curves: pushout curve points#
Sample points along curves in the input curvesBundle. When a range of these points falls within the bounding sphere / box of the prims within the collisionBundle, this node attempts to push those subsections of points outside the bounding volume in some reasonable way. This node outputs two bundles: a pointsBundle that contains one prim per polyline containing the displaced points of that polyline, and a curvesBundle that contains curve prims fit to those displaced points.
Installation#
To use this Node, you must enable omni.genproc.core in the Extension Manager.
Inputs#
Name |
Type |
Description |
Default |
|---|---|---|---|
Transform Bundle (curvesBundle) |
|
Bundle containing curves data |
|
Samples per Segment (samplesPerSegment) |
|
Number of points in each curve segment’s tessellation |
20 |
Transform Bundle (collisionBundle) |
|
Input meshes. The bounding spheres / boxes of each of these meshes will be used as the pushout volumes. |
|
Collision Proxy (collisionProxy) |
|
0 = Sphere, 1 = Axis-Oriented Box |
0 |
Push Out Horizontally (pushoutHorizontally) |
|
If true, pushout will not modify any particle’s vertical position (as defined by the specified up vector) |
False |
Up Axis Source (upAxisSource) |
|
0 = Use Scene Up, 1 = Use Node UpAxis |
0 |
Up Axis (upAxis) |
|
Up axis to be used when ‘Node UpAxis’ is specified as the up axis source. |
[0, 1, 0] |
Number of Segments (numberOfSegments) |
|
Number of segments per curve for each output curve. If this value is not positive, the number of segments in the corresponding input curve will be used. |
0 |
