Trying to draw curves but they pop out of the page

in Programming Questions • 11 months ago

Hello, I'm making a program that displays protein itneractions and I have basically a circular graph with curves going between various arcs, as seen here http://puu.sh/1gRI7.png (I didnt embed it because it is quite a large screen shot as I have a very high resolution screen). Now if you watch the video here http://puu.sh/1fff5.mov you can see that when i rotate the graph, the curves are 3d and stick out of the page. I need them to be 2d and so when you rotate it, they stay flat to the page and rotate with the graph but flat. I've tried many different things but can't get it to work, any suggestions? :(

Here is the drawing part of the code

float randX = 0.1;
float randY = 0.1;
for (Heading H: Mappings.values())
{
randX = (randX+(10));//*(-1);
randY = (randY+(15));//*(-1);
noFill();
curve(expcoords.Coordx+randX, expcoords.Coordy+randY,expcoords.Coordx, expcoords.Coordy, H.Coordx, H.Coordy, H.Coordx+randX, H.Coordy+randY);
}

are you using P2D or OPENGL or what...?

I'm not sure, I never defined anything like that.

Under size() you should have something like size(width, height, RENDERER); if you just have size(width, height); I believe you are using P2D as a default.

" if you just have size(width, height); I believe you are using P2D as a default."
No, default is JAVA2D.

I don't see the lines "going 3D", you just have a problem with the parameters to keep them tight, which we cannot fix with your little snippet.

Yeah as you said the default was JAVA2D. I was experimenting with the different renderers and these are even worse looking

P2D: http://puu.sh/1kSC7

P3D: http://puu.sh/1kSCx

Here is the full code http://pastebin.com/HaChKp9L for that file

I need them to bow out like that so you can see all the lines but i also want them to stay flat and look the same when rotating them
