<p>A dihedral angle is the angle between two planes.</p>
|
|
<p>To calculate this angle, you can follow these steps:</p>
|
|
<p>1. <b>Calculate the equation for each plane</b>. It will be in the form:</p>
|
|
<p align="center"><img src="images/plane-formula.png" width="205" height="22" alt="plane formula" /></p>
|
|
<p>2. Then, knowing the equation of the two planes, you can <b>calculate the dihedral angle</b>:</p>
|
|
<p align="center"><img src="images/dihedral-angle-formula.png" width="342" height="58" alt="dihedral angle formula" /></p>
|
|
</td>
|
|
</tr>
|
|
</table>
|
|
<p>I made this calculator to calculate the equation of each planes from three points, and then the angle between them:</p>
