VertexFormatIsValid Method

Tests whether the vertex format specification is valid for rendering.

Namespace: Autodesk.Revit.DB.DirectContext3D
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)

Syntax

public bool IsValid()

Public Function IsValid As Boolean

public:
bool IsValid()

member IsValid : unit -> bool

Return Value

Boolean
True if the vertex format specification is valid for rendering, false otherwise.

Remarks

The vertex format specifications are internally associated with low-level graphics state and may become invalidated when the state changes. Therefore, an application should test each vertex format object for validity before using it when submitting geometry. If the vertex format object becomes invalid, the application should re-create it.
