Re: Beginning to Map (Also Known as KödeBreaker's Mapping Questions)
(thinking of your screenshot and this github page)
Here is a little explanation of parameters r0 and r1:
>note (see attached screenshot): In paxed's online curve tool, parameter r0 is represented by field A, and parameter r1 by field B, r2 = field C, r3 = field D. When you use the cmd version of curve, r0 = r2 and r1 = r3 as long as you do not say "advanced curve settings". So if you want to have a basic curve, er, no advanced settings in this group of settings, in the online curve tool version make the lines "start radius" and "end radius" the same.)
Here is a partial explanation (based on experience just using curve tool) of how a basic curve is created in curve:
Imagine you have a center point. The "start radius" parameter (r0) is a distance, er circle radius, starting from the center point. The "end radius" parameter (r1) says how far to extend this radius. This extended section the radius is the part where you get the brushes. Depending on the values in "beginning angle" (a0) and "ending angle" (a1), part of a circle, a whole circle, or more than a circle is filled by brushes when the radius "sweeps" in this angle space.
>now trying to answer your question itself (still thinking of a basic curve):
The width of one brush in a curve is the difference of the r1 value and the r0 value (r1 - r0). So if you have r0 equal 100 and r1 equal 150, the width of the curve path is this difference: (150 - 100 = 50 units). Then you get a simple equation:
x = r1 - r0 (x is the width of the curve path)
OR: r0 = r1 - x
The real thing do to:
1. Get the width of your straight land.
2. Type r0 and r1 so that the diff is the width of your straight land. (the equation can help)
3. When you get the curve you should have what you want
hope this helps
ps thing I 4got to say in prev post: Donot forget the move tool. You can switch to this tool by an icon in the tool bar of radiant. Basically it is great because it lets you move items without being able to resize them etc. When you are switched to it a box with 3 arrows will appear over your selection. I now realize that the "-" and "+" commands that I tried to show you are merely shortcuts for dragging the vertical axis arrow (z i think, the blue one) using this tool.
