Method Detail

maybeUpdate

public boolean maybeUpdate(com.jogamp.opengl.GL3 gl,
                           RenderInstances rinst)

Potentially update the internal VBOs

Parameters:

gl - context handle

rinst - instance storage

Returns:

true if updated, false if nothing changed

getBindVersion

public int getBindVersion()

Returns:

version incremented when attributes need to be re-bound

isValid

public boolean isValid()

Description copied from interface: GLResource

Returns true if resource can be used (i.e. hasn't been disposed)

Specified by:

isValid in interface GLResource

Overrides:

isValid in class GLResourceBase

Returns:

true if the resource can be used
