VRML / IV Coin 3D Interface Options
PDF3D Report Gen allows you to use the engine of your choice for the conversion for VRML or IV file types. The Coin3D tessellation engine is one such engine that is supported by PDF3D ReportGen. You can choose whether to use the tessellation engine or not using the option available under the Interface Settings tab.
To Use the Coin 3D Tessellation Engine for the Conversion:
- Click on the Interface Settings tab.
- Go to the Coin Interface Specific Options section and select the checkbox for Use Coin3D's tessellation engine. When you select this checkbox, Coin 3D's tessellation engine will be used for the conversion. The checkbox is not selected by default, you will have to manually select it in order to use it.
- If you decide not to use Coin 3D's tessellation engine for your conversion, just leave the checkbox blank. If not selected, the native PDF3D internal tessellation methods will be used, which is the preferred option in most cases.
- If you are processing VRML files from ArcScene, then it is recommended to Enable Geospatial Coordinates mode. This changes the transformation assumptions and menus, so that the default view is top, looking down at a plan landscape. Also layers are automatically recognised. On the PDF 3D View tab, the default views can also be selected to follow a geospatial oriented control system to be added to the PDF page.
- Define the other conversion settings and click on the Convert button to start the conversion or click on the Exit button to close PDF3D ReportGen without saving your current session. You can also save the session for conversion later.
- In the Optional treatments of VRML VRML97 CCW ordering and Normals field, select an alternative mode to improve conversion results. It is recommended that you use the first default setting. If you encounter shading issues, experiment with other modes. The options available are:
-
CCW 0: default mode, use file spec if possible - recommended option.
-
CCW 1: use file spec, but reverse the meaning
-
CCW 2: ignore file spec, always swap
-
CCW 3: ignore file spec, never swap
- In the Optional treatments of VRML97 solid parameter field, select an alternative mode to improve conversion results with respect to lighting and normal vector directions. The second option which is the default setting is recommended. If you encounter shading issues, experiment with other modes. The modes available are:
- SOLID 0: use file spec if possible
- SOLID 1: ignore file spec, never duplicate
- The LOD Processing Mode specifies the LOD level which will be used in the conversion progress where the originating model contains multiple resolution versions at various levels of detail. At highest LOD level, the model will have the most detail, generating the largest output detail. At lower LOD level, a simplified lower detail model will be used. Selecting Custom LOD Level enables the Specified LOD Level option for you to specify direcly the LOD level.
ANSYS FEA and ArcGIS Layers
- If you check the Scan Layer Nodes option, this enables scanning for internal layers (that may contain some specifications, like VRML comments) to create layers that may be controller from the layer menu system, with separate grouping nodes. This mode is especially helpfu if using VRML generated by ArcGIS ArcScene, where layer identifiers are stored as VRML comments.
- The Use ANSYS FEA Filter option invokes a special clean-up and reprocessing filter, designed for ANSYS FEA, CFX and similar VRML output of analysis results. This mode can dramatically improve efficiency of the conversion where contour bands are present, and for CFX the legend bar attributes are automatically identified.
- If using the ANSYS filter, the Ignore line sets option will only convert solid surface polygon portions of the scene.
- The Ignore last face set option is helpful where some ANSYS files add some extra axes or annotation objects into the 3D scene.
