Detailed Description
The QDiffuseSpecularMapMaterial provides a default implementation of the phong lighting 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 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 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::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.
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) |
