## Detailed Description

The QDiffuseSpecularMapMaterial provides a default implementation of the phong lighting and bump effect where the diffuse and specular light components are read from texture maps.

The specular lighting effect is based on the combination of 3 lighting components ambient, diffuse and specular. The relative strengths of these components is controlled by means of their reflectivity coefficients which are modelled as RGB triplets:

- Ambient is the color that is emitted by an object without any other light source.
- Diffuse is the color that is emitted for rought surface reflections with the lights.
- Specular is the color emitted for shiny surface reflections with the lights.
- The shininess of a surface is controlled by a float property.

This material uses an effect with a single render pass approach and performs per fragment lighting. Techniques are provided for OpenGL 2, OpenGL 3 or above as well as OpenGL ES 2.

## Property Documentation

### ambient : QColor

Holds the current ambient color.

Access functions:

QColor | ambient() const
void | setAmbient(const QColor &ambient)

Notifier signal:

void | ambientChanged(const QColor &ambient)

### diffuse : Qt3DRender::QAbstractTextureProvider *

Holds the current diffuse map texture.

By default, the diffuse texture has the following properties:

- Linear minification and magnification filters
- Linear mipmap with mipmapping enabled
- Repeat wrap mode
- Maximum anisotropy of 16.0

Access functions:

QAbstractTextureProvider * | diffuse() const
void | setDiffuse(QAbstractTextureProvider *diffuse)

Notifier signal:

void | diffuseChanged(QAbstractTextureProvider *diffuse)

### shininess : float

Holds the current shininess as a float value.

Access functions:

float | shininess() const
void | setShininess(float shininess)

Notifier signal:

void | shininessChanged(float shininess)

### specular : Qt3DRender::QAbstractTextureProvider *

Holds the current specular map texture.

By default, the specular texture has the following properties:

- Linear minification and magnification filters
- Linear mipmap with mipmapping enabled
- Repeat wrap mode
- Maximum anisotropy of 16.0

Access functions:

QAbstractTextureProvider * | specular() const
void | setSpecular(QAbstractTextureProvider *specular)

Notifier signal:

void | specularChanged(QAbstractTextureProvider *specular)

### textureScale : float

Holds the current texture scale as a float value.

Access functions:

float | textureScale() const
void | setTextureScale(float textureScale)

Notifier signal:

void | textureScaleChanged(float textureScale)
