Planet Concept #1
(This is a cross-post from my devlog on tumblr.)
This is a concept image for a procedurally-generated gas-giant-like planet in the game.
Right now, planets are rendered as a single circle filled with a radial gradient that is offset from its center. This is pretty effective for giving the illusion of a sphere, but it’s a boring non-textured sphere.
Currently what I’d need to add to the game would be an extra layer or two of inverted radial gradients for “atmosphere effects” (the blue lighting) and an overlay texture that is either canned or also procedurally-generated. When I figure out how to do this I’ll make a technical post explaining my technique.
Oh and yeah, I realize that the lighting is unrealistic — gas giants have clouds that align perpendicular to their axis of rotation, which corresponds to their axis of orbit around their star. Unless the axis of the planet got thrown off bigtime — which does occasionally happen with planets like Uranus — it doesn’t really make sense. Our camera would have to have been rotated, too.
That reminds me; while I wont be going to great lengths to make the game universe realistic, I’ll try to keep them somewhat-correct. More on that later.”/>
