Electron Tomography Toolbox for Amira

Description:

The RayTracer module is a tool for generating photorealistic images of a 3D scene. The module allows you to provide any object in the scene with different features. These features are on the one hand illumination factor for ambient illumination, diffuse illumination and phong illumination. On the other hand the reflexivity and the refraction factor of the object as well as textures and bumps can be added. Furthermore it is possible to add 1 ore more light sources to the scene to visualize shadows. Light sources can either be point lights, which emits light rays in every direction or spot lights, which emits light rays only within a defined angle in one direction.
Press the Apply button to start the computation.

Ports:

This slider defines the light intensity which reaches every Object (even when the Object is in shade).

This slider defines the refraction index of the surrounding volume of a scene.

These number fields define the x and y dimensions of the output image.
Tip: the output image look better when the x and y values are equal.

This slider defines the maximum number of secondary rays (reflected and refracted rays).
Tip: if an object should be transparent, make sure that the Number of Reflections is at least 2.

This file chooser defines the path and the filename of the output file.
File Formats: every 2D image format Amira can write.

With these 2 buttons light source can be added or removed.
There has to be at least 1 light source (1 spot light by default).

With this drop down menu one particular light source can be chosen.

This radio box defines the Type of the light source.
The port is only visible when a light from the port Light is chosen.

When this checkbox is checked the light source dragger will be visible in the scene. The form of the Dragger depends on the type of the light source.
The port is only visible when a light from the port Light is chosen.

These number fields define the location of the light in the scene. The values can either be set by typing the x, y and z values or via the dragger.
The port is only visible when a light from the port Light is chosen.

These number fields define the direction of the light.
The values can either be set by typing the x, y and z values or via the dragger.
The port is only visible when a light from the port Light is chosen and the port Type is set to Spotlight.

This number field defines the angle of the light cone spotlight in degree.
The port is only visible when a light from the port Light is chosen and the port Type is set to Spotlight.

When this button is pressed the objects information will be updated.

With this drop down menu one particular object can be chosen.

This slider defines the diffuse light intensity of an object.
The port is only visible when an object from the port Objects is chosen.

This slider defines the transparency factor of the object.
The port is only visible when an object from the port Objects is chosen.

This slider defines the refraction index of the object.
The port is only visible when an object from the port Objects is chosen.

This slider defines the reflectivity of an object.
0 = no reflection
1 = perfect mirror
The port is only visible when an object from the port Objects is chosen.

This slider defines the intensity of highlights (specular reflection).
The port is only visible when an object from the port Objects is chosen.

This slider defines the roughness of an object. The higher this factor the smaller and brighter are the highlights.
The port is only visible when an object from the port Objects is chosen.

This file chooser defines the path and the filename of a texture file.
File Formats: every 2D image format Amira can read.
The port is only visible when an object from the port Objects is chosen.

This file chooser defines the path and the filename of a bump map file.
File Formats: every 2D image format Amira can read.
These images should be grayscale images.
The port is only visible when an object from the port Objects is chosen.
