Detailed Description

This class which contains a geometry with a single textured rectangle mesh. It is particularly useful in conjunction with vtHUD, for superimposing a single image on the window.

Member Function Documentation

bool vtImageSprite::Create	(	const char *	szTextureName,
		bool	bBlending = false
	)

Create a vtImageSprite.

Parameters

szTextureName	The filename of a texture image.
bBlending	Set to true for alpha-blending, which produces smooth edges on transparent textures.

bool vtImageSprite::Create	(	osg::Image *	pImage,
		bool	bBlending = false
	)

Create a vtImageSprite.

Parameters

pImage	A texture image.
bBlending	Set to true for alpha-blending, which produces smooth edges on transparent textures.

void vtImageSprite::SetImage

(

osg::Image *

pImage

)

Set (replace) the image on a sprite that has already been created.

void vtImageSprite::SetPosition	(	float	l,
		float	t,
		float	r,
		float	b,
		float	rot = 0.0f
	)

Set the XY position of the sprite. These are in world coordinates, unless this sprite is the child of a vtHUD, in which case they are pixel coordinates measured from the lower-left corner of the window.

Parameters

l	Left.
t	Top.
r	Right.
b	Bottom.
rot	Rotation in radians.
