Simple cloud layer SceneNode
Posted: Mon May 16, 2011 6:50 pm
I want to share a litte experiment with you.
I needed a shifting cloud layer in my scene and decided to encapsulate it in a scene node. Here is the result (source code and example link at the bottom of the post)
The CloudSceneNode is a dome that is spanned between the skybox and the scene
The interface of the SceneNode offers access to the geometry and the color of the SceneNode
The integration into the scene is done as usual:
For further details please have a look into the source code.
Here is a small example with the source included (build with a 1.8 svn irrlicht version) with three cloudlayers. You can turn them on or off by pressing the keys 1, 2 or 3.

Code: Select all
// returns the inner radius
virtual f32 getInnerRadius() { return InnerRadius; }
// returns the outer radius
virtual f32 getOuterRadius() { return OuterRadius; }
// returns the center height
virtual f32 getCenterHeight() { return CenterHeight; }
// returns the inner height
virtual f32 getInnerHeight() { return InnerHeight; }
// returns the outer height
virtual f32 getOuterHeight() { return OuterHeight; }
// returns the center color
virtual video::SColor& getCenterColor() { return CenterColor; }
// returns the inner color
virtual video::SColor& getInnerColor() { return InnerColor; }
// returns the outer color
virtual video::SColor& getOuterColor() { return OuterColor; }
// sets the cloud radius
virtual void setCloudRadius(
f32 innerRadius,
f32 outerRadius);
// sets the cloud height
virtual void setCloudHeight(
f32 centerHeight,
f32 innerHeight,
f32 outerHeight);
// sets the cloud colors
virtual void setCloudColor(
const video::SColor& centerColor = video::SColor(220,220,220,220),
const video::SColor& innerColor = video::SColor(180,180,180,180),
const video::SColor& outerColor = video::SColor(0,0,0,0));Code: Select all
// add 1st cloud layer
cloudLayer1 = new scene::CCloudSceneNode(smgr->getRootSceneNode(), smgr);
// set translation (speed of the clouds)
cloudLayer1->setTranslation(core::vector2d<f32>(0.008f, 0.0f));
cloudLayer1->getMaterial(0).setTexture(0, driver->getTexture("media/clouds/cloud01.png"));
// set the geometry
cloudLayer1->setCloudHeight(0.5f, 0.1f, -0.05f);Here is a small example with the source included (build with a 1.8 svn irrlicht version) with three cloudlayers. You can turn them on or off by pressing the keys 1, 2 or 3.
