The Transforms rollout is part of the Scatter parameters.
Random Translation
Moves the instances From the given distance To the given distance on the corresponding axis. See the Random Translation Example below.
Step Size – Specifies the random step size.
Example: Random Translation
This example shows how instances are moving along the corresponding axis. The scene for this example is set in inches.
X = 0-0; Y = 0-0; Z = 0-0
X = 0-25; Y = 0-0; Z = 0-0
X = 0-100; Y = 0-100; Z = 0-0
X = 50-100; Y = 50-100; Z = 0-0
X = 50-100; Y = 50-100; Z = 0-25
X = 50-100; Y = 50-100; Z = 0-100
X = 50-100; Y = 50-100; Z = 50-100
X = 0-100; Y = 0-100; Z = 0-0; StepSize = 0
X = 0-100; Y = 0-100; Z = 0-0; StepSize = 50
Random Rotation
Rotates the instances From the given degrees up To the given degrees continuously. See the Random Rotation Example below.
Step Size – Specifies the random step size.
Normal Alignment – When a value, different than 0 is entered, the instances are aligned according to the world up axis. This is useful when the host object is curved and the scattered objects need to remain vertical, not follow the curve of the surface. Positive values mean that the instances are aligned to the +Z axis (vertical up) and negative values mean that the instances are aligned to the -Z axis (vertical down). See the Normal Alignment Example below.
Preserve Rotation – Preserves the original rotation of the objects. This option is always enabled in V-Ray for Rhino. See the Preserve Rotation Example below.
Example: Random Rotation
This example shows how guest objects are rotated in a specific range. The scene for this example is set in inches.
Example: Normal Alignment
When a value, different than 0 is entered, the instances are aligned according to the world up axis. The scene for this example is set in inches.
X = 0-0; Y = 0-0; Z = 0-0
X = 0-90; Y = 0-0; Z = 0-0
X = 0-360; Y = 0-0; Z = 0-0
X = 0-360; Y = 0-360; Z = 0-0
X = 0-360; Y = 0-360; Z = 0-360
X = 0-0; Y = 0-0; Z = 0-360; Step Size = 0
X = 0-0; Y = 0-0; Z = 0-360; Step Size = 25
X = 0-0; Y = 0-0; Z = 0-360; Step Size = 125
X = 0-0; Y = 0-0; Z = 0-360; NormalAlignment = -0.75
X = 0-0; Y = 0-0; Z = 0-360; NormalAlignment = -0.5
X = 0-0; Y = 0-0; Z = 0-360; NormalAlignment = -0.25
X = 0-0; Y = 0-0; Z = 0-360; NormalAlignment = 0
X = 0-0; Y = 0-0; Z = 0-360; NormalAlignment = 0.5
Example: Preserve Rotation
The Preserve Rotation option determines which way the instances are rotated. The scene for this example is set in inches.
X = 0-0; Y = 0-0; Z = 0-0; Preserve Rotation = Off (Guest not rotated)
X = 0-0; Y = 0-0; Z = 0-0; Preserve Rotation = Off; Guest Rotated = 90
X = 0-0; Y = 0-0; Z = 0-0; Preserve Rotation = On; Guest Rotated = 90
Random Scale
Scales the instances From the given value To the given value continuously. When Uniform scale is enabled, the X axis values are applied on the whole Host object. See the Random Scale Examples below.
Step Size – Specifies the random step size.
Uniform Scaling – When enabled the X axis values are also used for the Y and Z axes.
Preserve Scaling – Preserves the original scaling of the objects. This option is always enabled in V-Ray for Rhino.
Example: Random Scale
This example shows how the Guest objects scale is modified. See the difference of the scaling with Uniform Scaling on and off. The scene for this example is set in inches.
X = 1-1; Uniform Scaling = On
X = 0-2; Uniform Scaling = On
X = 1-1; Y = 1-1; Z = 1-1.5; Uniform Scaling = Off
X = 0.75-0.75; Y = 0.75-0.75; Z = 1-1.5; Uniform Scaling = Off
X = 0-1.5; Uniform Scaling = On; Step Size = 0
X = 0-1.5; Uniform Scaling = On; Step Size = 0.75
X = 1-1; Uniform Scaling = On; Preserve Scaling = On (Guests Not Scaled)
X = 1-1; Uniform Scaling = On; Preserve Scaling = Off (Guests Scaled)
X = 1-1; Uniform Scaling = On; Preserve Scaling = On (Guests Scaled)
