I want to find the boundary of all projected points which are computed from the points on the 3D model. The red arrow in the following image represents the projected vector. I will project the original points on the 3D model to a plane.
cut a volume by a plane and display the cut section. The left renderer contains the original volume object, and the right renderer shows the cross section in the window.
I create two renderers that show the same 3D model. Make the camera in the right renderer linkage with the left one’s, that means we can get the same view in the right renderer when we modify the status of the camera of the left renderer.
Here is all information of implementations.
The parameter reference is frequently used CPlusPlus program, C++11 support copy construction and move construction for a new object, Use typeinfo or boost::typeindex to judge the variable’s data type information, The container std::array help us to manage a fixed size array.
Here are simple demos show how to use CGAL, the Computational Geometry Algorithms Library. I use cmake to manage these small projects.
Use vtkSurfaceReconstructionFilter to get mesh from the point coordinates.
I use the advancing front surface reconstruction way to get the mesh from point cloud information.
The function template std::bind generate a forwarding call wrapper of origin function, it returns a function object.
We can just call the wrapper to invoke the origin function.
The class template std::function is function wrapper, the instance of it can be copied and store.
I always get the error code 127 from my web application. I didn’t figure it out because it’s successful to run the program in the shell environment. The core logic in the calling function is like the following code snippet.
I want to create a 3D game by godot, here are some notes about it.
Add Music and add a test key and play our audio by it. Put Camera’s View To A Mesh’s Surface,
