Constructor Details

VertexBufferObject

public VertexBufferObject()

Creates a Vertex Buffer Object (VBO).

Method Details

bind

public void bind(int target)

Binds this VBO with specified target. The target in the tutorial should be GL_ARRAY_BUFFER most of the time.

Parameters:

target - Target to bind

uploadData

public void uploadData(int target,
 FloatBuffer data,
 int usage)

Upload vertex data to this VBO with specified target, data and usage. The target in the tutorial should be GL_ARRAY_BUFFER and usage should be GL_STATIC_DRAW most of the time.

Parameters:

target - Target to upload

data - Buffer with the data to upload

usage - Usage of the data

uploadData

public void uploadData(int target,
 long size,
 int usage)

Upload null data to this VBO with specified target, size and usage. The target in the tutorial should be GL_ARRAY_BUFFER and usage should be GL_STATIC_DRAW most of the time.

Parameters:

target - Target to upload

size - Size in bytes of the VBO data store

usage - Usage of the data

uploadSubData

public void uploadSubData(int target,
 long offset,
 FloatBuffer data)

Upload sub data to this VBO with specified target, offset and data. The target in the tutorial should be GL_ARRAY_BUFFER most of the time.

Parameters:

target - Target to upload

offset - Offset where the data should go in bytes

data - Buffer with the data to upload

uploadData

public void uploadData(int target,
 IntBuffer data,
 int usage)

Upload element data to this EBO with specified target, data and usage. The target in the tutorial should be GL_ELEMENT_ARRAY_BUFFER and usage should be GL_STATIC_DRAW most of the time.

Parameters:

target - Target to upload

data - Buffer with the data to upload

usage - Usage of the data

destroy

public void destroy()

Deletes this VBO.

Specified by:

destroy in interface Lifecycle

getId

public int getId()

Getter for the Vertex Buffer Object ID.

Returns:

Handle of the VBO
