Member Function Documentation

virtual const char* vl::MorphingActor::className

(

)

[inline, virtual]

Returns the name of the class.

Reimplemented from vl::Actor.

void MorphingActor::init

(

ResourceDatabase *

res_db )

Initializes a MorphingActor from a ResourceDatabase.

The given ResourceDatabase must contain a Geometry with all the desired DrawCalls and vertex attributes setup with the exception of the vertex position array and vertex normal array since they are automatically generated in realtime time during the rendering from the vertex and normal frames specified below. In addition ResourceDatabase must contain:

• N ArrayFVec3 objects named 'vertex_frame' containing the vertex position for every frame
• N ArrayFVec3 objects named 'normal_frame' containing the vertex normal for every frame where N is the number of animation frames.

void MorphingActor::blendFrames	(	int	a,
		int	b,
		float	t
	)

void MorphingActor::update	(	int	,
		Camera *	,
		Real
	)		[virtual]

Virtual function used to update or animate an Actor during the rendering.

Parameters:

lod	the LOD (level of detail) currently selected for the rendering.
camera	the camera used for the current rendering.
cur_t	the current animation time.

Note:

• is called after the actor resulted to be visible
• is called only once per frame
• is called before setting up the rendering states
