Mesh Clipping Operations with OpenMesh Library
In this post, I will discuss the process of clipping operations on meshes using the OpenMesh library. For the purpose of this demonstration, we’ll utilize the OpenMesh library to represent our mesh. For those unfamiliar, OpenMesh provides extensive tools for manipulating polygonal meshes. We will be working with a triangulated mesh version for simplicity. Refer… Continue reading

Half-Edge Data Structure. Part 1
In this post I’ll describe my favorite mesh data structure called half-edge data structure. It’s used primarily in Mesh/CAD applications and helps to make various advanced operations on the mesh such as subdivision or simplification. Let’s start with the vertex and index buffer described in the previous post. The simplest way to display a model… Continue reading

Techniques for Showing and Hiding Triangles in 3D Meshes
In this post, I want to discuss how to hide and show triangles in a 3D meshes. This serves as a precursor to my next post, which will delve into my favorite sophisticated data structure: the half-edge data structure. I want to mention that I will be using some “abstract rendering API” for this post,… Continue reading
