1. Model Setup
The initial process for the creation of a road visualisation is to have a suitable survey model and design model. For the demonstration of the process in this document the models below are used as examples.   Survey Model - SURV Design Model - OPT 4

These models should be associated with the relevant style and feature sets. The style and feature sets can be set by selecting Model Defaults in the Tools menu. Figure 1.1 shows the dialog boxes for the style and feature sets linked to each model. Figure 1.2 & 1.3 shows the models when displayed using these style and feature sets.

2. Model Masking & Boundary Creation
When the models have been set up a mask file may be required to mask out strings that are not required from the models. In this example the strings below require exclusion from the Design model.     Volume string – VOL1 Master string – MC41 Boundary string – BOP4 Fence strings – BOP4

Create a mask file by selecting Selection Mask Tables in the Tools menu. Figure 2.1 shows the dialog box setup for the selection mask table.

Figure 2.1

When the strings have been added hit Save As and save the file to the ProjectStyles folder. In this example the file was saved as Design Mask.msk, no strings were required to be masked for the Survey model. String masking will be individual to each project and mask files may be required for both the Design and Survey models. A boundary string is required for the Design model as part of the process for creating a composite model. A boundary string can be created by selecting Create a Boundary around a Model in the Modify>Edit Strings menu. The Design Mask.msk needs to be selected for the Design model. Once the Design model has been selected and the mask file selected hit Next to create the boundary. In

the following dialog box use BOUNDARY as the Model Name and B000 as the String Name. Hit Finish to save the boundary. Figure 2.2 shows the dialog box setups for the creation of boundary.

Figure 2.2

A visual check of the boundary string should be carried out as the boundary may require editing after creation. This guide assumes the user is familiar with editing points on strings. The completed boundary string for the Design model is shown in Figure 2.3 below.

3. Create Composite Model
The first step to creating a composite model is to display both the Survey model and Design model as shown in Figure 3.1.

Figure 3.1

To begin creating a composite model select Create Composite Model form the Modify>Edit Models menu. The initial dialog box asks to Select Outside Model, the outside model is the survey model. In this dialog box select the Survey model and hit Next. Figure 3.2 shows the set up for this dialog box.

Figure 3.2

The next dialog box asks to Select Inside Model, the inside model is the design model. In this dialog box select the Design model, for the boundary select BOUNDARY as the Model Name and B000 as the String Name and for the masking select Design Mask.msk. Figures 3.3 and 3.4 show the set up for these dialog boxes.

4. Create Composite Triangulation
To create a triangulation of the composite model select Triangulation from a String Model from the Analysis>Triangle menu. Select COMPOSITE MODEL as the Model to Triangulate and COMPOSITE TRIANGULATION as the Model to Store Triangulation. In the Trimming Details tab select the radio button for Trimming Method A. Hit OK to create the triangulation. Figure 4.1 shows set up for the dialog box and Figure 4.2 shows the created triangulation model.

5. Triangulation Seeding
5.1 Setting up the Automatic Seeding
The next stage is to seed the triangulation, seeding is the process of adding groups to a triangulation model i.e. Road, Shoulder, Grass etc. This process allows for the creation of rendered images and videos once the triangulation has been associated with the relevant style and feature set. Display both the COMPOSITE MODEL and the COMPOSITE TRIANGULATION as this will make it easier to determine the locations for the different groups. To start seeding the triangulation you need to select Automatic Seeding from the Analysis>Triangle menu. This brings up the dialog box in Figure 5.1. Select COMPOSITE TRIANGULATION as the Triangulation Model and COMPOSITE MODEL as the Model Name. Hit Next to continue, this will bring up a warning to assign the default style set, hit OK to continue. Figure 5.1.1 shows these dialog boxes.

Figure 5.1.1

This will apply a default group to the triangulation as shown in Figure 5.1.2 below.

The first process is to set the entire triangulation to the GRAS group, this will the largest group in the triangulation. Select GRAS from the drop down menu, and select Highlight as this will highlight the triangles before they are seeded. This will make it easier to determine the triangulation that will be seeded. To seed the triangulation with the GRAS group select Feature Select and click on the triangulation. You will have to select separate triangulation areas to set the entire triangulation to GRAS. Once complete the triangulation should look as in Figure 5.1.4, the GRAS shows up as green.

5.2 Seeding the Design Model
The Design model needs to be seeded for the various groups. For this example 3 seeding groups are used, ROAD, SHDR and KERB. Select ROAD from the drop down menu. Select the area between the design carriageway strings to seed the road of the Design model. Figure 5.2.1 shows the ROAD seeding as grey.

Figure 5.2.1

Select SHDR from the drop down menu. Select the areas between the shoulder strings to seed the shoulders of the Design model. Figure 5.2.2 shows the SHDR seeding as orange.

Figure 5.2.2

Select KERB from the drop down menu. Select the area between the design carriageway strings and the edge of shoulder strings to seed the kerbs of the Design model. Figure 5.2.3 shows the KERB seeding as white.

Figure 5.2.3

A visual check of the design model should be carried out to ensure that it has been fully seeded. If triangulation areas have been missed then these will have to be selected manually using the Paint Brush.

5.3 Seeding the Survey Model
The Survey model needs to be seeded for the various groups. For this example 2 seeding groups are used, ROAD and RIVR. Select RIVR from the drop down menu. Select the area between the river strings to seed the river of the Survey model. Figure 5.3.1 shows the RIVR seeding as blue.

Figure 5.3.1

As some of the river triangles were not automatically seeded theses have to be manually selected using the Paint Brush. Figure 5.3.2 shows the completed RIVR seeding.

6. Visualisation Setup
Once the seeding is completed the triangulation should look similar to Figure 6.1 below. The COMPOSITE MODEL can be unloaded from the view.

Figure 6.1

The initial stage in setting up the visualisation is to change the feature and style set to MFW Grouped Triangles with materials for the COMPOSITE TRIANGULATION model. This associates materials with the various seeding groups in the triangulation. Figure 6.2 shows the dialog box for this.

Figure 6.2

To display a basic render of the seeded triangulation select a new view from the View Toggles and use the Rotate View button to give a 3D view of the triangulation model. Figure 6.3 shows the 3D view. Note that the MFW Grouped Triangles with materials now displays the triangulation as a wireframe.

7. Fly Through Video Creation
The initial stage to setting up a fly through is to create a path for the fly though to follow. For this example a path will be created following the centreline of the road but set at a height of 1.2m above the road. This will create a fly through from the perspective of a vehicle driving along it. Create a new model called FLY THROUGH and assign style and feature set MFW Detail Design. Figure 7.1 shows the set up for the dialog boxes.

Figure 7.1

To create a new string above the centreline select Design A String: Horizontal Offset from the Design>Design a String menu. Use LC00 as the new string name, set the Horizontal Offset to 0 and set the Constant Vertical Offset to 1.2. Figure 7.2 shows the set up for the dialog boxes.

Figure 7.2

To create the fly through select Fly Through from the Utilities>Render menu. This will bring up the Fly Through Producer dialog box as shown in Figure 7.3.

Set Standard Lens to Normal, Target Position to Floating (this follows tangentially along the string), View to 2, Render Setup to Untitled, Render Mode to From View, Speed to 5, Resolution to 640 x 400 and Frames to 500. Figure 7.4 shows the dialog box setup.

Figure 7.4

From the select Define Path from the Tools menu of the Fly Through Producer. Select the start of LC00 string and the end of the LC00 string when prompted. Once the path has been defined the FLY THROUGH model can be unloaded as it is not required for the video rendering. Select Record from the tools Tools menu of the Fly Through Producer and select Windows Avi as shown in figure 7.5. This will create a basic video of the fly through.
