Scientific Visualization Studio NASA Released CGI Moon Kit for Free Download. Moon texture which contains different maps such as a color and displacement map that visualizes topography through color. These color and elevation maps are designed to use in 3D rendering software.
The maps are generated from data assembled by the Lunar Reconnaissance Orbiter Camera and laser altimeter instrument teams.
The displacement Map, you can also call heightmap or elevation map. Those taken directly from the moon surface latest (as of spring 2019) gridded data, products of the Lunar Orbiter Laser Altimeter instrument team.
NASA collected Lunar Orbiter Laser Altimeter data from the Geosciences Node of the Planetary Data System. A small subset of the Lunar Orbiter Laser Altimeter or simply LOLA data stored.
The global cylindrical projections at 4, 16, and 64 pixels per degree. Reformatted here as uncompressed TIFF files, in vertical units of either floating-point kilometers or 16-bit unsigned integer half-meters.
Within 3D animation software, an object like the Moon begins as a simple geometric shape, in this case, a sphere. The Texture maps like this you can use to add detail to the 3d model. The color map tells the software how to paint the surface.
The displacement map tells it how to add the shape details that define the lunar terrain. Without those maps, the Moon model is just a smooth, monochrome ball.
These Moon Texture are flat rectangles, the software understands them as maps of a spherical surface and knows how to warp them onto spherical geometry.
