Conversion Examples

ThreeDConvertOptions supports conversion between 3D formats. The following examples demonstrate common conversions.

FBX to OBJ

Convert an Autodesk FBX model to Wavefront OBJ format:

using GroupDocs.Conversion;
using GroupDocs.Conversion.Options.Convert;
using GroupDocs.Conversion.FileTypes;

string sourceFile = "character-model.fbx";
string outputFile = "character-model.obj";

using (var converter = new Converter(sourceFile))
{
    var options = new ThreeDConvertOptions
    {
        Format = ThreeDFileType.Obj
    };
    converter.Convert(outputFile, options);
}

OBJ to FBX

Convert a Wavefront OBJ model to Autodesk FBX format:

using GroupDocs.Conversion;
using GroupDocs.Conversion.Options.Convert;
using GroupDocs.Conversion.FileTypes;

string sourceFile = "building-model.obj";
string outputFile = "building-model.fbx";

using (var converter = new Converter(sourceFile))
{
    var options = new ThreeDConvertOptions
    {
        Format = ThreeDFileType.Fbx
    };
    converter.Convert(outputFile, options);
}

FBX to GLTF

Convert an FBX model to GLTF (GL Transmission Format) for web and mobile:

using GroupDocs.Conversion;
using GroupDocs.Conversion.Options.Convert;
using GroupDocs.Conversion.FileTypes;

string sourceFile = "product-design.fbx";
string outputFile = "product-design.gltf";

using (var converter = new Converter(sourceFile))
{
    var options = new ThreeDConvertOptions
    {
        Format = ThreeDFileType.Gltf
    };
    converter.Convert(outputFile, options);
}

OBJ to 3DS

Convert an OBJ model to 3D Studio format:

using GroupDocs.Conversion;
using GroupDocs.Conversion.Options.Convert;
using GroupDocs.Conversion.FileTypes;

string sourceFile = "terrain-model.obj";
string outputFile = "terrain-model.3ds";

using (var converter = new Converter(sourceFile))
{
    var options = new ThreeDConvertOptions
    {
        Format = ThreeDFileType.ThreeDS
    };
    converter.Convert(outputFile, options);
}

FBX to U3D

Convert an FBX model to Universal 3D format for PDF embedding:

using GroupDocs.Conversion;
using GroupDocs.Conversion.Options.Convert;
using GroupDocs.Conversion.FileTypes;

string sourceFile = "mechanical-part.fbx";
string outputFile = "mechanical-part.u3d";

using (var converter = new Converter(sourceFile))
{
    var options = new ThreeDConvertOptions
    {
        Format = ThreeDFileType.U3d
    };
    converter.Convert(outputFile, options);
}

Format Support Notes

3D to 3D conversions are supported for most format combinations:

FBX → OBJ, GLTF, 3DS, U3D, DAE, DRC, AMF, PLY, RVM
OBJ → FBX, GLTF, 3DS, U3D, DAE, DRC, AMF, PLY, RVM
GLTF → FBX, OBJ, 3DS, U3D, DAE, DRC, AMF, PLY, RVM
3DS → FBX, OBJ, GLTF, U3D, DAE, DRC, AMF, PLY, RVM
All source 3D formats → Common target formats (FBX, OBJ, GLTF, etc.)

Note: To convert FROM 3D formats to PDF, use PdfConvertOptions.
