HW4 grading clarifications
The grading of the final HW will be different from previous homeworks,
YOU are required to present the features you chose to implement,
by presenting the final images you produce, and we may ask you
to reproduce some of them with your renderer,
so make sure to be equipped with whatever you need to demonstrate
it on your renderer (images, models,...).

We remind you to send Fady up to 5 images for the competition before 25/1

Good luck.

HW3 clarifications - Normal correction

There are two places where you need to use the normals:

1) For backface culling, you need to use the face normal to perform the
backface test. Because the normals are distorted after perspective projection,
you"ll need to recalculate it again.

2) Vertices normals for light calculation:
In this case your are not required to recalculate the vertices normals after perspective,
nor after non uniform scaling, since it requires a more complicated data structures of adjancies.
you can assume only translation and rotation and uniform scaling.

Clarification regarding Hw2
In this assignment you are to draw the objects as wireframe (lines).
To be crystal clear, you should use no external library/function call
to draw the lines - the lines should be drawn using your implementation
of the algorithm presented in class:

The Bresenham/Midpoint/DDA algorithm.

As in Hw1, only 'Plot Pixel' function call can be used.

If you find it easier, you can use a floating point version of the algorithm
