We want to put points on the three-dimensional model sometimes, it’s better if these control points can be moved around the item and project generates a new interpolation line dynamically. VTK provides a tool for us to do it easily. Read more…
The article shows how to create a simple vtk render window project. We need cmake and the visualization toolkit installed. This example uses C plus plus programming language to create and show a cone in the 3D world. CMakeLists.txt cmake_minimum_required(VERSION Read more…
Independent Thread We want to run a single task in an independent thread in a convenient way in some scenarios. It is common in data process and UI interaction event, for example, we want to use QMovie object to play Read more…
Git Rebase git rebase [ []] git wiil go to another branch by command git checkout firstly and then apply the commits on it to area. We wiil start with the example showed in the last article Git Diff Different Read more…
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…
