This class is deprecated. We strongly advise against using it in new code.
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:
-
ambient() const
-
void setAmbient(const &ambient)
Notifier signal:
-
void ambientChanged(const &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:
-
*diffuse() const
-
void setDiffuse( *diffuse)
Notifier signal:
-
void diffuseChanged( *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:
-
*specular() const
-
void setSpecular( *specular)
Notifier signal:
-
void specularChanged( *specular)
textureScale : float▲
Holds the current texture scale. It is applied as a multiplier to texture coordinates at render time. Defaults to 1.0.
When used in conjunction with QTextureWrapMode::Repeat, textureScale provides a simple way to tile a texture across a surface. For example, a texture scale of 4.0 would result in 16 (4x4) tiles.
Access functions:
-
float textureScale() const
-
void setTextureScale(float textureScale)
Notifier signal:
-
void textureScaleChanged(float textureScale)
