0.10.3

Added

• One world, two views. A terrain in surfaceType="sphere" can hand out its own surface as a globe (terrain.planetSurface()), and <tosi-b3d-planet> draws from it (planet.surface, with relief to exaggerate the heights). The planet you see from orbit is then the ground you land on: the same height function, checked to agree to the centimetre.
• Places. terrain.latLonAt(x, z) and terrain.groundAt(lat, lon), and the pure sphere-map module behind them (ground, latitude and longitude, and direction on the globe, each from the others), so a pin on the globe is a spot on the ground. On the ground +x is east and +z is north.
• Real worlds. <tosi-b3d-planet heightMap colorMap> draws a planet from its maps: the Moon, Mars and the Earth from NASA's and NOAA's data on the CDN (nasa/moon, nasa/mars, nasa/earth, noaa/earth). relief exaggerates the heights, flatSea fills the oceans level, bodyRadiusKm is the real body's radius. The new planet-map module reads the 16-bit height PNGs itself (a browser's own decoding keeps eight bits): loadPlanetMap, decodeGray16Png, mapSurface.
• Weather from orbit. <tosi-b3d-planet clouds="0.5"> puts a shell of cloud inside the air: one coverage dial, winds that reverse with latitude, more cloud along the equator and the storm tracks, and a shadow on the ground beneath. cloudColor, cloudSpeed. planet.storms places up to four cyclones by latitude and longitude, each with an eye, turning the right way for its hemisphere, with lightning inside. Provisional: this is the weather from orbit only, its own field and its own storms; it does not yet agree with the cloud deck and weather cells on that world's ground.
• planet.rootNode is public, for placing a planet.

Fixed

• (behaviour) Planets turn west to east. rotationSpeed spun them the other way, so the Earth ran backwards. A negative rotationSpeed turns a planet the old way (it used to be ignored).
• A planet that has been moved is shaded where it is. The biome shader measured altitude and latitude from the world origin.
• A rotating planet's land no longer shimmers. The biome shader read its noise by world position, so a planet turned under its own climate. On a planet it now works in the planet's own frame, and reads its climate noise in 3D (it was smeared down the sides of the sphere).
• Volcanism on a planet is planet-sized. The volcanic patterns were sized in metres of terrain, so on a globe the regions were one value everywhere (the dial flipped the whole planet) and the plates were a ninth of its width. They scale with the planet now: regions about a twentieth of the way round, plates you can see.
• A planet's air no longer pinches at the poles. Its clouds were 2D noise over latitude and longitude, which converges to a point at each pole and has a seam down the back. They are 3D noise read on the sphere itself now, and in the planet's own frame, so they turn with a rotating planet where they used to stand still while it turned beneath them.
