All available releases     ==> Release Notes (what's new)

Desktop - v1.7 (WiP)

• glChAoS.P - DeskTop - binaries available Windows / Linux / MacOS

WebGL - v1.7 (WiP)

• wglChAoS.P - WebG 2 via webAssembly - live / online using your browser - also for mobile devices
  • You can select Advanced Mode check box (default) or deselect it (Standard Mode) for low resources devices (mobiles/tablet/smartphones)
  • You can also to explore any single attractor, interactively, staring directly from web-page, using Explore button near/below any attractor formula: Attractors Formulas
  • WebGL release is a more limited/lightened version, but frequently updated/rebuilt with last commits

<p>&nbsp;<br></p>

To view all "chaotic-objects" currently inserted in current release, follow the link: Attractors Formulas
*any single object can be explored interactively via WebGL/WebAssembly directly from site.

Latest features from ver.1.6

<h3 align="center"> TransformFeedback → multiDot particles emitter </h3> 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.

Lorenz Attractor - click on image to "explore" it in WebGL
       use "v" key or "cockpit" button (from Attractors tools window) to switch to subjective view (on right)

<p>&nbsp;<br></p> <img align="right" src="https://raw.githubusercontent.com/BrutPitt/myRepos/master/glChAoSP/screenShots/cockpitSettings.jpg"/>

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

ver.1.4.2 feature: 11 unpublished attractor types: PopCorn, Mira, Hopalong and...

An absolutely personal and original "transformations" in 3D/4D of famous 2D attractors:

Particle System rendering features

• 100M of particles in minus of 1.6 GByte of VRAM.. up to 265M (4G VRAM): Slight (dot) Particles
  • only a vec4 (4-float) per vertex for position and color

With Billboard and PointSprite techniques

3D DLA (Diffusion Limited Aggregation) - DLA3D Video Example

This is an integrated version of more simple my DLAf-optimized repo that I used in glChAoS.P / wglChAoS.P for large-scale DLA3D growth, with possibility to export/import to/from PLY format and to continue a previous rendering.
