WebSteps in the Initialization Process. Name the texture. Bind the texture to its name. Specify the parameters to use. Specify an application mode (either replace or modulate ) Create the texture object. Enable texture mapping. WebOpenGL supports several types of textures such as 1D, 2D, 3D, cube, etc that can be used for different techniques. Let's stick with 2D textures for now. A 2D texture has a width and height that can be any number within the limitations of the spec. Multiplying the width by height tells you the number of texels in the texture. Like any of the previous objects in OpenGL, textures are referenced with an ID; let's create one: The glGenTextures function first takes as input how many textures we want to generate and stores them in a unsigned int array given as its second argument (in our case just a single unsigned int).
