Test Galaxy Map

This is a super simple project for generating galaxy maps suitable for a 2D game. No efforts have been made to make the generation process efficient, and tweaking generation settings must be done by manually editing constants in the js file.

Configurables

Canvas Configs

• width: width of the canvas. Needs to be kept in sync with element width declared in the html
• height: height of the canvas. Needs to be kept in sync with element height declared in the html

Rendering Configs

• RENDER_AXIS: enable/disable rendering of the x and y axis
• RENDER_ARMS: enable/disable rendering of the galaxy arm guidelines
• RENDER_CLUSTERS: enable/disable rendering star cluster borders
• RENDER_STARS: enable/disable rendering of all stars
• RENDER_STARS_ARM: enable/disable rendering of filler stars in the arms (does not effect cluster stars)
• RENDER_STARS_GENERAL: enable/disable rendering of the stars between the galaxy arms

Star Density Configs

Density values here represent N/1000 stars/pixel for a given region. Finding a comfortable balance here is very much a manual effort.

• MIN_STAR_DISTANCE: Minimum number of pixels between any two stars
• STAR_DENSITY_GENERAL: Star density for stars between arms of the galaxy
• STAR_DENSITY_ARM: Star dentity for stars in the galaxy arms, but not in the star clusters
• STAR_DENSITY_CLUSTER_MIN: Minimum boundry for star cluster density
• STAR_DENSITY_CLUSTER_MAX: Maximum boundry for star cluster density

Images

The following are a couple examples of the resulting maps.

This first image is with the default settings
