In the application I am developing I havepolygons as show in the picture My data structure is d开发者_运维问答ouble-linked list as follows.
Problem: Suppose you have a collection of points in the 2D plane. I want to know if this set of points sits on a regular grid (if they are a subset of a 2D lattice). I would like some ideas on how to
I\'m writing my own software rasterizer in Java, and I ran into some trouble with it... take a look at a sample image, please:
Say there is a QHBoxLayout and so开发者_如何学Cme widgets in it. How to specify a widget width and hight in the layout, so that while resizing the widget which containes the layout the given width and

I\'m trying to get the button to be right of the label. I set the tuple and am still not sure why it covers the label.
Given a point (x1, y1) and an equation for a line (y=mx+c), I need some pseudo开发者_如何学Pythoncode for determining the point (x2, y2) that is a reflection of the first point across the line.Spent a
So this one is a very difficult one I think, so I\'ll try to make it as clear as possible. So basically, I have geographic datas :
