 ====== Projection ======
-THIS position should be used for a brief introduction (max 2 sentences!) of the logic, stating WHAT and WHY it is doing something.
+This logic projects a 3D volume into 2D space. The resulting stack of 2D references can be used as references for an [[eyes:logics:alignment|]].
 ===== Usage =====
-Here, a general/generic description of HOW the logic is USED should be given. Try to be as general as possible, but also mention prerequisites, restrictions, advantages, requirements which are specific of this logic. Basically everything the user needs to know to successfully use this logic.
+Any 3D volume can serve as input for this logic projection is performed on a HEALPIX grid or with a certain angular distance.
-===== Example ====
-Here, a very specific example should be given/described. In the future, this can be supported by screenshots etc.. For the moment, give an example easy enough for the user to understand, but specific enough to elaborate why a given parameter is a good set for this very situation.
-===== Modes/Processes =====
-==== thisIsTheNameOfMode1 ====
-Here, a short introduction for the given mode should be placed. Again, state WHAT and WHY this mode us useful in not more than 2 sentences.
+===== Mode =====
+==== Fourier ====
+Projects by taking 2D slices from the Fourier transform of the 3D volume

-===== Concept =====
-In this paragraph, the "HOW a logic works under the hood" and WHY someone should use it can be elaborated with higher detail. Describes a scenario in an image processing workflow where this logic can be used to solve the resulting problem. Also, wikipages, publications or anything else describing the theory behind an algorithm should be linked here, if applicable.
