GameDev: Modeling Categories and Approaches (Part 1) & Polygonal and Box Modeling (Part 2)

Modeling

It involves creating or recreating the shape of an object

additive,

subtractive

In a broader sense, you can consider an _________________ approach or a __________________ approach, like sculpting an object from a block of wood or stone.

primitives

In computer graphics, a set of objects known as ________________________ are used to approximate simple geometric shapes

primitives

these can be as simple as a point or can be a 2D or 3D object such as a line or a face or a box.

primitives

It can serve as the starting point for many models

polygons,

faces

In polygonal modeling, the 3D scene objects are generated by putting together many flat surfaces, known as _______________________ or _____________________.

Polygonal models

are commonly used in graphics applications as they are not only simple to define in terms of storing within a database, but they are also easy to transform, manipulate, and display.

3D objects

are modeled using polygon meshes to recreate the surface that is being approximated, which is typically four-sided quadrilaterals (quads) or three sided triangles (tris)

polygon meshes

3D objects are modeled using ________________________ to recreate the surface that is being approximated, which is typically four-sided quadrilaterals (quads) or three sided triangles (tris)

quads,

tris

3D objects are modeled using polygon meshes to recreate the surface that is being approximated, which is typically four-sided quadrilaterals (______________) or three sided triangles (_____________)

n-gons

In addition to tris or quads, polygons with more than four sides, namely n-______________, are also used for polygonal modeling

polygonal models

Generally, ______________________ are relatively more convenient to create and to render, especially when it comes to organic modeling, polygonal meshes can be quite useful and efficient

organic modeling

Generally, polygonal models are relatively more convenient to create and to render, especially when it comes to __________________________, polygonal meshes can be quite useful and efficient

time-consuming

However, polygonal modeling can be ____________________________, especially when dealing with sophisticated designs requiring elaborate modeling.

flat surfaces

Another shortcoming of polygonal modeling is that it requires many _____________________________ to avoid faceted appearance of the final models created.

faceted appearance

Another shortcoming of polygonal modeling is that it requires many flat surfaces to avoid _____________________________ of the final models created.

E B B C

here are different ways to distort a polygonal model to suit the looks of an object: What are those 4?

Extrusion

refers to selecting a face from a polygonal mesh or an edge and pulling it out.

Bevel

this refers to the creation of inclined surfaces, and can be referred to inward bevel or outward bevel

inward,

outward

What are the two types of bevel

Bridge

an operation where the edges of the polygons can be bridged together to create objects by combining two 3D objects

Constructive Solid Geometry

refers to the use of Boolean Operations (AND, OR, NOT) to create complex designs and intricate shapes

Box modeling

is a common technique for 3D modeling compound scene models that are composed of multiple parts.

Box modeling

involves starting with a standard primitive object such as a cube and then working with the sub-objects like faces and edges by transforming and modifying them in different ways

Box modeling

It can be used to create both organic models and hard-surface models.
