Houdini 22.0 Nodes Copernicus nodes

HeightField Project Copernicus node

Projects 3D geometry onto a heightfield.

On this page

This node projects 3D geometry onto a heightfield by rasterizing the geometry’s distance from the heightfield’s imaging plane.

This node uses the Rasterize Geometry COP internally and shares the same geometry restrictions. The geometry input must be polygons. This node does not work on packed geometry or volumes.

Tip

To create mountains, set Project to Maximum Height. Then, set Blend Mode to Maximum.

To create valleys, set Project to Minimum Height. Then, set Blend Mode to Minimum.

Parameters

Project

Specifies which height sample to rasterize.

Minimum Height

Rasterize the minimum height sample.

Maximum Height

Rasterize the maximum height sample.

Max Projection Height

The maximum absolute height that can be projected. The node will not project geometry that is outside of this range.

Mask

The amount of projected height to mix with the original height.

Blend Mode

Specifies how the projected height is mixed with the input height.

Blend

Replaces the input height with the projected height.

Add

Adds the projected height to the input height.

Multiply

Multiplies the input height by the projected height.

Maximum

Takes the maximum of the projected height and the input height.

Minimum

Takes the minimum of the projected height and the input height.

Output Projection Only

When enabled, outputs only the projected height values.

Inputs

height

The height layer to project geometry onto.

geometry

The geometry to project.

mask

An optional per-pixel mask amount that’s scaled by the Mask parameter.

Outputs

height

The resulting height layer with the projected height values blended in.

hitmask

The resulting mask layer containing a value of 1 where geometry was rasterized.
