The phong 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:
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.
Indicates if the alpha information coming from the diffuse property will be taken into account during rendering. Defaults to false.
访问函数:
bool | isAlphaBlendingEnabled () const |
void | setAlphaBlendingEnabled (bool enabled ) |
通知程序信号:
void | alphaBlendingEnabledChanged (bool enabled ) |
Holds the ambient color that is emitted by an object without any other light source.
访问函数:
QColor | ambient () const |
void | setAmbient (const QColor & ambient ) |
通知程序信号:
void | ambientChanged (const QColor & ambient ) |
Holds the diffuse color of the material that is emitted for rough surface reflections with the lights. This can be either a plain color value or a texture.
访问函数:
QVariant | diffuse () const |
void | setDiffuse (const QVariant & diffuse ) |
通知程序信号:
void | diffuseChanged (const QVariant & diffuse ) |
Holds the current normal map texture of the material. This can only be a texture, otherwise it is ignored. By default this map is not set.
访问函数:
QVariant | normal () const |
void | setNormal (const QVariant & normal ) |
通知程序信号:
void | normalChanged (const QVariant & normal ) |
Holds the shininess exponent. Higher values of shininess result in a smaller and brighter highlight.
Defaults to 150.0.
访问函数:
float | shininess () const |
void | setShininess (float shininess ) |
通知程序信号:
void | shininessChanged (float shininess ) |
Holds the specular color of the material that is emitted for shiny surface reflections with the lights. This can be either a plain color value or a texture.
访问函数:
QVariant | specular () const |
void | setSpecular (const QVariant & specular ) |
通知程序信号:
void | specularChanged (const QVariant & specular ) |
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.
访问函数:
float | textureScale () const |
void | setTextureScale (float textureScale ) |
通知程序信号:
void | textureScaleChanged (float textureScale ) |
