[SOLVED] Rotate placement

Anonymous
Not applicable
This will be hard to explain, hope it makes sense.

When i place object it has defined x, y, z position. So when i need to place in different angle. For example if i rotate 90° i need y= to be x and x= to be y. It get's even more complicated when i need to rotate 45°.
So object get's placed in right position when placed in different angle.
Is there any useful functions to assist this?

Hi,

yes, Geometry module helps with this kind of calculations.
You can use TMRotatePoint for example to rotate a point with an angle:
#include "Point3DData.h" // you need Geometry modul 
 
void RotatePoint (const Vector3D& origo, const Vector3D& axis, double angleDEG, double* x, double* y, double* z) 
{ 
	Geometry::TMRotatePoint (origo.x, origo.y, origo.z, 
								axis.x, axis.y, axis.z, 
								angleDEG * DEGRAD, 
								x, y, z); 
} 
 
// Usage: 
RotatePoint (Vector3D (0.0, 0.0, 0.0), Vector3D (0.0, 0.0, 1.0), 45.0, &x, &y, &z);


This example rotates the coordinates around the Z axis with 45 degrees.

Thanks Tibor.

Couldn't find solution calculated each >0>90>180>360 section coordinates, , long code...

And this takes just few rows Thanks.

Will change to this now.
