RotateUVW

Description

Rotates texture coordinate elements

Scripting Syntax

RotateUVW( InputObjs, TextureProjection, [X], [Y], [Z], [Delta], [AxesFilter], [Pivot], [PivotU], [PivotV], [PivotW], [AspectRatio] );

Parameters

Parameter Type Description
InputObjs String List of objects or components to translate.

Default Value: Selected elements

TextureProjection String Texture projection to modify.
X Double U rotation in degrees.

Default Value: 0.0

Y Double V rotation in degrees.

Default Value: 0.0

Z Double W rotation in degrees.

Default Value: 0.0

Delta siDeltaMode Specifies whether to rotate the object a relative or absolute amount

Default Value: siRelative

Possible Values:

Description:

siRelative Rotation is relative to existing rotation
siAbsolute Rotation specifies an absolute orientation
AxesFilter siUVWAxesFilter Determines which of the u,v,w arguments are valid

Default Value: siUVW

Possible Values:

Description:

siU Filter in U
siV Filter in V
siUV Filter in U & V
siW Filter in W
siUW Filter in U & W
siVW Filter in V & W
siUVW Filter in U & V & W
Pivot Boolean If true the specified pivot point is used for the rotation, otherwise the center of geometry of the sample points is used.

Default Value: False

PivotU Double The U coordinate of the pivot arround which the rotation will be made.

Default Value: 0.0

PivotV Double The V coordinate of the pivot arround which the rotation will be made.

Default Value: 0.0

PivotW Double The W coordinate of the pivot arround which the rotation will be made.

Default Value: 0.0

AspectRatio Double The aspect ratio (x resolution/y resolution) of the image for which the UVs are being used. If specified, the command performs a scaling to compensate for the aspect ratio.

Default Value: 1.0

Examples

VBScript Example

' This example creates grid and applies a texture on it. It then modifies a subset of its uvw coordinates

' by rotating them 45 degrees.
