Hi

I want to know if it is possible obtein the pitch,roll and yaw

from a SoTransform Node.

Thanks

How about:

----------------------------------------------------------------------

SoTransform *trans;

SbMatrix mat, matI;

float thetaX, thetaY, thetaZ;

trans.getRotationSpaceMatrix(mat, matI);

thetaX = fasin(mat[2][1]);

thetaY = fasin(mat[0][2]);

thetaZ = fasin(mat[1][0]);

1. Euler rotational angles from SoTransform ?

Having a little trouble getting the euler angles from a SoTransform

node. The best I can think of is getting the axis + angles and working

it out by hand..

Is there a better way ? Although quaternions are wonderful, I

desperately need access to the individual angles.

cheers,

Paul

2. Source of more info on scripting languages?

3. CCW euler angles to CW euler angles

4. Input device for precision?

9. Euler angles --> Angle axis vector

10. Which one is better: using SoMultipleCopy node or use SoTransform

11. Writing own SoTransform nodes in Inventor 2.0

12. Calculator between SoTransform-Nodes

13. . Vis. Euler angles on cubic lattices
