c# - Finding the points of contact between two convex polygons -


okay, trying create simple 2d polygon physics engine experience. here know (plus sources want find out:

-how determine if polygons intersecting using sat method (http://elancev.name/oliver/2d%20polygon.htm)

-how find normal of collision finding minimum translation axis

-how respond collision via implulse (http://chrishecker.com/rigid_body_dynamics#articles)

there 1 thing keeps eluding me. is, how find points of contact between 2 intersecting polygons. going upload simple picture illustrate mean, seems not able yet.

specifically on is:

-determining sides and/or points colliding

-this includes when polygons intersecting

-getting vector location of each contact point

i appreciate on because have been searching while no luck.

thanks. ~toms jensen

after doing more digging found looking for. found rather written example (in c#) of technique called polygon clipping. method finds contact points in world coordinates. goes through steps , code implementation multiple different situations.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
