All Things 3D | Peek A Boo... (4K Apple ProRes/5.1 Audio) @allthings3d | Uploaded May 2021 | Updated October 2024, 23 hours ago.
In this little teaser for "Ingenuity in VR," we have added a new series of rocks and boulders with the unique characteristics of a blue/green oxidation seen so prominently in some 'earth" color balanced images. However to keep Mars, well looking like Mars, we only do a grey balance, and adjust the single light source to 5500K, but bringing more of the natural color to the rocks and other surfaces that have been smoothed down by ancient water & wind currents, but also to reflect that there must have also been volcanic activity millions of years ago, since many of the rocks have pits. It also shows that the rocks have a lot of copper and iron, which reflects the different colored oxides.
Ingenuity Technical Notes:
After talking to helicopter expert Wayne Johnson, and one of NASA's consultant used in the design of the Ingenuity Helicopter. I have learned that it only has three rotors speeds, off, idle, and full speed. Vertical thrust, and vector positional changes are all done with coordinated & differential pitch changes to the propeller blades about 400-500 times a second. I had already read that, but what I didn't know was that spinning on its Y axis, yaw rotation that it is also done with differential pitch changes to the upper and lower props to create the necessary rotational torque to move the body in a spin. By differentially changing the upper and lower props pitch, you don't lose altitude and the motor RPM never changes. This reduces strain on the motors and more importantly creates a flat power curve with only the initial velocity change from off, idle to full speed creating the only surge. This goes a long way in increasing flight time, but also reduces stress on the Li-Ion batteries.
Next week, we will be ready to show off what a "360" panoramic would look like if Ingenuity were to take four or five overlapping images based only on either 90 or 72 degree yaw rotational shifts. As well as the very first "real time" video capture of "Ingenuity in VR" from the perspective of the MastCam-Z camera and the FPV view from Ingenuity's RTE camera. Both modes will be available in flying in the Jezero crater. We will also take video of our hands using the controllers to show how they affect flight in the real-time video. Getting pretty exciting on our end as we draw nearer to "Ingenuity in VR's" first VR flight.
