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.

void | setAmbient (const QColor & ambient ) |

Holds the current diffuse map texture.
By default, the diffuse texture has the following properties:
访问函数:
Qt3DRender::QAbstractTexture * | diffuse () const |
void | setDiffuse (Qt3DRender::QAbstractTexture * diffuse ) |
通知程序信号:
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.
访问函数:
float | shininess () const |
void | setShininess (float shininess ) |
通知程序信号:
void | shininessChanged (float shininess ) |
Holds the current specular map texture.
By default, the specular texture has the following properties:
访问函数:
Qt3DRender::QAbstractTexture * | specular () const |
void | setSpecular (Qt3DRender::QAbstractTexture * specular ) |
通知程序信号:
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.
