I really have to have a games night sometime soon. I'm thinking Cranium, rather than Scrabble (it's still in the shrink-wrap; apparently it's not as good a bait as I was led to believe... even the one that requested it hasn't shown up), since Scrabble maxes out at 4 people.
Socialisation is the greatest joy ...!-->!-->
Never did get around to finishing reading Jelle's last big email. I've written two responses already, but I'm only about 1/2 way through it, and the rest appears to be requiring some serious thought to properly answer.
I'm very bad at long emails these days, it's the kind of thing where you know it's ...!-->!-->
Lara (file photo) came by to watch the Grammies (as distinct from grams) on our TV, she's still out there singing and clapping every once in a while, then she switches over to Jerry Macguire and gets all maudlin.
Rosey (again, file photo) is beetling away (just looked that up for spelling and discovered that ...!-->!-->
D'Arcy decided to go to PyCon, so we're going to drive down together. Did some rewriting for the PyCon paper, mostly just expanding the section describing the rationalisation of various object-interactions during the 2.2 type-class unification work. That made the section longer, but didn't actually move me further through the outline. I need ...
After my visit to grams (she won 3:2), came home and got an email pointing out that both Cinemon instances were down. The boxes are still off the network, so there's nothing I can do about it at the moment, but it's somewhat frustrating to have the project sitting offline for this long.
Since I ...!-->!-->
Got distracted from going to bed by the desire to have 4-point coplanar contours properly tessellate. Wound up having to write a new utility function to determine whether a cloud of points is coplanar.
Not a particularly involved function, just note that for all sets > 3 points, you create a vector from A to B, ...!-->!-->
Spent the rest of the evening working on tessellation code, but never did get around to fixing the problem with the Jelle-project tessellation. Instead I realised that I had no test cases for a "combining" tessellation. To understand what that is, consider this shape...
When we render this shape, we want it to look something ...!-->!-->
Sat down to figure out why the shadow-rendering context in OpenGLContext has such problems with the tessellations of Jelle's project. First thing I wound up doing was backing out earlier changes to try to get the VBO extension working, then had to back-port the Python 2.3 PyInt_AsUnsignedLongMask function so that the typemaps for long integers ...
Was just reading through the GLEWpy source-code for the ARB vertex-buffer-object extension. It's basically about the same level as the auto-generated SWIG, or ctypes interfaces. It should work fine, but it doesn't feel natural. Brian's interface looks a lot more natural to me, but it's also a lot more code.
I just have this nagging ...!-->!-->
