Bilinear may refer to:
*
Bilinear sampling (also called "bilinear filtering"), a method in computer graphics for choosing the color of a texture
*
Bilinear form
In mathematics, a bilinear form is a bilinear map on a vector space (the elements of which are called '' vectors'') over a field ''K'' (the elements of which are called ''scalars''). In other words, a bilinear form is a function that is linear i ...

Bilinear interpolation, an extension of linear interpolation for interpolating functions of two variables on a rectilinear 2D grid
*
Bilinear map, a type of mathematical function between vector spaces
*
Bilinear transform
The bilinear transform (also known as Tustin's method, after Arnold Tustin) is used in digital signal processing and discrete-time control theory to transform continuous-time system representations to discrete-time and vice versa.
The bilinear t ...
