QNormalDiffuseMapMaterial¶

The QNormalDiffuseMapMaterial provides a default implementation of the phong lighting and bump effect where the diffuse light component is read from a texture map 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.QNormalDiffuseMapMaterial([parent=None])¶

param parent:

PySide2.Qt3DCore.Qt3DCore.QNode

Constructs a new QNormalDiffuseMapMaterial instance with parent object parent .

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseMapMaterial.ambient()¶

Return type:: PySide2.QtGui.QColor

Holds the current ambient color.

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseMapMaterial.ambientChanged(ambient)¶

Parameters:: ambient – PySide2.QtGui.QColor

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseMapMaterial.diffuse()¶

Return type:: PySide2.Qt3DRender.Qt3DRender.QAbstractTexture

Holds the current diffuse map texture.

By default, the diffuse texture has these properties:

Linear minification and magnification filters
Linear mipmap with mipmapping enabled
Repeat wrap modeM
Maximum anisotropy of 16.0

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseMapMaterial.diffuseChanged(diffuse)¶

Parameters:: diffuse – PySide2.Qt3DRender.Qt3DRender.QAbstractTexture

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseMapMaterial.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.QNormalDiffuseMapMaterial.normalChanged(normal)¶

Parameters:: normal – PySide2.Qt3DRender.Qt3DRender.QAbstractTexture

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseMapMaterial.setAmbient(ambient)¶

Parameters:: ambient – PySide2.QtGui.QColor

Holds the current ambient color.

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseMapMaterial.setDiffuse(diffuse)¶

Parameters:: diffuse – PySide2.Qt3DRender.Qt3DRender.QAbstractTexture

Holds the current diffuse map texture.

By default, the diffuse texture has these properties:

Linear minification and magnification filters
Linear mipmap with mipmapping enabled
Repeat wrap modeM
Maximum anisotropy of 16.0

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseMapMaterial.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.QNormalDiffuseMapMaterial.setShininess(shininess)¶

Parameters:: shininess – float

Holds the current shininess as a float value.

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseMapMaterial.setSpecular(specular)¶

Parameters:: specular – PySide2.QtGui.QColor

Holds the current specular color.

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseMapMaterial.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.QNormalDiffuseMapMaterial.shininessChanged(shininess)¶

Parameters:: shininess – float

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseMapMaterial.specular()¶

Return type:: PySide2.QtGui.QColor

Holds the current specular color.

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseMapMaterial.specularChanged(specular)¶

Parameters:: specular – PySide2.QtGui.QColor

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseMapMaterial.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.

PySide2.Qt3DExtras.Qt3DExtras.QNormalDiffuseMapMaterial.textureScaleChanged(textureScale)¶
