Is there a bug in OgreMath?

[myStupidNickname]

I've look all over the forums and I can't find anything on this. I'm having a problem with the trig functions on OgreMath.

Code: Select all

Real someReal = 0.999903;
Radian someRadian = Math::ACos(someReal);

The expected result is that someRadian would equal 0.0139568 but I keep getting 0.799663 which is what I would get if I took the inverse cosine of a degree value(before everyone races to load Windows Calculator ) . I can't figure out why since the way I read the code for Math::ACos is that it uses math.h's acos(i tested, this does return radians) and then uses the result to construct an instance of a Radian. It may be a problem with the Radian code(though I don't see a problem in the line of code in the Radian constructor) since I get the same result if I copy the Math::ACos code into mine.

Has anyone ever encountered this problem before? I am using Code::Blocks with the VC++ Toolkit 2003 version 1-0-2 of Ogre. I also encountered the same problem with gcc and Dev-Cpp. Thanks!

Oh, and I'm making a MMORPG that will be WAY better than Everquest...just kidding, its my first time posting here and I thought I was supposed to say that.

The second post is not needed.

see that.
Ogre::Radian::valueRadians()

Code: Select all

Real someReal = 0.999903; 
Radian someRadian = Math::ACos(someReal); 
someRadian.valueRadians(); // give the real value in radians

Thanks BlasterN. Now I know my problem is not Ogre's interpretation of Radians but my interpretation of trigonometry(which is not surprising). And the second was kind of needed if only because I suffer from the delusion that I'm funny.

Hey, Welcome to Ogre!
I find it funny

We have been teaching bad habits to the people... Maybe we should put some 'Making an MMORPG is NOT required! Everybody will be taken serious.' on the forum's front page.

Since I'm not actually making one, I actually feel a little left out. It's like maybe the other newbies know something I don't or maybe there's a wiki entry I skipped over.

I think it's the other way around.

Edit: Oh yeah, you did miss, not a wiki entry, but this fantastic tool... Damn, temas closed his blog. He once had a nice one-click MMPORG generator tool for Ogre.

You mean this ? :

May I have a copy of the generator?
