Hey Lars, Thanks for that - it's saved me days of effort. I got wrapped up in another issue that's needing sorted first. I was struggling to get sensible data from some TIFFs, but I think it's because they're way over the 4Gb limit and have been saved as BigTIFFs, so I need a Delphi unit/library that handles BigTIFF. Some months are just like the labours of Sisyphus .... Eric

Hi, Are there any plans, or has anyone added support for TIFF > 4GB? Cheers

Hi, So, at the moment, I have GeoTIFF files and I'm using TGLHeightField to display the grid and create a DEM. The GeoTIFF files are huge and the performance of TGLHeightfield has fallen offa cliff, so I'm looking at TGLTerrainRenderer instead. TGLHeightTileFileHDS seems to be perfect for what I need to do, so I'm trying to create the HTF file from the TIFF using TGLHeightTileFile. When trying to add the height value, my data consists of Single values, but TGLHeightTileFile.CompressTile(x, y, ts,...

Hi, Yes, that's how I've been telling people to resolve this, but was just hoping there might be a programming option I can use so they don't need to.

I have both an integrated Intel GPU and a dedicated Nvidia and occasionally run into problems when the Intel card is the primary one - users report grey blocks overlaying part of the application and an inability to click certain areas. These go away when you switch to the Nvidia card, so I was wondering if this selection can be done programatically in the application, perhaps when you create the Rendering Context on initialization? TLDR: Can you select the graphics card to use from within the ap...

I'd like to display some TIFF files, so I looked at the MultiTexture demo, which works for really small files, but I quickly run into an Out Of Memory error. Is there any way to load and display images that could exceed 28442x32184 pixels in size?

Hi Pavel, Thanks for that - I'm downloading that example now. Cheers Eric

Hi, Is there a way/setting that will remove the curtains/sides from the Heightfield? I want to just see the top layer, like a cloth covering the points, rather then like the attached. Many thanks Eric
