[Closed] maxscript math : find position from angle and distance

you can do it of course using trigonometry but for me it’s easier to do it using matrices.

so… we have original position §
it makes matrix

tm = transMatrix p  

rotate about Z to get azimuth (alpha):

preRotateZ tm alpha

rotate about Y to get elevation (beta):

preRotateY tm beta

and move on distance (d) along X

preTranslate tm [d,0,0]

the final position of the matrix =

 tm.pos  

wow Denis !! It’s so simple, logic and clear, that’s even no fun lol !! many many thnaks !
