Bryce: Underwater Scene

First of all, create your overall scene (don't worry about making it underwater yet):

  • Change your plane into something natural which you would find under water (i.e. sand)
  • Add a Terrain and erode it to look natural and weathered, then apply the proper texture
  • Add some items that you would find under water (i.e. anchor, fish, dolphin, etc.)
  • Add a water plane and move it up above your scene to create a water surface.
  • Try different skies until you find one that looks more realistic.

  • Next, add some haze and fog and adjust the colors accordingly.
  • Finally, add a spotlight and a filter to make light ripples.

Bryce: Streaming Light

Today we are going to do a project that adds realism to a piece of work, but requires some specific steps and setup.


Step 1: Disable Sunlight

Before beginning, go into the SKY LAB - Click Sky & Fog and then the "Rainbow" then click Disable Sunlight.
Step 2: Create a Block
Use the Resize tool to flatten the block into a wall shape.
Step 3: Reposition the Wall
Use the Reposition tool to move the wall back.
Step 4: Resize the Wall
Use the Resize tool to raise the height and expand the width of your wall.
Step 5: Create a Second Wall
Do a CTRL+C (to Copy) and then CTRL+V (to Paste)
Hold SHIFT and drag ROTATE to make a wall at a 90 degree angle
Step 6: Reposition the Second Wall
Use the Reposition tool to move it to the back.
Step 7: Create the Ceiling
CTRL+C (Copy) and CTRL+V (Paste) to create a new "Wall"
Use the Rotate tool (Z Axis) while holding SHIFT to make the new wall flat.


Step 8: Move the Ceiling Up
Raise the ceiling up using the Reposition tools.
Step 9: Resize the Ceiling
You want to have a ceiling large enough that you don't see light hitting the floor in your room.  Use the Resize tools (Front X and Z Axis) to make the ceiling larger.  Render the scene to make sure you have it covered.  If everything is correct, the rendered scene will be very dark.
Step 10: Create a Window-Shaped Block
Create a block and use the Resize tools to make it "window-shaped".
Use the Resize tool to drag out the Back Z Axis so that it easily goes through the back wall.  This shape will be used to cut a hole in the wall.
Step 11: Make the Block Negative
With the block selected, click on the A (Attributes) button.
Set the shape as "Negative" and deselect "Transfer Material of Negative Boolean"
Step 12: Make the Wall Positive
Click the A (Attributes)
Select the Positive bullet
Click the check mark.
Step 13: Make the Window Cutout
Select the block (the negative object).
Hold SHIFT and click the wall (the positive object)
Click the G (Group) button.
You should see a cutout shape in your wall.
Step 14: Render Your Scene
If you render your scene now, you should see a window shape.
Step 15: Begin Bars for Windows
While I personally don't LIKE bars on windows, adding them to this project allows the light streaming through the window to be broken up a little bit more.  It adds some interest to the final render.
Step 16: Finish the Bar
Use the cube in the center of the Resize tool to shrink your cylinder down to the thickness of a bar for the window.
Then stretch the shape out by grabbing the Y axis in the Resize tool to create the final bar shape.
Step 17: Copy the Finished Bar
Do a CTRL+C (Copy) and a CTRL+V (Paste) to make a copy of the bar.  Then use the arrows on the Reposition tool to drag the bar over.  Continue doing this until you have a series of bars.
Step 18: Group, Copy, & Rotate Bars
Next, hold SHIFT and select all of the bars.
Click G (Group) then CTRL+C (Copy) then CTRL+V (Paste).
Use the Rotate band while holding SHIFT to cross the bars.
Step 19: Reposition the Bars Into the Windows
Use the Reposition tool to move the bars back and into the window opening.
Do a Render to check positioning.
Step 20: Add a Spotlight
Create a new "Square Spotlight" (pyramid shaped).
Use the Resize tool (Y axis) and shorten the light about half way.
Step 21: Reposition the Spotlight
Use the Rotate tool and the Reposition tool to move the spotlight to the outside of the wall facing in through the window.  Note the shadow cast on the floor in the example.

Step 22: Adjust Spotlight Properties
(see image)


Finally, you can add some textures, additional items or even change the color of the light to get a fairly realistic scene.

Bryce: Cave or Tunnel Scene

Use your Boolean Difference technique to create a cave or tunnel scene.  You may need some sort of lighting to make it work.

In this example [right] I added a water plane and some ships, but I also added some fire and a light on the wall of the cave.

You might also have some luck adding haze and fog, or even adjusting the colors in the sky.  You can also experiment with adding external models.

Bryce: A Winter / Snowman Scene

Today I would like you to create a scene in Bryce set in Winter and featuring a snowman and/or a snow globe.
  • Change the texture of the Plane (it starts out as a flat gray)
  • Adjust the sky / change the texture
  • Add some objects (trees, rocks, snow, or whatever)
When finished, make sure to:
  1. Save your document (FILE > SAVE AS > whatever.BR7)
  2. FULLY render your scene
  3. Save your image (FILE > SAVE IMAGE AS > whatever.JPG)
  4. Upload your project to your portfolio.
Be creative and have fun!

Bryce: Importing External Models

As we learn object modeling in Rhino [which we will begin after Winter Break] we will be saving models to be used in other programs (like Bryce).  Fortunately there are also web sites which sell and/or give away external models which you can use to build your 3D projects.  For example, let's say you are trying to create a medieval scene with a knight on a horse, but you don't know how to "build" a horse.  You can download a pre-built horse and place it in your scene.

So where can you get 3D models?  Well, there are many in your L: Drive already.  You can browse through those models [most don't have good descriptions] and experiment a bit.

There are also many websites where you can download models:

Bryce: Boolean Difference

Today we will be learning how to create a "Boolean Difference" in Bryce -- basically meaning you cut one shape out of another shape.  The image below features a "cave" that was created by cutting a "symmetrical lattice" (looks like a mountain on top of an upside down mountain) out of a regular "terrain" (a mountain).  You can cut a block out of a sphere... a cone out of a pyramid, or whatever other shapes you might need. 

To begin this process:
  • Place the two shapes together intersecting one another (touching)
  • Select the shape you want to use as a "cutting tool" and click the "A" (Attributes) tool.
  • Select the "Negative" bullet and un-check the "Transfer Materials of Negative Boolean" option.
  • Click the "check mark" to okay the change.
  • Select the shape you want to cut IN to (the shape you want to keep).
  • Click the "A" (Attributes) button.
  • Select the "Positive" bullet mark and click the check mark to okay the change.
Next you have to "Group" the objects to be joined/cut:
  • Select the 1st object (i.e. the "negative" piece)
  • Hold SHIFT and select the 2nd object (i.e. the "positive" piece)
  • If it looks like you have other objects selected, deselect and try again.  You may have to rotate the scene a bit to make clicking easier.
  • With both pieces selected, click the "G" (Group) tool.
Now you should be able to "Render" your scence and view the cut out shape.

Bryce: Rounded Shapes: Bowls, Plates, etc.

We have a substitute teacher today, but I am still on campus.  I expect students to treat my substitute with respect and courtesy.

Today we will use the Terrain tool and a large, soft brush to create a rounded shape (i.e. a bowl).  Similarly you can use the "round edges" button to round existing Terrain shapes.

As with many of our projects in Bryce, we will be using a Terrain to build a shape:
  • Create a new Terrain object.
  • Click the E to Edit the Terrain.
  • Click the New button (or drop the elevation to black and paint over the whole Terrain).
  • Move the elevation all the way up (white).
  • Choose a soft-edged brush -- the largest available -- and center your brush on the screen (See Figure 1).
  • Click a few times.  You will notice a rounded shape in your preview window (See Figure 2).
  • Open the Brush Behavior window (Figure 3 #1)
  • Drag the bottom elevation slider (Figure 3 #2) up slightly [until the background turns red].
  • Click the Check Mark to accept changes to your new "rounded terrain"
  • Use your EDIT tools to rotate, resize, and reposition your new object.
  • Add a texture and use the object in a scene.
