详细描述

This material uses an effect with a single render pass approach and performs per fragment lighting. Techniques are provided for OpenGL 3 and OpenGL ES 3.

ambientOcclusion : QVariant

Holds the current ambient occlusion 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	ambientOcclusion () const
void	setAmbientOcclusion (const QVariant & ambientOcclusion )

通知程序信号：

void	ambientOcclusionChanged (const QVariant & ambientOcclusion )

baseColor : QVariant

Holds the current base color of the material. This can be either a plain color value or a texture. By default the value of this property is "grey".

访问函数：

QVariant	baseColor () const
void	setBaseColor (const QVariant & baseColor )

通知程序信号：

void	baseColorChanged (const QVariant & baseColor )

metalness : QVariant

Holds the current metalness level of the material, as a value between 0 (purely dielectric, the default) and 1 (purely metallic). This can be either a plain uniform value or a texture. By default the value of this property is 0.

访问函数：

QVariant	metalness () const
void	setMetalness (const QVariant & metalness )

通知程序信号：

void	metalnessChanged (const QVariant & metalness )

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 )

roughness : QVariant

Holds the current roughness level of the material. This can be either a plain uniform value or a texture. By default the value of this property is 0.

访问函数：

QVariant	roughness () const
void	setRoughness (const QVariant & roughness )

通知程序信号：

void	roughnessChanged (const QVariant & roughness )

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 )
