Task 1C: Calculate the Specular Lighting Term
Preparation
Locate $TASK 1C in the CgFX file 'carscene-1.fx'.
Description
The reflective properties of a shiny surface creates highlights which are strongest when the eye vector is parallell to the reflection direction. The specular lighting term is thus view dependent since the appearance of a particular surface changes as the eye moves relative the object. For further details see Chapter 4.3.2 in the course book.
Hint
In order to compute x to the power of y, use the intrinsic pow.
