FEM Mesh Analysis & Visualization in Model Module (refers below picture :-)) in other words, for example. each mesh, i want to calculate mesh volume and display different color corresponding to the volume. [image]

Does “Information” section shows the correct volume? You can color each mesh using a solid color (Display/Visibility/Color) or you can use scalars to color different parts of a model with different colors.

Does “Information” section shows the correct volume? ==> yes^^ You can color each mesh using a solid color (Display/Visibility/Color) ==> all of the mesh was drawn by same color ^^; i want to color each mesh with different color. each mesh, i want to calculate mesh volume and display differen…

You can assign a color to each mesh cell or point by assigning a scalar array to them and then configuring coloring in Models module’s Scalars section.

Scalar Array? for example? It means only editing Scalar Section in Model module can differentiate color each mesh or point?

Normally you assign scalar values to points or cells of your mesh when generate the mesh (e.g., you can have a scalar attribute to specify material or a physical quantity). How did you generate the mesh?

How did you generate the mesh? ==>Tetzen(Segment Mesher) on segmented surface of Brain Volume^^. I described in detail. plz refer below texts Normally you assign scalar values to points or cells of your mesh when generate the mesh (e.g., you can have a scalar attribute to specify material or a phy…

You need to use Cleaver to generate multi-material meshes. Tetgen could probably generate multi-material meshes too, but since it seemed quite complicated to set it up, and Tetgen had some stability issues, and comes with restrictive (GPL-type or commercial) license, we did not spend much time with…

Thank you so much, i am now reading cleaver mesh rendering process

I found source code inqMRMLModelDisplayNodeWidget.cxx.
in this source code. i can calcuate and set the color on each mesh from the input of Value in Model Display Widget UI ex. Threshold(Scalors section)
