addDirectionalLight()

size_t ShadowRenderer::addDirectionalLight

Here is the caller graph for this function:

addNodeToShadowList()

void ShadowRenderer::addNodeToShadowList	(	scene::ISceneNode *	node,
		E_SHADOW_MODE	shadowMode = ESM_BOTH
	)

Adds a shadow to the scene node.

The shadow mode can be ESM_BOTH, or ESM_RECEIVE. ESM_BOTH casts and receives shadows ESM_RECEIVE only receives but does not cast shadows.
