I have a completely graphed out blueprint of X, Y coordinates of 8 different multi-pointed shapes on paper. I put these coordinates into an array such as..
Polygon shape1;
int[] shapeOneX = {1,2,3,4,5,6,7,8,9};
int[] shapeOneY = {1,2,3,4,5,6,7,8,9};
shape1 = new Polygon {shapeOneX, shapeOneY, shapeOneX.length};
These coordinates are fake, and not my actual ones but on paper, these coordinates would follow the rules completely on how you would expect vector graphing to look like. When I load this into a Java Applet, the shape does not follow these exact coordinates. They're sometimes close, but not exact, and I need precision for my project.
Does anyone know why, or if there is a different formula you need to use on the coordinates to have it look the same in a java applet? If need more info, let me know.
I understand that starting coordinates for java applet start at the top left 0,0 then expand from there. I guess my questioning is,I have the understanding that "vector" cords start at 0,0 as a Mid point. I don't know much about graphing. So... my shapes are being created from a vector style, but being "placed" into an applet which has a 0,0 top left origin. Which is fine, I have the tools to adjust them where I need to put them. I just can't get them to create the shape I actually graph on paper. Do I need to graph on paper from a 0,0 top left origin and only create positive X, Y variables?
Another Edit-- I've noticed that when it draws onto the applet, it draws it almost mirrored as well. In other words, (x) goes right, (-x) goes left. That's normal. But (y) goes DOWN, and (-y) goes UP.. That doesn't seem normal HMM.. Confused.
Final Edit(probably) -- Well I was right about the Y axis being mirrored. Why? I don't know. But it has allowed for me to redesign some coordinates. I am currently under the impression that line borders were so thick that connected each vertex, that they reformed the shapes into a blob of junk. Because of the overlapping borders. It was hard to see where each vertex actually truly was. I also had to increase the values of my (x,y) coordinates in order to compensate for the size difference. Which I have probably near 100 or so different (x,y) combinations that I will need to re-do because of this... I really wish there was an easier answer. I am open to any and all suggestions, meanwhile I will plug away at remapping this. Thanks everyone who has, or continues to contribute.
For Example.. This first was the orignal coordinates:
int[] wallX = { -2,-2,-1,-1, 2, 2 };
int[] wallY = { -1, 3, 3, 0, 0,-1 };
And then the new WORKING coordinates I found to work are:
int[] wallOneX = { -2,-2, 1, 1, 10, 10 };
int[] wallOneY = { 4,-8,-8, 1, 1, 4 };
So thats the difference of numbers needed to create the same shape from paper, into the java applet. I don't really see a pattern or anything to recreate it for all my other ones. So I don't know.
