How to rotate a 3D meshgrid around a specific point (not center point)

3 次查看(过去 30 天)
Hi Everyone,
I want to rotate a 3D image around a specific point (not in center point). Below is a code that I used imrotate3, and it was rotated around center point
DoseSimulated = imrotate3(DoseSimulated,XrotSAG,[1,0,0],'cubic','crop');
DoseSimulated = imrotate3(DoseSimulated,YrotCORO,[0,1,0],'cubic','crop');
DoseSimulated = imrotate3(DoseSimulated,ZrotTRAN,[0,0,1],'cubic','crop');
where DoseSimulated is 3D dose image (it is a medical image), and XrotSAG, YrotCORO, ZrotTRAN are corresponded rotation degree about X axis, Y axis, Z axis.
Can anyone know how can I solve it.
Thanks for your reading thru.

First translate the image https://www.mathworks.com/help/releases/R2020a/images/ref/imtranslate.html to the center point and then apply the rotation.
