Sapphire Plug-ins for Autodesk: LaserBeam

LaserBeam

Simulates the beam from a science fiction style laser blaster. The beam moves over a number of frames from a source point to a target point. A perspective effect may also be added.

Inputs:

Back: Optional. The clip to use as background.

Parameters:

Load Preset: Push-button .
Brings up the Preset Browser to browse all available presets for this effect.

Save Preset: Push-button .
Brings up the Preset Save dialog to save a preset for this effect.

Start: X & Y,   Default: [-0.444 -0.287], Range: any.
Staring point for the beam. This parameter can be adjusted using the Start Widget.

Stop: X & Y,   Default: [0.111 0.33], Range: any.
Target point for the beam. This parameter can be adjusted using the Stop Widget.

Shift: X & Y,   Default: [0 0], Range: any.
Moves the Start and Stop points, shifting the whole beam to a different location. This parameter can be adjusted using the Shift Widget.

Laser Shape: Popup menu,  Default: Forward .
The shape of the drawn segment of the beam.
Smooth: The segment is drawn with a circular profile.
Spear: The segment is drawn as a symmetrical shape with sharpened ends.
Forward: The segment is drawn as an asymmetrical shape with the leading end wider than the trailing end.
Backward: The segment is drawn as an asymmetrical shape with the trailing end wider than the leading end.

Position: Default: 0.5, Range: 0 to 1.
Where the drawn beam segment should appear along the beam trajectory. At 0, the drawn beam segment will not yet have emerged from the source point. NOTE: nothing will be drawn at this point! At 1, the drawn beam segment will have gone inside the target point. NOTE: again, nothing will be drawn. At values in between, the beam segment will appear along the beam trajectory. The beam position may be controlled manually by key framing this control, or its position can be controlled by the frame number using the time controls.

Length: Default: 0.5, Range: 0.001 to 5.
Length of the drawn beam segment.

Width: Default: 0.01, Range: 0.001 to 0.5.
Width of the drawn beam segment.

Perspective: Default: 0, Range: -1 to 1.
The strength of the persepctive effect. At zero, there is no effect. Positive values move the bolt nearer to the target than it otherwise would be at a given beam position (or time), while negative values move it nearer to the source.

Softness: Default: 1, Range: 0 to 2.
Softness of the texturing in the beam.

Smooth: Default: 0, Range: 0 to 1.
Overall smoothing applied to the beam segment.

Combine: Popup menu,  Default: Screen .
Determines how the beam image is combined with the background.
Screen: blends the beam with the background, which can help prevent overly bright results.
Add: causes the beam image to be added to the background.
Beam Only: shows the beam over a transparent black background.

Core Color: Default rgb: [1 1 0].
Color at the center of the beam.

Edge Color: Default rgb: [1 0 0].
Color at the edge of the beam.

Color Balance: Default: 0.5, Range: 0 to 1.
Adjusts the balance between the core and edge colors.

Brightness: Default: 1, Range: 0 to 10.
Brightness of the beam.

Fade Back: Default: 0, Range: 0 or greater.
Fades out the brightness of the back half of the beam. Setting this to 1 will fade to black at the very back of the beam. Higher values will fade out more quickly.

Fade Front: Default: 0, Range: 0 or greater.
Fades out the brightness of the front half of the beam. Setting this to 1 will fade to black at the very front of the beam. Higher values will fade out more quickly.

Breakup: Default: 0.05, Range: 0 to 1.
As this increases, the drawn beam segment become more and more ragged.

Params2:

Start Time: Default: 0, Range: 0 to 600.
If using the time mode of operation, this is the time at which the beam will start out from the source.

Duration: Default: 10, Range: 0 to 500.
If using the time mode of operation, this is the duration of flight of the laser beam. After start time + duration the beam will disappear into the target.

Use Time: Check-box,  Default: off.
Control the motion of the beam segment automatically with frame number rather than manually with the position control.

Shutter Angle: Default: 0, Range: 0 or greater.
Adjusts the shutter angle for motion blur. This controls the amount of time that the simulated shutter is open, and thus the overall amount of motion blur. A value of 0 disables motion blur. A value of 360 degrees will blur over an entire frame, which is the maximum amount of motion blur possible with a real camera. Values above 360 degrees will produce unrealistic results in which the motion of adjacent frames overlaps.

Samples: Integer,  Default: 16, Range: 2 or greater.
Controls the number of individual renders that are averaged together when applying motion blur. Increasing the number of samples will give smoother results, but will also increase render times. If too few samples are used, there can be visible aliasing or ghosting artifacts. Faster motion will require more samples to avoid artifacts.

Atmosphere Parameters:

Atmosphere Amp: Default: 0, Range: 0 or greater.
Atmosphere gives the effect of the laser shining through a dusty atmosphere and picking up light or getting shadowed. This parameter adjusts the amount, or amplitude, of the atmospheric effect. Zero gives a smooth beam, higher values give more dusty look.

Atmosphere Freq: Default: 4, Range: 0.1 or greater.
Controls the spatial frequency of the atmospheric noise. Turn this up higher to get finer details, turn down for broader overall variation.

Atmosphere Detail: Default: 0.8, Range: 0 to 1.
Controls the amount of fine detail in the atmosphere simulation. Decrease to get smoother atmosphere, increase for a more crunchy or grainy look.

Atmosphere Seed: Default: 0.123, Range: 0 or greater.
Used to initialize the random number generator for the atmospheric noise. The actual seed value is not significant, but different seeds give different results and the same value should give a repeatable result.

Atmosphere Speed: Default: 1, Range: any.
The cloudy noise in the atmosphere evolves over time like real dust clouds; this parameter controls how fast the cloud pattern changes over time. Set to zero for a static pattern.

Params3:

Mocha: Default: 0, Range: 0 or greater, Shared .
Brings up the Mocha window for tracking footage and generating masks.

Blur Mocha: Default: 0, Range: 0 or greater, Shared .
Blurs the Mocha Mask by this amount before using. This can be used to soften the edges or quantization artifacts of the mask, and smooth out the time displacements.

Mocha Opacity: Default: 1, Range: 0 to 1, Shared .
Controls the strength of the Mocha mask. Lower values reduce the intensity of the effect.

Invert Mocha: Check-box,  Default: off, Shared .
If enabled, the black and white of the Mocha Mask are inverted before applying the effect.

Show Mocha Only: Check-box,  Default: off, Shared .
Bypass the effect and show the Mocha Mask itself.

Bypass Mocha: Check-box,  Default: off, Shared .
Ignore the Mocha Mask and apply the effect to the entire source clip.
