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.

class PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseSpecularMapMaterial([parent=None])

Constructs a new QNormalDiffuseSpecularMapMaterial instance with parent object parent .

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseSpecularMapMaterial.ambient()
Return type:

PySide2.QtGui.QColor

Holds the current ambient color.

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseSpecularMapMaterial.ambientChanged(ambient)
Parameters:

ambient – PySide2.QtGui.QColor

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseSpecularMapMaterial.diffuse()
Return type:

PySide2.Qt3DRender.Qt3DRender.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

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseSpecularMapMaterial.diffuseChanged(diffuse)
Parameters:

diffuse – PySide2.Qt3DRender.Qt3DRender.QAbstractTexture

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseSpecularMapMaterial.normal()
Return type:

PySide2.Qt3DRender.Qt3DRender.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

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseSpecularMapMaterial.normalChanged(normal)
Parameters:

normal – PySide2.Qt3DRender.Qt3DRender.QAbstractTexture

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseSpecularMapMaterial.setAmbient(ambient)
Parameters:

ambient – PySide2.QtGui.QColor

Holds the current ambient color.

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseSpecularMapMaterial.setDiffuse(diffuse)
Parameters:

diffuse – PySide2.Qt3DRender.Qt3DRender.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

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseSpecularMapMaterial.setNormal(normal)
Parameters:

normal – PySide2.Qt3DRender.Qt3DRender.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

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseSpecularMapMaterial.setShininess(shininess)
Parameters:

shininess – float

Holds the current shininess as a float value.

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseSpecularMapMaterial.setSpecular(specular)
Parameters:

specular – PySide2.Qt3DRender.Qt3DRender.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

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseSpecularMapMaterial.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.

Return type:

float

Holds the current shininess as a float value.

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseSpecularMapMaterial.shininessChanged(shininess)
Parameters:

shininess – float

Return type:

PySide2.Qt3DRender.Qt3DRender.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

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseSpecularMapMaterial.specularChanged(specular)
Parameters:
