Adaptive Rendering for Large Datasets

Post by LAL » Mon Jul 04, 2016 1:16 am

I've just upgraded from v8 to the latest release and I was wondering if any adaptive rendering had been implemented? Several years ago I experimented with replacing another graphing control we use to display DEMs with TeeChart. TeeChart was appreciably slower because it seemed to render every point of the grid, even if the it was sub-pixel in size. At the time I thought about trying to filter every n-th point from the dataset based on the size of the control, the size of the data, the zoom state etc., to remove any sub-pixel rendering but never got around to it.

Does the current version adaptively render large datasets, or would I still have to implement my own filtering?

Cheers
