I can’t display vtkContourWidget object on web page by wasm file.The following code snippet is very simple, create a circle and show it, we can modify it by vtkContourWidget object.The example works in CPlusCPlus program.VTK version: 9.0.2. But it will Read more…
We will introduce the transformation equation for 3D Coordinate Value XYZ And 2D Texture Coordinate UVR. Try to represent the UVR value by x,y, and z. Here is derivation process. Read more…
In the following example, we will create a function to compute number’s factorial result.Let’s echo in the function to support fetch return value outside. Output:
If you have a few zip files in a folder, and the zip file had compressed some child zips, the following shell script can help you to extract them. The compressed information in our example look like: Shell script: #! Read more…
Rename Files’ Suffixes Recursively And Find Folders Find Folders To find all folders in the current path, I wrote a simple shell script file. It ignores invisible folder which path looks like ./.XXX. #! /usr/bin/bash dirs=() find . -type d Read more…
The post shows how to use VTK to display 3D model with shading.We need to make sure the version of VTK is equal to 9 or bigger than it.To avoid the faceted appearance, compute points’ normal to support to has Read more…
The post is related to The Example About vtkPolyDataNormals. If you want to use vtkPolyDataNormals to compute the normals of points, it’s better to set variable Splitting false. #include <vtkVersion.h> #include <vtkSmartPointer.h> #include <vtkSurfaceReconstructionFilter.h> #include <vtkProgrammableSource.h> #include <vtkContourFilter.h> #include <vtkReverseSense.h> Read more…
