- core: redone ambient, sun and sky LUTs

- custom scripts: added custom script functionality

# Scripts are linked to PPfilters. Its will be loaded, if the script has the same
name like the current selected PPfilter.
# Scripts must be placed in \system\cfg\ppfilters\pure_scripts
# Have a look in "pure.lua". You will find the most things there.

- pp: finetuning exposure and autoexposure

Pure 0.15

- core: added proper fog calculation

# added fog layers: atmosphere, humidity, smog, mist
# atmosphere (distant fog) color is calculate from horizon color (this will make
sure it fits graphically)
# fog parameter LUTs with dense as index
# The fog layers are independently mixed atmosphere color.
# After that, they are mixed into each other, dependent to their normalized dense
relevance.

- core: sky shader, reduce sun shape saturation to 50% to have a better glare
behavior (CSP 1.76p12 +)

- track adaption:
# added first simple base, to adapt tracks.
# In track config file, you need to set:
# [Pure]
# FOG_SHAPE = 0.00
#
# I want to keep this simple, so for the start i just have 1 parameter,
ta_fog_shape:
# ta_fog_shape wil correct the different maps. It like a factor to shrink the fog
extents, to look right on different maps.
# For example: a track like SRP does not need such correct, it has no "fake
distant" textures or objects.
# But a track like "ks_barcelona" needs a big correction factor. It has very near
texture walls, which are faking a distant.

- pp/script: pure.lua, other godrays settings

Pure 0.16

- core: added LUT class

# a class which collects all LUT functions
# huge performance improvements in LUT calculations

- Pure improvements:
# trying to minimize memory allocations to the lowest level
# converting functions to access an existing variable and not creating new ones

- core: changed fog calculation to a much more complex one

# fog is calculated in stages, that interfer each other in the sequence of
calculation
# "overcast" uses also a fog stage
# much better color mixing and adaption to light changes
# added material fogs (rain, smoke, sand)

- core: sky shader, many small tweaks

- added ambient light calculation from sky color, fog and night light pollution

- added "directional ambient light"

# is generated out of "overcast" and fog's backlit

- added weather definitions

# done in a class now, more clear

give a little more performance)

- sky:
# little tweaks of the hue with sunangles between 0-9° (more purple with very low
visible sun)
# little lower saturation for sunangles between 3-20° (less artifical look)
# lower brightness of sun opposite sky with twilight

- function sharing (pure_sharing.lua), added:

# Pure_get_AE(), return not the Yebis AE value, it return already the right
brightness multiplier AE is trying to gain the picture's brightness
# Pure_set_AE_manual(b), set the AE to manual. Brightness regulation is then
neutralized and can be therefore customized.
# Pure_set_AE_multiplier(v), set the final brightness multiplier, to restore AE's
behavior

- ppfilter/pure script: added pureHDR

# less AE controlling
# added colorgrading from __Sol_HDR filter

- ppfilter/pure script: added pureEYE

# a copy of pure ppfilter
# AE is manually controlled.
# It simulates the behavior of the human eye.
# Adaption to lower light takes longer than to higher light.
# If you open /pure_scripts/pureEYE.lua you see the example code for setting AE to
manual mode and setting the new brightness value.

- cloud-system: using CSP 1.76p134 asynchronous update

# Since this CSP version, Pure can put all cloud calculations to another CPU
thread. So the main renderer do not wait for finished clouds calculation.
# This will give you many fps back, because those "luxury calculation" are no
longer part of the synced renderer.

# The script manages, how the texture are displayed (sunangle, lighting and
opacity)
# For every weather a list of sections can be scripted.
# A section has a texture and can have a unique lighting
# read more about this in the Pure skydome manual.

jumps

- skydomes: removed the multiple resolutions logic:

# files no longer are splitted in resolutions (4k, 8k, 16k)
# there is only 1 file with the maximum resolution and mipmaps.

# This value controlls the minimum amount of glow strength in not foggy weather.
# Sol's minimum value is 0.3, Pure's minimum/standard value is 0.5.
# add to track config:
# [PURE]
# MINIMUM_GLOW_EMISSIVES = 0.25 ;[0.0 - 1.0]

Pure 0.95

- ambient light/ adv. ambient light: fixed calculations for sunangles between 17° -

- track adaptions.ini, added first list of real distance tracks.

Pure 0.105

- fog: more tweaks of humidity

- track adaption: added many tracks with real distance

- config: added a temporarily set of "gamma" parameters

# with CSP 1.79p9, lambert gamma is introduced and will help much with tonemapping,
independent of PostProcessing
# The lighting of materials is less influenced of the sunangle now and therefore
less sunlight can be used.
# This gamma has its most effect with low sunangles.

Pure 0.106

- core: fixed a bug in utilities connect library (set, init)

# The last connect item was not handled
# In Pure Config, the last element of the PP custom script UI was not handled and
was always 0

- scripts, added new function:
# PURE__set_ExpCalc(1.0), You can now mix Pure CBE exposure and YEBIS exposure
# PURE__set_Lambert_Gamma(1.7), Set new CSP gamma for materials
# If PURE__set_Lambert_Gamma(-1) is used, Pure still uses its sunlight hack to gain
the lighting of materials with low sunangles, with other negative consequences.
# If the value is positive, this light hack is bypassed and sunlight is at normal
level.

- default script (for ppfilter without a script): added sliders for interior and
exterior exposure adaption.
# Pure's CBE exposure is used, but mixed with YEBIS Autoexposure

- noPP/script: added use of new Lambert Gamma, plus an option to

activate/deactivate it

- PPfilter/script: pure + pureEYE + pureHDR-EYE, added Lambert Gamma

sunangles

- default script: some tweaks to improve AE<->CBE

- PPfilter/script: added pureCandy (eye candy ppfilter)

# a camera filter with nice glare, lensflare, saturation, contrast and a proper
AE/CBE exposure logic
# If AE is ducking under CBE exposure, gamma is lifted to prevent too dark
pictures.
# Its to demonstrate, how to use a dynamic balance of YEBIS AE and CBE exposure.

Pure 0.108

- skydomes: added support for multiple sections per sunangle

# if sections in the same weather are defined with the same sunangle, a section
will be then choosen randomly.

- skydome set: "default", added 5 more textures, rearranged textures

redirected to PURE__set_Lambert_Gamma()
- fog:
# made some changes to fog backlit
# added a sky gradient, to expand fog sunlit

- fog/skyshader: added a new LUT to compensate the sundisk look, when it is covered
by fog
# before a linear function was trying to compensate the fog cover
# now a LUT with nonlinear values compensate it much better

- skydomes:
# fixed wrong interpolation of hue, using angle interpolation instead of lerp
# added texture function "setDirectionalAmbient(hue, sat, level)", to define an
additional ambient ligth, which fits with the look of the texture

- skydome set: "default", added directional ambient light to the low sun sections
of dry weather

Pure 0.110

- fog: some changes to humidity look

- sky/shader: lowered the horizon brightness

# this higher horizon brightness is mainly a fix for the bleeched out horizon
texture walls of many tracks

- 3d clouds: fixed moving direction (corrected wind direction with CSP 1.79p25)

- added an AC system message if CSP version is not compatible

- config: added "ui.white_reference_point"

# With this, mainly the UI's brightness in VR can be customized
# If ppfilters use a different exposure base than the pure ppfilters, its possible
to recalibrate
# the ppfilters to "normal" white point levels (round about 20 at day, round about
1 at night)

- PPfilter/script: pureCandy, added the "Candy" slider

# this uses the "non hdr" mode: sensitometric tonemapping is used. Brightness is
adjusted via tonemapping factor.

Pure 0.111

- core: reorganized Pure utilities and app functions to work with multiple apps

- ambient light / directional ambient light: some improvements with cloud shadows

- ambient light: some improvements for daylight look

# for real distance tracks, a decent distance look with 0% humidity

- skydome set: "default", lower brightness of "overcast" skies

- PPfilter/script: pureEYE, some further work

# better brightness for mid light situations (overcast and low sunangles)
# new LUT, better resolution of high tones (LUT curve is like a reversed smoothstep
curve)
# different code to manage exposure dependent calculations
# nearly everything is commented now in the script

- PPfilter/script: pureHDR-EYE, a clone of pureEYE plus HDR controls

# added "peak brightness" and "paper white" controls, to adjust the HDR picture
dynamic and brightness

- PPfilter/script: pureCandy, some finetuning

- Pure Config: changed design generation, Pure config parameters and states are
addressed by name, not by id

Pure 0.113

- fog/sunlight: some more work and backlit:

# changed the dependency of fog (mist) and sunlight loss
# edited the LUTs
# adapted it to ppOff

- world: added simple rainbow control

bad weather

Pure 0.115
- pure sharing: PURE__set_Lambert_Gamma(v) is automatically calling
ac.setColorTexturesGamma() or ac.setLambertGamma(), depending on the CSP version
# ac.setLambertGamma() will come with CSP 1.79

Pure 0.116

- core: track heading is updated per frame

# Pure now calculates the right things, if Photo Mode's "Lighting angle" slider is
used.

- shaders: no wfx reset with changing active state

- ambient light: added distant ambient light support (CSP 1.79p32 and higher)
# distant ambient light is the ambient light in the distant
# so the near ambient light (the standard one) can be brighter, without influencing
the distant look of a track

- UI: added tabbar object

# Pure tabbars are dynamic in ther width. The single tabs are not changed in their
size.
# Tab titles are always readable. The tabbar expands vertically, if the UI width is
too small.
# tabs can have a sticker color.

- pure config: added distant ambient light

- Pure Congig app: switched to Pure Tabbar

- Pure Planner app: added Pure Tabbar

- Pure Planner app: added Time/date selection field (click right-mouse key on the
time-slider to open it)
# full detail time-slider with many informations
# added a calendar
# added a time multiplier configurator (needs some further design)
# adapts to app width

Pure 0.117

- config: added light.sun.speculars

- skydomes: speculars are controlled by skytexture's sun coverage

- exposure: YEBIS AE got a smoothing

# With PURE__ExpCalc_set_AdaptionSpeeds_YEBIS(low, high), you can set the YEBIS AE
speeds.
# If now speeds are set, the CBE speeds are used
(PURE__ExpCalc_set_AdaptionSpeeds(low, high)).
# PURE__ExpCalc_get_YEBIS_calculated_exposure() will retrieve the smoothened YEBIS
exposure value.
# PURE__ExpCalc_get_YEBIS_calculated_exposure(true) will retrieve the raw/live
YEBIS exposure value.
# added some necessary limits with smoothing values

- PPfilter/script: pureEYE, new attempt with YEBIS AE

# YEBIS AE limits are set via a CBE indexed LUT, so AE has a short range of working
# By using only the CBE value, the controlling is steadier and more predictable.
# better control speeds
# removed a flickering bug caused by the old code (happens when fastly reacting to
dark sceneries)

- Pure Planner:
# some work on the time multiplier design
# added live tab + live weather functions
# added custom location selection (! CSP will not update the track location - sun
trajectory is not changed)

- Pure Controller:
# added pureCtrl
# This is a very lightweigth script. It will only transfer the Pure Planner data to
CSP weather controller data.
# Due to the better data link with LUA apps, all calculations can be done in Pure
Planner.

working

- UI: added groups (treenodes) to collaps and expand a group of ui elements

- PureConfig:
# using groups for "pp adjustments" and "shaders"

- config: added "pp.gamma" and "pp.godrays"

# "pp.godrays" is already handled in PURE__getGodraysModulator()
# "pp.gamma" is already handled in PURE__getGammaModulator()

- pure sharing: added PURE__getGammaModulator()

- scripting: Gamma and Godrays user access

# if you use PURE__getGammaModulator() and PURE__getGodraysModulator() in your ppf
script,
# users are also able to control those via Pure Config "pp adjustments"

- sdk: added a sdk, which will route functions with uniform names to the internal
Pure functions you know from the scripting pdf.
# This will bring more order into scripting
# f.e.:
# "Pure_get_Overcast", but "pure.world.getOvercast" can be used instead of it
# "Pure_getVector(VECTORS.CAM_DIR)", but "pure.camera.getDirection" can be used
instead of it
# "__SCRIPT__UI_SliderFloat", but "pure.script.ui.addSliderFloat" can be used
instead of it
#
# Please look in pureEYE as a first example of the new order.
# For a complete list of the name aliases, just havbe a look in \sdk\pure_sdk.lua

- PPfilter/script: pureEYE, some AE finetuning, using new sdk function names

- install: fixed pure_install.bat, wrong folders, added pureCtrl

Pure 0.120

- Pure Planner: added "date, time,..." group to expand and collapse the time
selection
# right mouse click is removed

- UI: interaction changes !!!

# slider values are increased/decreased, with mousewheel, if mouse is highlighting
the slider
# sliders and checkboxes are reset to their defaults, with right mouse button, if
mouse is highlighting the slider or checkbox

- fog: some changes to atmosphere and humidity look of real distance tracks
# atmosphere is denser, to get a better distant look
# humidity becomes more denser with lower values

- core: more fail safe checks of script functions

# A wrong usage, when given such functions a nil variable, will not cause a wfx
stop.

Pure 0.121

- UI: prevent slider mousewheels edit, when user scrolls the page
- UI: fixed slider height and margin for proper focus detection

- 3dclouds: fake 3d cloud shadows

# added a logic to cover the sun, if it is covered by a skydome

- skydomes:
- added a section function (section:set3dCloudShadow_SunCover(opacity, size)), to
customize the sun cover, when using 3d fake cloud shadows

- skydome set "default": added some custom sun cover values for "Squalls", "Broken
CLouds", "Few Clouds" and "Windy"

Pure 0.122

- apps: Sol Planner 2.3

# fixed a bug with Load/Save dialog is beyond the screen limits
# If Sol Controller 2.2 is not active, Sol Planner is not setting date, time or
time-multiplier

- UI: fixed slider focus area

Pure 0.123

- fog: fixed wrong backlit with real distance tracks

- exposure: removed overcast influence

# This should be in a ppfilter script. Exposure should be calculated right in the
core, without weather adaptions

- added Pure alternative tonemapping

# to use it, activate in CM > settings > CSP > graphic adjustments > Scriptable
filters (Active, select "Pure PP Link")
# use "pureAltTonemap" ppfilter
#
# This Tonemapping will have artifacts, because it can only work in LDR range. So
the LUA PPFilter script already gets an LDR image.
# The range of the output of AC PostProcessing is halfed, so the script has some
range to work with.
# Therefore it gets twice the LDR range, but with half of the resolution.
# This tonemapping is just in an experimental stage, maybe for later integration in
HDR processing.
# Besides all this downgrades, it has many positive aspects:
# The most color inaccuracies happens in YEBIS, if Gamma > 1.0 is used. So for this
experiment, gamma in the ppfilter is 1.0.
# The LUA PPFilter script uses then its own gamma and color processing.
# The base of it is a processing in HSV color math, so the value can be processed
dependly of the saturation.
# The output picture has more accurate colors, also the visibility of low tones can
be much better.

Pure 0.124

- PureConfig app: fixed PPoff page

- distant ambient light: temporary workaround for distant ambient light is not in

advanced ambient light.
# Before adv. ambient light made the clouds brighter.
# Now clouds nearly stay at their brightness

- exposure: in dark sceneries, exposure now does not drop that much, when going
into CSP lights

- ambient light:
# more overall saturation

- directional ambient light: some tweaks and fixes of generating dir. ambient light
in overcast sceneries
# using less adv. ambient light
# using more directional ambient light, to create an illusion of diffuse light
coming from sun direction

- config: added "Shadows" parameter

# If the slider is 1 or 100%, sun and ambient are normal.
# If the slider is at 0, sunlight is off and directional ambient light do the
sunlight now.
# This willhave its own unique look.
# It can soften shadows.
# But it route sunlight (ksDiffuse) to ambient light (ksAmbient), which has
different effects on different tracks
# Maybe use this gently (0.75 .. 1.0)
