So is there a quick way to convert a .dae file (COLLADA) to a .osg (OpenSceneGraph) file?
Do you have the collada loader plugin and the standard command line osg utils? If so,
osgconv FILE.dae FILE.osg
from a command line will do it.
If you don't have the COLLADA plugin, you can use sketchup with Ryan Pavlik's osg exporter: https://github.com/rpavlik/sketchupToOSG
As a side note, this means it is super-simple to get anything from Google's 3D Warehouse into osg native formats, which means tons of great models.
From what i remember the Blender 2.49 was able to import Collada files and export OpenSceneGraph files.
You can give it a tray and download this version of Blender plus the exporter for OSG.

There is also an .osg exporter for 3DS Max: http://osgmaxexp.wiki.sourceforge.net
You can import your .dae there and then use the exporter to create an .osg.

Is there any existing python package that can be used to handle METEOR RADAR data sets which are in .hwd file format?
I want to work on atmoshpereic science project on tide analysis in the MLT region using python.So, the source of the data is METEOR RADAR which stores data in .hwd file format(height width depth).
I tried searching the internet for specific packages that could help me file handle .hwd files but ended up finding no packages or libraries that are currently active.
Could you please help me?
Thank you.
I figured this out!
There is no need for external packages to work on hwd files in python.
hwd files stand for Horizontal Wind Data files. So, METEOR radar stores data in hwd file format, which can be treated as a normal text(.txt) file for file handling in python.
I have been searching the web for hours trying to find something that might help me convert a file that was saved in the ppt file type to the pptx file type using python. I found "python-pptx" and was planning on using it to save the files, however this was not possible due to the continuous error:
Package not found at 'FileName.ppt'
I discovered another post (Convert ppt file to pptx in Python) which did not help me at all. I assume it is because my python version might be too high. (3.9) After reading up on getting the win32com.client to work and installing multiple pip and pip3 commands, it is still not working. If anyone could assist me with this manner I would be very thankful. My Current Code:
from pptx import *
prs = Presentation("FileName.ppt")
prs.save("FileName.pptx")
You can use Aspose.Slides for .NET and Python.NET package for converting PPT to PPTX as shown below:
import clr
clr.AddReference('Aspose.Slides')
from Aspose.Slides import Presentation
from Aspose.Slides.Export import SaveFormat
# Instantiate a Presentation object that represents a PPT file
presentation = Presentation("presentation.ppt")
# Save the presentation as PPTX
presentation.Save("presentation.pptx", SaveFormat.Pptx)
Our web applications use our libraries and you can see conversion results here.
I work at Aspose.
I doubt python-pptx can parse a .ppt file. (It's a completely different file format.) You're better off automating PowerPoint itself - somehow - to read one and write the other.
The "somehow" depends on the platform you're running on - and the automation capabilities available to you.
I am trying to use EECodes in python to get various weather information, such as temperature, humidity, etc out of grib2 files. I am using the GFS files. I would like to be able to extract the data as (lat,lon,alt,$data_point), and as a 2d array for each altitude.
I have tried the example programs located here: https://confluence.ecmwf.int/display/ECC/grib_iterator_bitmap
I can't figure out what I am looking in the output of that program. When I load the messages using their keys, it is not obvious how to make a grid. When I load the grid, the data doesn't have labels I understand.
#craeft have a look to https://github.com/ecmwf/cfgrib. cfgrib is the new standard for python and grib file handling. It is easy to install and easy to access files. Please install the latest version because it supports GFS files.
I am unable to export rigs with .obj file in blender.I know that object can be exported with rigs by .fbx and other formats but the format I require is .obj. Please tell me if there is a way to export .obj file with rigs armature in blender.
In all versions of blender this is not possible with obj files. They are mesh and texture files only. OBJ is a very old format. Try using DAE files. They are beautiful magic. If all else fails use fbx.
I've managed to compile GDCM with VTK and I have a particular application I would like to use, which is the "gdcm2vtk.exe".
Now, how's the syntax for converting a stack of imags into a ".vti" file? so far I have this:
gdcm2vtk Input_Directory file.vti
Now, when I run somthing like this:
gdcm2vtk "C:/dicom/dicom directory" output.vti I get an error:
could not find no reader to handle file: "C:/dicom/dicom directory"
Is there anything I'm missing there?
gdcm2vtk does not handle a directory as input as specified in the documentation.
You may want to convert your DICOM Series into a single DICOM Instance using gdcmimg
As of GDCM 2.6 gdcm2vtk is now able to take as input a directory. Pay attention to sort the file according to the well known Image Orientation (Patient) & Image Position (Patient) strategy instead of relying on the filenames ordering to reconstruct your VTK (*.vti) file:
$ gdcm2vtk --ipp-sort input_dir output.vti
