QNormalDiffuseMapMaterial Class
(Qt3DExtras::QNormalDiffuseMapMaterial)The QNormalDiffuseMapMaterial provides a default implementation of the phong lighting and bump effect where the diffuse light component is read from a texture map and the normals of the mesh being rendered from a normal texture map. More...

Detailed Description
This class is deprecated; use 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 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 these properties:
- Linear minification and magnification filters
- Linear mipmap with mipmapping enabled
- Repeat wrap modeM
- Maximum anisotropy of 16.0
Access functions:
| Qt3DRender::QAbstractTexture * | diffuse() const | 
| void | setDiffuse(Qt3DRender::QAbstractTexture *diffuse) | 
Notifier signal:
| void | diffuseChanged(Qt3DRender::QAbstractTexture *diffuse) | 
normal : Qt3DRender::QAbstractTexture*
Holds the current normal map texture.
By default, the normal texture has the following properties:
- Linear minification and magnification filters
- Repeat wrap mode
- Maximum anisotropy of 16.0
Access functions:
| Qt3DRender::QAbstractTexture * | normal() const | 
| void | setNormal(Qt3DRender::QAbstractTexture *normal) | 
Notifier signal:
| void | normalChanged(Qt3DRender::QAbstractTexture *normal) | 
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 : QColor
Holds the current specular color.
Access functions:
| QColor | specular() const | 
| void | setSpecular(const QColor &specular) | 
Notifier signal:
| void | specularChanged(const QColor &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) |
