Trilinear may refer to:
*
Trilinear filtering
Trilinear filtering is an extension of the bilinear texture filtering method, which also performs linear interpolation between mipmaps.
Bilinear filtering has several weaknesses that make it an unattractive choice in many cases: using it on a ...
, a method in computer graphics for choosing the color of a texture
*
Trilinear form, a type of mathematical function from a vector space to the underlying field
*
Trilinear interpolation
Trilinear interpolation is a method of multivariate interpolation on a 3-dimensional regular grid. It approximates the value of a function at an intermediate point (x, y, z) within the local axial rectangular prism linearly, using function data ...
, an extension of linear interpolation for interpolating functions of three variables on a rectilinear 3D grid
*
Trilinear map, a type of mathematical function between vector spaces
*
Trilinear coordinates
In geometry, the trilinear coordinates of a point relative to a given triangle describe the relative directed distances from the three sidelines of the triangle. Trilinear coordinates are an example of homogeneous coordinates. The ratio is ...
*
Trilinear polarity
In Euclidean geometry, trilinear polarity is a certain correspondence between the points in the Plane (geometry), plane of a triangle not lying on the sides of the triangle and lines in the plane of the triangle not passing through the Vertex (g ...
