The Imaginary – Official Trailer (2) (Studio Ponoc)
YouTube video by Studio Ponoc / スタジオポノック

Hello there! Have a look at the Imaginary, the latest film from studio ponoc, where I directed the 2d lighting and texturing (and also wrote the software to do it) www.youtube.com/watch?v=iQ9j...
Amazing! Great work!

Amazing! Great work!
I shared the code for the core idea last year github.com/anael-seghez...
GitHub - anael-seghezzi/SGDK_2colors: 2 colors, direct frame buffer on SEGA Megadrive/Genesis using SGDK

I agree 4 colors is the best trade-off right now. I'm not sure about interlacing yet, but 2 colors could be cool for a black and white atmospheric alone-in-the dark style adventure game. Static background, 2 or 3 characters max...

So it is possible to do 60fps 3d on the sega megadrive by using a very exotic indexing method to simulate 2 colors + alternating lines + fast DMA. Totally interlaced my brain 🙃

Cool! That's how it starts!

It's is proper 3d, but with some constraints to speed up calculations. For example, the road is always facing Z and skewing is used instead of rotation

Not directly, but I'm using tiles in a special way to simulate 4 colors to double the filling speed

Thanks! I'm hoping at least 1 rival. It's going to be hard to get both obstacles and rivals at the same time. It's easy to balance obstacles, but harder with moving elements (you never know where there will be)

Background + sprite animation (the ship is now pre-rendered) and... tunnels ! I think I can add more gameplay elements and stay at 30fps, there is hope, the megadrive is a beast :o

3D artists, show your wireframes!

Jumping! I want the driving to feel smooth and arcadey like a Sega Rally. I was never a big fan of Wipeout's physics, but I love the graphics obviously :)

It's going to be very very hard to not fall to 20fps but I'm looking at ways to precompute the player, sprites etc

Also, for the road and background, to speed up 3d clipping and projection it is always facing Z. I use skewing instead of rotation. But all transformations are 3d, and the ship is properly rotated, so it's hard to notice. The camera feels like a proper 3d camera

It's the same idea as my 1bpp demo github.com/anael-seghez.... For 2bpp you only need 2 palette entries. It's then possible to fill twice the pixels in one write but bit-masking hell to handle the tips of the scanline

Wow thanks ! :)

I reworked the camera, improved clipping and rewrote the physics with acceleration and drift, the feel is better now

Side quest in texture land... DMA is on it's knee and interrupts are eating a good chunk of CPU on #SegaMegadrive #SGDK #BlastEm

🍬🎃SUGAR GHOULS IS OUT🎃🍬
I emerge from underground to bring you a new Halloween platformer I've been working on non-stop for the last 2 weeks. It's got pumpkins, it's got goblins, but most importantly, it has GHOST KID.
So grab some candy, a controller, and have fun~
