Great images, and kudos for creating an entire 3D bluray production. Your movies look texture-mapped. Do you project 2D textures onto the fractals? I've tried this myself, using the following approach: vec3 color = texture2D(tex, p.yz)*normal.x
+ texture2D(tex, p.xz)*normal.y
+ texture2D(tex, p.xy)*normal.z;
Basically, to avoid the texture looking stretched in some directions, I choose the projection based on the surface normal. This works, but the resulting texture will be blended together of several textures. Here is an example:  Here the same image with a grid texture:  But the method works best when the surface hasn't got rapidly varying surface normals. How do you project onto 3D? |

I use the same approach: vec4 surface_3D(float zoom, vec3 pos, vec3 norm) { vec4 surf1=surface(zoom*pos.yx); // left/right vec4 surf2=surface(zoom*pos.yz); // vert vec4 surf3=surface(zoom*pos.xz); // top vec3 blend_weights = abs(norm.zxy); blend_weights /= (blend_weights.x + blend_weights.y + blend_weights.z ); return (surf1*blend_weights.x + surf2*blend_weights.y + surf3*blend_weights.z); } It is a fake, of course but ... it works.  I used also: vec3 blend_weights = abs(norm.zxy); blend_weights = smoothstep(0.5,1.0,blend_weights); blend_weights /= (blend_weights.x + blend_weights.y + blend_weights.z ); Sometimes it looks better but it depends on picture. |

Yeah, they use: blend_weights = (blend_weights - 0.2) * 7; blend_weights = max(blend_weights, 0); I tested nvidia algorithm but I do not see significant difference. |

_______________________________________________________________________________________________________________________ ______ Greetings and Salutations Master, ALEXI Its been a million hours or more, you've been busy! THERE you go again, taking us along for another one of your great fractal time cruises in fractal mind scape alternate, Time, away from out of our comfort zone, of knowns time, to unknown spatial time!
Long live the total time, every second spliced by your mind to our kind, you do so pleasure our eyes with this journey, which proves to us, you're a Time Raider Pirate Traveler, full of intriguing visions! You definite got this viewers attention, great job! Glad to see your work! We really appreciate it and don't mind telling you so! What we see here is : We appear to be in a Fractal Jungle, a forest in breeding, there are distance spires, lines, cables, electrical lines, that are alive and hanging resembling spiders and circles, portals belonging to mind scape's too scary for us to follow! Again love your background skies so real!
Thanks for sharing this mentsl taxi ride, into one of your minds super creations! Really cool! Enjoyed the trip! Yes, the music is perfect! It more than tells the story. It says it all, within its beauty lies dark tantalizing touches of danger, good, we are dare devils anyway, unafraid, Thanks again! The Fractal Forum the possibilities are infinite . |

Nice videos, peaceful. Jealous of the hardware too!

I just placed an order for the Blu Ray. Surprisingly your order page sent me right to Paypal.
I am situated in Germany. The shipping address stored in PayPal states "Deutschland" as country, I hope this is translated to "Germany" automatically when PayPal sends you the recipient Information. Otherwise Canadian post might get confused.
Your shipping rate seems relatively low. Let me know if I need to send additional funds in order to have this shipped internationally.
At this price, the 3D Blu Ray seems a steal.

The disc has been sent to your address today I hope you have a 3D TV. P.S. As far as see, you live in an apartment building, but your address do not include the number of the apartment. |

Ehrm please discus private details in private! No need for appartment num here Right, the recipient's name genereally identifies the apartment here. Which occasionally confuses the post man if two building residents have similar sounding names. I am looking forward to this disc. I own a 3D monitor and intend to buy a 3D TV soon. Christian |

This content has been optimized for 55" screen. If you have 40" -70" - it's OK, but I think that your monitor is 27" or something like that. The thing is that the objects can be located quite close to the viewer (half of the distance to the screen). In case of big TV screen that's fine, but if you use a monitor, it may be too close to your eyes. One more screenshot (new stuff):  ... and video (see screenshot 3 posts above):
