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.
Added tarball glChAoSP_release.tar.gz for Linux users: it's same but maintains executable attributes for binaries.
Starting from 1.4.0 release, there are no more binaries in the source code repository.
Please use last glChAoSP_release zip/tar.gz archive, with internal directory structure, or build the current WorkInProgress (WiP) release from source code (I am available for any problem).
WebGL live / online version 1.5.0
The WebGL/WebAssembly version is online at this link: wglChAoS.P
With the new Attractors website pages you have full access to math formulas, computational code, and permit you to explore interactively any single attractor: AttractorsFormula
Soon also
