TITLE : Chapter 13. Evaluators and NURBS
The GLU_AUTO_LOAD_MATRIX property determines whether the projection matrix, modelview matrix, and viewport are downloaded from the OpenGL server (GL_TRUE, the default), or whether the application must supply these matrices with gluLoadSamplingMatrices() (GL_FALSE)........

TITLE : Chapter 13. Evaluators and NURBS
If the GLU_AUTO_LOAD_MATRIX is turned off, the modelview and projection matrices and the viewport specified in gluLoadSamplingMatrices() are used to compute sampling and culling matrices for each NURBS curve or surface........

TITLE : EDM/2 - OpenGL and OS/2 - All About NURBS
value is Boolean. GL_TRUE means that the NURBS code automatically uses the current projection, modelview and viewport matrices to compute sampling and culling matrices for each curve rendered. GL_FALSE requires the user to specify matrices with gluLoadSamplingMatrices()........
