C++ customIceNode rotation

[jujut]

Hello,

I'm building building a custom ice node in c++, and i 've a problem, i don't know how to do a rotation by matrix

How can i do something like this :

Code: Select all

axis = 1,0,0
angle = 90
matrix (identity)

rotation (Matrix, angle, axis)

newPointPosition = pointposition * Matrix

Thanks in advance for your help

unfortunatly the CRotationf class don't have the GetMatrix3() function like the CRotation one.
There is maybe an easier way, but I'm using this function:

Thanks for the reply

@Ahmidou : Thanks it's work now, i just have to convert the angle into radians and to invert the result matrix.

Below a picture of the compound on which i am working
