Why Does The Canvas Id On HTML Page Have To Be `canvas` For VTK WebAssembly?
I got the following error information on the web page if I change the id of canvas to be ‘canvas1’. The function USDL2OpenGLRenderWindow::CreateAWindow is similar to vtkSDL2OpenGLRenderWindow::CreateAWindow. We can read VTK and SDL library source code and find these code snippets. File: video\emscripten\SDL_emscriptenvideo.c device->CreateSDLWindow = Emscripten_CreateWindow; static int Emscripten_CreateWindow(_THIS, SDL_Window Read more…

3D Model Editor – Find Non-manifold Edge And Points
In the mesh structure of 3D models, there is a kind of situation that can make many 3D algorithms useless or even break down. Because the default input model for many 3D algorithms is a manifold structure. But sometimes we get a data that is not manifold. The left side Read more…
