Detailed Description▲
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:
-
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.
Property Documentation▲
alphaBlending : bool▲
Indicates if the alpha information coming from the diffuse property will be taken into account during rendering. Defaults to false.
Access functions:
-
bool isAlphaBlendingEnabled() const
-
void setAlphaBlendingEnabled(bool enabled)
Notifier signal:
-
void alphaBlendingEnabledChanged(bool enabled)
ambient : QColor▲
Holds the ambient color that is emitted by an object without any other light source.
Access functions:
-
ambient() const
-
void setAmbient(const &ambient)
Notifier signal:
-
void ambientChanged(const &ambient)
diffuse : QVariant▲
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.
Access functions:
-
diffuse() const
-
void setDiffuse(const &diffuse)
Notifier signal:
-
void diffuseChanged(const &diffuse)
normal : QVariant▲
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.
Access functions:
-
normal() const
-
void setNormal(const &normal)
Notifier signal:
-
void normalChanged(const &normal)
shininess : float▲
Holds the shininess exponent. Higher values of shininess result in a smaller and brighter highlight.
Defaults to 150.0.
Access functions:
-
float shininess() const
-
void setShininess(float shininess)
Notifier signal:
-
void shininessChanged(float shininess)
specular : QVariant▲
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.
Access functions:
-
specular() const
-
void setSpecular(const &specular)
Notifier signal:
-
void specularChanged(const &specular)
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, 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.
Access functions:
-
float textureScale() const
-
void setTextureScale(float textureScale)
Notifier signal:
-
void textureScaleChanged(float textureScale)
