Resizing Objects
When you create an object, it appears at a default size. Once you place it in your scene, you may need to resize it to make it proportional to the other objects in your scene.
There are three ways of resizing objects in Bryce:
- using the Resize tool, in the Edit palette, to resize an object along different axes
- using the 3D Transformation dialog which lets you enter precise values to resize objects
- using the control points on the object's bounding box to interactively resize the object
Objects are measured in Bryce units. When you resize an object, you're increasing or decreasing its size based on unity size. When you resize an object to 150%, you're sizing it to 150% of unity. Refer to "Bryce Units" for more.
Using the Resize tool
The Resize tool lets you resize a selected object along any axis. Objects are resized from their origin point.
The Resize tool has seven different states. As you move the pointer over the tool each state becomes active.
The Resize tool has seven states. As you move your cursor over the tool each state becomes active.
The different states let you resize the object along different axes. Resizing along the Y axis increases/decreases the object's height. Resizing along the X axis increases/decreases the object's width. Using the Z axis for resizing increases/decreases the object's depth.
To resize an object along a specific axis:
1 Make sure the Edit palette is visible. If it's not, click the Edit text button at the top of the Working window.
2 Move the cursor over the Resize tool.
3 When the state you want to use becomes active, drag to resize the object.
For example, if you're using Resize Y Up, drag to the right to increase the object's height in the Y axis. The more you drag, the taller the object becomes.
Hold down Shift to constrain the resize increments to 50% intervals when increasing the size of the object.
To resize an object in all directions:
1 Make sure the Edit palette is visible. If it's not, click the Edit text button at the top of the Working window.
2 Click the center of the Resize tool and drag right to increase the size of the object, or left to decrease it.
To resize an object from two directions along a single axis:
1 Make sure the Edit palette is visible. If it's not, click the Edit text button at the top of the Working window.
2 Move the cursor over the Resize tool.
3 When the state you want to use becomes active, hold down Option/Alt and drag in the direction you want to resize the object.
For example, if you're using Resize Y Up, when you hold down Option/Alt as you drag, the object becomes longer both up and down along the Y axis.
Objects can be resized using any of the three spatial definitions (World, Object or Camera). The definition you choose depends on the effect you wish to create.
To choose a spatial option for resizing:
1 Make sure the Edit palette is visible. If it's not, click the Edit button at the top of the Bryce window.
2 Click the triangle icon next to the Resize tool and choose an option from the menu.
3 Object Space resizes your selection relative to itself (see "Object Space").
World Space resizes your selection in absolute world coordinates (see "World Space").
Camera Space resizes your selection relative to the camera (see "Camera Space").
When you set Object, World, or Camera Space for the Resize tool, it is also the option set for the other two transformation tools. However, spatial options are global for the transformation tools only. The option you select in the Edit palette does not affect the 3D Transformations dialog.
Flipping Objects
Flipping is not the same as rotating an object 180°. Flipping mirrors an object along an axis instead of rotating it.
This example shows an object that has been rotated 180° and the same object flipped on its X axis.
To flip an object:
1 Make sure the Edit palette is visible. If it's not, click the Edit button at the top of the Bryce window.
2 Click the triangle icon next to the Resize tool and choose a flip option from the menu:
Flip X inverts your object's dimensions along the X axis.
Flip Y inverts your object's dimensions along the Y axis.
Flip Z inverts your object's dimensions along the Z axis.
To undo resize operations:
1 Make sure the Edit palette is visible. If it's not, click the Edit button at the top of the Bryce window.
3 Click the triangle icon next to the Resize tool and choose Unscale from the menu.
Numerical Resizing
Sometimes you will need more precise control over the size of your object. The 3D Transformations dialog lets you enter specific resize values for a selected object.
All transformations you enter in this dialog are performed in World Space regardless of the spatial option you chose for the Resize tool.
Resize values are expressed as a percentage of the current size of the selected object. You cannot enter negative numbers in this dialog.
To resize an object numerically:
1 Make sure the Edit palette is visible. If it's not, click the Edit button at the top of the Bryce window.
3 Click the triangle icon below the Resize tool and choose 3D Transformations from the menu. The 3D Transformations dialog appears.
4 Enter a percentage in one or all of the axis fields.
The percentage determines the new size of the object based on its original size. For example, to double the object's size in all directions, enter 200 in the X, Y, and Z fields. To resize along a single axis, enter values in only one axis field.
Since you are dealing with World Space transformations in this dialog, if you resize an object along only one or two axes you may unintentionally skew the object's shape.
To resize the object without skewing it, use the numeric entry fields in the Object Attributes dialog. Using this dialog can resize the object based on its original position, with no unintentional skewing. Refer to "Definition Coordinates" for more.Interactive Resizing
While you can resize objects using the Resize tool or the 3D Transformation dialog, there are resize controls on the object's bounding box that let you resize objects directly in the Working window. You may find this a much more intuitive way of transforming your objects.
When you select an object, a bounding box appears surrounding your selection. At each corner of the box, and at the center of each face, is a control point.
As your cursor passes over the corner control points, it changes to a generic Resize cursor. As it passes over the control points on the faces, it changes to an X, Y or Z. This indicates the axis along which you can resize the object by clicking and dragging at that point.
To resize an object along a single axis interactively:
2 Drag one of the control points at the center of a bounding box face.
As you pass your cursor over the face, the cursor changes to an X, Y or Z to indicate the axis you're resizing along.
To enlarge or shrink an object interactively:
2 Drag one of the control points on the corners of the bounding box.
Drag right to enlarge it, or left to shrink the object.
To resize an object from the bottom center:
2 Click the Y face control point and hold down the mouse button, then press Command/Ctrl+Option/Alt and drag the point.
The object resizes in all directions from the bottom center of the object. This transformation may be useful if the object is on the ground and you want it to remain there.
Using the Keyboard
You can also use the keyboard keys to resize objects:
Press * to double a selected object's size.
Press / to halve a selected object's size.
Press = to return the object to unity size and snap it to the Grid.
