Re: Plane tool

Seems like I do indeed... So, can I still make it work on my Mac? I tried it on windows and it works great. I aligned the before and after treatment models based only on the posterior teeth and now I need to measure the amount of movement occurred on the front teeth. I can use a linear measurement t...

Plane tool

Hello, I have tried to use a Plane tool in Compass but my cursor and the circle do not correspond. There is about 3 inch distance between them. When I try to put the plane it puts it where the cursor is and not where the circle is. Aren't they suppose to correspond? Also, when I switch off 'auto rot...

Re: Aligning clouds by picking points

Hi Daniel, A. when I try to align (ICP) the segmented 'before' piece to the after model it often aligns it way wrong. I was able to play with it to overlay the segment as close to the 'after' position as possible and it sometimes does register it but it is kind of hit or miss. Do you have any tips o...

Re: Aligning clouds by picking points

Hi Daniel, please tell me where I am going wrong with this: A. - After I import my “Before” model of teeth in STL file, I sample points on a mesh to create a point cloud - Then I select points on I tooth I want to compare with the ‘Point picking tool’ (I am not sure how many I need to select but I w...

Re: Aligning clouds by picking points

Hi Daniel, I am still struggling to understand why every time I pick 3 points, it draws a rectangle through my points and it gives me a 4x4 matrix. It might be a silly question and I am sorry for it but I have no engineering or math degree and I tried to search online but all the talks about matrice...

Re: Aligning clouds by picking points

Hi, Daniel! I've tried that method and I like it much better than just measuring by picking points. I think your method is more accurate. Now, when I pick my points, it draws a rectangle no matter if I choose to pick three or four points. The matrix is 4x4, the 4th raw is 1. So, I assume I don't eve...

Re: Aligning clouds by picking points

Hi Daniel, thank you so much, your comment helped me to figure it out. Now, is there a way to align 2 point clouds by registering them automatically with point sampling instead of manually picking the points if I want just the posterior teeth to register and not the anterior ones. And what would be ...

Aligning clouds by picking points

Hello, I am very new to this program. I am in orthodontic residency and doing my master's research using this program on before and after tooth movement. I have 2 scans of teeth I have to align. I need to align only posterior teeth as only anterior teeth were moved with brackets. I watched tutorial ...
