Is "Viewfile" the same as the "datafile" generated in the .view directory? The "datafile" that I am looking at for the 3D case is different from the format of the "Viewfile" given in the documentation. I have therefore documented the format of the "datafile" that I am seeing (information from 'src/graph/view3D/write3d.c' and from looking at the actual file generated).
I assume this file is needed for communication between C code and x-window viewer.
Viewfile Data Format:
1=view3Dtype, 2=viewgraphtype, 3= view2Dtype, 4=view tube type
title
window boundaries: X, Y, width height
0=no display, 1=display | scale factors X and Y | change in X and Y increments | centre for X and Y axes
Datafile Example
The datafile is always written to 'directoryname.VIEW' directory regardless of what other filetypes may have been selected, this file is used for internal purposes but it may be useful for other things. The information from the following table is taken from 'src/graph/view3D/write3d.c'. It is a text file and is roughly in 3 parts:
- header with general information about dimensions, view, light, etc..
- list of points containing 4 float values (x,y,z coordinates and c (I assume colour?))
- list of indices of the points which specify components, made up of lists, made up of points.
In more detail the entries are as follows:
| line in file | data: where there are more than one value per line they are separated by spaces | |||||||
|---|---|---|---|---|---|---|---|---|
| 1 | typeOf3D | |||||||
| 2 | xmin | xmax | ymin | ymax | zmin | zmax | ||

example of a datafile Since the file is very long I have removed multiple lines where you see..<snip>..:
