Wood texture 1
This picture is intended for the use of the 3D environment. I plan on using this as a daytime variant of the wall due to how it is much brighter than the alternative. First I wanted to reduce the reflection on it, so I selected the brighter section of the

3D Theory
Geometric Theory
Geometric Theory is the creation and editing of a 3D object, using multiple 2D polygons. Vertices, Edges, and polygons are used in this which are made up of lines and surfaces.
Edges
Edges are the lines on a polygon that make up the outline of the surface. Each edge is made up of a line and 2 vertices, each one on the edge of the line. Edges do not require the polygon that it makes up but do need vertices to show where the line starts and ends. Removing the surface of the shape will allow you to see the outline more clearly.
Vertices
Vertices are points which are given X, Y, Z coordinates to determine the exact position of them. They are found at the end of a line to make an edge and can be connected to multiple edges to form a shape.
Polygons
Polygons are 2D shapes which are made up of 3 or more edges. These shapes are used multiple times to create a 3D object. At least 2 polygons must be produced to make an object 3D. Each type of polygon has a certain number of edges:
-
Shapes with 3 edges are called trigons, they are triangle shaped.
-
Shapes with 4 edges are called quadgons, they are quadrilaterals.
-
Shapes with 5 or more edges are called n-gons, they are polygons with 5 or more edges.
The polycount of an object is the number of edges, vertices, and polygons on a model. The higher the polycount the more detailed the model will be. However, when putting the model into an engine, you will want the lowest number of polygons possible, to ensure it is well optimized, otherwise, the performance will be affected.
Lines
Lines are the connections between 2 different vertices to create the edge of a polygon. Multiple lines are put together to create a 2D polygon.
Surfaces
Surfaces are the faces of a shape. The corners of the surfaces are connected to vertices and the edges of a shape. Multiple surfaces are needed to transform shape from 2D to 3D.
Element
An element is multiple edges, vertices, and surfaces being put together to make a 3D object.
Meshes
A mesh is a combination of polygons that are connected to make a shape. The mesh is the structure of the Model and uses coordinates to build itself using different programs. A mesh can be comprised of a large or small number of polygons. A mesh with less polygons will make it easier to see the edges.
Wireframe
A wireframe mesh is a display of an element without any surfaces. It outlines only the edges of the model. This display is useful when viewing images of a certain view of an object behind an element when looking at it through a side view.
Primitives
Primitives are the prefab shapes used in 3D modeling software that can be used or edited on your model to create more complex shapes. These shapes are basic but can be edited in any way to create something else. The types of Primitives include:
-
Cubes
-
Spheres
-
Cylinder
-
Cone
-
Pyramid
-
Plane
A plane is a 2D primitive shape which can only be viewed from one side.
Co-ordinate Geometry
It’s a type of geometry in which the points on a plane are defined by coordinates in 3 dimensions. These coordinates are stored when a model is exported so when it is used in a different program is knows the exact position each vertex should be placed in.
