Python 3D Graphics Tutorial 3: Designing 3D Models with Parameters

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 parameterize your 3D models and animations in vpython (Visual Python, and how to create your first three dimensional models. I do not assume you are an expert, so these lessons are designed for complete beginners.

I grasped the concept perfectly. So much so that I paused the tutorial half way through and replaced the positions with parameters, played with the size of the room and parametrised the bouncing equation to make the edge of ball hit the wall. I did the homework before I got to that part of the lesson!! You are the best teacher that I ever had.

[undeadpresident]

You are a really good teacher. The only one I've yet seen who has explained coding in a manner that makes sense to me.

[opalprestonshirley]

When you look at the numbers by themselves it is just numbers but with a name so much easier to visualize. Thanks again, Paul.

I am legend! I replaced the models with parameters without needing to watch the video! It reminds me allot of Fusion 360's model parameters, which made it much easier to figure out! y a y !

[peterhartshauser]

It's like your are reading minds. Your two video this week were just perfect and on point. Thanks!

I created a parametrization to velocity sphere

velocityRateBall = 10
rate(velocityRateBall)

Thanks again, Paul!

Did the homework even before you gave it. I was annoyed how it would bounce relative to the center and not the edge of the all, so I fixed it before the lesson and that turned out to be the homework!

I paused the video and parameterized the wall thickness, room height, room width and room depth before I saw you do it. Before I ran it for the first time, I set the height, width and depth to different values so that I would know whether I had put the parameters in the wrong place. Setting them all to 10 made it too easy to make a mistake. I am legend. PS Jolly good tutorial!

Legend. This was a fantastic lesson. I was hit with another problem today of a cuboids permutations and this was SUPER helpful in creating a visual representation of that. Your Fusion 360 vids also made this lesson more approachable. Best engineer teacher on YouTube.

[cbrombaugh]

I AM LEGEND! Adjusted for marble radius and wall thickness. At least it looks good on the screen. Thanks for the most excellent lessons Paul!

[pokerface]

The parameters make a lot of sense, and it makes it so easy to adjust anything when the parameters are named logically. Thank you!

[prensesbanuu]

good job old man. i admire your hard working

[hughpatterson]

I declare as many variables as possible (and realistically practical) and I cannot stress that students use variables to save time. This great lesson really drives home this point and will be required viewing in my class. Thanks again for another great lesson, Paul!

[amayaphotos]

This was a very good lesson and yes i am legend...i was able to do the homework
Thank you Mr.Paul for all your tutorials and lessons. Your stuff are amazing and I wish that every teacher could be like you and thank you once again I'm just a 14 year old kid who is really enjoying your lessons.

[syedmurtazajaffar]

You are an awesome teacher...Bless you...

[alberthilmennstein]

I really appreciate your work Paul, people like you will change the world and bring geniuses to us . Thanks mate !

[Vbeck]

This is just like Cutter Comp in CNC langue, when you asked to change to sizes in the Py code I had added them as parameters. (I draw that way in Fusion360) and I added wall thinkness to the roomWidth and roomHeights. I was delighted when I realized that since the origin of the walls is at the center, I didn't need to cut the wall offset in Great Lesson !!!

[johnplowright]

Had a play with the moving ball to make it go diagonally and change at the start of the ball, pretty cool and the size vector does make it all easier to think about the space.

[codecage]

Great video and a super easy method to follow about parameterizing the code! There are Legends amongst us!!

[alfredcalleja]

Another great tutorial full of great, informative concepts: thanks once more!
