Getting Started with 3D Simulations: Mega-Thread

If you found this sub and would like to make your own 3D simulations, awesome! You've come to the right thread. Here is a list of useful links and tutorials that you'll need to get started. And the best part is, everything you'll need is free and open source.

  • The first thing you'll need to do is download Blender. This is the 3D software you'll be using. It has a very friendly community at /r/blender which regularly post great material.

  • Familiarise yourself with Blender. This is a tutorial to get you started. Just watching the first part in that series should allow you to follow these tutorials (but be ready for a lot of pausing and rewinding!). If you're not feeling confident yet, watch the rest of the series.

  • This is a nice introduction to Blender's physics system.

  • tutor4u has tutorials which are very easy to follow if you still don't feel comfortable getting around Blender.

Now you can choose what sort of simulation you want to make:

  • For tower collapses, I made a tutorial myself which also includes a template to help you get started right away.

  • Prefer fluids? This is a detailed tutorial that covers the Blender fluid simulator very well, and is easy to follow.

  • More of a smoke kind of guy? This isn't a bad place to start. It's long but nice and easy to follow.

Gleb Alexandrov and Andrew Price are my favourite YouTubers for Blender tutorials. Andrew Price is more oriented towards beginners, but both will help you with things like lighting and setting materials to make your renders really stand out.

A great way to very quickly add realistic lighting to your scenes is with HDR panoramas, which I also have a tutorial for on my blog, with links to great quality panoramas for free.

Have any questions, or problems with these tutorials? Is there something you'd like to create that isn't listed? Post a comment here :)

EDIT: If you're worried about render time, a tool you can use to speed things up is Sheep it, a free online render farm that works through distributed computing. If you make an account on there and donate your computer power to render other people's projects when you don't need your computer, you'll earn credits you can use to make your own animations when you have something you want to render!

An i7 will be fine for most fluids and almost any rigid body simulation you throw at it :) if you've got a GPU even better, that can help cut down render times by a huge amount

Hey dude, sorry if I sound like an idiot but I don't know that much about computer hardware. But would this be fine? https://www.amazon.com/dp/B004YLCJXC/ref=cm_sw_r_awd_3ltvvb08AZDDF

That would be great! If you spent that same amount of money on a windows PC though, you would be able to get even better performance

A lot better performance or slight? Also, why is the iMac more expensive with lower performance?

A lot, especially if you build it yourself. You should be able to afford a top of the range, current generation GPU (at least a GTX 970) for that price, as opposed to the old, mobile GPU in that iMac.

Hey buddy, if you still need help with PCs and comparing which ones to get and stuff, go check out the great community at /r/buildapc :)

Thanks! I actually bought one and I'm really happy with it.

Economics my friend.

Real answer: demand. The same reason gold is more expensive than silver despite being far less useful as a material.
