Geometric theory uses 3D lighting tricks that employ an extra axis compared to 2D design. Basic objects in mesh modeling include vertices and polygons formed by connecting vertices with edges. Triangles made of three connected vertices are the simplest 2D figures. Surfaces of connected polygons with shared vertices are called meshes, also known as wireframe models, which are useful for simulating light transport in ray tracing.

Geometric Theory
3D lighting tricks use constant principles found in second vector design, however use an
extra axis. Once making second vector design, the pc attracts the image by plotting points
on X and Y axes (creating coordinates) and connection these points with methods (lines).
The following shapes will be crammed with colour and therefore the lines stroked with
colour and thickness if needed.
Geometric Theory and Polygons
The basic object employed in mesh modelling may be a vertex, a degree in 3 dimensional
houses. 2 vertices connected by a line become a footing. 3 vertices, connected to every
different by 3 edges, outline a triangle, that is that the simplest two-dimensional figure in
metric space.
Surfaces
Surface normal area unit helpful for crucial lightweight transport in ray tracing. A group of
polygons that area unit connected by shared vertices is named as a mesh, typically ferried to
as a wireframe model.
