Houdini 20.5 Nodes Geometry nodes

HeightField File geometry node

Imports a 2D image map from a file or compositing node into a height field or mask.

Since 16.0

Tip

To write a heightfield and/or mask to an image file, use HeightField Output.

Parameters

Source

Choose, wether you want to import an external image file or use the output of a compositing network.

COP Network

The path to the compositing network to use to generate the image data, when Use COP is on.

File

The path to the image file to import.

Reload File

Click to reload the image data from the disk file.

Channel

Selects which data channel to use as the value for the height field/mask.

Type

Whether to import the image data into a height layer or mask layer. For consistency with the Heightfield node, this node creates both layers but leaves the other layer set to 0.

Animated

If turned off, the file or compositing network will always be evaluated on frame 1. If turned on, the specified frame is used. Turn off the checkbox to avoid time dependency.

Size

Size Method

How to choose the size of the new volumes.

Size of Largest Axis

Make the longest side of the image the size specified in the Size parameter, and set the size of the other side proportionally.

Grid Spacing

Create a voxel for each pixel in the image, with spacing controlled by the Grid spacing parameter.

Size

The size in meters of the longest side of the image, when Size method is “size of largest axis”.

Grid Spacing

Distance between grid points, when Size method is “grid spacing”.

Uniform Scale

Scales the size of the volumes.

Height

Height Scale

Scales the height values from the image.

Clamp Minimum

Turn on the checkbox to clamp values to be at least this value.

Clamp Maximum

Turn on the checkbox to clamp values to be at most this value.

Position

Orientation

The initial axis alignment of the 2D volume in world space. The default is ZX, aligned with the “ground” plane.

Sampling

Where the center of voxels should lie, with respect to the given size. When Height Field Convert converts to polygons, these are the location of the points generated.

Center

Position on the center of the volumes in world space.

Rotate

When importing a mask, rotates the image data in the grid space. When importing a height field, rotates the volumes in world space.
