Method Detail

setErrorReporter

void setErrorReporter(org.j3d.util.ErrorReporter reporter)

Register an error reporter with the engine so that any errors generated by the node's internals can be reported in a nice, pretty fashion. Setting a value of null will clear the currently set reporter. If one is already set, the new value replaces the old.

Parameters:

reporter - The instance to use or null

isVisible

boolean isVisible()

Check to see if the surface is visible. If it is not visible, we don't want to do any rendering.

Returns:

True when the surface is really visible

requiresNewContext

boolean requiresNewContext()

Check to see if we should generate a new context now.

Returns:

true when the conditions require grabbing a new context
