** Macworld Editors' Choice Award Winner! ** Smithsonian: “Immersive.” CNET: “Spectacular.” Macworld: “Exquisite.” FRAX Frax is an art program that puts the “equations of nature” in the palm of your hand. Frax is powered by fractal geometry, the same principle that creates patterns of self-similarity in our natural world. From spiral galaxies to hurricanes, from tree limbs to branching blood vessels, the universe is filled with endless variation and staggering beauty. Frax visualizes this natural geometric code, so you can explore vast animating digital landscapes and make a masterpiece on your touchscreen. EXPLORE Zoom deep into your creations. Use multi-touch gestures to fly through and explore intricate shapes and patterns. Tilt-to-steer through animating digital worlds, as you challenge yourself to chart a course for a long and beautiful flight –all at a depth range of a trillion-to-one. DESIGN Unleash your inner artist with complex color gradients to smoothly tint and shade your fractal shapes, two light sources for glossy reflections, and novel textures. The combinations are endless: supersmooth or wildly chaotic, metallic sheen or pearly white, subtle shades, stark monochrome or screaming supergloss. Or upgrade to Pro to access almost 100 parameters and controls! SHARE Then share your creations with your friends via Facebook, Twitter and text. Or invite other users to step into your animating world by sharing a live preset link. You can render high-quality images to your photo library or create ultra-high quality 200 Megapixel renders with an IAP. And for the first time, you can now record VIDEO of your Frax animations directly within the app! (Pro IAP required.) Our users have put their designs on canvas, posters, scarves, T-shirts and textiles. The creative possibilities are endless! What will Frax inspire in you? We hope you enjoy Frax!

About

Fractals Julia

Features
Read full description

Applicazione che permette di esplorare l'insieme di Julia partendo dalla scelta della costante C nell'insieme di Manderbolt. Effetti grafici molto particolari si possono ottenere giocando sul numero di bit con cui sono codificati i colori che può assumere un valore da 3 fino a 256 bit. È inoltre possibile ottenere tutte e 6 le combinazioni di colori (RGB, RBG, GRB, GBR, BRG, BGR) che diventano 12 se spuntiamo la casella di inversione colori. Dato che gli effetti grafici più interessanti si ottengono scegliendo la costante C nel set Manderbolt sul bordo del set verso l'esterno, potete ingrandire quanto volete scegliendo il punto più vicino possibile ai bordi. Allo stesso modo si può anche ingrandire quanto vuole sul set Julia per vedere interessanti dettagli che si intravedono dalla figura completa nell'intervallo -2, 2 per la parte reale e -2i, 2i per la parte immaginaria . Buona esplorazione dei frattali di Julia.
