详细描述

The QDiffuseSpecularMaterial class provides a default implementation of the phong lighting effect.

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.

特性文档编制

alphaBlending : bool

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 )

ambient : QColor

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 )

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.

访问函数：

QVariant	diffuse () const
void	setDiffuse (const QVariant & diffuse )

通知程序信号：

void	diffuseChanged (const QVariant & 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.

访问函数：

QVariant	normal () const
void	setNormal (const QVariant & normal )

通知程序信号：

void	normalChanged (const QVariant & normal )

shininess : float

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 )

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.

访问函数：

QVariant	specular () const
void	setSpecular (const QVariant & specular )

通知程序信号：

void	specularChanged (const QVariant & 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.

访问函数：

float	textureScale () const
void	setTextureScale (float textureScale )

通知程序信号：

void	textureScaleChanged (float textureScale )
