In this article, I will introduce the reader to the Physics system used in the Unity game engine. First, I will introduce the Physic Material Asset that is used to define physics properties for collider surfaces. I will also introduce Colliders and talk about the different kinds of Collider types you can create. The Rigidbody component is absolutely essential for performing physics simulations on GameObjects. I will show you how you can create a Rigidbody GameObject that can be user controlled. I will also talk about the Character Controller component that is provided by Unity to control upright characters. And finally, I will introduce the different Joints that are available in Unity.
In this article, I will introduce the reader to the different rendering components in Unity. I will introduce the Camera component as well as the different lighting components that are available. I will also talk about materials in Unity and introduce you to a few of the shaders that are available. And finally, I will also introduce light-mapping in Unity.
In this article, I will introduce you to scripting in Unity 3.5. Unity is a powerful game editor that only limits you to what you can imagine. Scripting is where the magic happens which will bring your games to life. I assume the reader is familiar the Unity interface, if not you can refer to my previous article titled Introduction to Unity (http://3dgep.com/?p=3246).
In the previous article titled Introduction to Unity 3.5 I introduced the Unity interface and we created a simple project that shows a rotating cube. In this article, I want to introduce some basic Unity concepts such as the Asset pipeline and the GameObject-Component model and introduce a few of the Components that Unity provides. I will not go into too much detail about the different components in this article (I will dedicate a different article for each of the more complex components such as Terrain, Particle Effects, Physics, Audio, and Scripts).
In this article, I will introduce you to the Unity game editor. Unity is a tool for creating and deploying games to PC, consoles, web and mobile devices. In this post, I will go through the steps to get Unity installed on your computer and I will introduce you to the basic features of Unity. Unity makes it easy for anyone to get started making games. You will not need any previous game development experience to follow these articles but by the end, you will be prepared to start making your own games like a professional!
In this article I will attempt to explain the concept of Quaternions in an easy to understand way. I will explain how you might visualize a Quaternion as well as explain the different operations that can be applied to quaternions. I will also compare applications of matrices, euler angles, and quaternions and try to explain when you would want to use quaterions instead of Euler angles or matrices and when you would not.
In this article I will demonstrate how to implement a basic lighting model using the Cg shader language. If you are unfamiliar with using Cg in your own applications, then please refer to my previous article titled Introduction to Shader Programming with Cg 3.1.
This article is an updated version of the previous article titled Transformation and Lighting in Cg. In this article, I will not use any deprecated features of OpenGL. I will only use the core OpenGL 3.1 API.
In this article I will introduce the reader to shader programming using the Cg shader programming language. I will use OpenGL graphics API to communicate with the Cg shaders. This article does not explain how use OpenGL. If you require an introduction to OpenGL, you can follow my previous article titled Introduction to OpenGL.
In this article, I will explain how to use the ARB_vertex_buffer_object extension to efficiently render geometry in OpenGL.
If you are not sure how to use extensions in OpenGL, you can refer to my previous article titled OpenGL Extensions. If you have never programmed an OpenGL application before, you can refer to my previous article titled Introduction to OpenGL.
In this article I will talk about OpenGL extensions. Every extension is defined by an extension specification. I will explain how to read the extension specification so that you will know how to use the extensions. I will also show how you can check for the existence of extensions and how to initialize extensions in your own source code. I will show how you can use GLEW to query and use extensions with very little extra effort.
I assume the reader is familiar with the C++ programming language. If you want to know how to start programming in OpenGL, refer to my previous article titled Introduction to OpenGL.
