## Detailed Description

This class is deprecated; use Qt3DExtras::QDiffuseSpecularMaterial instead.

The specular lighting effect is based on the combination of 3 lighting components ambient, diffuse and specular. The relative strengths of these components are 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 rough 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 that is emitted by an object without any other light source.

Access functions:

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

Notifier signal:

void | ambientChanged(const QColor &ambient)

### diffuse : Qt3DRender::QAbstractTexture*

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:

Qt3DRender::QAbstractTexture * | diffuse() const
void | setDiffuse(Qt3DRender::QAbstractTexture *diffuse)

Notifier signal:

void | diffuseChanged(Qt3DRender::QAbstractTexture *diffuse)

### shininess : float

Holds the current shininess as a float value. Higher values of shininess result in a smaller and brighter highlight.

Defaults to 150.0.

Access functions:

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

Notifier signal:

void | shininessChanged(float shininess)

### specular : Qt3DRender::QAbstractTexture*

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:

Qt3DRender::QAbstractTexture * | specular() const
void | setSpecular(Qt3DRender::QAbstractTexture *specular)

Notifier signal:

void | specularChanged(Qt3DRender::QAbstractTexture *specular)

### textureScale : float

Holds the current texture scale. It is applied as a multiplier to texture coordinates at render time. Defaults to 1.0.

Access functions:

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

Notifier signal:

void | textureScaleChanged(float textureScale)

## Member Function Documentation

### QDiffuseSpecularMapMaterial::QDiffuseSpecularMapMaterial(Qt3DCore::QNode *parent = nullptr)

Constructs a new QDiffuseSpecularMapMaterial instance with parent object parent.
