If you’re not familiar with the PImpl (private implementation) idiom, read this Wikipedia article first. While this is more or less “syntactic sugar” since the templates are expanded during compilation, but I think it makes for cleaner looking code.
One of the things that C++ doesn’t have out-of-the-box is events, which is not necessarily a bad thing. However, with the additions to the C++0x/C++11 specification, we can implement something like an event system found in higher level languages such as C# using relatively easy to use code.
Just launched OpenGLBook.com, a website on learning OpenGL 4.0 programming in online book format. The first two chapters are online, new chapters to be released periodically.
John Carmack, of DOOM, Wolfenstein, and Quake fame, has spoken out on the issue of Direct3D vs OpenGL in an interview with the folks at bit-tech. Check out the article here. Note that Carmack is still using OpenGL in his game engines because of cross-platform compatibility reasons, but prefers Direct3D’s more modern API.
It’s sad to see OpenGL in such a state of disrepair that even a contributor (id Software) to the specification denounces the standard.
P.S. Happy π day.
More news from this year’s Game Developers Conference shows some amazing next-gen graphics from Epic Games through their Unreal Engine. It’s certainly worth checking out the article at Tom’s Hardware right here.
