Global Illumination in the Game Industry Part I

Sunday, December 12,2010

The history of global illumination in games is rather short. At the beginning there were light mapping tools that were able to store radiosity data in a light map. The disadvantages of this kind of techniques are - hard to mimic a 24 hour cycle - storing those light or radiosity maps on ...

Edge Detection Trick

Saturday, March 20,2010

Benualdo posted in the Light Pre-Pass Thread a cool trick on how to detect edges to run a per-sample shader for MSAA (just in case centroid sampling doesn't work for you). Here it is: ---------- another stupid trick for edge detection pass on platforms that support sampling the MSAA surface with linear ...

MSAA on the PS3 with Light Pre-Pass on the SPU

Friday, July 03,2009

In the previous "MSAA on the PS3" thread Matt Swoboda jumped in and mentioned that they implemented MSAA on the SPU in the Phyre Engine. I knew that they implemented the Light Pre-Pass on the SPU but I completely forgot that they also had a solution to do MSAA on ...

MSAA on the PS3 with Deferred Lighting / Shading / Light Pre-Pass

Wednesday, June 17,2009

The Killzone 2 team came up with an interesting way to use MSAA on the PS3. You can find it on page 39 of the following slides: http://www.dimension3.sk/mambo/Articles/Deferred-Rendering-In-Killzone/View-category.php What they do is read both samples in the multisampled render target, do the lighting calculations for both of them ...

Multisample Anti-Aliasing

Saturday, June 13,2009

Utilizing the Multisample Anti-Aliasing (MSAA) functionality of graphics hardware for deferred lighting can be challenging. Nicolas Thibieroz wrote an excellent article about MSAA published in ShaderX7 with the title "Deferred Shading with Multisampling Anti-Aliasing in DirectX10". The following figure from the ShaderX7 article shows how MSAA works:...

Deferred Lighting / Particle System

Saturday, May 23,2009

Here is a shot of a GPU based particle system with lights attached to each particle. I used Emil Persson's example Deferred Shading program as a basis to implement a Light Pre-Pass renderer with 4k lights and 4k particles. It runs fairly well on a GeForce 9600 GT here:...

Light Pre-Pass: Knee-Deep

Monday, May 18,2009

Several companies adopted the Light Pre-Pass idea, modified it or came up with similar ideas:

Crytek: they call it Deferred lighting contrary to Deferred shading. The technique is mentioned in the new Cry Engine 3 presentation here Garagegames in their new Torque 3D engine currently in beta. Read the article from ...

Light Pre-Pass: More Blood

Sunday, September 28,2008

I spent some more time with the Light Pre-Pass renderer. Here are my assumptions: N.H^n = (N.L * N.H^n * Att) / (N.L * Att) This division happens in the forward rendering path. The light source has its own shininess value in there == the power n ...

Calculating Screen-Space Texture Coordinates for the 2D Projection of a Volume

Tuesday, September 09,2008

Calculating screen space texture coordinates for the 2D projection of a volume is more complicated than for an already transformed full-screen quad. Here is a step-by-step approach on how to achieve this: 1. Transforming position into projection space is done in the vertex shader by multiplying the concatenated World-View-Projection matrix. 2. ...

Light Pre-Pass Renderer

Monday, March 17,2008

In June last year I had an idea for a new rendering design. I call it light pre-pass renderer. The idea is to fill up a Z buffer first and also store normals in a render target. This is like a G-Buffer with normals and Z values ... so compared to ...
