+# ellipsoid.maple -- compute equations for offset ellipsoid setup
+# $Header$
+> 
+#
+# ellipsoid has center (A,B,C), radius (a,b,c)
+# angular coordinate system has center (U,V,W)
+#
+# direction cosines wrt angular coordinate center are (alpha,beta,gamma)
+# but Maple predefines gamma = Euler's constant, so we use (xcos,ycos,zcos)
+# instead, i.e. a point has coordinates (U+xcos*r, V+ycos*r, W+zcos*r)
+#
+# then the equation of the ellipsoid is
+#	(U+xcos*r - A)^2     (V+ycos*r - B)^2     (W+zcos*r - C)^2
+#	-----------------  +  ----------------  +  -----------------  =  1
+#	        a^2                  b^2                   c^2
+#
+# to solve this, we introduce intermediate variables
+#	AU = A - U
+#	BV = B - V
+#	CW = C - W
+#
+> eqn := (xcos*r - AU)^2/a^2 + (ycos*r - BV)^2/b^2 + (zcos*r - CW)^2/c^2 = 1;
