SoGLBufferObject.Map Method (SoBufferObject.AccessModes, UInt64, UInt64)

SoGLBufferObjectMap Method (SoBufferObjectAccessModes, UInt64, UInt64)

This function extends the map(AccessMode) method by allowing the mapping of a sub part of the buffer object into CPU memory.

Namespace: OIV.Inventor.Devices
Assembly: OIV.Inventor.GL (in OIV.Inventor.GL.dll) Version: 2024.2.2.0 (10.16.2.0)

Syntax

C++

Copy

public override SbNativeArray<byte> Map(
	SoBufferObjectAccessModes accessMode,
	ulong offset,
	ulong count
)

Public Overrides Function Map ( 
	accessMode As SoBufferObjectAccessModes,
	offset As ULong,
	count As ULong
) As SbNativeArray(Of Byte)

public:
virtual SbNativeArray<unsigned char>^ Map(
	SoBufferObjectAccessModes accessMode, 
	unsigned long long offset, 
	unsigned long long count
) override

abstract Map : 
        accessMode : SoBufferObjectAccessModes * 
        offset : uint64 * 
        count : uint64 -> SbNativeArray<byte> 
override Map : 
        accessMode : SoBufferObjectAccessModes * 
        offset : uint64 * 
        count : uint64 -> SbNativeArray<byte>

Parameters

accessMode: Type: OIV.Inventor.DevicesSoBufferObjectAccessModes
offset: Type: SystemUInt64
count: Type: SystemUInt64

Return Value

Type: SbNativeArrayByte

Reference to data in the mapped region of the OpenGL buffer.

Remarks

On some systems this method has better performance.

Notes:

It is not necessary to bind an OpenGL context before calling this method.
The OIV.Inventor.Devices.SoGLBufferObject.Unmap() method must be called before using the buffer for any OpenGL operation, otherwise the operation will produce an error.
