Maybe you have some knowledge of rendering via OpenGL or Vulkan, + and you want to begin watching your up-until-now static scene come to life. Well, you're in the right place! In the course of this tutorial series I will walk + you through the entirety of a 2D rigid body physics system entirely in the web. All of this information will be extendable to other languages, but we will use + JavaScript and WebGL in these blog posts. Additionally, much of the information presented here can be extended to 3 dimensions, but 3D carries some complications + with it, that we will discuss in future blog posts. + </p> + <p> + In implementing a rigidy body physics system, we're primarily interested in two sub-fields of physics, namely <b>dynamics</b> and <b>kinematics</b>. Although I'm + far as can be from being an expert in either of these fields, I will explain - from a programmer's persepctive - what they mean to me: + <ul> + <li> + <b>Kinematics</b> is the study of how an object's movement changes over time. These are the classic position, velocity, and acceleration equations + that you're most likely familiar with from high school or college physics. + </li> + <li> + <b>Dynamics</b> is the study of whats <i>causes</i> kinematic movement. These are the classic force and momentum equations that you may already be familiar + with as well. + </li> + </ul> + </p> + <p> + Finally, I must provide a disclaimer that all of rigid body systems are very math-y. You will need to know a decent amount of vector calculus and linear algebra to really understand + what's going on here. I am going to assume that you have this knowledge. If you don't already have this knowledge, I will try and provide some resources on the Books + n' References page of the website. + </p> + </section> +</article> + </main> + </body> +</html> |
