Some News About the 4th Edition of Physically Based Rendering
We have liftoff.
Let’s Stop Calling it “GGX”
A short plea for getting the naming right.
Sampling in Floating Point (2/3): 1D Intervals
A ramble extending Walker's algorithm to sample arbitrary floating-point intervals, later found to be a rederivation of earlier work.
Sampling in Floating Point (1/3): The Unit Interval
Sampling algorithms can be subtle and tricky, as can be computations that are performed using floating-point arithmetic. This post starts a short series on that topic, starting with the fundamentals: generating uniform random samples between zero and one.
Update: Some Analysis of Physically Based Rendering’s Bibliography
Ending a year of suspense, the numbers are finally in for the fourth edition.
Debugging Your Renderer (5/n): Rendering Deterministically
Making a renderer fully deterministic—the same input always giving exactly the same output—has a few tricky corners that were never all addressed in pbrt until the latest version. Achieving that determinism has all sorts of benefits for testing and debugging.
Debugging Your Renderer (4/n): End-to-end tests (or, “why did that image change?”)
Still in the thick of the task of detecting the presence of bugs in a renderer in the first place, this time the focus is on the value of a large suite of test scenes. Soon soon we will turn to what to do about all of these bugs when we find them.
Debugging Your Renderer (3/n): Assertions (and on not sweeping things under the rug)
Some notes on productively detecting bugs when they occur during the course of rendering and a cautionary tale about what can happen when you ignore runtime errors.
Debugging Your Renderer (2/n): Unit Tests
Returning, now with intention, to write up some thoughts about how to effectively debug a renderer.
