Project Heightmap
The Project Heightmap operation projects a Heightmap onto a voxel grid at a right angle, similar to how an overhead projector works. This operation can repeat the pattern, allowing for efficient placement of heightmap data within your scene.
Steps to Project a Heightmap
- Select a Voxel Layer.
- Navigate to Voxel > Operations > Project Heightmap.
- Adjust the parameters in the Project Heightmap dialog.
- Click OK to apply.
Note
If voxels are selected, the Heightmap will only be projected onto those voxels.
Project Heightmap Dialog Parameters
The Project Heightmap dialog box includes the following parameters:
| Parameter | Description |
|---|---|
| Heightmap | Sets the Heightmap to be projected. |
| Rotate Heightmap | Rotates the Heightmap's pixel grid in 90° increments. |
| Flip Heightmap Horizontally | Flips the Heightmap's pixel grid horizontally. |
| Flip Heightmap Vertically | Flips the Heightmap's pixel grid vertically. |
| Projection Direction | Specifies the direction from which the Heightmap is projected. |
| Offset | Sets the offset of the projection relative to the chosen direction. |
| Repeat Horizontally | Toggles the horizontal pattern repeat of the Heightmap relative to the chosen direction. |
| Repeat Vertically | Toggles the vertical pattern repeat of the Heightmap relative to the chosen direction. |
| Pierce | Specifies whether the projection is applied to the first voxel it encounters or to all voxels beyond that point. |
| Hide Selection | Toggles highlighting of selected voxels. |
Note
Upon opening the dialog box, the Heightmap orientation is automatically adjusted to align with the closest direction facing the camera, and the position is set to ensure that the first Heightmap is placed on the voxel grid slice nearest to the camera.
Note
Any potential empty outer areas are automatically cropped from the Heightmap, ensuring that the default spacing between copies is zero, even if the Heightmap is not completely filled.
