NormalDiffuseMapMaterial QML Type

The NormalDiffuseMapMaterial provides a default implementation of the phong lighting and bump effect where the diffuse light component is read from a texture map and the normals of the mesh being rendered from a normal texture map. More...

Import Statement: import Qt3D.Extras 2.0
Since: Qt 5.7

Properties

Detailed Description

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.

Property Documentation

ambient : color

Holds the current ambient color.

diffuse : TextureImage

Holds the current diffuse map texture.

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

normal : TextureImage

Holds the current normal map texture.

By default, the normal texture has the following properties:

  • Linear minification and magnification filters
  • Repeat wrap mode
  • Maximum anisotropy of 16.0

shininess : real

Holds the current shininess.

specular : color

Holds the current specular color.

textureScale : real

Holds the current texture scale. It is applied as a multiplier to texture coordinates at render time. Defaults to 1.0.
