[Plugin] Gradient Tools

[huajiet]

Thanks TIG for this very handy plugin!

I'm barely Ruby-conversant but I'm trying to apply some modifications to your plugin. I have a few questions. Do refer to the attached image.

1. I've been able to make the tags report the angle in degrees. How do I limit the tag to 1 decimal point?

2. As you might be able to tell from the image, the plugin is reporting the complementary angle (39.6.. degrees) instead of the actual angle of the pitch (50.3 deg, shown in the measurement box at the lower right). how do we rectify this in the script?

Thanks and regards,
HJ

1. You can fix the number of decimal points in any float [into a string] thus:
   ` num = 1.23456
   dum = sprintf("%.1f", num)

>> "1.2"`

Here the .1f says 1dp and .3f would do 3dp...
To convert that string back into a float:
dum = sprintf("%.1f", num).to_f
There are many options to this Ruby method...

2. You seem to have it reporting the angle of the face's normal, you could just subtract it from 90 degrees ?
   angle = 90.degrees - angle
   then convert the angle from radians to degrees before fixing its dp's...
   angle = angle.radians

1. it works!

2. the problem seems to have righted itself. will keep your solution for reference in case it acts up again.
   #EDIT: it seems the problems crops up when the slope's material is in back face.

Thanks TIG. You're a legend!

The fix for that is to model properly !
Alternatively check norm=face.normal, then norm.z if it's <0 then norm.reverse!
