 As input to its SSS calculations, FaceWorks uses per-vertex curvature and per-mesh UV scale data.
 
-The `GFSDK_FaceWorks_CalculateMeshCurvature()` function can be used to calculate the curvature values. This function takes the mesh vertex positions and normals, as arrays of floats, as well as the mesh's triangle indices. It estimates the curvature around each vertex, then optionally applies one or more smoothing passes to reduce noise (we use two passes in the sample app). The resulting curvatures are then stored to an output array, one float per vertex. You'll need to store the curvatures in a vertex buffer, and make the interpolated curvature available in pixel shaders where FaceWorks is to be used.

 (Note that in principle, curvature values should change if a mesh animates or deforms; however, in FaceWorks we don't currently provide any support to animate curvature values in real-time. In practice, we suspect it's difficult to notice the effect of changing curvature in common cases, so we recommend simply calculating curvature for the bind pose of a mesh.)

 Note that if the application tries to use curvatures or shadow widths outside of the ranges represented in the textures, we will simply clamp to the edge of the textures; the results will remain plausible as long as you're not too far outside the range.
 
-In the sample app, we used 512x512 LUTs, stored in uncompressed RGBA8. Smaller resolutions can also be used if desired. If compression is necessary, we suggest trying BC6, BC7, or YCoCg in DXT5; DXT1 isn't recommended, since it will create a great deal of banding in the smooth gradients.

 It's important to note that the curvature LUT is generated in linear RGB color space, while the shadow LUT is generated in sRGB color space. FaceWorks expects their texture formats to reflect this, i.e. the curvature LUT should be in a `UNORM` format and the shadow LUT in a `UNORM_SRGB` format. The FaceWorks runtime API will check for this and issue warnings if the shader resource views are not in the expected formats.

 Constant buffer data related to deep scatter can be set by filling out a `GFSDK_FaceWorks_DeepScatterConfig` struct, then calling `GFSDK_FaceWorks_WriteCBDataForDeepScatter()`. The members of `GFSDK_FaceWorks_DeepScatterConfig` are as follows:
 
 -   `m_radius` the desired deep scatter radius, in world units. In other words, the distance light can penetrate through the model. This is used as a Gaussian sigma. In principle, this value should equal the diffusion radius used for SSS, but in practice it's often more aesthetically pleasing to set this to a larger radius, such as 5--6 mm.
--   `m_shadowProjType` the type of projection matrix used for the shadow map. This, and the next two members, are only needed if you're using the FaceWorks helper functions for estimating thickness from the shadow map.
