Name Version Type By
Shader Toolkit 0.96 Definition Simon Scheckel, with edits by AFRLme

This script offers some easy functions to use shader power. It ranges from blur, noise, saturation, contrast, lightness, colorize to some simple camera controls. Visionaire Studio 5.x is required to run this script.

Quick note: The script on here may be outdated, please download the latest version for 5.x from the resources section at the bottom of the page.

Instructions

1. Add the main script to the Visionaire Studio Script Editor & set the script as a definition script.
2. Call the functions you need.

Shader Toolkit Functions

Function Name Description
shaderAddEffect() Add various dynamic pre-made warp effects to the screen.
shaderBlur() Blur/Focus the screen over x amount of milliseconds.
shaderColorize() Tint all the graphics on the screen a specific color over x amount of milliseconds.
shaderContrast() Set the global contrast level of the screen over x amount of milliseconds.
shaderFollowCharacter() Softly follow the linked character around the screen.
shaderGlow() Create a glow effect on light/saturated scene objects (automatically selected) over x amount of milliseconds.
shaderHue() Adjust the hue level of the screen over x amount of milliseconds.
shaderLightness() Adjust the lightness of the screen over x amount of milliseconds.
shaderNoise() Apply noise effect to the screen over x amount of milliseconds.
shaderPan() Pan the camera on the x or y axis over x amount of milliseconds.
shaderRotate() Rotate the screen over x amount of milliseconds.
shaderSaturation() Adjust saturation value of the screen over x amount of milliseconds.
shaderViewport() Pan, zoom & rotate the camera over x amount of milliseconds.
shaderZoom() Zoom the camera over x amount of milliseconds.
shaderZoomCharacter() Zoom camera into or out of linked characters position over x amount of milliseconds.
shaderZoomObject() Zoom camera into or out of linked objects location over x amount of milliseconds.


Examples

shaderZoomCharacter("", 1.2, 3000, easeBackOut) -- Zoom 1.2x on current character in 3s with one bounce
shaderZoomObject(getObject("Objects[pole]"), 1.4, 3000, easeBounceOut)
shaderFollowCharacter("Heinz", 2, 3000, easeQuintOut) -- Follow character Heinz with a slow camera
shaderViewport(2, 300, 200, 1.41, 3000, easeBounceInOut) -- advanced zooming with rotating

shaderNoise(1, -0.1, 3000) -- activate noise in 3s with a soft black grain
shaderBlur(1, 3000) -- activate blur in 3s
shaderSaturation(0, 3000) -- desaturate image in 3s
shaderLightness(-0.5, 3000) -- darken image in 3s
shaderContrast(2, 3000) -- double contrast
shaderHue(0.5, 2000) -- turn hue wheel, red->green
shaderColorize(0, 1, 3000) -- colorize with red


Reset Values

shaderViewport(1, 0, 0, 0, 1000, easeQuintOut)

-- Shader Toolkit Hue, Saturation, Luminance, Blur, Noise, Camera Control, Bloom, Random Effects
-- (c) 2015 Simon Scheckel, Visionaire Studio Engine - with edits by AFRLme
-- Version 0.96
-- updated 29/09/2014 for 4.1
-- added some save functionality 9/10
-- bugfix version 16/10
-- update 10/6/15 radial glow, use per object matrices
-- update 3/2/16 cross platform shaders requires 4.3
-- update 28/9/18 lua 5.3
--
-- Matrix functions from https://github.com/davidm/lua-matrix/blob/master/lua/matrix.lua
-- Developers:    Michael Lutz (chillcode) - original author    David Manura http://lua-users.org/wiki/DavidManura
--
-- Usage:
--
-- all factors like zoom, scale are normally 1 to have no change
-- delay in ms
-- hue in 0-1 (0 = red, 0.5 = cyan, 1 = red again)
--
-- easing functions: Back, Bounce, Circ, Cubic, Elastic, Linear, None, Quad, Quint, Sine, all In/Out/InOut
-- examples: easeBackOut, easeLinearIn, easeElasticInOut etc
-- More information about that: http://easings.net
--
-- shaderZoomCharacter(name, c_scale, delay, easing)
-- shaderZoomObject(object, c_scale, delay, easing)
-- shaderFollowCharacter(name, c_scale, delay)
-- shaderStopFollow()
-- shaderViewportInterpolationPoint(x,y)
-- shaderViewport(zoom, x, y, rotation, delay, easing) rotation in 0-2Pi (full turn)
-- shaderPan(offset, delay, easing, axis)
-- shaderRotate(degree, delay, easing) -- degree values 0 to 359 (automatically converts value to Pi)
-- shaderZoom(zoom, delay, easing)
-- on: 1 = on, 0 = off
--
-- shaderNoise(on, strength, delay) -- strength * noise + color, so strength < 0 creates black noise and > 0 white
-- shaderBlur(radius, delay)
-- shaderSaturation(factor, delay)
-- shaderLightness(offset, delay)
-- shaderContrast(contrast, delay)
-- shaderHue(target, delay)
-- shaderColorize(hue, strength, delay)
--
-- shaderActivate()
-- shaderDeactivate()
--
-- shaderGlow(on, radius, exposure)
-- shaderAddEffect(name)
-- shaderRemoveEffect(name)
-- shaderEffectParam(shader, name, value)
-- shaderLamp(index, type, position, targetpos, falloff, ambient, diffuse, diffusefactor, exponent, cutoff)
