Voxel layer

The mathematical shape in the above screenshot is rendered with the voxel layer. The effect used is Voxel/VoxelGoursatSurface.

What can I do with the voxel layer?

With the voxel layer you can render voxel models.

How do I add a voxel layer?

Choose LAYER > Add layer > Add voxel layer... to add a new voxel layer.

The new voxel layer can be selected from the layers dropdown to make it the active layer.


The installer comes with shows demonstrating the possibilities of the voxel layer. Choose FILE > Open show... and select a show from the BluffTitler/Media/Shows/Voxel folder.

To quickly switch between your own shows and the ones that came with the installer, click on the Personal and App buttons in the upper right corner of the file dialog.

Medical visualisations

The voxel layer is mostly used to visualise medical datasets of CT and MRI scans.

This example shows a molar (tooth) converted from a DICOM file.

Voxel layer style 1

Not clipped

The voxel model is not clipped.

Front clipping plane

The position and rotation of the clipping plane can be set with the Position clipping plane property and Rotation clipping plane property.

Back clipping plane

Renders the other side of the clipping plane.

Clipping plane

This renders the clipping plane itself.

Voxel layer properties


The position of the voxel model.

1st slider: horizontal (x) position

2nd slider: vertical (y) position

3rd slider: depth (z) position

Press <F2> to render the coordinate system.


The rotation of the voxel model.

1st slider: heading

2nd slider: pitch

3rd slider: roll

Press <F2> to render the coordinate system.


The size of the voxel model.

1st slider: width (x)

2nd slider: height (y)

3rd slider: depth (z)

Tissue density

The range of visible tissue.

1st slider: minimum density
2nd slider: maximum density


The colour of the voxel model.

1st slider: red

2nd slider: green

3rd slider: blue

When you press <F3> and the mouse is inside the tool window, the standard Windows colour dialog is presented. When the mouse is outside the tool window, the colour of the current mouse position is copied: it's a colour picker!


The size of the specular highlights.

Set the specular colour with the Specular colour property.

Position clipping plane

The position of the clipping plane.

Rotation clipping plane

The rotation of the clipping plane.

1st slider: heading

2nd slider: pitch

3rd slider: roll

Press <F2> to render the coordinate system.

Voxel resolution

The number of slices used to render the voxel model.
