8.3.5.3.3 Rendering Method (Current)
Prev	8.3.5.3 Query Parameters For Rendered MPR Volume Resources and Rendered 3D Volume Resources	Next

The "renderingmethod" parameter specifies the display algorithm to be applied to the Volume Data.

The syntax of this parameter is:

%s"renderingmethod=" 1#( %s"volume_rendered" / %s"maximum_ip" / %s"minimum_ip" / %s"average_ip" )

Where

volume_rendered	A method where each XY pixel of the rendered view is determined by accumulating the set of non-transparent voxel samples along a ray.
maximum_ip	A method that projects the interpolated sample with maximum intensity that falls in the path of each ray traced from the viewpoint to the plane of projection.
minimum_ip	A method that projects the interpolated sample with minimum intensity that falls in the path of each ray traced from the viewpoint to the plane of projection.
average_ip	A method that projects the mean intensity of all interpolated samples that fall in the path of each ray traced from the viewpoint to the plane of projection.

Note

These values correspond to the differently capitalized values of Rendering Method (0070,120D). See Section C.11.23 in PS3.3 and Section C.11.30 in PS3.3.
There is no parameter to control the type of projection used during rendering. Rendered 3D Volume Resources use Orthographic projection. See Figure C.11.30-1 in PS3.3.
For Rendered MPR Volume Resources, this parameter describes the display algorithm to apply when the slab thickness is greater than one voxel. This parameter value is typically average_ip.

If "renderingmethod" is not present, the origin server may apply a default rendering method, based on the resource, or alternatively, return 400 (Bad Request) and may include an appropriate Status Report.

If the Target Resource is a Volumetric Presentation State, the origin server shall return a 400 (Bad Request) and may include an appropriate Status Report.
