Drawing Manipulator Class

Is there any function that can directly calculate the volume of an object?

If you are ok with the volume being calculated from the tessellated mesh and assuming the mesh is closed, its actually pretty straightforward to calculate with a bit of math. See here:

Hi,

you can’t directly open a PDF file in HOOPS Communicator. Instead HOOPS Communicator is able to extract and display the 3D content of a 3D PDF and display it in the viewer (simply run it through converter in the same way as any regular CAD file). If you need the ability to author and view PDF files with 3D content, you can also look at HOOPS Publish, which is our SDK more directly geared to the 3D PDF Format:

It means you can’t open the pdf directly.
If so, do I have to convert the file unconditionally to display the pdf in the viewer?

Excellent feature, and everyone’s communication is also exciting!

Are image files with the image extension .tif or .tiff supported?

If you are talking about the model conversion functionality of HOOPS Communicator we really don’t deal with images there, its really all about 3D model.
