Loading a Model

You can use the Load Model command when you want to load a 3D model into the 3D Model window.

The file can be in several file formats and you can import files from other 3D systems as well.

Note: Starting from version O/18, all avatars load with sizes, final poses, accessories/add-ons that were predefined when creating the avatar. If you want to modify sizes, poses, etc. you have to do so using the Avatar Editor and then load the file again. For more information, see Avatar Editor.

Icon & Location

Toolbar: 3D

To Load a 3D Model:

Click on the Load Model icon in the 3D toolbar.

The Open dialog is displayed:
From the Files of Type drop-down list, select the type of file you are loading.

The following types are supported:

Model Files (*.mod), Cloth Files (*.clt), 3D Studio Max Files (*.3ds), VRML2.0 Files (*.wrl), AutoCAD Files (*.dxf), PLY Files (*.ply), Body Morph Files (*.mrp), Measure Files (*.ord), Biovision BVH Files (*.bvh), OBJ Files (*.obj).

.

If you are importing an OBJ file, click here

If you are importing a 3DM file, click here

Once you select a File Type, settings may appear on the right-hand side of the dialog. These settings are dynamic according to the type of file you are loading.
3DM is a Rhino file format.

The new functionality (Rhino parser) includes:
- Importing Rhino (.3dm) files into PDS.
- Exporting Rhino (.3dm) files from PDS as V4 Rhino model. (can be read by Rhino V4 or V5)
Limitations to note:
- No shaders are implemented for Rhino parser.
- Rhino parser import does not have tessellation ability. A Rhino model without render meshes cannot be imported to PDS. (This can occur, for example, if user never shades a viewport in Rhino or used "Save small" flag, when saving model in Rhino.)
To Import 3DM:
1. In the File of Type field, select 3dm Files (*.3dm) from the drop-down list.
2. Browse and select your file.
3. Depending on the way the file was exported, you may need to change the Import Settings.
4. Depending on the origin of the file, you may need to Flip the Normals of the imported model.
Window Snapshot
OBJ is a universally accepted open file format. Optitex users can import OBJ files exported from 3D Scanners such as TC2 and Human Solutions to name a few.

To Import OBJ:
1. In the Files of Type field, select Optitex OBJ Files (*.obj) from the drop-down list.
2. Browse and select your file.
3. Depending on the software from which the file was exported, you may need to change the Import Settings.
4. Depending on the origin of the file, you may need to Flip the Normals of the imported scan.

Setting	Description
Scale	Change the scale factor. This is used if the imported model is too big or small and it depends on the system it was generated from
Working Units	Set the working units in which the fields were exported.
Rotate Y (Degrees)	Rotate the model in the Y direction.
Flip Y And Z	Flips the Y and Z axis.
Position	Select to define a static distance or enter a defined direction and pivot point.
Merge With Scene	Merge the imported model to the scene.
More Options	Define advanced import settings
Position	Centered: Places the model in the center of the 3D environment Place on Floor: Places the model with the floor displayed Offset X,Y,Z: defines the x,y,z offset of the 3D model
Polygons
Tessellation Resolution	Set the tessellation resolution of a 3D file. This is used when importing files with high number of vertices that slows down the system tremendously. 'Restore Defaults' set the resolution to it's original value. This slider option is designed to meet the needs in which performance is more important than mesh quality and vice-versa. Its calculation will depend upon: Mesh edge length is maximum 1cm. Surface tolerance: In relation to the dimension of the surface, the tolerance will specify the maximum allowed distance between the original surface and the new mesh curvature. Normals tolerance: Specifies the maximum distortion angle from the original surface normals at points on a facet.

Select the model, and then click Open.
