As of 2021, official releases of Blender for Microsoft Windows, macOS and Linux, [241] as well as a port for FreeBSD, [242] are available in 64-bit versions. Blender is available for Windows 8.1 and above, and Mac OS X 10.13 and above. [243] [244] Blender 2.80 was the last release that had a version for 32-bit systems (x86). [245]
This process takes that mesh and subdivides it, creating new vertices and new faces. The positions of the new vertices in the mesh are computed based on the positions of nearby old vertices, edges, and/or faces. In many refinement schemes, the positions of old vertices are also altered (possibly based on the positions of new vertices).
The subdivide tool splits faces and edges into smaller pieces by adding new vertices. For example, a square would be subdivided by adding one vertex in the center and one on each edge, creating four smaller squares. The extrude tool is applied to a face or a group of faces. It creates a new face of the same size and shape which is connected to ...
A simple list of vertices, and a set of polygons that point to the vertices it uses. Winged-edge in which each edge points to two vertices, two faces, and the four (clockwise and counterclockwise) edges that touch them. Winged-edge meshes allow constant time traversal of the surface, but with higher storage requirements. Half-edge meshes
The doubly connected edge list (DCEL), also known as half-edge data structure, is a data structure to represent an embedding of a planar graph in the plane, and polytopes in 3D. This data structure provides efficient manipulation of the topological information associated with the objects in question (vertices, edges, faces).
A triangle t = hv0,v1,v2i has vertices v0, v1, and v2. It has edges e0 = hv0,v1i, e1 = hv1,v2i, and e2 = hv2,v0i. The inverse connections are also known. Vertex v0 is adjacent to edges e0 and e2 and to triangle t. Vertex v1 is adjacent to edges e0 and e1 and to triangle t. Vertex v2 is adjacent to edges e1 and e2 and to triangle t.
Basically, a 3D model is formed from points called vertices that define the shape and form polygons. A polygon is an area formed from at least three vertices (a triangle). A polygon of n points is an n-gon. [10] The overall integrity of the model and its suitability to use in animation depend on the structure of the polygons.
