Houdini 20.0 Nodes Geometry nodes

Labs Pathfinding Global (Beta) 1.0 geometry node

This node creates paths between points of interest on a given terrain based on cost and avoidance attributes.

On this page
Since 19.5

This node takes points and their connections as input as well as a corresponding terrain, and generates the paths between them based on cost and avoidance attributes from the input terrain.

Parameters

Pathfinding

Point Cloud

Source

The source of the point cloud that is going to be used for the generation of the paths.

Existing Grid Points

Uses the points derived from the terrain mesh combined with the primitive centroid points.

Scattered Points

Scatters points in the terrain mesh.

Scattered Points

Generate

The method of generating the points to scatter to the surface of the terrain mesh.

Total Count

Generates an exact number of points to scatter to the surface of the terrain mesh.

By Density

Generates the number of points to scatter to the surface of the terrain mesh based on a density value.

Number of Points

The exact number of points to scatter to the surface of the terrain mesh.

Density

Value indicating the density of points to generate.

Relax Iterations

The iteration by which the points are pushed away from eah other.

Noise

Noise Amplitude

Introduces noise to the position of the points to break the uniformity and sharp corners of the paths that are going to form.

Path Cost Calculation

End Points: #id: endpoints The name of the end points attribute.

Attribute Name

The name of the attribute to use as cost for the pathfinding

Attribute Weight

The weight of the attribute that contributes to the cost.

Avoidance

Enable Avoidance

Use of avoidance to the pathfinding.

Avoidance

The name of the avoidance attribute.

Output Attributes

Output Distance

Output the distance attribute.

Distance

The name of the distance attribute.

Visualization

Visualize Point Cloud

Visualize the point cloud as guide geometry.

Point Cloud Color

The color of the point cloud.

Visualize Terrain

Visualize the terrain mesh as guide geometry.

Terrain Color

The color of the terrain guide.
