Import and Render a 3-D Mesh with Fibers
Contents
Description
- This example reads the nodal parameters and element connectivity of a rabbit ventricular mesh and renders the elements, surfaces and fibers.
- The nodal coordinates and element connectivities are read from tab-delimited spreadsheets.
The steps below are saved in a script that can be found in the examples directory on your Continuity client .../continuity/pcty/examples/mesh07/renderFibers.py.py which can be executed automatically with File→Read→Python script
Start Continuity
- Launch the Continuity Client
On the About Continuity startup screen
leave the mesh checkbox checked under Use Modules:
Click OK
Set up coordinate system and basis functions
Select rectangular cartesian in the Global Coordinates: pop-up menu
Click OK to submit Coordinate Form
Choose Hermite Basis Function→3D→Cubic-Cubic-Cubic
Click Add Cubic-Cubic-Cubic
- Verify that the list of basis functions now contains:
- Cubic-Cubic-Cubic Hermite 3*3*3
- Cubic-Cubic Hermite 3*3
Click OK to submit Basis Form
Read nodal parameters and elements
Click Import/Export/Graph button to open Continuity Table Manager
Continuity Table Manager→File→Open...
Select tab-delimited nodes file (nodes.xls)
- You should now have nodes numbered 1-100
Click OK to submit Node Form
Click Import/Export button to open Continuity Table Manager
Continuity Table Manager→File→Open...
Select tab-delimited elements file (elems.xls)
- You should now have 48 elements
Click OK to submit Element Form
Calculate and render mesh
Click on nodes1 in the list on the left
Click on the Properties tab
For Size, enter 0.1 and hit Enter
Close the Open Mesh Controls form
- The mesh should look similar to the image below.
Click the lines radio button
Click Render to display mesh wireframe
- The mesh should now look similar to the image below.
Click the surfaces radio button
Click Render to display mesh surfaces
- The mesh should now look similar to the image below.
Mesh→Edit→Material Coordinates...
Click on the OK Button
Click OK to render fiber vectors
- You can change the size of the fiber vectors from View→Show Open Mesh→material axes3→Properties tab→Size
- The mesh should now look similar to these last screenshots, viewed from different angles.
