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.

class PySide6.Qt3DExtras.Qt3DExtras.QDiffuseMapMaterial([parent=None])

Parameters

parent – PySide6.Qt3DCore.Qt3DCore.QNode

Constructs a new QDiffuseMapMaterial instance with parent object parent.

PySide6.Qt3DExtras.Qt3DExtras.QDiffuseMapMaterial.ambient()

Return type

PySide6.QtGui.QColor

Holds the current ambient color.

PySide6.Qt3DExtras.Qt3DExtras.QDiffuseMapMaterial.ambientChanged(ambient)

Parameters

ambient – PySide6.QtGui.QColor

PySide6.Qt3DExtras.Qt3DExtras.QDiffuseMapMaterial.diffuse()

Return type

PySide6.Qt3DRender.Qt3DRender.QAbstractTexture

Holds the current texture used as the diffuse map.

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

PySide6.Qt3DExtras.Qt3DExtras.QDiffuseMapMaterial.diffuseChanged(diffuse)

Parameters

diffuse – PySide6.Qt3DRender.Qt3DRender.QAbstractTexture

PySide6.Qt3DExtras.Qt3DExtras.QDiffuseMapMaterial.setAmbient(color)

Parameters

color – PySide6.QtGui.QColor

Holds the current ambient color.

PySide6.Qt3DExtras.Qt3DExtras.QDiffuseMapMaterial.setDiffuse(diffuse)

Parameters

diffuse – PySide6.Qt3DRender.Qt3DRender.QAbstractTexture

Holds the current texture used as the diffuse map.

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

PySide6.Qt3DExtras.Qt3DExtras.QDiffuseMapMaterial.setShininess(shininess)

Parameters

shininess – float

Holds the current shininess as a float value.

PySide6.Qt3DExtras.Qt3DExtras.QDiffuseMapMaterial.setSpecular(specular)

Parameters

specular – PySide6.QtGui.QColor

Holds the current specular color.

PySide6.Qt3DExtras.Qt3DExtras.QDiffuseMapMaterial.setTextureScale(textureScale)

Parameters

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, 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.

PySide6.Qt3DExtras.Qt3DExtras.QDiffuseMapMaterial.shininess()

Return type

float

Holds the current shininess as a float value.

PySide6.Qt3DExtras.Qt3DExtras.QDiffuseMapMaterial.shininessChanged(shininess)

Parameters

shininess – float

PySide6.Qt3DExtras.Qt3DExtras.QDiffuseMapMaterial.specular()

Return type

PySide6.QtGui.QColor

Holds the current specular color.

PySide6.Qt3DExtras.Qt3DExtras.QDiffuseMapMaterial.specularChanged(specular)

Parameters

specular – PySide6.QtGui.QColor

PySide6.Qt3DExtras.Qt3DExtras.QDiffuseMapMaterial.textureScale()

Return type

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, 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.

PySide6.Qt3DExtras.Qt3DExtras.QDiffuseMapMaterial.textureScaleChanged(textureScale)

Parameters

textureScale – float
