In order to correctly map the texture to a model we must specify a texture coordinate to each vertex of the model. Textures can provide much more detail to the model that would otherwise only be possible by creating models with a huge number of vertices. Texture mapping is the process of applying a 2D (or 3D) image to a 3D model. You can download the updated version of SOIL here: I fixed this issue and provided a solution and project files for Visual Studio 2012 (vs11) that you can use for your own projects. The Simple OpenGL Image Library provided from the link above had some issues when using it with an OpenGL 3.0 or higher forward-compatible context when it queries for extension support. You can get the latest version of SOIL here: With a single method, you can load textures and get an OpenGL texture object. SOIL: The Simple OpenGL Image Library is the easiest way that I am currently aware of to load textures into OpenGL.This makes writing math functions in C++ very similar to the math functions you will see in GLSL shader code. OpenGL Math Library (GLM 0.9.5): The OpenGL math library is written to be consistent with the math primitives provided by the GLSL shading language.OpenGL Extension Wrangler (GLEW 1.10.0): The OpenGL Extension Wrangler library provides accessibility to the OpenGL core and extensions that may not be available in the OpenGL header files and libraries provided by your compiler.The purpose of the GLUT library is to provide window, keyboard, and mouse functionality in a platform-independent way. Free OpenGL Utility Toolkit (FreeGLUT 2.8.1): FreeGLUT is an open-source alternative to the OpenGL Utility Toolkit (GLUT) library.Dependenciesįor this article, I will rely on several 3rd party libraries to simplify programming. In this article, I will describe how to apply texturing, lighting and materials using OpenGL and GLSL. A model can appear very shiny or very dull depending on the material properties of the model. Materials are used to determine how the light interacts with the surface of the model. With the correct use of lighting we can make a scene dark and gloomy or bright and cheery. Lighting also provides a cue to the eye what the direction and shape of an object has.

Lighting is required to set the mood for a scene. As you can imagine, adding detail to a model in this way can be very inefficient. Without textures the only way to acquire the level of detail that can be achieved using texture mapping would be to specify a different colored vertex for each pixel of the screen. Texturing an object is the process of mapping a 2D (or sometimes 3D) image onto a 3D model so that you can achieve much higher detail in the model without using a lot of vertices. 4.3.4 The Phong, and Blinn-Phong Lighting Models.
