Creating Infinite Planes
An infinite plane object extends in all directions to infinity. When you create a plane in Bryce it appears as a finite plane to make it easier to position, but when your scene is rendered the plane extends infinitely in all directions.
Though procedurally these three infinite planes are different, they are all considered to be Infinite Planes for the purpose of selecting with the Selection tools.
When you add a plane object it appears as a finite object in the Working window...
...but when you render the scene it extends to infinity.
Ground
Ground planes are created at ground level. By default, all new scenes open with an infinite ground plane.
To create a Ground plane:
Once the plane appears in your scene you can edit it like any other object.
The Ground plane is created with a gray color, as are all Bryce primitives. Once you begin assigning textures to objects, Ground objects (as well as all other primitive objects) will inherit the texture assigned to the previous object.
Water
Water planes are created just a bit higher than ground level. That way, if you have already created ground and terrains, you can easily place a water plane into your scene and immediately see the terrains peeking out from the water.
To create a Water plane:
Once the plane appears in your scene you can edit it like any other object. Refer to "Editing Object Attributes" for more on editing objects.
Water planes are created with a water texture randomly chosen from the Waters & Liquids Preset Materials Library. You can change this material by selecting a different preset or creating a new material.
To change the water plane's Preset Material:
1 Click the second Triangle icon at the top of the Bryce environment. The Preset Materials Library appears.
2 Choose a library and material, then click the OK icon.
Refer to "Using the Materials Presets Library" for more on the Preset Materials Library.
Cloud
Cloud planes are placed much higher in your scene, since they're generally the highest objects in your environment.
To create a Cloud plane:
Once the plane appears in your scene you can edit it like any other object.
Cloud planes are automatically assigned a randomly chosen texture from the Clouds & Fogs Preset Materials Library. You can change this material by selecting a different preset or creating a new material.
To change the Cloud plane's preset material:
1 Click the second Triangle icon at the top of the Bryce environment. The Preset Materials Library appears.
2 Choose a library and material, then click the OK icon.
Infinite Slabs
An infinite plane is a plane object that has no depth. An infinite slab is a plane object that has depth. The plane has no effect on objects above it or below it; an infinite slab can affect objects within it.
For example, anything you place within the slab's depth will be affected by the slab's volume color.
Slabs are usually used to create water. When you create a water slab, you create water with realistic volume. This means that if you sink an object into the water it will be affected by the colors or textures you assign to the slab's volume.
The realistic look of a water slab depends almost entirely on the material you assign to it. The Volume color plays an essential role in creating realistic water effects. Refer to "Volume Color" for more on Volume Color and materials.
To create an Infinite Slab:
1 Click the plane tool and choose the Volume option from the popup.
3 Click the A icon that appears next to its bounding box. The Object Attributes dialog appears.
4 Enter a depth value in the Size Y field and click the OK icon.
