 * https://www.khronos.org/registry/OpenGL/extensions/ARB/ARB_depth_clamp.txt.
 *
 * When GL_EXT_frag_depth is available we emulate GL_DEPTH_CLAMP by ensuring

 * sending the unaltered screen space z value (using emulated noperspective
 * interpolation) to the frag shader where it is clamped to [0,1] and then
 * written with gl_FragDepth (see czm_writeDepthClamp). This technique is based on:
 * https://stackoverflow.com/questions/5960757/how-to-emulate-gl-depth-clamp-nv.
 *
 * When GL_EXT_frag_depth is not available, which is the case on some mobile 
 * devices, we must attempt to fix this only in the vertex shader. 
 * The approach is to clamp the z value to the far plane, which closes the

// Original FXAA 3.11 shader link: https://github.com/NVIDIAGameWorks/GraphicsSamples/blob/master/samples/es3-kepler/FXAA/FXAA3_11.h

// Steps used to integrate into Cesium:
// * The following defines are set:
//       #define FXAA_PC 1
//       #define FXAA_WEBGL_1 1
//       #define FXAA_GREEN_AS_LUMA 1
//       #define FXAA_EARLY_EXIT 1
//       #define FXAA_GLSL_120 1
// * All other preprocessor directives besides the FXAA_QUALITY__P* directives were removed.
// * Double underscores are invalid for preprocessor directives so replace them with a single underscore. Replace
//   /FXAA_QUALITY__P(.*)/g with /FXAA_QUALITY__P$1/.
// * There are no implicit conversions from ivec* to vec* so replace:
//       #define FxaaInt2 ivec2
//           with
//       #define FxaaInt2 vec2
// * The texture2DLod function is only available in vertex shaders so replace:
//       #define FxaaTexTop(t, p) texture2DLod(t, p, 0.0)
//       #define FxaaTexOff(t, p, o, r) texture2DLod(t, p + (o * r), 0.0)
//           with
//       #define FxaaTexTop(t, p) texture(t, p)
//       #define FxaaTexOff(t, p, o, r) texture(t, p + (o * r))
// * FXAA_QUALITY_PRESET is prepended in the javascript code. We may want to expose that setting in the future.
// * The following parameters to FxaaPixelShader are unused and can be removed:
//       fxaaConsolePosPos
//       fxaaConsoleRcpFrameOpt
//       fxaaConsoleRcpFrameOpt2
//       fxaaConsole360RcpFrameOpt2
//       fxaaConsoleEdgeSharpness
//       fxaaConsoleEdgeThreshold
//       fxaaConsoleEdgeThresholdMi
//       fxaaConsole360ConstDir

//
// Choose the quality preset.
// This needs to be compiled into the shader as it effects code.
// Best option to include multiple presets is to
// in each shader define the preset, then include this file.
//
// OPTIONS
// -----------------------------------------------------------------------
// 10 to 15 - default medium dither (10=fastest, 15=highest quality)
// 20 to 29 - less dither, more expensive (20=fastest, 29=highest quality)
// 39       - no dither, very expensive
//
// NOTES
// -----------------------------------------------------------------------
// 12 = slightly faster then FXAA 3.9 and higher edge quality (default)
// 13 = about same speed as FXAA 3.9 and better than 12
// 23 = closest to FXAA 3.9 visually and performance wise
//  _ = the lowest digit is directly related to performance
// _  = the highest digit is directly related to style

    How is 3D data stored in a 2D megatexture?

    In this example there is only one loaded tile and it has 2x2x2 voxels (8 voxels total).
    The data is sliced by Z. The data at Z = 0 is placed in texels (0,0), (0,1), (1,0), (1,1) and
    the data at Z = 1 is placed in texels (2,0), (2,1), (3,0), (3,1).
    Note that there could be empty space in the megatexture because it's a power of two.

      0   1   2   3
    +---+---+---+---+
    |   |   |   |   | 3
    +---+---+---+---+
    |   |   |   |   | 2
    +-------+-------+
    |010|110|011|111| 1
    |--- ---|--- ---|
    |000|100|001|101| 0
    +-------+-------+

    When doing linear interpolation the megatexture needs to be sampled twice: once for
    the Z slice above the voxel coordinate and once for the slice below. The two slices
    are interpolated with fract(coord.z - 0.5). For example, a Z coordinate of 1.0 is
    halfway between two Z slices so the interpolation factor is 0.5. Below is a side view
    of the 3D voxel grid with voxel coordinates on the left side.

    2 +---+
      |001|
    1 +-z-+
      |000|
    0 +---+

    When doing nearest neighbor the megatexture only needs to be sampled once at the closest Z slice.

The base map features marine bathymetry. Land features include inland waters and roads overlaid on land cover and shaded relief imagery. The map was compiled from a variety of best available sources from several data providers, including General Bathymetric Chart of the Oceans GEBCO_08 Grid, National Oceanic and Atmospheric Administration (NOAA), and National Geographic, Garmin, HERE, Geonames.org, and Esri, and various other contributors. The base map currently provides coverage for the world down to a scale of ~1:577k, and coverage down to 1:72k in US coastal areas, and various other areas. Coverage down to ~ 1:9k is available limited areas based on regional hydrographic survey data. The base map was designed and developed by Esri.
