+	// The final logarithmic depth formula used here is adapted from one described in an
+	// article by Thatcher Ulrich (see http://tulrich.com/geekstuff/log_depth_buffer.txt),
+	// which was an improvement upon an earlier formula one described in an
+	// Outerra article (https://outerra.blogspot.com/2009/08/logarithmic-z-buffer.html).
+	// Ulrich's formula is the following:
+	//     z = K * log( w / cameraNear ) / log( cameraFar / cameraNear )
+	//     where K = 2^k - 1, and k is the number of bits in the depth buffer.
+	// The Outerra variant ignored the camera near plane (it assumed it was 0) and instead
+	// opted for a "C-constant" for resolution adjustment of objects near the camera.
+	// Outerra states: "Notice that the 'C' variant doesn’t use a near plane distance, it has it
+	// set at 0" (quote from https://outerra.blogspot.com/2012/11/maximizing-depth-buffer-range-and.html).
+	// Ulrich's variant has the benefit of constant relative precision over the whole near-far range.
+	// It was debated here whether Outerra's "C-constant" or Ulrich's "near plane" variant should
+	// be used, and ultimately Ulrich's "near plane" version was chosen.
+	// Outerra eventually made another improvement to their original "C-constant" variant,
+	// but it still does not incorporate the camera near plane (for this version,
+	// see https://outerra.blogspot.com/2013/07/logarithmic-depth-buffer-optimizations.html).
+	// Here we make 4 changes to Ulrich's formula:
+	// 1. Clamp the camera near plane so we don't divide by 0.
+	// 2. Use log2 instead of log to avoid an extra multiply (shaders implement log using log2).
+	// 3. Assume K is 1 (K = maximum value in depth buffer; see Ulrich's formula above).
+	// 4. Add 1 to each division by cameraNear to ensure the depth curve is shifted to the left as cameraNear increases.
+	// For visual representation of this depth curve, see https://www.desmos.com/calculator/lz5rqfysih
