This instructable describes how to upgrade your globe to a motorized version. It looks amazingly better on the shelf when it is slowly rotating, and any demonstration with your kids (to explain the day/night cycle or the seasons) will gain in interest. No need to rotate the globe by hand while painfully holding the flash light with your teeth.
I will not describe the operation of the motor since it is very well done in this instructable: -Stepper-Moto... you might want to check it out first since some of the steps bellow are better carried out if the motor is powered and rotating.
This globe, rests onto a plate that can be taken out. Take it out. The large axis that protrudes has to be cut so that the plate will be flush with it when resting on its position. After you cut the axis (leaving 2-3mm of protrusion), place the plate back on its stand. It should rotate freely. If not, shave the small plastic fibers (left over from the cut) with a knife.
The most important part is to stay on axis. Do not drill if you are forced to be off axis. Prefer to drill from the top by bending slightly the globe arm away, it might actually guide you since the top part of the arm is precisely on the rotation axis.
We need to use the 4-minute epoxy because it quickly becomes not sticky, and doesn't drip. For a short period of time (1 minute) we will be able to adjust the two pieces on the same axis by inserting the still hardening assembly into the globe axis. The glue will not drip and stick the axle into the globe axis at that point.
Insert the axis in the globe and plug the base plate on the axle. Glue the motor to the globe axis, a few drops of epoxy should do it. Don't use hot glue since the motor could get warm at times and un-glue itself away.
Animation of a rotating globe of Jupiter's moon Ganymede, with a geologic map superimposed over a global color mosaic. The 37-second animation begins as a global color mosaic image of the moon then quickly fades in the geologic map.
you have semi-transparent edges, not really visible, but transparency is exacerbated with the Spinning filter, removing alpha solve the problem
Or just put a gray layer underneath and merge them, then do the spinning globe
You certainly are a genie. The rotating earth looks truly amazing. I like the way that it is visible through the large window. Your boys are lucky to have a travel genie in the family. I think it would be very satisfying getting requests and fulfilling them.
I suppose rotate the Earth meaning in relation to the camera. It would be weird rotating the Earth relative to the Sun and Moon (with time stopped) so that what would should be noon turns into midnight!
Our MOVA Rotating Earth Globe with Clouds creates an awe-inspiring experience for your viewing pleasure. This breathtaking satellite view of our planet creates a visual of the Earth and its clouds as they rotate slowly in their natural motion. Explore the beauty of our planet with this captivating globe.
The Blue Planet, as its name rightfully suggests, comes studded with a beautiful blue gem at its center in the form of a detailed, rotating planet that tells time. The rotating hemisphere boasts of a significant amount of detail, with accurate oceans and landmasses, and even relief work in the form of mountains and valleys micro-carved onto the globe. The globe rotates on a central axis, surrounded by two rings with minutes and hours carved into them. While the outermost hour ring remains static, the minute ring in between rotates too, and a compass on the globe helps point out the time.
So here i go.For the first functionality i added rigidbody to the globe and started rotating the globe adding torque in direction towards the swiped position.Then just clamped the Y axis to a certain angle so it wont flip the globe around.Pretty easy and it works OK.
Then i created a method which gets my current latitude and longitude from the center of the globe so even if i spin the globe with torque i will always know the current latitude and longitude from the globes center and i will interpolate the angles without any problems.Now here is where i got it wrong.
When spinning the globe with torque of course, it does not angle the globe by the lat/lon angles.Here when the player spins the globe with the first functionality and after that taps over the planet the interpolation starts with the correct lat/lon, but it seems that this is not enough to get the correct current rotation.The result goes like:
Regardless, what operation would I use to globe-rotate the raster so that it was aligned with the shape files? To be clear, it seems like the two data sets agree on coordinates and projection (WGS 84), it's just that the shape files all put the americas on the left and for whatever reason the topo raster puts them (and part of europe/africa) on the right.
This tutorial shows how to create a rotating globe using React and D3. We'll use React to create a component which'll contain the rotating globe and D3's powerful geographic functionality to deal with transforming our geographic data into SVG.
The first step in setting up a projection in D3 is to choose the type of projection we'd like. We'll use an orthographic projection as this'll make the earth look like a globe. Let's create the D3 projection function at the start of our render() function:
This tutorial has shown how we can use React and D3 to create a rotating globe. React allows us to build a reusable component that handles the creation and updating of our SVG while D3 provides the geographic cleverness.
Have a play around with the code on Codepen - see if you can change things like the size of the globe abd the speed of rotation. If you're feeling more adventurous you could explore some of the other projections that D3 provides. There's quite a few to choose from!
