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 rough 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.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property ambientᅟ: QColor

Holds the current ambient color that is emitted by an object without any other light source.

Access functions:

• ambient()

• setAmbient()

• Signal ambientChanged()

property diffuseᅟ: 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:

• diffuse()

• setDiffuse()

• Signal diffuseChanged()

property shininessᅟ: float

Holds the current shininess as a float value. Higher values of shininess result in a smaller and brighter highlight.

Defaults to 150.0.

Access functions:

• shininess()

• setShininess()

• Signal shininessChanged()

property specularᅟ: 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:

• specular()

• setSpecular()

• Signal specularChanged()

property textureScaleᅟ: 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:

• textureScale()

• setTextureScale()

• Signal textureScaleChanged()
