Method Detail
-
getNumIndices
public int getNumIndices()
- Specified by:
getNumIndices
in interfaceIntIndexData
- Returns:
- the number of indices currently stored in this buffer
-
getNumMaxIndices
public int getNumMaxIndices()
- Specified by:
getNumMaxIndices
in interfaceIntIndexData
- Returns:
- the maximum number of indices this IntIndexArray can store.
-
setIndices
public void setIndices(int[] indices, int offset, int count)
Sets the indices of this IntIndexArray, discarding the old indices. The count must equal the number of indices to be copied to this IntIndexArray.
This can be called in between calls to
bind()
andunbind()
. The index data will be updated instantly.- Specified by:
setIndices
in interfaceIntIndexData
- Parameters:
indices
- the vertex dataoffset
- the offset to start copying the data fromcount
- the number of ints to copy
-
setIndices
public void setIndices(java.nio.IntBuffer indices)
Description copied from interface:IntIndexData
Copies the specified indices to the indices of this IntIndexBufferObject, discarding the old indices. Copying start at the currentBuffer.position()
of the specified buffer and copied theBuffer.remaining()
amount of indices. This can be called in between calls toIntIndexData.bind()
andIntIndexData.unbind()
. The index data will be updated instantly.- Specified by:
setIndices
in interfaceIntIndexData
- Parameters:
indices
- the index data to copy
-
updateIndices
public void updateIndices(int targetOffset, int[] indices, int offset, int count)
Description copied from interface:IntIndexData
Update (a portion of) the indices.- Specified by:
updateIndices
in interfaceIntIndexData
- Parameters:
targetOffset
- offset in indices bufferindices
- the index dataoffset
- the offset to start copying the data fromcount
- the number of ints to copy
-
getBuffer
public java.nio.IntBuffer getBuffer()
Returns the underlying IntBuffer. If you modify the buffer contents they wil be uploaded on the call to
bind()
. If you need immediate uploading usesetIndices(int[], int, int)
.- Specified by:
getBuffer
in interfaceIntIndexData
- Returns:
- the underlying int buffer.
-
bind
public void bind()
Binds this IntIndexArray for rendering with glDrawElements.- Specified by:
bind
in interfaceIntIndexData
-
unbind
public void unbind()
Unbinds this IntIndexArray.- Specified by:
unbind
in interfaceIntIndexData
-
invalidate
public void invalidate()
Invalidates the IntIndexArray so a new OpenGL buffer handle is created. Use this in case of a context loss.- Specified by:
invalidate
in interfaceIntIndexData
-
dispose
public void dispose()
Disposes this IntIndexArray and all its associated OpenGL resources.- Specified by:
dispose
in interfacecom.badlogic.gdx.utils.Disposable
- Specified by:
dispose
in interfaceIntIndexData
