Python 3D Graphics Tutorial 5: Bouncing Ball Simulation in Visual Python

You guys can help me out over at Patreon, and that will help me keep my gear updated, and help me keep this quality content coming:

In this video we show step-by-step instructions on how to understand and use parameters in 3D design and modeling in vpython, (visual python), and how to bring your models to life. I do not assume you are an expert, so these lessons are designed for complete beginners.

I AM LEGNED!! It's so amazing how at first, I was a cheap lawn chair, and I could hardly code
but with your AMAZING TUTORIALS, I am now a LEGEND!! Thanks SOOOO MUCH

[Kurt-kjjh]

I'm legendary Lawn Chair again, after watching some of the video, I found out what I needed to do. Mr. Paul is a Legendary Teacher!

How can this Course got just 160 likes ? these are golden lessons Mr PAUL is offering us!!

The happiness and the satisfaction when a code is correct and it works properly , is a amazing thing. Those who have experienced it knows how it feels .Finally I AM LEGEND.

[cbrombaugh]

I AM LEGEND! I was yelling so loudly about the duplicate variable names that I thought you could hear me in Africa, but I was wrong. :) it was easy to get confused about all those names. Thanks for another most excellent lesson, Paul.

I learned the whole Arduino with his videos.
I am gonna do the same with Python

[TheSudouser]

Fell short on this one like a folded-up lawn chair but learned a lot from the attempt. Not discouraged, more determined!

[JKamohoalii]

You are an amazing teacher! I am so glad I found your channel

[zaqk]

I am Legend...
Paul, your lessons have added a new dimension to my life...

[polito-ydfp]

I made almost the same errors 😂😂spent about 2 HOURS decoding it in the morning, almost gave up and saw the problem in yPos, was glad to learn with you going through the same 😊

[maku]

This one was quick since I played a lot with the 3 dimensions of the sphere with the kiddos. On to the next one ! 💥

[ernestomendoza]

i did a similar mistake at first, but have it fixed before looking at the video. I am a legend!

[shatterism]

I AM LEGEND!!! Thank you Mr. Paul for teaching us the way how REAL teachers should teach ♥

[wayneswan]

Pauls having an off day today, I see. 🤣It's ok Paul, we all have our days! "were you guys screaming at me"... Yep! I was!

[pokerface]

I am Legend - I got the homework from lesson 4 to work after some struggle. I had a jail break but after doing some basic trouble shooting I discovered a typo with a small letter instead of a capital letter in a variable. Worked fine after that! Thank you.

[zoltantakacs]

Always fun when you get something moving with code. I liked the home work. Took me a few moments...but got it to work. Thank you!

[petefontana]

I am legend. I am learning so much and having fun that I stopped the Raspberry Pi lessons to devote more time to Vpython.

[PapaKn]

Great example, Paul, of debugging using "divide and conquer". I am impressed you did it so quickly and under pressure of being online! My logic was that, for any wall, the ball always has to travel LESS than the original constraints by the marbleRadius + 1/2 wallThickness., which I called adjust. The constraint then becomes : if xpos > (roomWidth/2 - adjust) or xpos < -(roomWidth/2 - adjust):. For y use roomHeight and for z use roomDepth. I am really enjoying your lessons. You are a great teacher.

[architjain]

I am LEGEND!! The best part is when you change the delta(x, y, z) and have each of them different. It actually looks like a bouncing ball! Thank you!!!!

[madsci]

I actually made a stupid mistake early on, by accidentally messing up my marble.pos vector. After doing that, I went off and made it way more complicated than it needed to be (added threads and everything). After being stumped, I started to watch the video. After I saw you start to include everything under the while loop, I realized my initial process had been correct, and returned to finally get the program working. So I only partially folded lol.
