The optimal linear direction is -L[3],-L[1],L[3] - assuming the usual sign conventions, storage, etc. where in your case L could be the luminance of the RGB SH vectors. If you are using the coefficients from appendix 10, it turns out to be even simpler - it is just the .xyz coefficients after doing a luminance weighting of cAr/cAg/cAb. That give you the direction. To generate the color of the light, you can simply evaluate the outgoing radiance using the above direction (as in the shader code in the appendix), and that's the color for the light (if illuminating a white material that is the light in the given direction that would give you the same diffuse response as the SH probe.) See the section of the paper titled: "Extracting Conventional Lights from SH" on a technique to solve for both a colored directional light and an ambient light given SH coefficients, but if you are using the storage in appendix 10 it's a bit trickier since the DC term has been "polluted" by</pre> Peter-Pike Sloan 2012-02-03T00:21:51 http://permalink.gmane.org/gmane.games.devel.algorithms/22078 <pre>Looks like you want to normalize the 3d vector made from the basis coefficients (-f[1,1], -f[1,-1], f[1,0]).

You just have N vertices and N-1 edges. One vertex is in the "center" (suppose without loss of generality it's the first one) and then the edges are {1,i} with 2 &lt;= i &lt;= N. "Procedurally generating" such a graph is a single for loop! Considering your reference to cellular textures, what you probably mean are Voronoi diagrams: http://en.wikipedia.org/wiki/Voronoi_diagram If so, there's (reasonably well-known) algorithms for generating it from a set of points. The complexity of both the algorithms and implementation depends considerably on your requirements; if you just need a solution for a low number of points in the plane, that can be done with relatively little code. Higher dimensions require more work, and algorithms with optimal O(n log n) complexity (this is a lower bound for the complexity of algorithms that determine planar Voronoi diagrams!) are more involved than O(n^2) or worse algorithms. -Fabian ---------------------------</pre> Fabian Giesen 2011-09-10T08:51:13 http://permalink.gmane.org/gmane.games.devel.algorithms/22073 <pre>graph theory Not astronomy sorry I've been do some reading and Cellular Texture seams like what I need but the example I've seen are texture-centric -- tom_a_sparks "It's a nerdy thing I like to do" Please use ISO approved file formats excluding Office Open XML - http://www.gnu.org/philosophy/no-word-attachments.html 3 x (x)Ubuntu 10.04, Amiga A1200 WB 3.1, UAE AF 2006 WB 3.X, Sam440 AOS 4.1.2 Wanted: RiscOS system, GEOS system (C64/C128), Atari ST, Apple Macintosh (68k/PPC only)  ------------------------------------------------------------------------------ Malware Security Report: Protecting Your Business, Customers, and the Bottom Line.
