Normally if one were to access color or pixel information this would be done using a data buffer/array...Now if I wanted to access the actual texture that is set up by glTexture2D and bound to an object...how would I go about doing this? Is there a command that would allow me to access the texture resident in video memory pixel by pixel and return color information? My reason for something like this is having both a resident texture as a GL object and a data buffer takes up too much memory...I think it would be more efficiant to access the GL texture object...
