pc is the single argument to the function created by scalingtransform

@Phily ImportString is still a good approach vs doing your own parsing.

comment Progress Indicator & sums
that is just plotting all the points. It gets a bit hairy if you want to show only the points in the current recursion.

comment Progress Indicator & sums
..you can make this work nice, forgoing the adaptive evaluation, by using MaxRecursion -> 0, PlotPoints -> 200

comment Progress Indicator & sums
Plot adaptively evaluates x in a non sequential order. Without knowing a priori how many evaluations will be needed I see no sensible way to make the progress indicator work

comment Construct a function that can generate a geometry by extruding a section
I agree this is not a duplicate since he seems to want an analytic representation of the solid. Unfortunately I think the answer is simply 'no there is not a straightforward general approach'

comment Detect each polygons in an image
In case you don't realize the fuzziness at the edges is an artifact of jpeg compression. If you have the original to work with you'll have an easier time of it.

yet somehow Wolfram supports linux which isn't "supported" by anyone.

comment How do I plot points on a sphere using spherical coordinates?
ListPointPlot3D works with the matrix just fine - use instead of Graphics3D[Point[..]] if you want the labeled axes on the figure. ( and you likely needyto specify BoxRatios to make it look right )

comment how to find intersection between a parametric trajectoy and a point
Chop removes a numerically negligible complex part. Hitting a point in 2d isn't formulated in terms of 'zero crossings' so i cant see how you could use the methods in the link. You need to find minimum distance to the point and if you need to automate it you need to put in a check that the minimum you find is really zero.

comment Fitting the Plot by fourier Series of either sine or cosine
could be a mistake.. you can play with different numbers to see how well it converges.
