Hexagon Grids

Here you can find my Hexagon Grid project. It doesn't currently have any plans to be used by me, but it was a fun learning process. I based the code from an article that I found at http://www.codeproject.com/KB/graphics/ ... part1.aspx.

It's fairly easy to use, with the code being:

Code: Select all

#include "Main.h"
#include "Hexagon.h"
#include "Grid.h"

#pragma comment(lib, "irrlicht.lib")

int main()
{
	IrrlichtDevice* dvc = createDevice(EDT_OPENGL, dimension2d<s32>(800, 600), 32, false, true, true, 0);
	IVideoDriver* drv = dvc->getVideoDriver();

	dvc->setWindowCaption(L"Hexagon Grid");

	Grid grid;
	grid.create(7, 7, 35); // 7x7 grid - side of hexagon is 35 units. 7 is max, see grid.h for why. I'd like suggestions here

	while(dvc->run())
	{
		drv->beginScene(true, true, SColor(255, 0, 0, 0));
		grid.draw(drv);
		drv->endScene();
	}

	dvc->drop();
	return 0;
}

Looks easy enough, right?

I might have a 3d implementation up soon.

I used this kind of hexagonial grid in one of my Nintendo DS Projects. Its really useful for Touchscreen keyboards

I'd been up for far too long and couldn't remember how to do that. Thanks!

Sounds interesting. All that DS stuff is beyond me, but hopefully it'll help anyone looking to get into it.

well if it was 3d or faked 3d it would remind me of this

I remember that game. Used to be one of my favorites, but I forgot it used hexagon grids for that sort of thing. Maybe this'll get more application than I'm expecting.
