![]() ![]() I understand that decimation is done by creating ten or so different LoD versions of the model, which are deployed as necessary depending on how challenged the graphics card feels. Bentley bought PointTools, which is now their Point Cloud engine - but rotation is not nearly as satisfactory as implimented in Microstation - 'only partial implimentation' apparently - don't know why. ![]() I have an ancient copy of PointTools, which rotates large point clouds splendidly, with decimation (temporary drastic simplification) of the image while rotation is happening, and re-appearance of the full image when rotation stops. That's the essence, or one of the essentials, of Point Cloud enablement - algorithms to make display rotation etc go just as fast as with a relatively 'light' vector model, when meshes and point clouds are usually extremely 'heavy'.ĭon't know how pure-mesh based 3D modellers do it, but un-enabled CAD (like present Brics) simply stalls, however hot the graphics card. No clue if Meshes will slow down Bricscad 3D display ![]()
