Is there a way to convert an Adobe 3D-pdf file to WebGL? I searched the web but couldn't find a method. Adobe 3d pdf files have the disadvantage that they can only be viewed directly in the browser in Internet Explorer (and maybe on Safari -don't know), but if you use Firefox or Chrome, you need to download the file and open it in Acrobat. Moreover you need to activate it, sometimes adapt security settings... Whilst WebGL works directly in modern browsers. The export to 3d pdf is from Amira.
回答1:
It is in fact possible to convert 3D PDF to WebGL.
You've got multiple options:
- Content in 3D PDF is either u3d or prc. Use the respective library to read data and write to WebGL format.
- Get the designed 3D model if you have access to it and skipping 3D PDF, just convert that model to WebGL.
- Use Hoops, which is capable of this conversion.
