◆ InitRender()

void iAEngine::InitRender	(	iAVec3f *	vp_corners,
		iAVec3f *	vp_delta,
		iAVec3f *	o

Initializes the renderer, by resetting line / tile counters´(=render parameters) and precalculating some values.

Prepares transformation matrix which is applied to origin and screen plane.

Parameters

vp_corners	[out] plane's corners in 3d
vp_delta	[out] plane's x and y axes' directions in 3D
o	[out] ray's origin point in world coordinates

Note: rotations and translations are inversed, because we rotating plane and origin instead of object

iAScene* iAEngine::scene ( )

inline

Get engine's scene.

Returns: pointer to scene class

◆ SetCutAABBList()

void iAEngine::SetCutAABBList ( std::vector< iAaabb * > * cutAABBList )

inline

Set pointer on list of cut AABBs.

Parameters

cutAABBList the list of cut AABB's

◆ setPositon()

void iAEngine::setPositon ( float * pos )
