Find window given position, search front-to-back FIXME: Note that we have an inconsequential lag here: OuterRectClipped is updated in Begin(), so wind

Calculates the Fresnel factor using Schlick's approximation

Computes the specular term using a GGX microfacet distribution, with a matching geometry factor and visibility term. Based on "Microfacet Models for R

Generate uniform spherical gaussians on the sphere or hemisphere

Window has already passed the IsWindowNavFocusable()

Returns the extension of the file path

Returns the given file path, minus the extension

Gets the last written timestamp of the file

Retrieve list of range (2 int per range, values are inclusive)

Returns a single 2D point in a Hammersley sequence of length "numSamples", using base 1 and base 2

Check whether the mesh contains normal vectors

Check whether the mesh contains positions. Provided no special scene flags are set, this will always be true

Check whether the mesh contains tangent and bitangent vectors It is not possible that it contains tangents and no bitangents (or the other way round).

Check whether the mesh contains a texture coordinate set \param pIndex Index of the texture coordinates set

Extract the format out of a format string with leading or trailing decorations fmt = "blah blah" -> return fmt fmt = "%.3f" -> return fmt fmt =

Trim str by offsetting contents when there's leading data + writing a \0 at the trailing position. We use this in situation where the cost is negligib
