Re: Latex formula support ?

It appears that MathJax has not been implemented on the new server. Would you please do this? Thanks.

Re: camera lens

Ah, someone has stumbled into my area of expertise. (I design lenses for a living.) The first thing to remember is that a really good lens will give you images that look just like a theoretical pinhole camera, but with some depth of field blurring. This means that you can fake a lens pretty easily w...

I agree! :D It wasn't something I was really dying for, but I really appreciate it now that it's available.

Re: Vertex merging paper and SmallVCM

Maybe my recent paper could be an interesting reading on this topic: http://cg.ibds.kit.edu/APPM.php Nice application of error estimation to PPM! I appreciate the realistic assessment of the method's limitations and look forward to seeing these limitations removed. The world (or at least this commu...

Re: Intel Xeon Phi Preferred Pricing - Only $400 per Card ?

assume that it will run at 1ghz with ~ 50 inorder cores (50ghz). multi-threaded codes (non-vectorized) on current hw (dual sb) at 3.x ghz already have (16x3.x ghz >= 48ghz) on out-of-order cores. mp I just read that the Phi has 4 threads per core, or 200 threads, and runs at 1.05 GHz. Given your fo...

Re: Solid angle of triangle

Thank you very much for the reply, much appreciated! One more question, though: As a counterexample to your formula, omega = A/r*r, what if r = 1 and A = 1e6? The correct solid angle in this case (assuming a planar area perpendicular to r) would be approximately pi, not 1e6. Solid angle is the area...

Re: Solid angle of triangle

Thanks for posting this basic question on the "My First" forum. As described in the Wikipedia article, solid angle is defined as the area of the triangle projected onto a unit sphere with its center at the observation point (the point from which your "r" is measured). As a counterexample to your for...
