Well.. there isn't an "Instant Map" button, but I do like the speed with which it handles itself... but... what exactly are the advantages of this over say ... Illustrator?

It came together nicely GP. Although the rivers look a little "hacked" in, but I imagine you are going to clean those up. How in the world do you do .5 pixel??? I didn't think that was even possible since a pixel is the smallest display unit.

Thanks for the doc waldronate, but it didn't answer my question and in fact showed me that I was correct in asking the question. I learned computer technology and how they work before I ever saw raster and vector programs, or rather before I learned how to use them so I always come from the more exacting definitions of things. Thus I already knew that a pixel wasn't a square. Therefore the reason why I asked the question. If Xara is able to produce a half pixel line, that to me, means that it is doing some really interesting math internally or it is fudging what it says is a pixel and thus it prompted my question.Originally Posted by waldronate
That all said, I really liked that article so thank you. I will definitely sock that away for a future debate I'm certain will come up at some point. Point, get it.

It's done the same way that antialiased lines are done. There are many algorithms for doing this task with the simplest being to rasterize the image at higher resolution then sampling down (which is what most graphics cards do for their full-screen AA). There are also algorithms for directly performing antialiasing, with the quick google search http://www.google.com/search?hl=en&q...ed-area+sample turning up a number of good discussions.
My point on the document was that the screen/image representation samples a continuous function and the sampling function determines the minimum visible item.
Oops!
Interesting discussion and document, but I'm afraid I goofed when I said, 1 pixel wide rivers, I meant 1 "point" size rivers and .5 point tributaries.
A "point" is a standard measurement for lines and fonts.
I used the wrong word and created a wonderful discussion on what a pixel really is. Sorry for the goof!

Right, so in the end it still isn't .5 pixel it is actually 1 pixel but set relative to what 'was' "1 pixel". However, I am glad to see that the issue was clarified and makes a whole lot more sense as we look at...
Ah ha! Yes, .5 point (1/144") makes a whole lot more sense to me. It also equates much better with what I was seeing in the map. Those were some seriously big 1 pixel rivers.Interesting discussion and document, but I'm afraid I goofed when I said, 1 pixel wide rivers, I meant 1 "point" size rivers and .5 point tributaries.

GPIt's good to know we are dealing with points and not pixels as that makes a whole lot more sense to me. Thanks for the clarification GP. Oh, and to get this back on topic...
I like the creativity of this map and where it is headed. Very cool background story and it sounds like it would be a blast to play in it.
