A New Dimension In the last post, I’d shown how a small tweak to Imageworks’ multiple-scattering Fresnel term, $\color{brown}{F_\mathrm{ms}}$, brought their approximation closer to the reference solution of Heitz et al. However, there was still a niggling difference at high roughness, most noticeable under uniform lighting: Figure 1: Furnace test, with roughness $\in [\frac{1}{8},…
A Random Walk to the Ground Truth In the last post, we saw that significant energy was being lost due to the common single-scattering limitation of microfacet-based shading models: An intuitive way to think about this is that these BRDFs are only modelling direct lighting (= single scattering) of the microsurface heightfield. Indirect lighting (= multiple scattering) is not simulated, and that is…
Introduction As part of the Physically Based Shading Course at SIGGRAPH last year, Christopher Kulla and Alejandro Conty presented the latest iteration of Sony Pictures Imageworks’ core production shading models. One area of focus for them was to improve the energy conservation of their materials; in particular they wanted to compensate for the inherent lack of multiple scattering in common…

2pm, Wednesday 13th August. Located in the west building, rooms 211-214. We’re back once again with the Physically Based Shading (in Theory and Practice) course at SIGGRAPH! You can find the details on the new course page, but I’ll copy the schedule here, for your convenience: 14:00 Physics and Math of Shading (Naty Hoffman) 14:20 Understanding the Masking-Shadowing Function (Eric…

This is a DX11 followup to an earlier article on quad ‘overshading’. If you’ve already read that, then feel free to skip to the meat of this post . Recount As you likely know, modern GPUs shade triangles in blocks of 2x2 pixels, or quads . Consequently, redundant processing can happen along the edges where there’s partial coverage, since only some of the pixels will end up…
As with last year , I’m gathering links to SIGGRAPH content, to complement Ke-Sen Huang’s invaluable Technical Papers list . Please let me know if you have anything to add to the list.
+ = By Colin Barré-Brisebois and Stephen Hill. The x, why, z It’s a seemly simple problem: given two normal maps, how do you combine them? In particular, how do you add detail to a base normal map in a consistent way? We’ll be examining several popular methods as well as covering a new approach, Reoriented Normal Mapping, that does things a little differently. This isn’t an…
+ = I’ve added a new article, Blending in Detail, written together with Colin Barré-Brisebois, on the topic of blending normal maps. We go through various techniques that are out there, as well as a neat alternative (“Reoriented Normal Mapping”) from Colin that I helped to optimise. This is by no means a complete analysis – particularly as we focus on detail mapping – so we might…
Lately I’d been getting increasingly frustrated with the limitations of WordPress(.com), so I longed for a change. With the Easter weekend, I finally had a little extra time and energy to make the switch to Octopress, plus a dedicated web host. Hopefully that’ll encourage me to start posting again, or at least remove one major grumble. I’m also looking forward to such liberties as the ability to…
Wrapping Paper I first tinkered with SH wrap shading (as described in part 1 ) for Splinter Cell: Conviction , since we were using a couple of models [1][2] for some character-specific materials. Unfortunately, due to the way that indirect character lighting was performed, it would have required additional memory that we couldn’t really justify at that point in development. Consequently,…
A while back, Steve McAuley and I were discussing physically based rendering miscellanea over a quiet pint – hardly a stretch of the imagination, since we’re English 3D programmers after all! Anyway, it turned out that we both had plans to write up a few thoughts in relation to wrap shading , and, following some gentle arm-twisting, Steve has posted his. I suggest that you go and read that…
Figure 1: Major axes for original (left), swizzle (mid) and perpendicular (right) vectors. Introduction Two months ago, there was a question (and subsequent discussion) on Twitter as to how to go about generating a perpendicular unit vector, preferably without branching. It seemed about time that I finally post something more complete on the subject, since there are various ways to go about doing…
I recently added two of my existing publications, one about high performance dynamic visibility and the other on how to display pixel quad overshading in real-time on Xbox 360. The first of these was originally published in GPU Pro 2. Unfortunately, I missed some errors that crept into the typeset version, so I was pleased to finally correct those and I took the opportunity to rework a few…
This is a tweaked version of a journal entry for the Microsoft Game Developer Network, that’s been cleansed of any non-public Xbox 360 specifics. If you’re a registered developer, I encourage you to check out the uncut edition available there, for full implementation details. Introduction PIX for Xbox 360 is an excellent application for deep analysis of a rendered frame. But, like a…
Stephen Hill and Daniel Collin 1. Introduction With the complexity and interactivity of game worlds on the rise, the need for efficient dynamic visibility is becoming increasingly important. As luck would have it, this article covers two complementary approaches to visibility determination that have shipped in recent AAA titles across Xbox 360, PS3 and PC: Splinter Cell: Conviction and…
Both HPG and SIGGRAPH were a blast and I’m intending to write up a full report soon, but here are some links to conference content in the meantime. If you have any additional sources, please let me know in the comments section and I’ll update the post accordingly.
'You see, in this world there's two kinds of people, my friend: Those with loaded guns and those who dig. You dig.' — Blondie. Saddle Up! In this post, I’ll be reviewing some existing methods for attaining well-behaved specular lighting. I’ll also cover a simple twist on these that fits better with current game lighting approaches and console memory constraints. What do I mean by…
