Most modeling in Bryce requires boolean operation. This can be done with a combination of different Bryce primitives, a single one, or with imported objects like dxf or obj. The following shows how to do this. However, it shows the roughest form by using boolean to cut out portions of an objects center...it should be noted that this operation can be used to shape an object's edge as well. By placing a negative primitive (or imported object) at a positive object's edge, the edge can be carved to whatever shape is desired.
| First Create a
Cylinder. Select its attributes by clicking the "A" next to it. Then
make it a positive object by clicking "Positive".
|
Duplicate the
cylinder by going to "edit" then select "duplicate".
|
| Make this cylinder
slightly smaller in the x and z planes. [It may be necessary to make it larger in
the y plane so that it is slightly larger (taller) than the original.] Next make this object a negative by selecting "Negative".
|
Select both
cylinders by either dragging a marquee around them with the mouse or holding the
"Shift" key and clicking each one.
Select the "G" which groups the two cylinders. |
| The negative cuts
a hole in the positive cylinder. This results in a tube . |
You can create complex boolean objects by then selecting the
"A" for the tube object and making it a positive object by selecting positive. |
| Create another
cylinder and position it so that it intersects with the tube. Make the cylinder negative by selecting the "A" and selecting negative.
|
Next group the
negative cylinder with the positive tube by selecting both objects (shift click both or
marquee with mouse) then select the "G" which groups the two objects. This results in a hole cut in the tube.
|
Use operations like this to create any object you can imagine.
After you have completed reading the above, you should practice a little making basic boolean objects. After you feel you have a hang of it, you may want to visit the advanced boolean tutorial.
This is not meant to be an all inclusive instruction on every possible way to have made the final image or produce the desired results. Bryce offers zillions of wonderful ways to replicate, multireplicate, reposition, etc. in its powerful interface. Experiment!
