Detailed Description

A GT_Primitive that wraps a USD Prim.

A GusdPrimWrapper is responsible for copying attribute data between USD and GT.

To write USD geometry, the following steps are taken:

The ROP uses GusdRefiner to refine the cooked geometry to GT primitive types that have a matching USD type.

For each GT primitive we create a primWrapper by calling the defineForWrite method. This will create a usd prim on the current stage.

On each frame updateFromGTPrim is called to copy attribtutes from the GT prim to the USD prim.

We support: Writing a sequence of frames from one process. Writing each frame of a sequence to a seperate file from a seperate process. Writing each frame of a sequence to a seperate file from one process.

When writing all frames to a single file, we try and compress attribtute values. The data we need to do this compression is kept in the prim wrapper.

In the rare case where we want to sequentially write a sequence to per frame files, we need the primWrapper to persist across the sequence so we can do the attribute compression. However, we need to create the USD prim on each per frame file. The "redefine" method is used for this.

To read USD geometry we start with a GusdGU_PackedUSD prim. A GusdGT_PrimCollect object has been registered to convert these prims to GT_Primitives for drawing in the view port. This object will call the "fullGT" method of the GU prim which in turn calls the "defineForRead" to create a GusdPrimWrapper. These prims can be refined into native GT_Primitives that the viewport can draw.

virtual void GusdPrimWrapper::addLeadingBookend	(	double	curFrame,
		double	startFrame
	)

virtual

Add a sample just before the current time that invises this prim. For points and instances this means writing a empty point attribute. Other prims set their visibility flag. It might be possible to avoid this if we are on the first frame.

static void GusdPrimWrapper::addReversePolygonsAttrib	(	GT_AttributeListHandle &	attrib_list,
		exint	num_elements
	)

static

Add the "usdconfigreversepolygons" attribute to record whether the winding order was reversed.

virtual void GusdPrimWrapper::addTrailingBookend ( double curFrame )

Add a sample at the current frame, invising this from.

Compute a USD transform from a Houdini transform.

houXform is the transform from world to the prim's space in Houdini. This includes the object node transformation and the transform of any containing packed prim.

xformCache is a map of the transforms of any groups that have been written on the current frame.

static

Given a USD prim, create a GusdPrimWrapper of the proper type.

When reading a USD file, we call this function to create a Gusd_GTPrimitive for each USD prim, we then refine that to something that can be used in a detail.

		const UsdStagePtr &	stage,

static

Given a GT_Primitive, create a USD prim of the proper type.

When writing a USD file, we refine the geometry to a set of prims that we can deal with then we call this method on each of those prims.
