Hello all. A very simple question, the answer to which may help unlock
OpenDX for me. I am trying to create a glyph, and as a test case I want to
make a cube. I have set up a DX file cube.dx containing the geometry:
# The following example describes an irregular grid. Note that the values
# of the "positions" component and "connections" component are irregular,
# and so must be enumerated. It is a cube.
#
# The irregular positions, which are 8 three-dimensional points.
object 1 class array type float rank 1 shape 3 items 8 data follows
-0.05 -0.05 0.1
0.05 -0.05 0.1
0.05 0.05 0.1
-0.05 0.05 0.1
-0.05 -0.05 0.0
0.05 -0.05 0.0
0.05 0.05 0.0
-0.05 0.05 0.0
# The irregular connections, which are 6 quads
object 2 class array type int rank 1 shape 4 items 6 data follows
1 0 2 3
1 2 5 6
2 3 6 7
3 0 7 4
0 1 4 5
5 6 4 7
attribute "element type" string "quads"
attribute "ref" string "positions"
# The data, which is in a one-to-one correspondence with the positions
object 3 class array type float rank 0 items 8 data follows
2 2 2 2 3
3 3 3
attribute "dep" string "positions"
# the field, with three components: "positions", "connections", and
# "data"
object "irregular positions irregular connections" class field
component "positions" value 1
component "connections" value 2
component "data" value 3
end
In a simple .net file I use Import -> ShowConnections -> Image to satisfy
myself that this is a cube, but I can't figure out the next step, how to
make the surfaces visible. The sample AutoGlyph3DScalar.net uses Construct
-> Connect -> Shade, but I want to set up the geometry in a .dx file.
Please provide guidance.
Thanks
Gib
