Concept for the Sonic Xtreme PC version level editor.
We wanted to do a level editor for those of you who don't really model, something simple yet powerful.
I wont explain how it works, since its easy to make out whats going on in the pic below.


we haven't really worked on it to much.
So far we have vertex welding capabilities. which is key for geometry optimizations.
without that it would make the models a bit heavy on slower systems..

This model was done from scratch polygon by polygon, looking at pictures of SANiK's fisheye viewer as a reference.
( some of the block sizes were inconsistent with the Jade gully video that Chris Senn released)

Inconsistent images



SO.... we used the video as reference to make corrections to block scales.
( we used the texture pixels as a guide for aligning up polygons between video and model which makes everything pixel perfect)

The 2 images below show the differences wood bridge scale, waterfall foam scale, as well as waterfall and river indentations into the ground for some of the upper level areas)

I did a level edit using sonic ED and built a ( I call it U-Pike)
Ran it in emulator and noticed something odd....
Sonics Maximum height seems to be different! anyone else notice this before?
I triple checked....using slow motion. and frame by frame.



one of our physics testing areas, this layout is made up of random sections of Spring yard zone and some other random models I did awhile back.
Yes, I know.... its not pretty,,, what matters here, is that the slopes are pixel perfect to spring yard zone angles.

Concptual grass test,
we will be doing our grass similer to this example I've tossed togeather,
final grass wont be as demanding on the graphics card,

A playable demo:

Hmm. I just get a blank screen..

[MarkeyJester]

same here, I did see a small glitch of grass about 4x9 pixels big, but that's it, blank.

Would someone post a youtube video showing off the demo? I can't play it on my computer.

It's just a grass shader, not really anything special. The picture shows off everything about it.

[synchronizer]

Ah okay. I thought it was a game demo for some reason.

Try rotating the camera with the mouse( drag the mouse to the left), also arrow keys move the level around,
Its quite lazily tossed together, therefore the grass isn't visible right off the bat.
Was never meant as a presentation piece >__< sorry guys.

Also its not a shader, actual geometry is used for the grass. a shader ( which will be used later) is more performance friendly than the geometry method.
just wanted to see if we could get the grass to work as a proof of concept.



Next demo will be our fisheye engine,

Im a tad confused about what this topic is actually about. I see alot of interesting pictures of sonic levels with a 3d twist. And then I hit page 2 and see abunch random info about sonic extreme and a level editor then a grass shader. >_< so please tell me whats going on here.

Hnmm yeah,,,,, I guess that I should probably redo the intro topic a bit,
Our engine is actually A multi purpous game engine which alows a few styles of sonic games to be built.
Sonic Xtreme PC sonic Xtreme Saturn, Sonic classic 2.5D


As for the grass post,,,its single component of the engine, I thought it was cool, so I shared it.


Edit: First topic reworked.

(All image links of first post give me 404 errors)

Grass of demo is nice, but I get pretty low fps there -my PC runs most games flawlessly.

Hey What are the specs for the system your on? and reported FPS?
ya I know the grass runs pretty slow on some computers.
we will be using a shader instead of geometry, later on, just wanted to get a general idea of what it would look like.

Thx for letting me know about the 404 errors, maybe imagshack has some problems ??
I'll wait awhile to see what happens before re-uploading them.

You're welcome.


Looking at black background: around 65 FPS.
Looking at grass: around 35 FPS.

My specs: WinXP, Core2Duo 2GHz, 2GB RAM, Nvidia 8600M GT (256MB).

The problem is that there is a wordfilter on this forum, so the lowercase I always gets turned to an uppercase I, therefore breaking all your image URLs which contain an I in the path.
