3D Lines (Read 1701 times)

3D Lines
Jul 7th, 2005, 5:02pm  
I want to draw some 3D lines. However I have some problems.

1> I want to have strokeweight, so P3D is not my choice?
2> I want the applet to run on browser, so OPENGL is not my choice?
3> Can I add light and shadow effects on 3D lines?
4> Or is there another way to draw lines besides the line() function?

Thanks.

Hi

I'm no expert, but it would be better for you to develop a 3dline class that draws a rectangle for the determined line stroke, length and position; I would also recommend the line be two triangles drawn together as a rectangle, since in some occasions the triangles work much better...

for web, it needs to be p3d (at least for now)

How about drawing a prism instead of a box to represent lines of different thickness?

so finally i use a little trick.

simply draw a few close lines, then it resembles a strokesweight.

I decide to give up on making shadows or lights as it will be very complicated.

here's my work

Very nice visulation of 3D lines, looks good. The keyboard rotation could be smoother I think, its a bit jerky at the moment.
