update in class BucketRenderer

compile

Compile all buckets into one BufferObject. Sets renderer to be ready when successful. When no data is available (buckets.countVboSize() == 0) then BufferObject will be released and buckets will not be rendered.

Overrides:

compile in class BucketRenderer

render

public void render(GLViewport v)

Description copied from class: BucketRenderer

Render all 'buckets'
