Overview

The basic material definition to NinevehGL.

The NGLMaterial is an user friendly API to deal with OpenGL’s fragment shaders. Each material’s property represents a specific predefined behavior in the fragment shaders. Obviously you can define and construct custom shaders. The materials is just a simple way to deal with the most used and populars behaviors in the fragment shaders.

The actual version of NGLMaterial can deal with:

  • Alpha and transparency;
  • Ambient color and texture;
  • Diffuse color and texture;
  • Emissive color and texture;
  • Shininess;
  • Specular component;
  • Bump effect;
  • Reflection map.

Even using the materials (that is the default immutable NinevehGL’s behavior) you can create your shaders. The both shaders will be merged to form a new shader with unique behavior.

Tasks

  •   name

    The item’s name. This can also be used by identify this object.

         property
  •   identifier

    The identifier of this object.

         property
  •   alpha

    The alpha component in a range of (0.0, 1.0). The 0.0 means a fully transparent material and 1.0 indicates a fully opaque material.

         property
  •   ambientColor

    The material’s ambient color reflection. This property is taken by the shaders as reflection an ambient multi directional white light placed at the infinity, that means it will cover all the surface with the same color and intensity.

         property
  •   diffuseColor

    The material’s diffuse color reflection. This property suffers influence from the scene lights.

         property
  •   emissiveColor

    The material’s emissive color amount. This property simulates an emission of light from this material by adding an uniform glow effect on it.

         property
  •   specularColor

    The material’s specular color reflection. This property simulates the specular color and intensity from lights on this material.

         property
  •   shininess

    The shininess specifies the specular exponent, also known as glossiness. This defines the focus of the specular highlight. The value lies in a range of (0.0, 1000.0), the high exponent results in a tight reflective light, a concentrated highlight, low exponent results in large and spread reflection.

         property
  •   reflectiveLevel

    The reflective level attenuates the reflective map. The value lies in a range of (0.0, 1.0), where 0 means no reflection and 1 means full reflection. The default value is 0.5.

         property
  •   refraction

    The refraction property indicates the index of refraction to this object.

         property
  •   alphaMap

    The alpha defined by a texture map. To achieve more precision, the map should be constructed with grey scale only, where a full white represents the fully opaque areas and full black represents the fully transparent areas.

         property
  •   ambientMap

    Defines the material’s ambient color reflection by a texture map.

         property
  •   diffuseMap

    Defines the material’s diffuse color reflection by a texture map.

         property
  •   emissiveMap

  •   specularMap

    Defines the material’s specular color reflection by a texture map.

         property
  •   shininessMap

    Defines the shininess by a texture map. To achieve more precision, the map should be constructed with grey scale only, where the full white represents the value of 1000 and full black represents the 0.

         property
  •   bumpMap

    Defines the bump effect by a texture map. By default the bump map should be constructed with a normal map with the tangent space colors.

         property
  •   reflectiveMap

    Defines the reflection of the material by a texture map. All the reflection maps will be treated as an enviroment spherical map.

         property
