This interface allows gnuplot to be controlled from C++ and is designed to be the lowest hanging fruit. In other words, if you know how gnuplot works it should only take 30 seconds to learn this library. Basically it is just an iostream pipe to gnuplot with some extra functions for pushing data arrays and getting mouse clicks. Data sources include STL containers (eg. vector), Blitz++, and armadillo. You can use nested data types like std::vector<std::vector<std::pair<double, double>>> (as well as even more exotic types). Support for custom data types is possible.

This is a low level interface, and usage involves manually sending commands to gnuplot using the "<<" operator (so you need to know gnuplot syntax). This is in my opinion the easiest way to do it if you are already comfortable with using gnuplot. If you would like a more high level interface check out the gnuplot-cpp library (http://code.google.com/p/gnuplot-cpp).

The most successful sci-fi designs anchor themselves in reality. A good rule of thumb used by entertainment designers is the 70/30 rule:

Use varying line weights to indicate separate armor plates. Thicker lines indicate deep gaps between major structural components; thinner lines represent minor maintenance hatches.

For those looking to master the art of speculative design, the highly acclaimed book Sketching from the Imagination: Sci-Fi serves as an indispensable masterclass. Published by the renowned 3DTotal Publishing, this 320-page compendium provides an unfiltered look into the minds and sketchbooks of 50 visionary artists.

Each artist is given a dedicated section to present a showcase of images from their personal sketchbooks. More importantly, they accompany their work with enlightening commentary, sharing not just the "what" but the "why" and "how" behind their creations. The list of featured artists includes:

Concept art is the bedrock of modern filmmaking, video game development, and graphic storytelling. At the heart of this creative industry sits the ability to build worlds that do not exist out of thin air. For artists looking to master this skill, Sketching from the Imagination: Sci-Fi by 3dtotal Publishing has become an essential reference.
