Hi, Currently we're using 3DS models (entire city's) with TGA imagery for textures. At the initial run of the database in the viewer we build ive's of all the models and associated LOD's - I'm guessing (in absence of our developers who are on holiday) that we're using OSGConv to convert the models to the ive format - my question is this: When ive's are built for models does the input texture type determine the compression of the final ive? The reason I ask is that for convenience we'd like to move away from TGA imagery to TIFF or JPEG , but will this alter the final size of the ive's and ultimately the performance of the rendering? I'd appreciate any input here as in the absence of the programmers I need to give an answer about this to our data suppliers ASAP. Not to over simplify it but we've gone from dealing with 5,000 models to 150,000 models in the last 12 months in our databases and need to optimise the models as much as possible - I know that 3DS is not a particularly good format for alot of optimising techniques but we use it from a 'ability to resupply' to end users point of view. That said we also handle nearly all common formats so if anyone has an idea on a better format which I can justify the use of to the company that would be great.
... Thank you!
