Thanks to all for nice comments.
I share the same prolem of navigating, I did this to make a "3d map" of my next animation-project:
Nice trick for making 3D map
Super-impressive Buddhi! I loved watching this. That is 165 hours of CPU time very much appreciated, thank you. Is it not possible to get inside that structure in the very middle? It looked like there were holes in it. I really wanted to peek out of the window on the left at 2'35", it looked like sunny weather outside :-)
No, it is not possible to go inside the structure in the middle. I tried. All holes are closed
At the very beginning and ending of your video, are we on the outside of everything, with just a painting in the background? Or are we inside some outer reaches of the same structure?
It's only background texture
I am still struggling a bit to navigate as beautifully as you do, and I wonder if you can share a little advice. I spend a lot of time setting up my keyframes, but often I end up accidentally cutting through pieces of the fractal when I mean to go around an obstacle. I believe this has to do with how the parameters are interpolated. I am a bit better at navigating in Mandelbulb3D, because it lets me choose the curviness of the bezier interpolation. I don't know if this is even possible with Catmull Rom splines, but if it is I wonder if you have any plans for letting the user adjust the degree of interpolation, which might help me navigate a little less clumsily.
Regardless, I wonder if you could offer a little practical advice about how you set up your keyframes. Basically, I wonder if you tend to steer, then move forward then save a keyframe, or do you move, then steer, then save a keyframe, or do you steer in the middle of the path in between keyframes? I keep experimenting, but without the ability to do a fast preview, like the animated gif in MB3D, I am wasting a lot of time rendering lowres test animations and then trying to figure out how to fix the one or two keyframes that cause the problem. Besides cutting through corners, I also sometimes try to zoom up to something, and then zoom back away, but the program overshoots and smashes me inside the fractal when it renders the animation. Basically, it just looks and feels like I'm driving drunk through the fractal, and that's not so good!
Any advice on how to navigate better would be great! (Feel free to jump in, anyone else too.)
Keyframe editing is not so easy also for me. I also have to render previews and correct some keyframes. I think, now I have to focus on building some better keyframe editor and make some fast preview (low quality, low resolution) of animation. I have also to add some other kind of interpolation, because in Catmull Rom splines there is no possibility to adjust angles.
