Uniform Cubic Spline To Smooth Segments Change input points and use the Cubic piecewise function introduced in Basic functions for B-Spline to create smooth curve. The left renderer shows polygon lines through original points, and the right one is the smooth curve generated by algorithm. Cardinal Spline To Smooth Segments Read more…

Bézier Curves Bézier curves are a type of parametric curve that is widely used in computer graphics, computer-aided design, and various other fields for creating smooth, elegant curves. They are named after the French engineer Pierre Bézier, who developed the mathematics behind these curves while working at Renault in the Read more…
ViewTransform stores three vectors in the first three rows and position information in the forth column. We can rotate camera around view up direction [ Azimuth operation ] and horizontal line (sideway) [ Elevation operation ] easily. The relative implementation details in VTK:
Books introduction page: Book content update: Add A Short Adventure About Pengjiamu In Xinjiang, Thailand Sleeping Beauty Cave Miracle Rescue Incident, and The Mystery of Shanghai’s Nine Dragon Pillars for Short Stories Book. Add a new e-book Traditional Chinese Medicine Health Tips. Here is a demo video shows how to Read more…
The interface vtkTransform::GetOrientation returns Euler angles to describes the orientation of a rigid body.The order of rotation axes in this process is Z, X, Y, but the solving sequence in the interface code is reversed.The implementation details about the interface are here. (from VTK8.2.0) We can write a test program to use Euler angles Read more…
We modified the web app images viewer to show the chosen image in real time. An new label at the left-top corner will shows the name of chosen image. Demo video (please pay attentation to the left-top corner) Related post:
Here are our files in project: Add a simple C function in lib.c: Get wasm without glue js file Download the wasm file and use the interface in html Result:
Here are some folders which contain json files.These json files have a version value, just look like the following image. We will increase this number by 10 for every json file in current folders recursively.Install command line tool jq to modify json file easily.Ubuntu: sudo apt-get install jqWindows: just download exe on the Read more…
