Foliage produces various types of plant objects such tree species. Autodesk VIZ generates mesh representations to create fast, efficient, and good-looking plants.
You control height, density, pruning, seed, canopy display, and level of detail. The seed option controls creation of different representations of the same species. You can create millions of variations of the same species, so each object can be unique. With the viewport canopy mode option, you can control the amount of plant detail, reducing the number of vertices and faces Autodesk VIZ uses to display the plant.
-
Use the Spacing tool to place plants along a path.
-
Use vertex or face snapping (see Snaps Settings) to position plants on a surface.
To add plants to a scene:
-
Click the Favorite Plants rollout > Plant Library button to display the Configure Palette dialog.
-
Double-click the row for each plant you want to add or remove from the Palette and click OK.
-
On the Favorite Plants rollout, select a plant and drag it to a location in a viewport. Alternatively, select a plant in the rollout and then click in the viewport to place the plant.
-
On the Parameters rollout, click the New button to display different seed variations of the plant.
-
Adjust the remaining parameters to show elements of the plants, such as leaves, fruit, branches, and if you want, to view the plant in canopy mode.
This rollout lets you set the foliage object's name, color, and default material. For detailed information, see Object Name and Wireframe Color.
When Favorite Plants rollout > Automatic Materials is on, each plant is assigned its own default material. For more information, see Favorite Plants rollout, following.
The palette displays the plants currently loaded from the Plant Library. There are three ways to add a plant to the scene:
Automatic Materials—Assigns default materials for the plant. To modify these material assignments, use the Material Editor. Select the plant in the viewport, and click Main toolbar > Material Editor. Click the Get Material button to display the Material/Map Browser. Under Browse From, choose Selected. Then, from the list pane, double-click the material list item for the plant to display the materials in the Basic Parameters rollout of the Material Editor.
If you turn off Automatic Materials, Autodesk VIZ assigns no materials to the object, unless the Name And Color rollout > Default Material check box is on and a default material is assigned. This way you can specify a particular default material for all foliage objects. For more information, see Object Name and Wireframe Color.
When on, Automatic Materials overrides the Default Material settings.
Note: Even if Automatic Materials is off, Autodesk VIZ still assigns material IDs to the foliage objects, so that the object is ready for a multi/sub-object material.
Plant Library—Displays the Configure Palette dialog. Using this window, you can view information on the available plants including their names, whether they’re in the palette, their scientific names, types, descriptions, and the approximate number of faces per object. You can also add and remove plants from the palette, and clear the palette, which removes all plants from the palette.
Tip: To quickly add or remove a plant from the palette, double-click its row in the Configure Palette dialog. The Fav. (Favorite Plants) column entry switches between "no" and "yes." Click OK to accept the changes and exit the window.
Height—Controls the approximate height of the plant. Autodesk VIZ applies a random noise factor to the height of all of the plants. Therefore, the actual height of a plant, as measured in the viewports, won't necessarily match the setting given in the Height parameter.
Density—Controls the amount of leaves and flowers on the plant. A value of 1 displays a plant with all its leaves and flowers, .5 displays a plant with half its leaves and flowers, and 0 displays a plant with no leaves or flowers.
Pruning—Applies only to plants with branches. Removes branches that lie below an invisible plane parallel to the construction plane. A value of 0 prunes nothing, a value of .5 prunes the plant at a plane halfway up its height from the construction plane, and a value of 1 prunes everything possible from the plant. What Autodesk VIZ prunes from the plant depends on the type of plant. The trunk is never pruned.
New—Displays a random variation of the current plant. Autodesk VIZ displays the seed value in the numeric field next to the button.
Tip: Click the New button repeatedly until you find the variation you want. This is often easier than trying to adjust the tree using modifiers.
Seed—A value between 0 and 16,777,215 representing the possible variations of branch and leaf placement and shape and angle of the trunk of the current plant.
Generate Mapping Coords—Applies default mapping coordinates to the plant. Default=on.
Controls the display of leaves, fruit, flowers, trunk, branches, and roots of plants. Available options depend on the type of plant you select. For example, if a plant doesn’t have fruit, Autodesk VIZ disables that option. Turning off options reduces the number of vertices and faces displayed.
In Autodesk VIZ, the canopy of a plant is a shell covering the outermost parts of the plant, such as the leaves or the tips of the branches and trunk. The term derives from "forest canopy." Use reasonable parameters when you create many plants and want to optimize display performance.
Because this setting applies only to the plant's representation in the viewports, it has no effect on how Autodesk VIZ renders the plant. For information on how Autodesk VIZ renders the plant, see Level-of-Detail.
When Not Selected—Displays the plant in canopy mode when it’s not selected.
Always—Always displays the plant in canopy mode.
Never—Never displays the plant in canopy mode. Autodesk VIZ displays all the features of the plant.
Controls how Autodesk VIZ renders the plant. For information on how Autodesk VIZ displays the plant in the viewports, see Viewport Canopy Mode.
Low—Renders the plant canopy, providing the lowest level of detail.
Medium—Renders a reduced-face-count version of the plant. How Autodesk VIZ reduces the face count varies from plant to plant, but it usually involves removing smaller elements of the plant or reducing the number of faces in the branches and trunk.
High—Renders all the faces of the plant, providing the highest level of detail.
Tip: Set the parameters before creating multiple plants. This can avoid slowing down the display, and might reduce editing you have to do on the plants.
