Rotate a vector no more than N degrees
|
A 3D vector [0,1,0] perpendicular to plane XZ.
I want to rotate the vector "no more" than N degrees (N>=0,N<=180) so the angle between the transformed vector and the up vector is <= N.
Let's say N=45.
Given 2 rotation matrices mX.rota... |

Set / Get 2D Vector Angle
|
I'm sure this will be trivial for someone, and I'd appreciate your answer.
1. What I need is to calculate x,y for an angle with the range (0 -> PI*2).
2. Also I need to calculate the angle between the same range 0 to PI2 using x, y.
I'v... |

PHP alternative to mysql_real_escape_string

I need to create a PHP function that does the same thing as mysql_real_escape_string. The reason being that I need to use this function more than I actually need to connect to the database.

Filter db output
|
Hi,
I'd like to ask your opinion. I have a strict filtering policy for all user input on my php site, some of that data is inserted into my database. I wonder should I still filter data coming from mysql before displaying it? Why?

MFC Tool Window Style

Scratch that!
I'm using a special child frame class for the tool windows and loading a child window with all controls onto it. Also I'm modifying the style to WS_EX_TOOLWINDOW. |

Set / Get 2D Vector Angle

I think that cleared everything up. Thank you.
Set is now:
y = cos(a); x = sin(a);
Get is now:
a = atan2(x, y);
if(a < 0)
{ a+PI2;
}
Edit.. You beat me 2 it Admiral. Thanks for your help. I see you have x,y in the proper places. I'... |
