 {{ :blog:galaxy_density.jpg?direct&200|}}
 I'm starting to re-write my Traveller-style star system mapper, and my current step is allowing the creation of a galaxy (or at least, part of a galaxy) from a simple density map. The idea is that you can draw what you want your star map to roughly look like by creating a grey scale image which shows the relative densities of star systems in different areas. Black areas have very few star systems, white areas are densely populated with star systems.
-The mapping software will then take that and generate a distribution of star systems across Sectors of space using this density map. The sample image shows dark regions which represent an underpopulated rift, with a bright densely populated region at the top right.

The sample image shows dark regions which represent an underpopulated rift, with a bright densely populated region at the top right. The probability of any given hex having a star system ranges from 1% to 95%.
 The centre of the image is overlaid with a grid of Sectors that shows the actual generated star systems, with the core Sector (0,0) right in the centre. Using a density map allows the geography of local space to be easily sketched out, and then procedural generation can do the rest.
-A similar technique could be used to define different civilisations, types of stars or level of colonisation.
