Plane Shading

To make things look a bit more 3D we need to have a more realistic shading model and add some lights. Types for Lighting Let's add some more types: * Light. Base class for all types of light. Stores the colour of the light (I'm not doing

First Image

Now we have an framework in place we can start on the ray tracing itself. Types for Geometry First step is to add some types to handle geometry: * Point. Represents a point in three dimensions. * Vector. Represents a vector in three dimensions. Although very similar to a point as both

Basic Framework

First step was to get a basic framework in place that can render an image and preview it in the GUI. I added a separate project for all the rendering code, keeping all the display stuff in the GUI project. Helps separate concerns and will make it easier to, for

Rendering

I've decided I need a pet project to practice my coding and to help me (finally!) learn C++. I've been interested in ray tracing for years now, ever since I got my hands on a copy of Imagine for my Amiga 1200. So my initial idea

Unsafe C# - Converting Longs to Byte Arrays

In my previous post on converting enums to bytes I didn't achieve any noticeable speed up using unsafe code, probably because the safe conversion is so simple. What about a more complex conversion that could be done in a different way using unsafe code? A 64-bit long can

Unsafe C# - Converting Enums to Bytes

Whilst working on my Cards project I needed to convert enum values into bytes. The enums in question have ints as their underlying types rather than bytes (even though I could make the underlying type byte everyone pretty much expects all enums will have ints as their underlying type so

Combinatorial Explosion!

The other day I hit a combinatorial explosion when using Haskell's nub function. Whilst I knew it was \( O(n^2) \) I thought my \( n \) (~28,000) wasn't big enough to cause a problem. Turns out it was... Therefore to get a better feel for the
