White bar under HUD

The resulting 'text' would be unreadable to Oolite in windows XP & Vista too. We've got quite a few threads from people modifying stuff with notepad and not being able to run Oolite properly afterwards.

I've no idea how your copy of notepad doesn't mangle stuff, but the average out-of-the box notepad does. If you look for 'notepad is evil' you should find at least a few of those threads.

Hi KW

You should download Notepad++… it’s free, and for editing code, it’s excellent.
I was using Wordpad, which was okay, but Notepad++ made things a lot easier.
I wouldn’t have worked out how to fix my HUD problem without it.

Check it out.

Regards

Really good question!

On the z axis, +1 is toward the front of the ship, on the y axis +1 is going upwards and on the x axis, +1 is toward starboard (the right hand side if you're looking forward).

I think. 95% sure anyway... :P

Sounds right to me. To answer the question, this makes it left-handed.

For anyone wondering when coordinates got hands, it works like this: if you take your left hand and hold the thumb, forefinger and middle finger at (approximate) right angles to each other, and label the thumb X, the forefinger Y and the middle finger Z, you get a model of a left-handed coordinate system. If X pointed port or Z pointed aft, it would be a right-handed coordinate system. Every possible orthogonal basis in three-space is either left-handed or right-handed, Try it on your fingers, boys and girls!

If you ever see a graphics programmer waving their hand around in a weird claw shape, it may be because they’re trying to think their way through a coordinate transformation. Or it could just be general insanity. Either way, it’s best just to back away slowly and quietly.

I do a lot of this deformed claw movement when explaining the co-ordinate system of real-time 3D models to my students...
