Syntax

'Declaration
Public Sub DrawPrimitives ( _
    primitiveType As PrimitiveType, _
    startVertex As Integer, _
    primitiveCount As Integer _
)
'Usage
Dim instance As Device
Dim primitiveType As PrimitiveType
Dim startVertex As Integer
Dim primitiveCount As Integer

instance.DrawPrimitives(primitiveType, startVertex, primitiveCount)

public void DrawPrimitives (
    PrimitiveType primitiveType,
    int startVertex,
    int primitiveCount
)

public:
void DrawPrimitives (
    PrimitiveType primitiveType, 
    int startVertex, 
    int primitiveCount
)

public void DrawPrimitives (
    PrimitiveType primitiveType, 
    int startVertex, 
    int primitiveCount
)

public function DrawPrimitives (
    primitiveType : PrimitiveType, 
    startVertex : int, 
    primitiveCount : int
)

Not applicable.

Parameters

primitiveType
A member of the PrimitiveType enumerated type that describes the type of primitive to render.

startVertex
An index of the first vertex to load. Beginning at startVertex, the correct number of vertices is read out of the vertex buffer.

primitiveCount
A number of primitives to render. To determine the maximum number of primitives allowed, check MaxPrimitiveCount. The primitiveCount is the number of primitives as determined by the primitive type. If it is a line list, each primitive has two vertices. If it is a triangle list, each primitive has three vertices.

Exceptions

Exception type	Condition
InvalidCallException	The method call is invalid. For example, a method's parameter might contain an invalid value.

Remarks

This method should not be called with a single triangle at a time.
