Title: How to make pore space transparent or invisible in GeoDict visualization?
Post by: Shunsuke Takai on May 26, 2026, 09:56:29 AM

Hello,

I imported CT TIFF images of a fibrous catalyst layer into GeoDict and successfully reconstructed the structure.

However, I have a problem with the visualization.
The pore space is displayed as a white phase, so the internal fiber structure cannot be seen clearly.

I would like to know if it is possible to:

・make the pore space transparent,
・hide the pore phase completely,
・or directly visualize only the fiber structure inside the reconstructed model.

Could you please tell me how to change these visualization settings in GeoDict?

I attached an image showing the current problem.

Thank you very much for your help.

Hello Shunsuke,

You can change the appearance of any material (including the pore space) directly from the Color & Visibility panel that is located on the right‑hand side of the GeoDict user interface. Below is a quick walk‑through of the most common options you mentioned.

Hide the Pore Material Completely

Open the Color & Visibility panel (second entry in the sidebar).
Find the row that corresponds to your pore phase. In your case it is ID00 Pore.
Uncheck the Visible checkbox next to that row. The pore volume will no longer be shown, so you will see only the fibers.

Tip: If you still see a gray background after doing this, you're probably looking at the CT images volume field that GeoDict keeps after segmentation. In the View Controls → Volume Field section, uncheck the Volume Field box to turn it off.

Make the Pore Material Transparent

In the View Controls panel, expand the Structure tab.
Choose Transparency Mode → either Volume (entire materials) or Surface (only the material boundaries).
Click the Edit button below.
In the dialog, set the transparency slider for the Pore phase to the desired value (0% = fully transparent, 100% = fully opaque). Click Apply.

Additional Visualization Options

Shadows: Go to Camera (in View Controls) → enable Shadows.
There are also other lighting options under the same tab.
Background: You can change the Background Color in the Color & Visibility panel.
