The following line tells OpenGL the texture will be a 2D texture (GL_TEXTURE_2D). Zero represents the images level of detail, this is usually left at zero. 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. WebAs long as a direction is supplied, OpenGL retrieves the corresponding texels that the direction hits (eventually) and returns the properly sampled texture value.
