Good afternoon, everyone. Okay, so. robotic Mars exploration. Wednesday March for us two weeks from tomorrow 7pm. So if you're on Facebook, you can. You can share this event and indicator coming or not. you're interested. In speaking with us he does his bachelor science honors in computer science complicated and 79. As Java with NASA is allows him to personally participate in putting robots on other planets. So here's the link to the zoom. registration. funny. I think. The way I can register myself. register. yeah. ingenuity, a helicopter that will try the hear me. Let me read it, because it's better than. perseverance will acquire set of samples and leave them to be right back to earth lady this decade, with the giant us EU mess mission. which the totality of which is called the MARS sample return campaign. perseverance also carries a small helicopter called ingenuity, which is intended to technology demonstration of the first heavier than aircraft there to attempt flight on another planet. So this lecture will give a brief introduction to Mars exploration and these missions. that's a depressing thought about Amazon drones. colonizing the whole is also solar system. I guess some good news is that Jeff bezos is retiring. So he's not directly steering. The company towards evil or not. No, yes, the fans and some detractors as well. yeah anyway so. I didn't mean to start a conversation about. Amazon, and so forth. I just want to let you know about this information, so this is on the car your computer science page, I think, somebody posted it on. I see triple s. This year's like to. share it with anyone else you you're welcome to. come here here's the link to the nasa.gov site mars.nasa.gov site. Dr Matthews profile. So much interesting stuff here. And there's also multimedia in. Some images to. share that. ingenuity. One can use and download. The original. 4k Y2K. Need for two megabytes PNG. So any questions or concerns from the other day, did you see my updated sketch. For the. doesn't sketches and I updated. again. Simplified it a bit from what I had originally and I cleaned it up. So that. Instead of just thinking about the events. and attaching the events to particular. controls. These event handlers. So this one just changes the toggle. So when I click on the canvas bounding box. Another one to calculate bounds. So that. That doesn't have to be done, all the time, and it has to be done when there's a change in the fonts. So what i've done is. i've. So this line of code. Associated Press. associated with the toggle function. With the event when the most is pressed on the canvas. That gives me a bit more control. So, and then for the calculate Downs I do that lunch here. In this setup. And then here i'm. Also associate the. The function, which is released on the slider to recap, then bounce up recalculated. You can see how it works. Time being done when the most is released. Okay. Any questions about that. shower at 330 today just two three to 430.

Okay.

Let me go back to. This one. Which is going to deal with our next assignment. I just want to recreate an error message here. OK, so now. i'm starting with my. image on the website. on my website. http website. wwe to that siesta you're trying to see. So on the console I get this message. Much more detail there. Is a javascript console. console directly here. Next content. https page. Page loaded over https requested an insecure element. So that's an issue there that's what the message is. From. So if you get something strange. you'll get a console message on in the editor. But then, you might need to go into the javascript console for your browser. To get some more information. Okay, so. There may be made very obese include. In the message anyway. i'm gonna comment, this one again. On the. I O version of my website, which is https. secure. Okay, so we're creating sounds based on image. So function preload means. This is called before setup. So that we can begin. maker request for her assets. To be loaded and then we can do load pixels with an image. And then here i'm allocating an array. So everyone and exchange with the range. of experiences with race. Okay, so the idea is we're. store related information. In a way, that's addressable. So we have all of one thing. So we're creating a. business case for well. we're creating a collection of. locations, just to indicate which excellent which part of the imagery visit already which pixels. Read. So the size of the. array called visited is. The wait times the height. And we're going to make initialize to 07 To begin with, and shut up none of the pixel seven okay. So first you're going to create a canvas. Of with with times height size. So no stroke and means no outline. That ground. Is 192 which is kind of a grayish. And then the frame rate. For.

and

Center the image. The width and the height divided by two. So there's a p. So then here, creating the sound synthesis. Creating an envelope. Which is. The sound of the produce, so how attack is. How quickly. It initiate and then UK time is how quickly or slowly it decays. And then the sustain percentage, and then the release time. Look at some examples of that in a minute. Set the range for the attack level and the release level. And then we can attach an oscillator. or associate an oscillator see. I see envelope. So we can choose between sign and triangle and Socrates and square oscillators. And then the oscillator aptitude is controlled by. The envelope. So, then, we start the oscillator. We have a frequency and 400. And then we have a sound recorder. i'm going to take the input from the envelope. Take the input set the input of the quarter to be the envelope. And then we're going to. create a sound file. and To set the record to record the sound file. setup so that's. The sound generation. And we start the. Sound recording. We start a blank canvas and we can we can go into the draw. So what i'm doing here is then. Getting a new X and y position to draw. To begin with, is said to be. The Center of the image. So if X is outside the range. of values for the width then we. Then we pick a new X. And if lies outside the range of values for the height. and weight pick a new lie. So we test whether or not that x&y has been visited before. So if it has been visited. one. I believe, beginning. starts at zero. This is another way to say. Yes, the X and y coordinates that we've picked it's already been visited then we pick. And we start from the beginning. location zero which would be X equals zero y equals zero.

Afternoon!

good afternoon

the first zoomer mars rover, it will fly an experimental drone on the martian surface
-
The amazon drone packaging empire will colonize the whole solar system!
-
XD
-
I've seen a youtube video on Ingenuity. The rotors have to spin MUCH faster than normal helicopters to take off on mars.
-
he also literally said he will sink money into space travel
-
martian life: UFOs!
-
nope
-
Nope all clear
-
yep
-
yup
-
Prof, can you give us the attendance password please?
-
okay
-
cool blood splatters
-
the screen appears to be super zoomed in and the preview seems to be very small
-
is that intentional?
-
no
-
So it takes an image and reveals it pixel by pixel. Sound is based on the color?
-
Makes sense. Thanks.
-
yes
-
usually red means high pitch and purple means low pitch right?
-
infra red and ultra violet light. the color spectrum
-
sry, its the other way around
-
sorry, did I miss the password?
-
not worked for me.
-
Student password
-
worked
-
a color of an image's pixel?
-
oh okay, thanks
-
thank you
-
thank you!
-
Thanks
-
thank you
-
Thank you
-
snow day?
-
Thank you
-
Thanks. Cya thursday
-
stay safe! see you Thursday!
