详细描述

This class is deprecated; use Qt3DExtras::QDiffuseSpecularMaterial 代替。

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.

特性文档编制

ambient : QColor

Holds the current ambient color.

访问函数：

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

通知程序信号：

void	ambientChanged (const QColor & ambient )

diffuse : Qt3DRender::QAbstractTexture *

Holds the current texture used as the diffuse map.

By default, the diffuse texture has the following properties:

• Linear minification and magnification filters
• Linear mipmap with mipmapping enabled
• Repeat wrap mode
• 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 )

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：

void	specularChanged (const QColor & 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.

void	setTextureScale (float textureScale )
