As with other OpenGL objects, there are functions to generate, bind, and delete sampler objects:

• void glGenSamplers(GLsizei n​, GLuint *samplers​);
• void glBindSampler(GLuint unit​, GLuint sampler​);
• void glDeleteSamplers(GLsizei n​, const GLuint *samplers​);

A sampler object’s parameters can then be changed using

• void glSamplerParameter*(GLuint sampler​, GLenum pname​, GLint param​);

In the template code, a sampler object is created automatically for each texture as part of the CTexture class.  A method

CTexture::SetSamplerObjectParameter[f]()

can be used to a set a parameter using the sampler object.
