Hello all, I’m a C programmer with some C++ experience (“C with Classes”+STL anyway; never did implement anything but the most trivial templates) and I’m looking to get stated with D. I figured a good way to do that would be to implement a template library, and it may as well be something I’ll actually use. Here’s what I’m thinking I could make:
• a library for dimensional analysis, like boost::units, and/or • a set of classes for 2-dimensional Geometric Algebra (scalars, vectors, and pseudoscalars/imaginary numbers). (Not to get into a discussion of GA, but its an algebra of scalars, vectors, &c. with dot products, wedge products (related to the cross product, but nicer) and a non-commutative “geometric product”. It’s useful in computer graphics and aerospace control because it has a much nicer approach to rotations than using matrices.) Should I start with D1 for now, or jump right in to D2? Any clues as to which project will get me started with the language faster? —Joel Salomon
