We want to compare the current branch and another branch to find the changes since they diverged. For example, we create a new branch dev from branch master and add a few commits, the branch master also update after diverging. Read more…
Zhuanxu is the Emperor Huangdi’s grandson, he was smart and introverted in his childhood, the man helped Shaohao to manage Jiuli region when he was fifteen years old. Zhuanxu got superior political achievements at that moment, he was rewarded Read more…
The filter vtkWarpScalar can help us to move the point along point normal by the scalar amount times the scale factor. We can change the size of the original model with it as long as there are normals in data. Read more…
We can use VTK observer-command mechanism to listen to slider value changing event and override our responding method void Execute(vtkObject *caller, unsigned long, void*) to change target item’s size. It’s easy to implement with the subclass of vtkCommand and vtkSliderWidget. Read more…
AddInputConnection is a public interface provided by vtkAlgorithm. We can use it to combine multiple input sources to get a final 3D model with some special algorithm class. The following example has two VTK algorithm classes which show us the Read more…
vtkInteractorEventRecorder can be used to record VTK events in a single file and replay it by pass these events to vtkRenderWindowInteractor. Record The following code shows how to use it to save all interactive information into a file. We rotate Read more…
vtkAbstractWidget has its mechanism to handle interactive events. Here is a simple demo indicates the differences between the responses of widget and vtkInteractorStyleTrackballCamera. Example Code: int main() { vtkSmartPointer<vtkConeSource> cone = vtkSmartPointer<vtkConeSource>::New(); cone->Update(); vtkSmartPointer<vtkPolyDataMapper> coneMapper = vtkSmartPointer<vtkPolyDataMapper>::New(); coneMapper->SetInputData( cone->GetOutput() ); Read more…
Huangdi, the Yellow Emperor, is a Chinese ancestor and culture hero. It’s said that he has two possible last names, Gongsun or Ji, both have the style of Chinese dynasty Zhou. According to the record, the man could speak after Read more…
It’s a simple job for us to make bounding box visible in traditional VTK render window. We can SetCurrentRenderer for renderWindowInteractor->GetInteractorStyle() and press P to show it. #include <iostream> #include <vtkSmartPointer.h> #include <vtkSphereSource.h> #include <vtkActor.h> #include <vtkConeSource.h> #include <vtkRenderer.h> #include Read more…
