The single element rule allows you to transform a simple point-based object into a 3D texture model.
The single element rule was designed for:
- Trees and bushes
- Lamp posts
- Fire hydrants
- Power poles
- Traffic signs
- Company logos
For single element rule creation, MAGNET Modeler supports:
Elevated points and circles can be used to create single element objects right away.
In case of zero elevation, all objects can also be translated to a reference surface.
A texture model is basically a model made of an image. MAGNET Modeler substitutes the point coordinate with a picture. Certain attributes control how the image behaves while the user navigates through the 3D scene. Use image files with a transparent background to get clean results.
Single element rule parameters
Click layer to access a list of all available layers in your current MAGNET Office project. Select one or multiple layers from the list where the rule should be applied to.
Click materials to access the Material Library of MAGNET Modeler. Select an existing material, or insert a new material.
Enter a description for the single element rule. This will change the name of the rule within the Modeler Rules window. In case you have several single element rules, this helps to easily identify them.
Click group to choose from a list of existing groups/subgroups, or manually enter your group structure. Use the forward slash character (/) to create additional subgroups, for example, Existing/Office/Parking lot.
Enter a value for width to control the width of the texture. If this attribute is empty, the texture is controlled by the material properties (defaultwidth).
Enter a value for height to control the height of the texture. If this attribute is empty, the texture is controlled by the material properties (defaultheight).
You can apply a randomness_size by applying a percentage between 1 and 100.
• Info text
Info text allows you to add additional information, such as material, quality requirements, manufacturer, etc. The info text information will be accessible in MAGNET Explorer via the Object Info tool.
• Info URL
Info URL allows you to add hyperlinks, such as a link to a manufacturer's homepage or a design document. The info URL link will be accessible in MAGNET Explorer via the Object Info tool.
Selecting bottom drapes the entities to the surface. The insertion point of the texture is at its center bottom. Selecting top uses the entities' elevation as the top of the object and stretches the texture down to the surface. This overrides both the width attribute and the defaultwidth. Selecting none uses the entities' elevation as the bottom of the object and assigns either the width attribute or the defaultwidth.
Position_offset allows a relative X, Y, or Z translation.
Selecting yes will automatically rotate the object to always face the viewer.
You can change the direction of the object by editing the rotation value. 0 equals the X-Z plane.
Z_rotating correlates with Z_rotation. Select yes to rotate the Z-axis.
Z_rotation will rotate the Z-axis. Setting this to 90 will result in the picture lying on the ground.
In case rotating is set to no, you can define a background_material, visible on the backside of the picture. If this is not set, the alpha channel of the picture is used. This means it looks the same from both sides.
You can use the alignment option to align the object perpendicular to the surface triangles (select surface) or leave it always vertical (select normal).
