What's new in v1.5.3
In TransformFeedback multi-dot emitter (for "continuous" dp/dt attractors)
- Split View: in addition to PiP now is possible to visualize, side by side, both cockpit and standard view
- Cockpit view have now possibility to select both fixed distance (from core) or fixed time interval (variable distance by speed)
- Magnitude (size) for starting emitted particles
- Magnitude intensity
- Magnitude attenuation over time
Other news
- Available settings for glow effect: mixing between standard gaussian-blur and "pure" glow effect
- wglChAoS.P (WebGL) now have also dual pass gauss/blur/glow effects
- new fastPRNG tool: it includes xoshiro / xoroshiro (Blackman/Vigna), xorshift and other Marsaglia algorithms.
*Please view previous releases for all news
Known Issues
- Some attractors, presnt in the additional SavedList, may not have optimized parameters for the new features
Changes:
- binary file for Windows 32bit is no longer provided, it can however be compiled via VisualSudio.
(or contact me if you need it)
installation
No installer provided / needed: just download the glChAoSP_release.zip binary archive (it contains all binaries for all O.S.) and decompress it in a folder whatever: only the internal directories structure must be preserved.
Added tarball glChAoSP_release.tar.gz for Linux users: it's same but maintains executable attributes for binaries.
(I am available for any problem).
WebGL live / online version 1.5.3

What's new in v1.5.0
News from previuos beta
- Better and more natural shadows
- Scattered shadow alternative (using random Poisson disk)
- New Attractors: Qi-Chen, Qi 3D, Chen-Celikovsky, Tamari, Shimizu-Morioka, Bruke-Shaw, Popcorn4D simple
Already present in v1.5.0beta
The main feature is the transformFeedback multiDot emitter added.
Now all dp/dt attractors (yellow tag) have an additional new emitter type to visualize them in a progressive way and/or with multiDot (spray) effect.
Is also possible to travel, in first person (cockpit view), within the particles, following the evolution of the attractors.

|---|---|

 |
New menu is available to adjust these settings:
1) Panoramic/CockPit dots/s: different emitter speed for any view
2) Number of dots for each step, real dots/s emitted are: dots/s * Emit#
3) Multiplication factor of initial radial random speed
4) Air friction/deceleration
5) Point size: there are 3 different "pointSize" for: singleDot emitter, multiDot emitter and cockpitView
6) Particles LifeTime, in sec.
7) LifeTime attenuation: when the lifeTime ends, in blending mode, the particle attenuates the intensity of this factor, any second
8) Wind direction and intensity (in units/s)
9) Gravity/Acceleration direction and intensity (in units/s)
A) Toggle cockpit view and related settings (following controls)
B) Smoothing distance: in blending mode attenuates the intensity of near dots by distance
C) Clipping distance: skip to draw closer particles
D) PiP (Picture In Picture) feature
E) TagretView is the current emitted dot, PointOfView is positioned on the wake: it adjusts the distance from head (it follows the attractor direction).
F) Move back the PoV: it follows the vector PoV -> TGT
G) Rotate the cam around TagretView, or better: around attractor head (last emitted dot), use reset to reposition the cam
H) Move forward the TagretView position
Other new features:
- GloboToroid attractor (thanks to the suggestion of Joe Carmon)
- Synchronous OpenGL mode option (for slow GPU)
- Speed up 30% DLA3D
- More AO (ambient occlusion) accuracy: range check
- Save clipping planes settings
Fixes:
- MacOS version now is fluid: solved stuttering problems
- Now buffer stops exactly on the end
- Little issues with shadow and clipping planes
- Several fixes of new features present in v.1.5.0beta
- Some minor general bugs fixed
Known Issues
- Some attractors, presnt in the additional SavedList, has been previously saved with not optimized parameters for the new shadow algorithm: try to select AutoLightPosition (and/or tell me if you have problems)
Changes:
- Attractors are identified by color (not anymore by symbols)
- The selection identifies the attractor currently displayed
installation
No installer provided / needed: just download the glChAoSP_release.zip binary archive (it contains all binaries for all O.S.) and decompress it in a folder whatever: only the internal directories structure must be preserved.

Starting from 1.4.0 release, there are no more binaries in the source code repository.

glChAoS.P v1.4.3 beta
Adding save PNG file with transparent background, from this proposal:
This is a beta, with no other changes: only Linux and Windows binaries.
The source files are not still synchronized.
- left-shift+PrtScrn -> normal capture (without dialog)
- right-shift+PrtScrn -> capture with transparent background (without dialog)
- left-ctrl+PrtScrn -> normal capture (with save-dialog)
- right-ctrl+PrtScrn -> capture with transparent background (with savedialog)
glChAoS.P / wglChAoS.P v1.4.2
New 11 unedited attractor types
An absolutely personal and original transposition in 3D/4D of famous 2D attractors:
 |
 |
|---|---|
 |
 |
 |
 |
Full descriptions, math formulas and code in the relative webpage: PopCorn, Mira, Hopalong and...
now any single attractor is also explorable interactively via WebGL/WebAssembly directly from website.
What's new in v1.4.2
- 11 new attractors type
- Added widget to change background color
- Shadows have "automatic bias" regulation, in base to distance: it avoids the dark halo in far objects (the bias setting remains to fine tuning)
- Added option for Slow GPU (Settings (F8) menu): it starts any attractor in PointSprite mode, that is faster of billboard, and with GLOW OFF (it's critical mostly in macOS), after the attractor is loaded you are free to select whatever you want: also BillBoard and GLOW
- SlowMotion function for non chaotic attractors (dp/dt), to view the evolution and cyclicity (in beta: don't save yet the values)
Changes
- Object auto/idle rotation ON/OFF (default now is OFF): toggle idle continue object rotation with "G" key, or form View tools (F5) menu
- Object PAN/move, with mouse, now use CTRL+rightButton (instead SHIFT+rightButton), to avoid conflict with WebGL release (Firefox uses SHIFT+rightButton for context menu and cannot be disabled)
- Now the object is auto-placed in center of the view, when changing the Center of Rotation
- Default window size, for the first execution is 1680x1024 (instead of 1280x1024): you can save size and position that you prefer from Settings (F8) menu
