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:
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.
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) |
Holds the current diffuse map texture.
By default, the diffuse texture has the following properties:
Access functions:
Qt3DRender::QAbstractTexture * | diffuse() const |
void | setDiffuse(Qt3DRender::QAbstractTexture *diffuse) |
Notifier signal:
void | diffuseChanged(Qt3DRender::QAbstractTexture *diffuse) |
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) |
Holds the current specular map texture.
By default, the specular texture has the following properties:
Access functions:
Qt3DRender::QAbstractTexture * | specular() const |
void | setSpecular(Qt3DRender::QAbstractTexture *specular) |
Notifier signal:
void | specularChanged(Qt3DRender::QAbstractTexture *specular) |
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) |
