Tutorials# Hello Triangle! In this tutorial, we will create a simple “hello triangle,” which is a “hello world” of graphics programming, using DRTK. Simplest Case of Geometry Optimization In this tutorial, we will see how to setup a minimal example of geometry optimization. Optimizing Intersecting Geometry In this tutorial, we demonstrate geometry effectively optimization when intersections are present. Rendering meshes In this tutorial, we demonstrate how to rendering simple meshes with DRTK. Single image hand fitting In this tutorial, we demonstrate fitting of a simple hand model with simple lambertian material to a single photo.
