  • [3D Math]Vectors

    Vectors are important to 3D world, especially Vector3. Math Basics Vectors are easy to understand compared to 3D rotations, but not all of them are straightforward. I will extract some important notes about 3D vectors. Cross Product derivative process We know: Then we can get: Finally: Interpolation linear interpolation Linear interpolation can not guarantee the…

  • [DevLog] Implement FABRIK in C++ for the Three Bone Chain IK Problem

    I completed a simple three bone chain IK demo using the FABRIK algorithm and raylib library. It’s simple enough and fast, and shows good results. Next time I want to add joint rotation limits to make it more exciting. 💪 Check out my Github repository for more details of IK problems. Error happened.
