Use CTRL+D to start copying the sand512 tile, using the Attributes window to move each new tile by 400 in the X or Y direction.  As the tiles get farther away from the viewer, switch to the lower grid sizes.  If you've ever tiled a floor, this will seem very familiar.

The Oasis

To make the oasis, select sand2048a and go into the terrain editor. Press Invert and then Blob Maker to make a new hill in the middle of the terrain. Press Invert again and sand2048a is restored to its original shape except for a pit in its middle.  The terrain canvas with the pit added is shown below.

Exit the Terrain Editor, select all 4 of the 2048 grid terrains, group them together, and assign them to Family 2. Create a 2D Disk with the values shown in Table 2 and apply a water texture to it. Assign this disk to Family 6 and call it Water.

The Grass

The grass around the oasis was created in Plant Studio, a standalone program that generates 3D models of a wide variety of plants.  27 different models of grass, each with 0 degrees of rotation, were generated in Plant Studio and exported as 3DS files.  These models were imported into Bryce as family 5 and kept ungrouped.  After selecting family 5, the Attributes window was opened (by clicking the little "A" in the box next to the model) and the grass was rotated 90 degrees on the X axis to correct the orientation after importing.  After accepting these values by clicking the check mark, the Multi-Replicate window was opened by pressing ALT+SHIFT+D.  The quantity was set to 5 with a rotation of 3 degrees on the Y axis. This resulted in a total quantity of 162 plants whose orientations vary over a range of 15 degrees.

Building the Pyramids

The original pyramids took years to make at a cost of untold human suffering. Unless you’re a tyrant with thousands of people who obey your every whim, you will probably be better off building them in Bryce. Just create three pyramids using the values given in Table 2.  The texture applied was "Arizona", from the Planes & Terrains materials library.

The values for the pyramids were found after a lot of digging on the Internet.  Their size was scaled up to match the trees.  The average height of a tree object in the Attributes menu was 64.  This is easily twice the height of the real tree in feet, so I doubled the dimensions of the pyramids to keep everything to scale.  For this picture, one unit in Bryce = 6 inches.  The viewpoint in the picture is from the southwest of the pyramids, looking to the northeast, about 1600 feet from the nearest pyramid (Menkaure).  In case you're interested, the names of the three pyramids are, from largest to smallest, Khufu or Cheops, Khaefre or Chephren, and Menkaure.

Adding the Trees

Now that you have a suitable landscape built up, it's time to add the trees.  Select Tree1 and move it to a suitable location using the Attributes window.  Copy Tree1 using CTRL+D, assign the new tree to Family 21, and call it Tree2.  Use the same process to create Trees 3, 4, 5, and 6.  You can use the tree positions given in Table 2 unless you see something you think would look better.  If the trees look too similar, you can change the value of the randomness slider for each tree in the Tree Lab.  You can also change the rotation on the Y axis so the tree presents its best side to the viewer.

The final image was rendered twice - once with normal shadows and once with Soft Shadows enabled in the Sun and Moon section of the Sky Lab under the Sky & Fog Palette.  The resulting Render Reports are shown below with normal shadows on the left and soft shadows on the right.

Rendering was done on a PC with an 850 MHz Athalon processor and 768 MB of RAM.  The file size was just under 200 MB with 1048 objects and 52442883 polygons.
