# Default Phong Model

This model represents the standard Phong model, characterized by a shiny surface marked by pinpointed highlights. It allows for selecting and editing:

* `Diffuse Color`, `Texture`, and `Blending`
* `Specular Color`, `Texture`, and `Blending`
* `Normal Mapping`
* as well as tweaking `Shininess` and `Emissiveness`.

All these **Attributes** are described in greater detail below.

## Attributes

### Material

![Material](/files/y0c1qabDCHXdKefgxgwV)

This **Attribute** provides the `Name` of the **Material** as well as the `Shading model` type. It also sets the `Alpha` value if it is toggled on.

The `Alpha` channel is additional to the RGB channels and adds a kind of transparency to the object by mixing the background and foreground colors. For example, if the `Alpha` value is set to 0.5, then this would result in a 50% mix of the object and its background, providing a somewhat see-through quality.

### Diffuse

![Diffuse](/files/FkAXVOJIHedEGseQvBqi)

`Color` of `Diffuse` sets the base diffuse color of the model.

`Texture` takes any image to add any desired visual information.

Using `Blending`, the `Texture` and `Color` are combined. If `Blending` is set to 1 then 100% of the `Texture` is displayed on the **Object**. If 0.5, then it displays a 50/50 ratio of `Texture` and `Color`.

### Normals

![Normals](/files/8MS0v0HquKkFZRBsV52n)

A normal is a line perpendicular to the surface of some object. *Normal mapping* distorts these normals and simulates a surface with light and shadow, even if the object surface itself is flat. This is only possible with a light source. The `Normal Map` sets this surface and `Use Normal Map` toggles it on and off.

### Specular

![Specular](/files/lr88OZWkZ2E7jJdmuP6p)

`Specular` is the point of reflection of the light source.

`Color` sets the color of it.

`Texture` takes any image to add any desired visual information.

Using `Blending`, the `Texture` and `Color` are combined. If `Blending` is set to 1 then 100% of the `Texture` is displayed on the **Object**. If 0.5, then it displays a 50/50 ratio of `Texture` and `Color`.

### Tweak

![Tweak](/files/aQyeDMHkZBPUo2VWPzoa)

`Shininess` determines how 'shiny' a **Material** will be. This means that the higher the value, the 'harder' the surface looks at the smaller the reflection of light.

`Emissiveness` influences the color of items around an **Object**, simulating a light source. For example, the lights of a car combined with higher emissiveness will show a stronger glow on the surrounding car parts, with th car light's color interacting with its surroundings as well.
