PySide6.Qt3DExtras.Qt3DExtras.QNormalDiffuseSpecularMapMaterial

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:
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:
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:
property shininessᅟ: float

Holds the current shininess as a float value.

Access functions:
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:
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.
