Thanks for the responses, in answer to your questions: 1. The 20MB is a rough figure I got purely by checking free memory and paging file usage etc. before and after importing each model. I loaded up about 40 models and then averaged the figure to get 20MB.
To give you a better idea: I loaded up 30 models with textures and lost 554MB memory resources then loaded 100 models without textures and only used 480MB. All models were compiled after loading. Also on interpolating the models I'm achieving about 20-25 frames/sec depending on how many are loaded which drops to about 1 frame every 1 or 2 secs with textures. 2. None of the textures are mipmapped all have fixed level of detail. 3.I hadn't really thought about the compression of the images but I've fully decompressed most of them now to check the size and they just about doubled. But that's still only about 400K per model - not enought to justify the extra memory surely? Just in case my machine spec is of any use: 1.33Ghz Athlon 266FSB 256MB DDR RAM GeForce2Pro 64MB DDR Thanks for the input, Ewan ----- Original Message ----- From: Rob Crompton <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, December 12, 2001 5:54 PM Subject: Re: [JAVA3D] Memory consumption by textures > are JPEG textures decompressed on loading? 200K of jpeg could be a whole > lot more when decompressed. > > David Yazel wrote: > > >Are you mipmapping the textures?
