Assignment – Light sources, shadows


The aim of the assignment is to link your theoretical knowledge with the tools of the 3D modelling software Blender. The assignment is the result of the activity on the online lesson.
The first topic covers light sources and shadows.

Modelling in Blender

Create a simple scene with several objects (e.g. sphere, torus, teapot, bunny etc.) and a plane, which serves as an underlay to these objects.

Each object has its own base color (set in Materials tab). The objects do not have to be textured.

Document structure

You will create a (.pdf) file with several dozens of figures. Each figure is described by few sentences describing the settings of a certain parameter, property or a object. Also, explain and show (if possible) the main principle, how the parameters are computed, or how they affect the scene.

Please, use separate figures (rendered images) and descriptions for each change of the settings of the scene.



Now the scene contains only one spotlight with the apex placed above the cube. The beam is characterized by the circular cone, with following parameters:

What has to be included and discussed

The front page – includes the name of the project, your name, study program and academic year.
Types of the lamps (light sources)

Shadows – describe the parameters of the shadows in the render settings, discuss how the parameters affect the softness of a shadow
Ambient occlusion – show and briefly describe how the parameters affect the lighting in the scene
Bloom – show and briefly describe how the parameters affect the lighting in the scene. To achieve this create a scene with several objects, where one of them is blooming
Several lamps in the scene – use different settings for each lamp and shadow, show and explain, how these setting affects the scene. You may follow the three point lighting tutorial from the lesson
