Detailed Description

Class used for rendering point cloud data into a raster tile.

It is derived from ossimImageHandler so that it can be included in the available file formats for reading as maintained by the ossimImageHandlerRegistry. This base class implementation exposes the data elements represented by the base-class ossimPointCloudSource and the individual point base-class ossimPointCloudRecord, namely, intensity, RGB color, elevation, and number of returns.

For sensor systems providing additional renderable data items, a derived class will be required to expose those components.

getEntryList()

void ossimPointCloudImageHandler::getEntryList ( std::vector< ossim_uint32 > &  entryList ) const

overridevirtual

Gets entry list.

This list reflects the data component entry list provided by the derived point-cloud handler. This base class understands the basic (LIDAR-biased) entries: "Intensity", "RGB", "Elevation", and "Return". If a sensor provides other components, then a derived image handler will be needed to rasterize that data channel as well.

Parameters

entryList

This is the list to initialize with entry indexes.

getValidImageVertices()

ordering specifies how the vertices should be arranged.

valid image vertices is basically the tightly fit convex hull of the image. Usually an image has NULL values and are internally not upright rectangular. This can cause problems some spatial filters.

The default implementation is to return the bounding rect.
