Intermixing volume and mesh to create a special effect in FluoRender 2.34

Use the script "convert_mesh" to convert a multichannel volume data set to mesh objects. You can load the multichannel data set as a "Batch" sequence and run the script.

Mixing two types of neon colors for the same scan, colors by components and a linear gradient controlled by a ruler, have you tried the new features in FluoRender 2.34?

Depth attenuation can now be set to use the background color. Enable the setting under "Rendering" and you can create a fog effect.

Have you tried the "candy mode" in FluoRender? Here are the steps. 1. Select part of the volume using the brush or grow tool. 2. Convert the selection to a mesh object. 3. Lower the transparency of the mesh object. 4. Enable color map for the selection and set mode to radial. 5. Create a ruler tool to cover the selection.

Try the mesh brush in FluoRender for instant segmentation and mesh generation in 3D. Pre-release 2.34 has been available for Windows. I'm working on packaging for macos, which should be available soon.

Updated the UI for mesh conversion and added new tools to the workspace toolbar

The upcoming release of FluoRender significantly extends the possibilities of render modes, including some seemingly impossible modes previously. Here is an example of two channels of volume in MIP mode, with color map applied, alpha disabled, and intermixed in depth mode. Then, they are mixed with a mesh object with shadow effects, which is generated from paint selected regions from one volume channel. The restructuring of FluoRender's rendering pipelines provides the flexibility to implement these interesting features easily.

Mesh generation by grow selection is streamlined for an intuitive process in the upcoming FluoRender release.

I implemented the mesh simplification function. Now, streamlining volume data to mesh conversion is functional by volume selection -> mesh conversion -> simplification -> smoothing -> visualization/export.
