My pleasure :)

Glad you enjoyed :P did you give it a try?

@@EngineerNick not yet, i cant use my pc right now, but once I am able to i definitely would give it a try 👍

D: ok thats good to know but please be careful! lol

Hey there :) I had to remove the chamfer operation from some of the sharper corners.

ooo uvs are a fascinating idea! I hadn't thought of it. It would be hard though you would need to generate contours/isolines using marching squares in uv space, reproject them into 3d then apply this knit method. Marching squares seems feasible though with recent versions... perhaps i will try it

Hi Vivek :) Apologies i seem to have lost that repo somewhere on an old machine. You wont be surprised that i never really made any progress on that ECS after getting distracted with typescript :p

Thanks for your kind words i am so glad you enjoyed it :)

Hi Mark :) I used HCl pool acid, nothing special

@@EngineerNick thanks mate

Hi Broccoli sorry about that, there is a hard trade-off between audience attention and going into background info. I'll try to keep things at 1x speed in future :)

Hey blueberry :) I know the second half was a bit hard to follow, was it the bit with the sphere?

Thanks for the comment, glad you got it working. i will have to actually try apl one of these days :)

By the way, my lines run from [0, 0, 0] to [10, 10, 0] and from [10, 0, 0] to [0, 10, 0]. I therefore expect an intersection on [5, 5, 0].

I just realized that my t is a vector whereas in your original formula it was a scalar. However in your video you refer to the cross product? How did you mean this?

Hi Woudjee! In 3 dimensions there is actually a much nicer way; rather than calculating the exact intersection point you can find the shortest line between the segments as described somewhere on this page paulbourke.net/geometry/pointlineplane/; if the length is zero then you have an intersection. Regarding the 2d cross product, i define it in the video. it is the magnitude of the 3d cross product assuming the z component is zero. It is not really a cross product in 2d; but it shares many of the same properties.

@@EngineerNick thank you for your reply! Will check it out this week :D

Same url engineernick.com it just doesnt have as many interesting toys :)

Ah damn yeah I didnt really have animation in mind for my use-case. Hopefully in newer version of blender it will have better performance and be more stable :)

hey are you using Blender Geometry Nodes for creating knitting patters for clothes ?

Hi Ryan, at the time my house was evaporative air-conditioned so there was always positive pressure and a few windows/doors open. I never had issues with the gap. I have since made a new version with less gap (sadly no video tho). Thanks for the question :)

I deleted all the default config and wrote my own tiny subset. It felt a lot easier to remember that way. I also found i had to change some stuff for the australian accent. but there is definitely a benefit to sticking with the standard.

Thank you, sir :)

I appreciate your comment very very very very much! :)

Glad you enjoyed the video, fascinated to hear what you are using it for very cool :) If i ever try it again ill look into the dye and toluene thing :)

@@EngineerNick I forgot to add that depending on the silicone you're using; mineral spirits may do the job better at thinning it. Gasoline also is an amazing thinner for it but the fumes are really dangerous!

@@EngineerNick oh I just meant in the game, though the idea of doing that for a game jam is interesting. not sure how rules would impact it, you might also have to write your own exa asm machine emulator haha. next bigger game jam I’m aware of is Ludum Dare 54 - September 29th - October 2nd, 2023.

you could probably just put a curve to mesh at the beginning then a mesh to curve at the end

Hi Waqas :) Both ACxCD and t are scalar. Please see 3:33 where I briefly define the '2d cross product`. All the best on your line segment journeys! :)

@@EngineerNick I have lots of respect for those who propagate knowledge. However, re-inventing the existing mathematical terms is not a good idea. cross product of two vectors is always a vector. plz correct me if i m wrong somewhere.!

Normally it is only defined in 3D where the result is a vector. Here we assume the Z component is zero, do the calculation anyway, and simply take the magnitude of the result which is scalar. Many of the interesting properties still work, for example the magnitude is still the area of a parallelogram defined by the inputs. This operation does exist in 2d by other names; i think i recall it is related to the wedge product and possibly the inner product, i havent checked today. but honestly i find those concepts less useful. it is fairly common in computer graphics to define a 2d cross product this way, though you will see the function with many different names when reading code.

@@EngineerNick thanks for the clarification!!

Hi Ido, thankyou for your question :) I cover this situation at 4:33 when i (sortof) explain that the matrix is not invertable when the line segments are parallel. I think a matrix is always invertable if its determinant is non zero. the ABxCD part is the determinant. Hope this helps :)

@@EngineerNick Thank you! Asked the question before I saw that part of the video. Great video! A matrix is invertible iff its determinant is not 0, yeah.

Hey there :) What IDE are you using if not VS code? Maybe my advice about the typescript language server (and setting those environment variables) might be specific to the VS Code typescript implementation? Have you added "debugger" statements and made sure that the chrome:inspect devtool thing has connected properly to the node.js instance running the typescript server? I also had trouble at first... after setting the environment variables you typically need to restart your IDE so that it reloads the environment variables. If you were using VS code I would have recommended using the extension 'Ts AST Viewer' which I discovered after making this video. It lets you interactively browse the AST of the currently opened typescript file in like a tree explorer view. It makes a huge difference when trying to understand what is going on! I am still suffering with other problems related to static functions in typescript :/ Plugins really aren't the answer. i wish typescript had Traits like in rust. And I will be checking your channel for any cycling videos after writing this ;)

Didn't figure the stuff out yet, but judging by process arguments, the LSP-typescript for Sublime Text uses different arguments for tsserver. Gonna find out how to force the args of my choice in.

Got it, just have to make sure LSP-typescript uses tsserver from the "example" dir and the port's not occupied by another instance of tsserver.

Thanks for the watch and comment Nadie :) I am glad you found it helpful! Regarding carbide powders, yes I think they are dangerous but normally the hazard arises when they are used in high speed cutting, or where sharpening carbide tools makes a fine airborne powder. I don't think this process releases any breathable dust with the possible exception of the smoke from burning the paper. Pretty sure the blender is fine... although I did indeed get in trouble for using it :P

Hi Tony, that's true but i was hoping the glue would result in better thermal contact. Probably a set screw pressing metal to metal would have been better even though it would push all contact to one side.

Hi Bawbak, please don't be discouraged :) Matrices often look more complicated than they really are. They are just a shorthand notation for multiplication and addition, The most complicated bit is the bit where the matrix is inverted so it can be moved from one side of the equation to the other. Keep learning you can do it :)
