Function Documentation

void VuoRenderedLayers_applyTransforms	(	VuoRenderedLayers	renderedLayers,
		VuoList_VuoSceneObject	ancestorObjects,
		VuoSceneObject	targetObject,
		VuoPoint3d *	layerCenter3d,
		VuoPoint3d	layerCorners3d[4]
	)

Apply a list of sceneobject transforms in reverse order, taking into account realSize objects.

bool VuoRenderedLayers_getLayerCorners	(	const VuoSceneObject	targetObject,
		VuoPoint3d	layerCorners3d[4]
	)

Returns a set of 4 points representing the corners of targetObject.

If targetObject is a quad, this will be the vertex positions. If targetObject does not have a mesh (or is not a quad) no points are returned.

bool VuoRenderedLayers_getRectRecursive	(	VuoRenderedLayers	renderedLayers,
		float	compositeMatrix[16],
		VuoSceneObject	targetObject,
		VuoRectangle *	rect,
		bool	rectIsInitialized
	)

Helper for VuoRenderedLayers_getRect.

bool VuoRenderedLayers_getTransformedLayer2	(	VuoRenderedLayers	renderedLayers,
		float	localToWorldMatrix[16],
		VuoSceneObject	targetObject,
		VuoPoint2d *	layerCenter,
		VuoPoint2d	layerCorners[4]
	)

Forward declaration of private getTransformedLayer function.

Outputs the center and corner points of the layer.

localToWorldMatrix should be composite all ancestor transforms and targetObject.transform.

bool VuoRenderedLayers_isPointInLayerRecursive	(	VuoRenderedLayers	renderedLayers,
		float	compositeMatrix[16],
		VuoSceneObject	targetObject,
		VuoPoint2d	point
	)

Is point in this object, or any of it's children?
