WebDescription. glLight sets the values of individual light source parameters.light names the light and is a symbolic name of the form GL_LIGHT i, where i ranges from 0 to the value of GL_MAX_LIGHTS - 1. pname specifies one of ten light source parameters, again by symbolic name.params is either a single value or a pointer to an array that contains the … Web[4]: First we create an identity matrix translated by a vector to push the matrix 10 units back into the scene.This puts our teapot right at the center of the screen but a little bit far off. [5]: We then create a rotation matrix from the previously defined matrix that rotates the teapot around the y-axis depending on the rendering frame counter.This will also make the …
