   Vector image export from Direct3D scene
  Is there any way to output 3D scene as vector graphics image file, such as a 3D CAD file, or SVG or EMF? Any third party libraries for accomplishing that? Any render target classes accepting privitive vertex data (also with textures) as source data? Currently we have only found a way to store it into various bitmap file formats.   
  Rendered images are, by definition, bitmaps.Usually the geometry to be rendered is in 3D vector representation before rendering. You could easily project this data to 2D vectors and export it. Most CAD formats support 3D vectors directly too.As for textures - if you need a 2D projection of a scene, you have to project the textures too. Note that SVG, EMF and such formats do not support true 3D texturing at all. CAD formats rarely support meaningful texture coordinates, apart from linear projection.
