how to use
firstly create the jungle node. this node require a terrain scene node for height reference.
Code: Select all
// create jungle.
// terrain texture is 256 x 256 scaled by 40.0
// lets create density of one tree every 8x8 pixel
jungleScene::Jungle *jungle =
new jungleScene::Jungle(
10240, // world size
8,// chunk size. "chunk size" * "chunk size" = "tree count per chunk"
16,// max tree dimension diameter
4,// tree circular detail
terrain,
smgr,
-1);
smgr->getRootSceneNode()->addChild(jungle);
jungle->getMaterial(0).setFlag(EMF_LIGHTING, false);
//jungle->getMaterial(0).setFlag(EMF_BACK_FACE_CULLING, false);
jungle->getMaterial(0).setTexture(0, driver->getTexture("./media/bark.png"));
jungle->getMaterial(0).MaterialType = EMT_SOLID;
jungle->getMaterial(1).setFlag(EMF_LIGHTING, false);
jungle->getMaterial(1).setFlag(EMF_BACK_FACE_CULLING, false);
jungle->getMaterial(1).setTexture(0,driver->getTexture("./media/leaf.png"));
jungle->getMaterial(1).MaterialType = EMT_TRANSPARENT_ALPHA_CHANNEL_REF;
create a tree. for easier usage, a tree struct can be create to store all configuration. maybe a json file next time. pay attention on the last parameter. you can create a tree with "instant grow" means it suddenly mature and tall, or "growing slowly".
Code: Select all
jungle->addTreeAt(core::vector3df(cx, terrain->getHeight(cx,cy), cy),
16,// segment count per branch, the more the better curve
5,// min rotation allowed
30,// max rotation allowed
800.0f, // length
2, // branching count, how many branch may appear from single trunk
7.5f, // max radius, the widest radius
3, // ground root, max number of ground root.
200.0f, // leaf width. maximum leaf dimension
200.0f, // leaf height. maximum leaf dimension
2, // leaf segments, number of leaf segment (for now not working yet, just use 2, reserved for palm trees)
1.0, // leaf stiffness (not working for now, reserved to generate palm trees)
0, //leaf type, this is leaf texture selector, for now 0-7, next release user defined
0, // bark type, this is bark texture selector, for now 0-7, next release user defined
seed, // seed, random seed, integer value to make every tree unique
true // instant grow or use animated growing, bad if the chunk are too large since an update at a chunk means an update to whole tree collection in it.

. infinite amount of tree types, possible to define as many as possible tree settings, infinite amount of texture variation, for now 8, i'm planning to make this user defined, each texture split to 8 horizontally. and the generator pick one using uv coordinate. this way each chunk drawn using only 2 materials. 
. trying to generate tangent for the trees, for lighting. i can not promise any release soon, just tying to be productive in both producing and learning, perhaps next month.
