class QNormalDiffuseSpecularMapMaterial#

The QNormalDiffuseSpecularMapMaterial 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#

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.

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.

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 normalᅟ: 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:

normal()
setNormal()
Signal normalChanged()

property shininessᅟ: float#

Holds the current shininess as a float value.

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()
