this is amazing

thanks

[@calebmullan4593]

I usually get left in the dust around the 10 minute mark, but your videos are always a treat to watch. They're informative, well though out, authentic... you deserve a lot more views my friend!

[@CNLohr]

Well, these videos aren't for the views, they're for the people who know they want em.

[@araghon007]

Thanks to you I now have a strong urge to try writing an OpenVR overlay. And to try out C

[@CNLohr]

dooooeetttt

[@j0rp]

Thanks for spending the time to show that playing with something that seems complex, like VR, doesn't need to be. I frequently forget that complex != better... Been playing with making some overlays in openvr and this was really inspiring.

[@CNLohr]

Keep it simple! There's a world of beauty possible in just a few bits. I love things like demoscene for that inspiration.

[@avramitra]

I don't know how I missed your last two videos. Amazing content, as usual. Every time I see your projects, I feel motivated to push my limits and try making more complex things in C. As a result, I made a lightweight crappy gui library in C (platform agnostic, almost ) from scratch. It targeted for embedded systems. Thanks for sharing your knowledge.

[@CNLohr]

Keep going! Publish your stuff. You should probably join my discord. Lots of folks there are super into programming.

[@brayanalmonte4758]

Thank you for the video, looking forward to the current state of C video as well.

[@CNLohr]

Oh man I forgot about that one. I got mostly done with the script but I've been so out of that loop.

[@brayanalmonte4758]

@@CNLohr no worries, I didn't notice this video was 7 months old lol. Either way I always come back to the channel to see what interesting things you're working on, it's a treat.

[@milendemli]

loved the insight, would appreciate more such videos, miss the streams

[@CNLohr]

Hopefully will be doing more videos instead of streams at least for a bit.

[@adiener]

Hey, this is fantastic - I had a C/OpenVR project languishing in a nonworking state for a long time, and this video showed me exactly what I needed in order to get it up and running. Thanks for being so thorough!

[@KacperLaska]

Thank you for making this video! it is incredibly clear and to the point. Exactly what I was looking for!!!

[@CNLohr]

Thank you so much for the $$. And I'm glad you were able to make use out of it! These videos are a lot of work but I'm glad they have their payoff in people like you being helped.

[@KolibriFPV]

Real great content! I really enjoyed the speed and proficiency on you writing with C Keep up the great work!

i watch this,and i said ,you are insane!)

[@CNLohr]

I show how easy it is!

[@deltakid0]

I would prefer C over C++ even to write DirectX apps. I'm learning DirectX 7.0 hehe, also I'm learning OpenGL 1.1 because Shaders are too advanced to start with. Thank you.

[@CNLohr]

You should use rawdraw. It sets everything up for OpenGL 3.x-4.x with the shader pipeline and all for you. You can tinker with something that already works from there.

[@Bravefsj]

waiting for you new video.best wishes.

[@emagotis]

Even some prepared for excuses why you can't get started programming C in windows is shut close just after 5 minutes. 5 more minutes and you optionally get debugging in combination with a full blown IDE. 10 more he gets opengl running with textures. Another 10 and you got an overlay running via openvr in your favorite VR game. Last 10 will make the overlay even look good. Did I mention all software is free and didn't require a single registration? Welcome to 2021!

[@CNLohr]

Now, if only that comment could get posted somewhere that folks could be brought into this.

[@simracing8055]

Nope. AVRs are no longer pertinent to me. I've moved on!

I became a Windows Fanboy back in the Win3 days when I upgraded to x86 instead of my 680** Amiga. Things change. I'll die however, a 100% Linux user. On multiple Architecture Machines.

[@CNLohr]

I normally do Linux, but, for some vids I've come to understand other people really want to do Windows. If this was Linux, the first 12 minutes would have been 12 seconds.

[@mortenmoulder]

Now for the next project: A VR application to control a bunch of WS2812 in a grid. Gonna cost a pretty penny, but would be nice.

[@CNLohr]

Sounds like it'd be a lot of fun, too.

[@ligius3]

I like this and have a suggestion - maybe use a tool to show the keystrokes as some keyboard shortcuts are not obvious nor explained. Maybe you can even show coding one.

[@CNLohr]

Check out the text version of this in the description.

[@s16e559]

Thanks for the Tutorial! Would it be possible for you to also make one on creating simple drivers (for like Arduino projects) in Windows? :D

[@CNLohr]

Oh gosh. Well def not Arduino, not touching that with a 10' pole. But, something maybe like USB drivers for an STM32F042.

[@sellicott]

Just as a note, when I have a project that needs USB, I have generally found it better to try and leverage the drivers that exist on modern OS's. My personal favorite is the CDC driver (basically USB->Serial), then my PC application code can just read from the serial port.

[@s16e559]

@@CNLohr Well what I've seen in a few other projects are like serial communications, though they are handled in an driver for an OpenVR device instead of an external programm (the COM port sadly needs to be hardcoded). A tutorial with a STM32 is also really welcome! :D (maybe a small STM32 or ATmega16U2/ATmega8U2 so that those can be easily added to projects).

[@CNLohr]

@@sellicott CDC is a big problem for products. Serial ports become confusing and many extra layers of figuring out how things go together, vs using the framing USB provides where you can select a device then send/receive messages of arbitrary length.

[@CNLohr]

The ATMegaXuX is dead to me, now.

[@lofilummy8062]

i would have a look into MCXR since you seem too be a fan of Minecraft & Vr - i play on Anarchy servers it works alongside Meteor client

[@CNLohr]

I don't know how to articulate it, but I don't really care to cross those streams.

[@openroomxyz]

That's really cool, but what the efficient way to learn that things that you thoughts in the video? where did you learn all that includes and setting that you have TODO to make the thing working at the first place? Do you read documentation, guess, ask on forum, read some book about it? xD

[@CNLohr]

Just lots of googling.

[@thisfeatureisbad]

Do you think it would be possible to make a PC VR Headset from a Raspberry Pi or an Arduino?

[@L1Q]

where do I watch the modern c talk you kept teasing?

[@CNLohr]

It keeps getttting delayyyyed

[@myuniquehandle]

Unrelated to this video, but I got an idea for you. Attach VR tracking tech to an ultrasound probe and create software for composing body scans into 3D models. I think this is the next big thing in medical scanning.

[@CNLohr]

That does sound cool - but harder than anything I'd be able to do.

[@khiemng2409]

Hi Charles, you and your videos are so great. I am trying to use a VR set to get tracking information for my project (not for game). I find that I can use OpenVR for implementing that. Could you can make a tutorial video for how to get tracking information (position and orientation)?

[@CNLohr]

It is almost exactly the same as this video here. Just instead of an Overlay type, be a Utility type. There are functions for getting locations.

[@macyler]

printf("Hello KZbin ");

[@radnukespeoplesminds]

For some reason i thought you always used linux in your videos. I guess i remembered wrong

[@radoslawk6872]

He was using Mint Mate. I guess that he used Windows just to show newbies that this is possible as well.

[@CNLohr]

@Abll Rox This is correct. I do use Windows for work frequently, but for recreational coding I use Linux. I find it much easier to work quickly in Linux.

[@unevenprankster]

The TCC+NP++ install seemed to be a bit redudant after you got GCC+VSC up and running hah.

[@CNLohr]

Redundant? No. Preferred. I normally develop in TCC+NP++, I just find it easier to use than VS Code.

[@unevenprankster]

@@CNLohr Does TCC's debugging do well though? :0

[@CNLohr]

@@unevenprankster printf is the best debugging, or writing to a file so you can see what's going on. Normal debuggers back you into a local maximum of a corner and make debugging bigger problems much more difficult. Vs. if you just use printf debugging from the beginning, I find I'm a lot better off.

[@snijkwodd]

Can you do a video of getting vulkan or opengl working with vscode and mingw

[@snijkwodd]

in c ofcourse :)

[@CNLohr]

This is already in OpenGL. You can just #include rawdra_sf and you get an OpenGL Context automatically.

[@Kabodanki]

So you are not using an IDE because it shows you valid errors ? How annoying is that

[@CNLohr]

IDEs just get in the way, and generally slow down iteration times.
