Detailed Description

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.

Property Documentation

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.

Access functions:

QVariant ambientOcclusion() const
void setAmbientOcclusion(const QVariant &ambientOcclusion)

Notifier signal:

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".

Access functions:

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

Notifier signal:

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.

Access functions:

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

Notifier signal:

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.

Access functions:

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

Notifier signal:

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.

Access functions:

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

Notifier signal:

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.

Access functions:

float textureScale() const
void setTextureScale(float textureScale)

Notifier signal:

void textureScaleChanged(float textureScale)

Member Function Documentation

QMetalRoughMaterial::QMetalRoughMaterial(Qt3DCore::QNode *parent = nullptr)

Constructs a new QMetalRoughMaterial instance with parent object parent.

[virtual] QMetalRoughMaterial::~QMetalRoughMaterial()

Destroys the QMetalRoughMaterial instance.
