QuickTime VR

advanced
#1

Greetings,

I’m working on a project that uses a collection of QuickTime VR movies of a space taken at different times of a year. I quickly realized that QuickTime was unable to handle more than 2 HD files – upon loading the 3rd, I received an “out of memory” error.

It’s clear that this QuickTime technology was made for computers with low memory for which they had to compensate by pre-rendering the file in advance. It looks like I’m going to have to find a way to do this in realtime with high-resolution photographs and I was wondering if anybody can recommend a good c++ library for doing perspective warping or any online resources.

Thanks,

Jeremy

IPP has fast image warping… might be worth investigation. pm me if you go that route as I have some old ofxCvImage type code but for IPP. it’s gathering dust… :wink:

also, anti grain geometry has different types of warping – it looks promising.

take care!

also take a look at this code theo posted some time ago:

don’t know if it’s what you need but it works in the gpu so i suppose it will be way faster than any library using the cpu.
