Materials

class Material()

Abstract class for materials

Constructor.

Material.Material

Constructor.

Material.isMaterial

type: boolean

Says that the object inherits from Material

Material.isReflecting

Says whether the material is reflecting Default is false.

Material.isTransparent

Says whether the material is transparent Default is false.

Material.lights

The light eventually affecting the material. If lights is not set up when the solid carrying the material is added to the scene, then lights is set up to the list of lights in the scene.

Material.reflectivity

type: Color

Reflectivity of the material. Each channel (red, blue, green), interpreted as number between 0 and 1, is the reflectivity coefficient of the corresponding color (0 = no reflectivity, 1 = all light is reflected).

Material.usesLight

Says whether the material reacts to (certain) lights in the scene. Default is false.

Material.usesNormal

Says whether the material requires the normal to the shape for its computation. Default is true.

Material.usesUVMap

Says whether the material requires a UV map on the shape for its computation. Default is false.

Material.glslInstance()

Compile all the function directly related to the object (e.g. render).

Returns:

string –

Material.glslRender()

Return the chunk of GLSL code used to compute the color of the material at the given point The render function on the GLSL side should have one of the following signatures - vec4 {{name}}_render(ExtVector v) - vec4 {{name}}_render(ExtVector v, RelVector normal) - vec4 {{name}}_render(ExtVector v, vec2 uv) - vec4 {{name}}_render(ExtVector v, RelVector normal, vec2 uv) The exact signature depends on whether the material requires a normal or UV coordinates. Here v is the vector obtained when we hit the shape. It should return the color as a vec3 of the material at the given point, without taking into account reflections.

Returns:

string –

class PTMaterial()

Abstract class for materials for path tracer

Constructor.

PTMaterial.PTMaterial

Constructor.

PTMaterial.isPTMaterial

type: boolean

Says that the object inherits from PTMaterial

PTMaterial.usesNormal

Says whether the material requires the normal to the shape for its computation. Default is true.

PTMaterial.usesUVMap

Says whether the material requires a UV map on the shape for its computation. Default is false.

PTMaterial.glslInstance()
