DiffuseSpecularMaterial QML Type

The DiffuseSpecularMaterial class provides a default implementation of the phong lighting effect. More...

Import Statement: import Qt3D.Extras 2.0
Since: Qt 5.10
Instantiates: QDiffuseSpecularMaterial


Detailed Description

The phong 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

alphaBlending : bool

Indicates if the alpha information coming from the diffuse property will be taken into account during rendering. Defaults to false.

ambient : color

Holds the ambient color.

diffuse : var

Holds the diffuse color of the material. This can be either a plain color value or a texture.

normal : var

Holds the current normal map texture of the material. This can only be a texture, otherwise it is ignored. By default this map is not set.

shininess : real

Holds the shininess exponent.

specular : var

Holds the specular color of the material. This can be either a plain color value or a texture.

textureScale : real

Holds the current texture scale. It is applied as a multiplier to texture coordinates at render time. Defaults to 1.0.
