Don Syme and several others sent tweets to correct my claims about boxing in F#. I made the mistake of assuming that structs cannot be used as interface implementations without being boxed and allocated on the heap. As it turns out, .NET constraints allo[...]

Finally we will produce some output. And after the work we did so far it will be rather easy. The last “hard” part will be the shading: First (very) simple shading The idea is very simple. A object will reflect … Weiterlesen →

(As usual, I will be sending the publisher a copy of this review to give them and the author a chance to reply to it before I publish it to the blog. Other than including their comments and correcting any factual mistakes they may point out, I don't inten[...]

This time we will have a look at two types that will help us on your way. First I will show you how I implemented a ray-type for representing the most important aspect of ray-tracing itself and then I will … Weiterlesen →
