Lots of subtle improvements in XVG yesterday.
For example, it can now create n-gons automatically at the user’s request.
Time now to think about how XVG is going to turn into a bona fide SVG generator for geometric design.
So far I have been relying on two global 2-dim JS arrorys to keep track of things: the angles array and the markers (ie, the blue dots) one.
Time now to build more intelligence into the app.
I am thinking of something along these lines.
class vector (object) {
public:
methods…
private:
methods…
internal data:
head (aka marker)
tail
direction
magnitude
center
angle}
class chain (double linked list) {
public methods
…
private:
marker 0 // previous
marker 1 // current
marker 2 // next
}
class marker {
public:
methods… inlcuding clone()
private:
on-off switch // XVG connects ON markers at user’s request
coordinates
color
etc
}
Will keep y’all posted.
Meanwhile, here is another screenshot of what working with XVG in full screen mode currently looks like. I might add some sort of ability that is non modal (modal = uncool) that allows users to do stuff other than just click and connect.
A dream would be contextual menus and panels, a la Sketch.
Dream on.
A continuing problem is the SVG painter’s approach to layering. What this mean is that u have to be real delicate to grab the marker and not a connecting line that overlays the marker, when you want to connect it to a different marker.
A crude solution would be to make the markers bigger. I am going to have to think about this some, like I need to disguise even further the way SVG works. (Note: clicking again on the Mark button solves the problem.)
