Highlights: Hello and welcome. In this post, we will see examples and how we can rotate 3D objects. We will see how we can rotate a 3D cube around each axis, the \(x, y, z\) axes. Definition of the cube Now, we will do an example in Python by creating a 3D object which will consist of points with 3 dimensions. This 3D object will be a cube and we will rotate it around the…

Highlights: Hello and welcome. Today we will continue our series of posts about 3D face modeling. In this post, we are going to talk about parametric face model tracking and reconstruction. In the previous posts, we talked about how to create a parametric face model. Now, let’s talk about what we can do once a face model is created. More specifically, how can we reconstruct a face from an image into a 3D form (3D…

Highlights: Hello and welcome. In this post, we shall describe a modeling technique for 3D textured faces. By converting a set of 3D face models’ shapes and textures into a vector space representation, we will be able to create a morphable face model. By creating linear combinations of face models, new faces and facial expressions can be generated. So, let us begin this journey! 3D Database of Faces (Cyberware TM) In order to create 3D…

Highlights: Hello and welcome to our new post. Here we are going to talk about Principal Component Analysis (PCA). In the previous post, we learned that we need to apply this method to construct a parametric face model. In order to better understand the whole process let’s remind ourselves what is PCA and how it works. The theoretical explanation of the PCA in this post is based on the YouTube video “3D Scanning & Motion…
