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:

parentPySide6.Qt3DCore.Qt3DCore.QNode

Constructs a new QDiffuseMapMaterial instance with parent object parent.

Note

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

property PᅟySide6.Qt3DExtras.Qt3DExtras.QDiffuseMapMaterial.ambient: PySide6.QtGui.QColor#

Holds the current ambient color.

Access functions:
property PᅟySide6.Qt3DExtras.Qt3DExtras.QDiffuseMapMaterial.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

Access functions:
property PᅟySide6.Qt3DExtras.Qt3DExtras.QDiffuseMapMaterial.shininess: float#

Holds the current shininess as a float value.

Access functions:
property PᅟySide6.Qt3DExtras.Qt3DExtras.QDiffuseMapMaterial.specular: PySide6.QtGui.QColor#

Holds the current specular color.

Access functions:
property PᅟySide6.Qt3DExtras.Qt3DExtras.QDiffuseMapMaterial.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, 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.
