Assignment 4 - Adding Lighting

Help:

To place an object:

Open "Create" tab on the left pane.
Select an object from drop-down menu, a sphere, a cone, or a cylinder.
Set object's color from "Object color" color-picker. Note that, if Material's Diffuse is set to be global, then this color have no effect. In order to this color to be rendered, then Material's diffuse must be turned off.
Set size (scale) of object. In 3D: X, Y and Z scales.
Set position (translate) of object. Z translation can be set via slider. X and Y translation is set automatically when mouse-clicking on canvas.
Set orientation (rotate) of object. In 3D: X, Y and Z rotations. This is object's rotation, not world rotation, not camera rotation.
Click on canvas to place the chosen object.

To select an object:

Open "Select & Modify" tab on the left pane.
In the table, select an object to be selected, by clicking on the radio-button. Scroll the table if necessary.
After selecting the object, it can be deleted, or to be modified.
To delete the selected object, click on "Delete selected object" button.
To modify the selected object, slide the sliders: scale, translate, rotate.

Moving Lights:

There are two moving lights.
Light #1 is moving in circular track around the canvas.
Light #2 is moving in rectangular track around the canvas.
Each light's ambient, diffuse, and specular can be changed via color-picker.
Z position of each light can be changed via spinner.
Which light is on or off can be selected via radio-button. Either light #1 only, light #2 only, both lights, or none. When none light is selected, then a dark ambient light make the object(s) still visible.

Material:

Material's ambient, diffuse, specular can be selected via color-picker.
Material's diffuse determine the object's color.
If material's diffuse is global, then all objects have the same color.
In order for each object to have their own color, then global diffuse must be turned off via the check-box.
Material's shininess can be set via the slider.
