comment Import 3D Jpeg file
Those are just normal jpg files. I have never heard of a 3D jpeg format, or a 3D pdf format.

comment Finding number of pixels with certain RGB color in an image
@M.R. I don't think that will work in general, will it? You're counting the number of zeros in the blue color channel - but let's say there is a pixel like {50,150,0} then your method will be wrong.

Count is much faster if you tell it to only look up to level 2 instead.

comment Can the increment in Manipulate, Table, Range, etc. be subject to an If statement?
You can join two ranges together: Join[Range[-2, 0, 0.025],Range[0.01, 2, 0.01]]. But you can't use If.

comment Faster use of Condition for a large array (see the example)
@Sumit I see, no that's not possible because the C language can't handle symbolic expressions. It has to receive and return numeric values (or another valid C data type).

comment Faster use of Condition for a large array (see the example)
@Sumit Could you elaborate on what you mean by "store the array as functions"? I will try to answer the question, but I don't quite understand it yet.

comment Is it possible that we can use “+” to add two vectors in polar form?
@SeanPatrick Yes, if you can answer your own question then you are encouraged to do so because we don't like to leave questions unanswered and the answer might help someone in the future. It is also very discouraged to answer questions with comments, for this reason, but sometimes it happens. There is a discussion about this here.

comment Mathematica is getting slow when repeatedly calling an external program
Might be a good idea to send a bug report to WRI and see what they have to say about it.
