30.2.4 PlaneMod

Function

$f = \sin\left(\theta\right)\cos(\phi)x + \sin(\theta)\sin(\phi)y + \cos(\theta)z + d$

Modified implicit plane function defined by its normal direction.

Number: 3

Names: theta, phi, d

Meanings: theta = unknown, phi = unknown, d=unknown

Lower Bounds: $\theta\ge0$ , $\phi\ge0$

Upper Bounds: $\theta\le\pi$ , $\phi\le2\pi$

$a=\sin(\theta)\cos(\phi)$
$b=\sin(\theta)\sin(\phi)$
$c=\cos(\theta)$
