Source objects

Source objects

Here is a list of types of ray sources supported by the raytracer. Sources require following parameters:

• type: Type string. See below.
• name: Unique name
• rays: Number of rays to emit
• wavelengths: Array of wavelengths in [nm].
• intensities: Array of intensities for the corresponding wavelength [W/nm].
• location: Array(3) Location of the source object. (Volume sources do not require this)
• insideOf: ID of the object the source is inside of.

List of types of sources:

• SurfaceNormal
• IsotropicPoint
• LambertianPoint
• DirectionalPoint
• IsotropicVolume
• IsotropicConicalPointSource

Detailed desciptions

SurfaceNormal

Emits rays directly at surface normal direction from the source. Rays are directed outwards of the object.

Required:

• attachedTo: Number 0-> indicating the surface the source is attached to.

---

IsotropicConicalPointSource

Emits rays from a point isotropically inside a conical sector. The opening angle can be defined.

Required:

• direction: array(3) Indicates the direction the cone opens.
• coneHalfAngle: Number(degrees) Opening angle of the cone.
