes -> False, ImageSize -> 1000]

comment Mesh and ParametricPlot
I don't think this is documented - I can't find it myself. There are a lot of undocumented things in Mathematica - it wouldn't be so much fun if everything was documented... :)

comment Mesh and ParametricPlot
Try Show[Graphics[{}, Method -> {"TransparentPolygonMesh" -> True} ], ParametricPlot[a {Cos[t], Sin[t]}, {a, 1, 2}, {t, 0, 2 Pi}, Mesh -> None, PlotStyle -> Opacity[0.2]]] - see this Q&A for more...

comment Cut out circle out of circle
In the November 2011 video referenced in the linked question in Kuba's comment above, Chris Carlson refers to the forthcoming Mathematica version 9 release as containing "polygon boolean operations, differences, unions, intersections, and so forth ...". So there's a possibility that in version 10 there may be a debugged and reliable set of geometry Boolean functions... :)

@Vaggelis_Z It was ssch's idea, really, so you could vote up one of these by way of thanks :)

comment Modified ListPlot, how to speed it up
re @kuba's comment on brevity, remember Pascal's "I have made this longer than usual because I have not had time to make it shorter." You can focus on the main problem, and worry about the coloring and formatting later...

comment Is Mathematica comparable to C++ for creating standalone applications?
@DanielLichtblau so you wouldn't recommend C++ over Mathematica then? :)

comment Slow image processing using ReplaceAll
You could try ImageApply[2 #[[3]] - #[[2]] - #[[1]] & , p] but it's slightly different...

comment Is Mathematica comparable to C++ for creating standalone applications?
Hi gekannt! It is difficult to ask this kind of thing here, because it involves opinions and discussion, and these are not the preferred type of question (see here). I would suggest that you try a small proof of concept using CDF technology - if it looks promising, spend a bit more time on it. The demonstrations site gives a good idea of what visuals you can expect.

comment Is Mathematica an Implementation of the Wolfram Language?
I think the "Wolfram System" is the term now used to describe what we currently think of as Mathematica. The term "Wolfram Language" is the language in which you write code in the "Wolfram System", or what we currently call (loosely) the Mathematica language, rather than the whole shebang - FrontEnd, Kernel, etc.. Still, that's just me guessing - I know nothing. :)

comment How to speed up Manipulate with Graphics3D
It's smooth and responsive on my 2011 iMac with 12GB RAM, even with PerformanceGoal -> "Quality"... It might help a bit if the box didn't keep changing size...

comment What is going wrong when I save an animation as a SWF-file?
After a bit of googling I learn (to my horror:)) that it is possible to embed SWF inside a PDF and then view the PDF in Adobe reader. But there are all kinds of issues with security and then I stopped reading so this is where I must bow out of the question... Good luck!

I didn't think Adobe Reader could open Flash files... Are you sure that what you want to do is possible?
