Normals and Vertex Arrays
Login and open two windows, one for editing and one for compiling
and executing programs.
A = ( 3, 0, 2 ) and B = ( 4, 1, 8 ). Find
A x B,
B x A, and
A.B,
Find the normal vector to the plane that passes through the
points (1, 1, 1), (1, 2, 1), and ( 3, 0, 4 )
(0.1 EC ) Write a simple program to find the normal to a plane passing
through three points.
Then use your program to check if the normal that you found in
above is correct.
