Cyrus Beck Triangle Clip: Window
Use Polar to Cartesian conversion to
obtain the three normal vectors
because normal vectors are unit vectors]
While Calculating t values,
you can pick any point on that
enge for "PE.
For example: While working with bottom
edge, you can pick the vertex (-4,0) as "P PEQuestion 4- Cyrus-Beck Line Clipping
6+9=15
A triangular clipping window is defined by the vertices {(-4,0),(4,0),(0,4)}, as shown
in the picture above. Everything inside the triangle will be kept, the rest will be
discarded
a) Calculate the normals vectors for each of the edges. Please remember that the
normals should point outside the triangle and they will be unit vectors.
b) Using the Cyrus-Beck Line Clipping Algorithm, calculate the clipping points for
the line segment that goes from (-4,4) to (3,-1). Show detailed calculation,
including the calculation of t values, PE/PL grouping.
