comment Not getting anti-aliasing with BarChart3D
Is it just BarChart3D that has the problem? Do you get antialiasing on other 3D graphics?

comment Simple problem with Manipulate and Plot
@MichaelE2, it looks like Manipulate has special handling of Out via Manipulate`Dump`resolveOut[]

I can't test it properly, as transparent textures don't work on my system, but to get closer to the original you could try using PlotStyle -> FaceForm[Texture1, Texture2] with Texture2 being a blurred version of Texture1.

Working here too, with version 8. What version are you using @LiaChica?

comment 3D orbits and inaccuracy over time
The jagged lines are because ParametricPlot3D isn't sampling the function finely enough when you go to large values of a. Try using something like {t, Max[0, a-50], a} as the parameter range for the plot. The 50 determines the length of the trail.

@xslittlegrass, try changing the RHS of processHoles to this: polys//.{a___,p:Polygon[x_],q:Polygon[y_],b___}/;Graphics`Mesh`InPolygonQ[p,y[[2]]]‌​||Graphics`Mesh`InPolygonQ[q, x[[2]]]:>{a,Polygon[Join[x,y,{First@x}]],b}

comment Optimizing a simple calculus using a list of matrices - Repeated dot product between a vector and a list of matrices
Note that /@ is just shorthand for Map, not a "pure function version". You can use /@ with named functions as in f /@ {1,2,3} and you can use Map with pure functions as in Map[2# &, {1,2,3}]

comment How can I create a 3D FilledCurve object?
@J.M. you probably noticed that the BezierCurves returned by the decoding function seem to be missing a point (which is why the SplineDegree is too high). I think FilledCurve assumes that each line or curve starts from the end of the previous one, so to get "stand alone" curves you need to prepend each one's coordinate list with the last coordinate of the preceding curve.

comment How can I define a function which is the sum of other functions?
The error here is because C is a protected symbol. Try using lowercase c instead.
