详细描述

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.

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.

ambient : QColor

Holds the current ambient color.

访问函数:

QColor ambient () const
void setAmbient (const QColor & ambient )

通知程序信号:

void ambientChanged (const QColor & ambient )

diffuse : 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

访问函数:

Qt3DRender::QAbstractTexture * diffuse () const
void setDiffuse (Qt3DRender::QAbstractTexture * diffuse )

通知程序信号:

void diffuseChanged (Qt3DRender::QAbstractTexture * diffuse )

normal : 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

访问函数:

Qt3DRender::QAbstractTexture * normal () const
void setNormal (Qt3DRender::QAbstractTexture * normal )

通知程序信号:

void normalChanged (Qt3DRender::QAbstractTexture * normal )

shininess : float

Holds the current shininess as a float value.

访问函数:

float shininess () const
void setShininess (float shininess )

通知程序信号:

void shininessChanged (float shininess )

specular : QColor

Holds the current specular color.

访问函数:

QColor specular () const
void setSpecular (const QColor & specular )

通知程序信号:

textureScale : float

Holds the current texture scale. It is applied as a multiplier to texture coordinates at render time. Defaults to 1.0.

访问函数:

float textureScale () const
void setTextureScale (float textureScale )

通知程序信号:

void textureScaleChanged (float textureScale )
