Task 4 - Mesh Construction
How are 3D Models Constructed?
"This is a technique that is used in 3D modelling where the model is created by modifying primitive shapes to create a rough draft of the final model, in most cases. A primary function of box modeling involves extruding and scaling the faces, which are the flat planes that make up a model."
3D models are made up of polygons, the more polygons the higher quality the model will be, each model starts of with a primitive shape suck as a cube or a sphere, this makes it easier to build of of.
Primitive Modelling
Primitive Modeling is the basis of your 3d model, many shapes can be modeled from such as:
Cubes
Spheres
Cylinders
Pyramids
They're also 2D primitives, such as squares, triangles, and circles
"Primitives are the building blocks of 3D—basic geometric forms that you can use as is or modify with transforms and Booleans. Although it's possible to create most of these objects by lathing or extruding 2D shapes, most software packages build them in for speed and convenience."
Box Modelling
"A 3D modeling technique in which the artist begins with a low-resolution primitive (typically a cube or sphere) and modifies the shape by extruding, scaling, or rotating faces and edges. Detail is added to a 3D primitive either by manually adding edge loops, or by subdividing the entire surface uniformly to increase polygonal resolution by an order of magnitude."
Box model in is where you start of with a box the use different tools in a modeling software to create a 3D model.
Extrusion Modelling
"Extrusion is a method of adding geometry to a polygon primitive, and one of the primary tools a modeler uses to begin shaping a mesh.
Through extrusion a modeler manipulates the 3D mesh by either collapsing a face in upon itself (to create an indentation), or by extruding the face outward along its surface normal—the directional vector perpendicular to the polygonal face."
