Latest features from ver.1.5.3

TransformFeedback → multiDot particles emitter

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)

 

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ver.1.4.2 feature: 11 unpublished attractor types: PopCorn, Mira, Hopalong and...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

PopCorn, Morrone 4D transf. (ssss)	Martin, Morrone 4D transf.	PopCorn, Morrone 4D transf. (scsc)
Mira, , Morrone 4D transf.	Mira, Morrone 3D transf.	Hopalong, Morrone 4D transf.

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.

Hardware required:

• glChAoS.P - GPU with OpenGL 4.1 or higher
• wglChAoS.P - Browser with WebGL2 capabilities (FireFox, Chrome or Chromium based browsers)

Theoretically all graphics card that supports OpenGL 4.0 supports also OpenGL 4.5, depends only from drivers (and O.S.)

About the GPUs that support the OpenGL 4.5 (with appropriate drivers and OS permitting): - NVidia starting from GT/GTX 4xx series - AMD starting from HD 5xxx series - Intel starting from Ivy Bridge/Bay Trail CPUs (with HD 4000/2500 graphics)

Hardware recommended:

• GPU starting from AMD HD 7970 / NVidia GTX 670 or with better performance
• CPU with 2 or more cores

About performance

Glow effects, mostly with sigma > 5, and DualPass/Shadows/AO requires expensive calculations in terms of performance

If you have slow performance try, in this order: - Disable DualPass rendering and/or AO and/or Shadows - Disable GlowEffects and/or FXAA - Prefer Pointsprite: on AMD and Intel GPU (sensible differ
