Rich Hickey created a very nice set of persistent collections for Clojure. I started to port them to FSharpx and today I want to present the PersistentVector. The basic idea is that we want to have something like an array but immutable. Vectors (IPersiste[...]

I just realized that I used a technique – projecting a vector on a line given by another vector – in my last post on ray-tracing that I did not justify in any way. Look at this picture: Given vector … Weiterlesen →

Today I want to give some information on the dot-product and provide it’s implementation for out Vector-type in F# (this will be trivial). The dot-product will be very important for our Raytracer-project because of it’s many uses in analytic-geometry. You[...]

As mentioned here I decided to create my own vector-implementation for 3D vectors. I will start with this here and continually extent this type and it’s helper modules as the need arises for our Raytracer. For now I just want … Weiterlesen →
