Marlijn,

Thanks for your nice response.

 I used your instructions and did open 3D viewer, but when I selected surface...smooth, I got a "Runtime Error.9 .out of range". I checked my data, and there are no polygons the number of which is outside my total dataset, so it may be the way I designed my polygons.

According to the Morphologika manual, you can make the polygons clockwise or anticlockwise, the direction determining whether the polygon faces out or in. Thus, for example, if a right sided polygon on the face starting at the midline were 1 2 4, on the left it might be 1 2 5, with the 1 & 2 along the midsagittal line. Am I wrong? If I am getting landmarks from a skull, all having a starting point on the midline(sagittal), should they ALL be one direction?

Thanks,

Don

Dear Dr. Lewis,

Regarding your second question on polygons:

Within morphologika, upload your data, run the GPA and then activate 
the 3D viewer by clicking on this window. A new option will show up in 
the top toolbar, 'Rendering'. Clicking on this will show you three 
option to view your data: points, wireframe or surface (=polygons).

If you cannot choose the option surface within this menu, it probably 
means there is something wrong with how you defined the polygons. Make 
sure the polygons are all described either in clock-wise or all 
described in anti-clockwise direction. Input of polygons is similar to 
that of wireframes, numbers with spaces in between:

[polygons]
1 2 3
3 4 5
6 9 8
etc

Also, make sure you do not include any landmark numbers in your 
polygons that you do not include in your final morphologika analysis. 
Deselecting certain landmarks within the Morphologika program will not 
automatically also delete the polygons (or wireframe lines) that 
involve the deleted landmarks.

Good luck!

All best,

Marlijn

All,

Two vexing questions:

1. I have a group of 27 landmarks for the base of a given skull land a 
group of 40 landmarks for the top. How do I combine these in 
Morphologika to render the entire skull? Currently they are in 
separate Notepad text files. There ARE four points common to each 
group, but the specimen was turned over for measurement purposes.

2.POLYGONS: I have used the command line [polygons] and denoted the 
three landmarks to be linked, but cannot figure out how to get 
anything but points on the display. No wireframe, no polygon, just 
points.

Thanks for any help.

Don
