Hi,
i’m currently trying to write a interpolate_pose for circle moves but i’m struggling with the calculation of the Center of the Circle which is defined by 3 Poses:
Start : {x0,y0,z0}
ViaP: {x1,y1,z1}
End: {x2,y2,z2}
searching the Center M = {a,b,c}
and given these 3 Points i have 3 equations of a Sphere with 4 unknowns:
(x0-a)²+(y0-b)²+(z0-c)²=r²
(x1-a)²+(y1-b)²+(z1-c)²=r²
(x2-a)²+(y2-b)²+(z2-c)²=r²
which i can’t solve for a,b,c and r. What am i missing? i think it has somethink to do that all 3 Pose Points lie on the equator of the sphere points
