Now what happens when you release the eraser and start it again, and repeat a few times so that the subsequent erases are working on multiple independent islands? Or did you do that in the example, but there isn't a way to indicate it?
Regardless of the answer, Congrats! Most impressive!

every single mouse move / frame in that gif is such an operation from scratch.... i.e. after each erase, I update my whole object model, possibly splitting shape into shapes. Then do it again on next erase / mouse move.
so yeah, I did it! 
there is also quad tree to save some un-needed computation!

Well done. Now it will be trivial(*) to expand it into an octree and turn the whole thing into a 3D eraser.
(*) Don't believe that. I'm just being evil.

It's true! 
Initially I though this structure was complicated. I kept reading about it and being mystified. But finally I understood... and WTF, this is, in fact, a trivial idea! How could they described it in such opaque terms?!  
In fact, for a while I had I generalised, multi dimensional version of it, but I deleted that code since. It was pointless and complicating thing for no benefit...

Sorry, I mean I had an octree structure.
Manipulating 3D shape and cutting them with a 3D eraser.. errmm.. not there yet! 
No plan either!

Hi All,
My company decided they would move to a new site. The new site required some 'modification' to make it suitable. They are a company that specialises in infrastructure. Some of the site is not ready. The management treat this a 'few' teething troubles, I mean it can't be there first rodeo, So on Monday I have to attend an 'induction to the new office & site' in a place with holes in the walls...

Here in civilized Wales, we fill 'em with glass and call 'em "Windows".

Holes in the wall? That sounds like some newfangled enviro-friendly AC replacement. Just let the wind naturally cool and heat the building as they did for thousands of years!
And I'll stop joking before someone decides to take this into SB territory.

Ancient buildings used to have an AC. The clay wall evaporative AC, that is. You doze the clay wall from the bucket and when the water evaporates through clay pours outside, the energy traded causes inner wall to drop in temperature by tens of degrees causing refrigerator effect

yawn, my take on those is they won't miss one person (make up an excuse later). when actually moving in proper just ask someone else where the coffee machine and toilets are - done.
my favorite though was the fire drills, any fire drill that happened before 12, go to the meeting point so you are marked as present, then it's off to lunch. Even better the afternoon fire drill, check in with the PIC and off home.

Has anyone read the novelisations of Adams' Doctor Who scripts?
The adaptations of Shada by Gareth Roberts (the adventure that was largely lost due to industrial action) and City of Death by James Goss (the best Who adventure ever made, to my mind) were absolutely fantastic. Yet to read Pirate Planet (also by James Goss) but apparently it's based much more on Adams' original ideas than the version that made it to the small-screen, so very much looking forward to that.
There's also a version of "Doctor Who and the Krikkit Men" (Goss again) which was never commissioned for Doctor Who but you'll probably recognise much of it from Life, The Universe and Everything.

Didn't he write a few Doctor Who's?

Yes, he wrote the aforementioned Shada, City of Death and The Pirate Planet.
He was also script editor for a while.

He's just had breakfast at Milliways, and that always messes with your temporal sense of "before" and "after".
Particularly if Pan-Galactic Gargle Blasters wioll haven be on-when involved.

I have Shada sitting on my shelf but haven't taken the time to read it.
|
|
|
|
|
I read Shada. I haven't seen the others.

|

|

I watched Shada - due to the work of some Whovians - as it is now available. Some of it is audio only with still pictures but still good!

There's a more recent version with animated in-fills (they've done similar with missing bits of old Pat Troughton episodes, too). The animation isn't amazing but it works well enough.
It wouldn't surprise me if there'll be yet another version when the new run of classic Who Blu-Ray box-sets reach the appropriate series.
It is a great story, why couldn't the so-and-so's have gone on strike during Timeflight?

Yesterday was the last day of my (contracting) job 
I'm not sad because... Well, if you don't have anything nice to say don't say anything at all... 
To be fair, even though it was hectic and there has been some severe mismanagement, I learned a lot and I'm really going to miss some people (mostly those that complained to management they're letting their best developer go).
Ready for a new customer, which my employer is currently seeking, and which shouldn't be much of a problem for someone with my skills.
And while they're searching I've found a customer (with a fun assignment) for my own which will give me some extra income for the coming month.
(My work situation is kind of complicated )
Exciting times
