Question

What is the name of the small integer which holds a bit for the result of every plane test?​

Answer 1

The name of the small integer is the out c ode

• It typically represents a small fraction that properly consists of a bit for the desired result of any plane test breaking down in clipping.
• If the bitwise of all its vertices out c odes is not zero, primitives can be easily rejected.
• Generally, for the two-dimensional clipping, the out c ode will remain four bits, and for the three-dimensional clipping, it will be typically six bits.
