Hydrax 0.5 released!

The new 0.5 version is now avaible!

P.D.: I'm going to update wiki and forum with information about the new 0.5 version features this weekend

Compiles first go! Woohoooo

You might want to update the part of the Wiki about "this forum thread". It still points to:

Awesome! Thanks a lot xavi! Very good work, as usual. I will implement it into my engine sometime today.

Cheers

Working fine here, I get 100+ fps on winxp x64 and an 8800gt at 1920x1200

Seriously? What CPU have you got? I only get about 55fps in the demo, On an 8800GTS640MB at only 1280x1024.

Good!

Still c::b isn't compiling . But now appears one error .

There's one thing I'd like to suggest for the >=0.6 roadmap...

Try going underwater and positioning the camera so a tree is directly between the camera and the sun. The sun glare goes through everything and it is most apparent when you do something like this.
I'm not sure if this is something you'd want to factor into Hydrax or something developers using your library should worry about on a case-by-case basis, just thought it's worth mentioning as it's the only thing which stands out as being less than exemplary.

@FerretallicA
You can enable the god rays object intersections option, just use: GodRaysManager::setObjectIntersectionsEnabled(...), this render a little depth map using the god rays frustum and uses the information to check if the god ray is intersected by an object.
As same as with Hydrax depth technique, you've to add the god rays depth technique to all object that aren't Ogre::Entity, [GodRaysManager::addDepthTechnique(...)]

I just ran it again just to make sure. I get between 83 fps (when moving around while looking directly at all the palms and the island) and 112 fps with about 100 being the norm. I don't have any fsaa activated. I have an intel dualcore with 3 ghz (E8400) and 4gb of DDR2-800, the 8800gt has 512mb.

Congratulations!
You have worked hard!!
if the Hydrax is managed by SVN, e.g ,positioned in sf.net or code.google.com, that is easy updating.

Good!

I, too, am having this problem.

I'm using Ogre SDK 1.6.0, getting the error above, as well the Code::Blocks project includes Structs.cpp and Structs.h, neither of which are included in the Hydrax download.

Compiling the Hydrax DLL generates a libHydrax.a, but no Hydrax.dll to be found due to the linker error above.

Any help is appreciated!

I'd say you need to put
const Ogre::String Ogre::StringUtil::BLANK = "";
into one of your cpp files (as a global variable). Does not matter which cpp file, but do it only once (only in one cpp file).

const Ogre::String Ogre::StringUtil::BLANK = "";
into one of your cpp files (as a global variable). Does not matter which cpp file, but do it only once (only in one cpp file).

I added the following lines (as the linker complained about both) into Hydrax.cpp:
const Ogre::String Ogre::StringUtil::BLANK = "";
const Ogre::Vector3 Ogre::Vector3::UNIT_Z;

Compiled fine, and linked as per below; Hydrax.dll was NOT generated (libHydrax.a was generated).

Further adventures...

@okokart6 dude, This is a serious community. Go place ur bullshite ads somewhere else.

i'm having this problem too. could anyone who knows more about linking etcetera help me? i'd appreciate it a lot!
