mesh
A collection of vertices, edges, and faces that defines the polyhedral shape of a 3D digital model in computer graphics and CAD.
In CAD, a mesh is the digital wireframe grid that represents the surface of an object, crucial for rendering and running physical simulations.
Word relationships
- wireframe: A wireframe shows only the lines (edges) of a model, while a mesh includes the faces (surfaces) formed by those lines.
- grid: A grid is typically a uniform, flat 2D network, whereas a mesh is a 3D network that conforms to complex, organic shapes.
- solid model: A solid model represents the volume of an object mathematically, rather than just its surface mesh.
Commonly confused with
- texture: A texture is a 2D image wrapped around a 3D model, while a mesh is the underlying 3D geometric structure itself.
Word family
- meshed (adjective): Interlocked or woven together like a net.
- meshing (noun): The act of generating a mesh or the interlocking of gear teeth.
Collocations
- polygon mesh
- mesh generation
- mesh density
- triangular mesh
Example sentences
- "If the polygon count of the mesh is too low, the curved surfaces of the model will look blocky." A tutorial on preparing a 3D model for a video game engine.
Memory hook
Think of a physical fishing 'mesh' net. If you throw that net over a statue, the net will cling to the shape, creating a digital-style 'mesh' of the object. Mesh is the digital net.
When not to use
Do not use to describe a solid, continuous mathematical model (like a NURBS model) that has not been broken down into polygons.
Fun facts
- In finite element analysis (FEA), engineers 'mesh' a model to break a complex structure into millions of tiny, simple shapes so the computer can calculate stress levels.
