VTK

The post shows a way to calculate unsigned distance Between Two 3D Models. The models can’t have too low resolution because the result that vtkDistancePolyDataFilter computes will not be accurate. #include <vtkActor.h> #include <vtkCleanPolyData.h> #include <vtkDistancePolyDataFilter.h> #include <vtkNamedColors.h> #include <vtkNew.h> #include <vtkPointData.h> #include <vtkPolyDataMapper.h> #include <vtkPolyDataReader.h> #include <vtkProperty.h> #include <vtkRenderWindow.h> Read more…

I found a new way to make interpolation spline curve smoother. Let’s explore it based on the previous post, VTK – Make Interpolation Spline Curve Smoother. Take every point and its neighbor points on the curve, generate two vectors and . Make the second point B to be the midpoint Read more…

I have two old posts about draw display bounding box, VTK: Show Display Bounds After Project Points and VTK: Show Display Bounds. But they didn’t give me a statisfy result.In this post, I find feature edges of the mesh firstly, convert the world points to display points by vtkViewport object. Read more…

Here is a 3D object lock from Create Lock By Blender. We can use vtkPolyDataSilhouette to extract a subset of a polygonal mesh edges to generate an outline (silhouette). #include <iostream> #include <vector> #include <iostream> #include <vtkPolyData.h> #include <vtkProperty.h> #include <vtkPolyDataMapper.h> #include <vtkActor.h> #include <vtkPlane.h> #include <vtkRenderer.h> #include <vtkRenderWindow.h> #include Read more…

The post shows a way to scale image which is displayed by vtkActor2D object. We used vtkImageResize that performs sinc interpolation on images to change their sizes. #include <vtkCamera.h> #include <vtkImageActor.h> #include <vtkImageCanvasSource2D.h> #include <vtkImageData.h> #include <vtkImageMapper3D.h> #include <vtkImageReader2.h> #include <vtkImageReader2Factory.h> #include <vtkImageResize.h> #include <vtkImageSincInterpolator.h> #include <vtkInteractorStyleImage.h> #include <vtkNamedColors.h> #include Read more…
