Finding rotation angles from a normal
|
Hello, sorry if this is a newbie question, but it's really puzzling me since I have a very modest math knowledge.
I would like to know or to see an example of how to calculate the 3 rotation angles for a vertex point, knowing its normal.
For ex... |

Help needed for parsing algorithm

The following code works perfectly if both files are .cpp

int myVar;
//client.cpp
extern int myVar;
void test()
{
myVar=99;
}
But if I rename clien... |

C++ multi-level tree search

Hi, I'm not very experienced with C++ and here is a screenshot that shows what I'd like to accomplish: I'd like to be able to use a recursive function or an automated mechanism that can find all the children values of a certain node.
For example:

VC++ : change menu text colors
|
This seems to be a quite difficult task, and I could not find any reference or sample.
I know how to change the background color of a window menubar, but how can you change the text color as well ?
Is it possible ? |

Hi, I'm developing a small application on an iPhone, which has a 16 bit depth buffer. I obviously ran into z-buffer fighting when rendering the terrain.
Reading some at www.opengl.org, they advise to use a multipass tecnique:

Basically is a terrain with some objects deployed on it.
First problem: object are deployed vertical to ground plane (red ones), while I'd like to have them p... |

Finding rotation angles from a normal

Thanks for your answer Bob. What if I'd not care about the rotation angle around the normal, and I'd just like to gather the other two ?

C vs. C++ extern

Well I think it's better if I start to convert those C files into C++: I guess mixing both C/C++ can be done but in my case, having a quite complex project, it's better to uniform sources. |
