Point Light [3PL] | |
|
|
A Point Light is a light source with a clear position in space that emits light in all directions. A lightbulb is a point light, as is the sun, although light from the sun can appear to be ambient due to scattering from the atmosphere. This light shows an onscreen widget, although only the position of the widget affects the light. Since the light is a 360 degree source the rotation of the widget has no meaning. Unlike both ambient and directional lights, a point light may falloff with distance. |

Point Light Controls Tab
When the Enabled checkbox is selected, the directional light affects the scene. Clear the checkbox to turn off the light.
Use this standard Color control to set the color of the light.
Use this slider to set the Intensity of the point light.
A point light defaults to No Falloff, meaning that its light has equal intensity at all points in the scene. To cause the intensity to falloff with distance, set the Decay Type either to Linear or Quadratic modes.
3D Transformation Tab
On Screen : Transformation Widget
Most of the controls in this tab are represented in the display view by a Transformation Widget with modes for transformation, rotation and scaling. To change the mode of the widget, select one of the three buttons in the toolbar along the side of the view, or press the `q' key for translation mode, `w' for rotation and `e' for scaling. In all three modes, individual axes of the control may be dragged to affect just that axis, or the center of the control may be dragged to affect all three axes. Note: In order to scale in a single dimension, the Lock X/Y/Z Scale checkbox must be unchecked.
These controls can be used to position the 3D element.
Use these buttons to select which order is used to apply the Rotation along each axis of the object. For example, XYZ would apply the rotation to the X axis first, followed by the Y axis and then followed by the Z axis.
Use these control to rotate the object around its pivot point. If the Use Target checkbox is selected then the rotation is relative to the position of the target, otherwise the global axis is used.
A Pivot point is the point around which an object rotates. Normally, an object will rotate around its own center, which is considered to be a pivot of 0,0,0. These controls can be used to offset the pivot from the center.
If the Lock X/Y/Z checkbox is checked, a single Scale slider will be shown. This adjusts the overall size of the object. If the Lock checkbox is unchecked, individual X, Y and Z sliders will be displayed to allow scaling in any dimension. Note: If the Lock checkbox is checked, scaling of individual dimensions is not possible, even when dragging specific axes of the Transformation Widget in scale mode.
Selecting the Use Target checkbox enables a set of controls for positioning an XYZ target. When target is enabled, the object will always rotate to face the target. The rotation of the object becomes relative to the target.
