Hello!
I'm developing an application which loads an image, and then i have to mark some points with the mouse, above the image. these points should be on a separate layer, ie i don't want to modify image data.
What is the best way of doing this ? I was...

It should be a lot more comfortable to work with than talking directly to directX .
I think WPF have som options for image manipulation.

The best readily available commercial alternative is probably Ceometric's G# , which is neither free nor open-source .
There isn't much out there, unfortunately -- the .NET world seems to suffer from a paucity of good open-source math libraries .

I want to solve geometry problems in online programming contests. But whenever I read them, I just find too difficult. Please suggest some books and resources which I can study computational geometry.

And there's also to solve basic geometry problems quickly, so that it runs within the time limits of the contest, you first.

What are the best tools/libraries (in any language) for working with 2D constructive area geometry?
That is, a library working with more or less arbitrary two dimensional shapes and supplying union, intersection, difference and XOR.
My baseline is the...

Two options come in mind
Cairo Graphics for C Antigrain for C++.
It had a commercial and an open source license last time I checked .
The Computational Geometry Algorithms Library is quite extensive.

Does anyone have some useful beginner tutorials and code snippets for playing with basic geometric shapes and geometric proofs in code?
In particular something with the ability to easily create functions and recursively draw them on the screen. Additional...

If you're willing to use C++ I would recommend two libraries:

Hope that helps
I guess OpenGL.
Tutorials you should be able to have fun with geometry any way you want.

I would solve it with the Flood fill algorithm.
Doesn't look like a geometry problem to me.
This should work.

This is my first time building a strocker, and also doing the rocker geometry.
Does it look ok? Picture is at half lift.

But that is the first.
If it is too loose it can effect geometry some, not a big deal.

So I'm curious about forks and their effect on the geometries and handling of a bike.
If one was to buy a trail bike with, say, a Fox 32 150mm fork on it, it would be safe to assume the bike has been designed around a fork with roughly a 520mm axle to...

Change said geometry and handling no? The 36 has a 545mm A-C vs the 520mm A-C of the 32.
