Sometimes we need to change canvas for VTK WASM 3D window.Updating renderer window and renderer is neccessary if we don’t restart all data loading.The related post is Change Canvas For VTK WASM Project. I got the following error info on the web page if do vtkSDL2OpenGLRenderWindow::Render before m_RenderWindow = newWin; (update the old rendererWindow variable). Read more…

The post demonstrates the process of configuring the 3D window after switching from the original canvas to another. After clicking on the update button at the bottom-left position on the webpage, we will call Worker::ChangeRenderWindow to handle the scene. index.html: The interface in worker.cpp: The whole project had been uploaded Read more…
The project shows how to call JS function defined in web page by CPP code. Here is files tree for projThe images display the directory tree of the project. The main logic code about our question: worker.cpp index.html The whole project had been uploaded to GItHub: https://github.com/theArcticOcean/tutorials/tree/main/learnWebAssembly/CppWasm The build way Read more…
Here is a simple example about how to use VTK to listen for window resize event on web page. As we knew, we can build the VTK CPlusPlus project to wasm to run on browser. If we want to do something when browser change window size, we have to add Read more…
In the past two months, we have unfortunately experienced incidents where our server’s CPU usage became excessively high, resulting in site outages. After analyzing the backend data, we have implemented restrictions on the usage frequency of the tex-to-docx and png-to-svg tools, as follows: Regular users will only be able to Read more…
We have added a new feature to the 3D Model Editor. It can remove non-monifold edges and non-monifold points. The non-monifold edges and non-monifold points are introduced at https://www.weiy.city/2022/09/3d-model-editor-find-non-manifold-edge-and-points/. Let’s create a cube with non-monifold edges and non-monifold points by the following code. The model file had been uploaded to Read more…
We have added a new feature to the 3D Model Editor. It can reconstruct the cells with bad cell normals, and the updated cell normals now face outwards. This aligns with the principles of light reflection. Tool: https://www.weiy.city/functions/3D-Model-Editor/ Demo video: The red area indicates the cells with bad cell normals. Read more…
