X → Mesh Conversions

This topic provides a reference table for all automatic type conversions to mesh, sorted by merit.

Direct Conversions

This section lists all direct conversions to the mesh type. A 'Direct' conversion indicates a relation between very related types, such as integers and numbers, or 2D and 3D points. Though note that even these conversions can fail due to out-of-bounds issues, or be narrowing due to reduction.

From	Explanation
region	Triangulates the region into a mesh.

Fair Conversions

This section lists all fair conversions to the mesh type. A 'Fair' conversion indicates the types involved are closesly related in a data layout sense, though not necessarily in a conceptual sense. For example booleans and integers, or points and vectors. Although these conversions may fail or narrow, it is nevertheless considered decent practice to rely upon them in algorithms.

From	Explanation
box	Creates a box mesh with one facet per side.
brep	Creates a mesh approximation of a surface.
cage	A mesh whose vertices lie on the naked points of the cage is created.
rectangle	Creates a single facet mesh covering the interior of the rectangle.
sphere	Creates a low polygon approximation of the sphere.
SubD	Creates a mesh representing the control polytope of the SubD.
surface	Creates a mesh approximation of a surface.
tube	Creates a low polygon approximation of the tube.

Plausible Conversions

This section lists all plausible conversions to the mesh type. A 'Plausible' conversion indicates a non-straightforward, but a still reasonable conversion between two types that share a salient quality, or where one is an obvious sub-type of the other. For example curves and intervals, or points and planes. Any plausible conversion can also be achieved through the explicit use of standard components.

From	Explanation
identifier	Duplicates the referenced Rhino mesh object.

Strange Conversions

This section lists all strange conversions to the mesh type. A 'Strange' conversion indicates a peculiar, but occasionally sensible, translation between types. However, it is equally likely that the conversion was not intended and thus represents a mistake in the algorithm design, which is why this conversion level is the default for showing conversion warnings in the Grasshopper interface. Examples in this category include the conversion between colours and booleans, or between circles and triangles. Any strange conversion can also be achieved through the explicit use of standard components.

From	Explanation
plane	Creates a unit sized mesh on the plane.
view	Create a mesh representing the view frustum.
