Справка Houdini на русском Nodes Object nodes

Blend Sticky object node

Computes its transform by blending between the transforms of two or more sticky objects, allowing you to blend a position across a polygonal surface.

On this page

Overview

The Sticky object computes its transform from a UV position on a polygonal surface. Blend Sticky blends between two or more Sticky objects to get a new transform that still follows the surface. You can weight each input.

All inputs to this object must be Sticky objects, and all Sticky objects must be sticking to the same surface.

Parameters

Sticky Blend

Attribute

The attribute name of the texture to use for the polygonal parameterization.

Orient To Surface

Whether the local orientation of the point should be used. Uses the surface normal as the Z axis and the texture’s U axis as the Y axis.

Fetch World Transform

Uses the transform of the input Sticky geometry. If this is off, uses the parent transform of the Sticky Blend node.

Wrap in U/V

Wraps U and V values outside the U/V range. When this is off, the node ignores out of range U and V values.

U/V Range

The range of valid U/V values. Values outside this range will either wrap or be ignored, depending on the Wrap in U/V setting.

Assume UV Coordinates Unchanging

When this is on, the node saves time by not regenerating its cache of the target surface’s texture coordinates. Only turn this off if the target surface has animated geometry.

Clear UV Caches

Forces this node to regenerate its cache of the the target surface’s texture coordinates. This node is conservative about rebuilding the cache, so you may need to use this if you change the geometry of the target surface. For animated geometry, turn off the Assume UV Coordinates Unchanging.

Weights

The weight assigned to each input sticky object. Higher weights move the blended point closer to that sticky object.

Render

Display

Whether or not this object is displayed in the viewport and rendered. Turn on the checkbox to have Houdini use this parameter, then set the value to 0 to hide the object in the viewport and not render it, or 1 to show and render the object. If the checkbox is off, Houdini ignores the value.

Set Wireframe Color

Use the specified wireframe color

Wireframe Color

The display color of the object

Viewport Selecting Enabled

Object is capable of being picked in the viewport.

Select Script

Script to run when the object is picked in the viewport. See select scripts .

Cache Object Transform

Caches object transforms once Houdini calculates them. This is especially useful for objects whose world space position is expensive to calculate (such as Sticky objects), and objects at the end of long parenting chains (such as Bones). This option is turned on by default for Sticky and Bone objects.

See the OBJ Caching section of the Houdini Preferences window for how to control the size of the object transform cache.

Geometry Scale

Uniform scaling about the xyz axes.

Display

Whether to display only the icon, only the axis, or both.

Icon

Displays only the icon geometry.

Axis

Displays only the axis.

Icon and Axis

Displays both the icon and axis.

Control Type

Switches between the type of geometry to display.

Null

Displays null geometry (i.e. cross).

Circles

Displays circle primitives.

Box

Displays box primitive.

Planes

Displays plane primitives.

Null and Circles

Displays null and circle primitives.

Null and Box

Displays null and box primitives.

Null and Planes

Displays null and plane primitives.

Custom

If an input source is specified, this option will display the geometry of the input.

Orientation

Used in conjunction with circle or plane primitives. Determines which circles or planes to display.

All planes

Displays circle or plane primitives on the YZ, ZX and XY planes.

YZ plane

Displays a circle or plane primitive on the YZ plane.

ZX plane

Displays a circle or plane primitive on the ZX plane.

XY plane

Displays a circle or plane primitive on the XY plane.

YZ, ZX planes

Displays circle or plane primitives on the YZ and ZX planes.

YZ, XY planes

Displays circle or plane primitives on the YZ and XY planes.

ZX, XY planes

Displays circle or plane primitives on the ZX and XY planes.

Shaded Mode

Determines whether to display the primitives as shaded objects or as wireframe objects.

off

Displays primitives in wireframe mode.

on

Displays primitives in shaded mode.
