NormalDiffuseSpecularMapMaterial QML Type
The NormalDiffuseSpecularMapMaterial provides a default implementation of the phong lighting and bump effect where the diffuse and specular light components are read from texture maps and the normals of the mesh being rendered from a normal texture map. More...

Detailed Description
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
diffuse : TextureImage |
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
normal : TextureImage |
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
specular : TextureImage |
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
Holds the current texture scale. It is applied as a multiplier to texture coordinates at render time. Defaults to 1.0.
