| Linear algebra in [[LinearAlgebra2D|2D]] and [[LineareAlgebra3D|3D]] processes all these formats when loading from a file. | Linear algebra in [[LinearAlgebra2D|2D]] and [[LineareAlgebra3D|3D]] processes all these formats when loading from a file. |
| Points are summarised in the process: in 2D space, point sequences are created, while in 3D space, point clouds are created, as is also the case with [[ImpliziteFlaechen|implicit surfaces]]. All points within a file are combined into a single point sequence or cloud. If 3D objects are loaded in [[LinearAlgebra2D|Linear Algebra for 2D]], they lose their z-extension and are therefore displayed flat. Spheres become circles. Conversely, 2D objects can be loaded in [[LineareAlgebra3D|linear algebra for 3D]], but then have no z-extension and are displayed in the x-y plane. The only exception is 3D circles; these will not be displayed in 2D. | Points are summarised in the process: in 2D space, point sequences are created, while in 3D space, point clouds are created, as is also the case with [[ImpliziteFlaechen|implicit surfaces]].

| For [[interpolations]], files that only have two columns for the x and y coordinates of the values can also be used. A single-column format is also possible – in this case, the x values are first added consecutively starting from zero. They can then be [[interpolations#converting_values|converted]] later. | For [[interpolations]], files that only have two columns for the x and y coordinates of the values can also be used.
