Description

nstats_raw prints a brief description of the node data in a uniform field. The information includes the field's dimensions, number of nodes, and for each component, the vector length, data type, number of non-zero nodes and sum of the node data values.

Inputs

&in

Reference to a uniform field with Node_Data of any type.

Outputs

info

The string containing the description of the field data.

Utility Macros

The low-level module nstats_raw is used in the Functional Macro nstats and the User Macro node_statistics. The latter also uses the UI Macro nstats_UI.

Example

An example application Node_Stats_Eg is provided that uses the AVS/Express sample image mandrill.x to display the node data statistics.

Files

iac_proj/nstats/ns_mods.v contains the nstats_raw module V definitions.

iac_proj/cp_utils contains source code for functions called by nstats_raw.

Prerequisites

This project relies on the successful installation of the following components. Without them it will not function correctly.

cp_utils project

Other Notes

By default the low-level library NStatsMods, which needs to be compiled, has the process set to express.

This module uses functions in the cp_utils library (available from IAC). It must be installed before compiling this project.
