Original file formats
- *.x3d
- *.obj wavefront
Comments
- to download a model (x3d, obj and textures) visit 3d+map - open 3d scene then click the download button.
- textures are *.png files are shared between x3d and obj
- x3d - textures are listed inside
- obj - textures are listed in an extra (material) file - *.mtl
- most of the time textures will be located in the same dir
- if downloading a model manually - do not forget textures (and a corresponding *.mtl for *.obj)
Programs
- MeshLab
- CloudCompare
- Blender
Convert *.x3d to other 3D formats
MeshLab
- File > Export Mesh As... supports a few formats: *.3ds, *.ply, *.stl, *.obj, *.dxf, *.dae, *.xyz, etc.
- *.x3d to *.obj:
- there will be 2 files generated: *.obj and *.obj.mtl - the latter contains a list of texture files which should be kept around as well
- *.x3d to *.obj:
Blender
- Supports some x3d files but not all
View
MeshLab
- Open *.x3d
Notes:
- Lights off
- Couldn't adjust proper camera settings
Blender
- Convert to *.obj in MeshLab
- File > Import > Wavefront (.obj)
- Switch viewport shading to texture (in Default view it's located next to the Object mode)
- Also, set Shading Multitexture shadeless
CloudCompare
- Convert to *.obj in MeshLab
- Drag and drop *.obj into the CloudCompare window
- Options > Display parameters > Colors and Materials > set all lights to white
- Options > Camera parameters > set Camera/Eye center and fov
