MEvaluationGraph Class Reference

#include <MEvaluationGraph.h>

Class Description

Evaluation graph object.

The evaluation graph holds information about what in the scene is considered to be live (or time dependent). It is constructed out of dirty messages, and has full knowledge of dependencies between live nodes. This is why it can be used to replace regular Maya evaluation with dirty propagation.

The evaluation graph is linked to DG context and graph construction. This context is fully respected during evaluation.

Evaluation with the evaluation graph can be done in different modes and depending on settings, a different executor is used to traverse the graph and do complete or partial graph computation. Unlike the DG, the evaluation with evaluation graph is using forward evaluation model. Graph topology is defined by directional connections between evaluation nodes.
