3D Object Rendering Using an FPGA

- Rendering 3D models is an often slow and computationally expensive task. However, with the hardware customization and reprogrammable flexibility of FPGAs, this performance can be improved.
With that in mind, Surbhika decided to build customized hardware on an FPGA to render 3D objects into images and display those rendered images on a monitor over VGA. She's used Verilog for the hardware implementation so that the code can be easily compiled for most FPGAs on the market. Happy rendering! bit.ly/3RhV601

We'll hold our hands up and admit for this one, the audio was as good as we could make it with a fan keeping the presenter cool :) Thanks for watching and your patience, turning on closed captions may help your experience with this one!
i assumed wind noise when I saw her hair blowing. Personally, I would have preferred hear some wind noise and less noise cancellation effects.
I look forward to more videos from this presenter. This was amazing
3D rendering and a DE0-Nano. Now that's my kind of video! Great job on this.
Very interesting. I studied computer graphics a few decades ago. This is a great update. Pity the audio was so low quality. It was as if the volume kept fluctuating and also the pitch.
Element 14 get this wonderful presenter a decent microphone. This is a quality video!
That was a lot of work! Well done. Way above my technical ability but managed to follow you. And for all of those who are complaining about the accent, use subtitles. its not that hard. Sheesh.
It's very glad to see your tutorial videos in the element 14 channel , we got a Indian electronics content maker
Yes, indeed Please explain the VGA Pixel block.
I will try it on my Virtex 6 board
two triangles at 20x20...did I miss something?
I did a 3D rotating cube on an arduino uno maybe 15yrs ago
Pretty amazing that something like this is indeed possible with an FPGA. Maybe there’s an Extended Ram Shield for this? 😉
Great insight and technical expertise. Well explained. Kudos !
This video is educative and inspiring. It makes me really want to buy a FPGA board and learn how to develop in Verilog. Thanks for your great work!
Thank you, great video. I have a DE0 Nano and it is great to see it in this application. I assume the VGA output is TTL levels or is there an external DAC. Would love to see the circuit and IP you used. Thanks 🙂
This was surely a lot of work, very impressive.
It was indeed! :)
@@thepeppertech how much? 5 years?
Great project!!...Very well explained.
I'm very fond of graphics. This video gave me good insights about the underlying concepts of rendering.
Thank you!!
Which development board you are using?
so the data of the mesh was encoding inside the FPGA? how hard it would be to feed it from a ROM chip? also, you could skip the trigonometry if you also hardcoded the ViewProjection matrix, or directly store the mesh in screen coordinates. Very interesting project.
The mesh data is encoded in the ROM implemented in FPGA. If you wish to feed it from external hardware then you will need to implement interfacing part only. The ultimate goal is to pipeline the whole process.
@@thepeppertech Thanks
Thanks ! Very informative and help5
20 by 20 pixels… alright then
Very impressive and well presented. Have you tried reaching out to Intel to see if they could provide a more capable FPGA to help continue your project? I'd love to see a follow-up!
So it is a primitive form of rendering engine ??
Thanks a lot for sharing.
Can you also make a video on speech synthesis & recognition on FPGA for understanding the algorithms? Or perhaps a soft core.
ALSO, another video on FFT implementation of FPGA with detailed explanation
Thanks
Cheers ✨✨

Interesting. :o
Bazinga!
great， i like fpgas
One more question,
1] for SIne and cosine, why do you use Lookup memory in contrast to Cordic Block ?? In fact, the Cordic block would have worked faster.
2] Is the buffer used, a dual-port memory or just simple registers?
1) I believe it's for performance
2) I don't know
Used LUT because aim was to develop simple and fast hardware. Cordic algorithm is great for higher precision. And the buffer used in this implementation is simply a set of registers.
Cool content 😮
You are beautiful 👌👌😘
I'm from Tamil Nadu...!!
The audio was horrible and difficult to hear clearly. Whatever was done to the equalization and compression did not work.
It was very warm in the workshop for the presenter, we had to edit out the fan noise in post, it should be better in future :) Thanks for watching!
Well that was a massive letdown, I expected to see a car model 3D rendered and all you could fit on the fpga was a single triangle? Surely you could of at least done a cube, It’s only eight vertices and twelve triangles but my real question is why do this anyway, GPUs are designed for this.
Implementation on FPGA gives two advantages: (1) build customised hardware with performance in direction of ASIC (obviously lesser than that) but more than a general purpose GPU (2) we get to DIY cool concepts and know “behind the scenes” of rendering process.
Hi, nice work! Check out my project of rendering 3D solid meshes using FPGA.
Like a typical Indian can say
Samjh nahi aya but sunkar Achcha laga
What language is it?
VERILOG. It is a widely used Hardware Description Language (HDL) :)
I grew up in the Washington DC area and am pretty used to accents, but this accent is pretty thick and I have a little bit of a hard time following her
Imagine a German trying to understand it.
i live in jersey so this was easy listening honestly. the closed captions are 98% accurate
you people don't automatically turn on closed captions? I do it without even thinking anymore, this particular video has a dedicated English subtitle file
It wasn’t her accent, I think, there was either some clipping, or very aggressive noise reduction. I’m very good with accents, and still had to really concentrate.
@@Hacker-at-Large Yes there was something very odd going on with the audio, it seemed to get a bit better toward the end, but at the start there are all sorts of weird effects going on. This was very apparent when the mid point DC to Daylight advert came on, the audio quality was way better than the main video.
The subtitles are good, but anoither tip i.s to slow the playback down slightly that make a big difference is some cases, but here it's the audio quality more than anything else causing the problems.

Audio is terrible.
use closed captions
Couldn’t understand a single word. What a mess.
use closed captions
