Global FX are post production FX modules that can modify the
image created by the renderer - the only difference between
Global FX and standard post production techniques is that the
FX modules know about the Imagine rendering world (frame numbers,
object positions, object geometry, etc.) and can use this information
to direct the post production.

|
Haze.
This effect will key off of a specific colour in an image, and
blend that colour outward from wherever is is found. Bright objects
can be given an apparent glow or halo by telling the effect to
look for the colour of the bright object.
This effect is animatable: Something can flare up and/or down
during an animation, over any number of frames. |
|
FadeToColour
This effect will fade an image in/out to any specified colour,
over any number of frames. |
|
Toon
This effect will take a rendered image, and turn it into something
resembling a cartoon.
Like all effects, this can be animated over time. |
|
Negative
This effect will turn an image, or animation, into a negative
(reverse image).
Like all effects, this can be animated over time. |
|
Solarize
Solarization is another photography "trick". The idea in a black
and white image would be to leave dark areas dark, push mid-tones
to white and push light tones to white.
This effect does something similar, but in colour and results
in a creepy, psychedelic look. A black and white solarization
can be achieved by combining the RGBMix and Solarize effects.
Like all effects, this can be animated over time. |
|
RGB mixer
This effect allows the remapping all of the colors in an image.
By remapping the colors, a colour image can be converted into
a gray scale (not only a gray scale, but a TV ballanced black
and white image), change the intensity of a particular colour,
or create a false colour image.
Like all effects, this can be animated over time. |
|
Melt
This effect will take an animation, perform a "liquidy" effect,
and slide the image off the screen.
|
|
Contrast
This effect will alter the contrast of a final image.
Like all effects, this can be animated over time. |
|
All the above effects are currently available in versions for
the 68k and PowerPC processors.
Cepia, LensFlare, and NewLensFlare are only available for the
68k. (PowerPC versions available soon)
