3D Sky - Tech Demo(Sega Genesis)

[ud2hb4]

wow...it's so smooth

[weirdal27]

Yo you like Mode-7? Well we're got MODE-8! Sega DOES what NintenDON'T

[RottenRroses]

It reminds me of Sonic 2.

[killkenny5000]

@RottenRroses it reminds me of sonic CD :)

[zecle]

sonic 3d special stages.

[haxor758]

The graphics are better than Crysis

[haloalldaylo]

feez mode 7!! sega genesis baby!

[layzergun]

Mode 7 on the sega genesis? Genesis does what nintendoes too!

[jimmyjimbo72]

How exactly are you doing this? Its just that the Mega Drive itself couldn't perform sprite transformation, only the Mega CD and 32x could.

[tonmasboy]

@jimmyjimbo72 mega drive could perform this but is unusually set its benchmark with bit things

[Ehal256]

@jimmyjimbo72 It can, but only in software, meaning it's probably pretty darn slow.

[schnappy00]

I can think of a better example - Doom 1 and Doom 2. It's incredibly effective :)

[katakisLives]

This would have looked great in a game like Afterburner.

[Plastiware]

I would have freaked out if the camera rotated. Otherwise it's rather unimpressive.

[lemurboy12]

Mode 7 on a Genesis?

[Anayo]

That's what I was thinking.

[3yE]

Hold it! It's just per-line colourcycling trick! I.e. you have a texture 16 pixels wide, pre-render a projection to a pic and encode the U texcoord as colour of pic. Then you prepare 16 palettes, one for each V coord, which encode equality between U and colour. Then you just have to do 1 raycast per line to determine the V coordinate you hit and substitute the palette in the line interrupt!!!

This effect is highly limited. You can add horizontal scrolling but no different tiles, etc.

[SyriusBelsferg]

Pardon my ignorance... but what does that mean in layman's terms?

[coltermegasxlr]

Hi, this maybe off topic, but do you have any idea how they managed to pull off the amazing graphics in the genesis game "Panorama Cotton" ?

[Xeniczone]

Can't be Mode 7, because the Genesis can't rotate or skew sprites. The Sega CD and Sega 32X added these functions. For example Sonic CD special stages.

[alucard1931]

It could possibly be added via a special processing chip thru the cartridge, the way Sega was able to pull off rendering polygons in the Genesis version of Virtua Racer.

[GGigabiteM]

@alucard1931

The chip in Virtua Racing was a full blown CPU. It basically rendered the environment in software and converted each frame to 16x16 tiles and used DMA to transfer the tiles to VDP memory to be displayed on the screen.

You could do almost any effect in this method, it's just slow, uses tons of bandwidth and is limited to 64 colors on the screen.

[alucard1931]

I forgot that the chip itself was a CPU in the cart. I remember Nintendo pulling off that same task with the original StarFox.

[GGigabiteM]

@alucard1931

The Super FX chip is different in the SNES as the SNES has a frame buffer where the genesis doesn't. As such, the Super FX chip is more efficient because it doesn't have the extra step of converting each frame to a tile map to DMA to the genesis VDP.

[alucard1931]

@GGigabiteM I remember the SNES getting a port of Doom, and the Genesis getting a severel watered down Duke Nukem 3d. For all their faults (being cost size and resources), carts did have a slight advantage in actually adding to the existing console's hardware. It didn't matter anyway, because the "16-bit" era was nearing its end, and the PSX/N64 era was on the horizon.

[sonikku956]

@Xeniczone uh, thats 3d...

[Xeniczone]

@sonikku956 Well, it looks 3D, but it's really an ingenious way of controlling sprites. By taking a sprite, like this cloud sprite, and by skewing it and rotating it, it will look like a 3d.

Like I said the best example I can think of is Sonic CD special stages.

[dairyduck]

@Xeniczone alot of old DOS games did that, like Outlaws

[yarimarbitch]

@dairyduck I enjoyed outlaws back in the days. funny times then.

[TheMVRules]

Imagine if they made 3D Blast like this. It would be amazing!

[estlib]

imagine if this guy would make a proper doom port for GENESIS not like that 32x abdomination

[lightdark28]

that shows you that the Mega Drive/Genesis, while worse on paper was capable of a lot more than was typically seen on it.

dreamcast was the same (weaker than PS2 but the graphics were the same, or better

[richardbirch2007]

damn right. Metropolis Street Racer on the DC is downright awesome! Still play it on nullDC today

[Technocian]

Basically mode 7. Trading Vertical movement for Depth.

[FiasaPower]

Mode 7 ? System-16 (Genesis-based hardware) can did this when Mode 7 wasn't in project table ...

[flygonbreloom]

Well done imitation of Mode-7

[hilarioph]

Amazing

[Outlander11]

keep up the 68k work!

[Christuserloeser]

GREAT!

[tinctu]

Look at that speed... NICE!!!

[8bitwiz]

Translation: "3D scroll #2. This time we try flying over the clouds."

P.S. すごい！

[KaskelotenZebbe]

Sorry for not knowing Japanese, but I find your videos very awesome. Are you going to use this for a game of your own?
