Myrddin Landscape PLugin and Editor

myrddinson · Post by **myrddinson** » Mon Mar 31, 2008 2:54 pm

Hi,

i am currently working on a paging landscape plugin (and editor).
Currently, plugin development is at 80% and these features are implemented yet:

// terrain splatting (up to 8 layers - 3 layers per pass),

// lightmap : color added to ambient color,

// color map : color modulated with diffuse color

// specular lightning (per layer specular color or specular color map),

// optional per-layer diffuse and specular color,

// normal mapping,

// offset/parallax mapping,

// point/directional/spot light (one per pass)

// fog

// shadow map

// LOD geomorphing

// optional slope/ground autosplatting

// water plane(s) (refraction/reflection, sky and sun reflection, deep sea fog)

// smooth range interpolation from full effects to low effects

// paging

i still need to implement streaming paging, complete runtime generation of shaders and vegetation.

This plugin will be used by the MOgre-based Myrddin landscape editor that is in early development (20%)

For now, I intend to release the plugin under LGPL license but the editor will be sold separatly under shareware license.

Sorry i have only screenshots for now: i will release a demo soon

Is the plugin for Mogre only? I hope not. There's too many nice features to miss if it is...

BTW, the links to the images seem to be broken. None works here. Downloading works fine, though.

the landscape plugin is written in C++ and so fully compatible with Ogre:
i use SceneManager::setOption from the MOgre-based editor to control plugin features (as well as editing) because i wanted to keep Ogre plugin architecture to avoid porting plugin in .NET.

I don't know for the screenshots: they seem to be well displayed for me sorry.

the screenshots are not visible

ok perhaps it is because screenshots are on Free (french provider) server and only accessible to Free members: i will fix that as soon as i can.
Sorry for the inconvenience

So here are the screenshots with functional links - i hope so

but is this faster than PLSM? PLSM is very slow, so I would like to see faster terrain manager =) And I will also be glad to test it =)

currently, framerate with the small landscape showed in the screenshots is about 180fps on my computer system - Intel Core2 duo 6400 2Go RAM and Geforce 7950GT.

I have not tested yet on a ATI based system: i would be glad to know about reporting bugs if any.

Nice shots, I've worked some time ago on a parallax mapping texture mode for PLSM2 that looks similar to your work(Only the appearence!) there's the link: http://www.ogre3d.org/phpBB2addons/viewtopic.php?t=5441

Very good work, can't wait to try it!

I am building a small demo now but i need to deal with some right troubles: i 'borrowed' textures that i use in the screenshots in Neverwinter Night 2 so i need to replace them with free ones but it is difficult to find good free textures - with normal map (and normal+heightmap for the dirt road)

so perhaps i will release the demo without normal maps.

There's a very useful and easy phosothop plugin for generate normal maps of any texture:

I use this for generate my terrain normal maps.

You can get nice free textures in: www.cgtextures.com

and you can make nice bump/normal/specular textures of them with: www.crazybump.com

cheers!

impressive screenies, definately looking forward to try it out

Seregvan · Post by **Seregvan** » Mon Mar 31, 2008 9:58 pm

+1 =) want to see it working =)

Nice shoots. Do you want to combine it with paged geometry?

How does the splatting work? Shaderbased v1.1, v2 or v3?

Looking quite awesome, and just at the right time for my little project!
Does it have support for heightmap based terrain?

Looks nice

yes plugin has support for paging geometry: i still need to implement async streaming but sync paging is working yet.

splatting (and water) is vs20+/ps20+ arbvp1/arbfp1 shader-based: for now - and in the demo i will release soon -, i use multiple lod techniques and preprocessor defines to deal with level of detail but i will implement shader generation at runtime soon because it is the only way to optimize shaders for a given set of material settings, especially too when you want to optimize shader on a per-tile basis (some terrain tiles can use less or more textures depending on the per-tile splatting layer usage)

thanks for the nvidia tools: i am currently playing with it:)
finally i will be able to release a demo with free normal mapped textures...

I will release a demo of the Myrddin Landscape plugin in a couple of days now: here are some new screenshots.

Oh my god, so juicy. I scrolled through those screenshots with wide eyes.

Seregvan · Post by **Seregvan** » Fri Apr 04, 2008 9:29 pm

Yeah, it looks very nice ) but i think you should post only small copies of your screenshots and give a links to the big ones =)

Very nice.

deficite · Post by **deficite** » Sat Apr 05, 2008 12:10 am

^ that's my favorite one. I love the depth that the terrain has and the lighting is cool (although weird, unless the planet exists in a binary star system).

myrddinson · Post by **myrddinson** » Sat Apr 05, 2008 1:32 pm

No there is only one directional light and lighting seems right for me

Can you explain what is the wrong thing ? Perhaps you are speaking about specular reflection on the rock: i have raised the material specular color to enhance the specular effect and indeed specular reflection can be confused with a second light reflection...
