EffectInstance.IsValid Method

EffectInstanceIsValid Method

Tests whether the effect instance is valid for rendering.

Namespace: Autodesk.Revit.DB.DirectContext3D
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.3.0.0 (25.3.0.0)
Syntax
public bool IsValid()
Public Function IsValid As Boolean
public:
bool IsValid()
member IsValid : unit -> bool

Return Value

Boolean
True if the effect instance is valid for rendering, false otherwise.
Remarks
The effect instances are internally associated with low-level graphics state and may become invalidated when the state changes. Therefore, an application should test each effect instance for validity before using it when submitting geometry. If the effect instance becomes invalid, the application should re-create it.
