Hi, I wanted to add a feature to our software that would allow a user to look at and explore (as in zoom in/out/pan etc) texture resources that are being used.
I’m currently using the texture system for all the OIIO operations, but if I want to basically display scaled down versions of the textures used, or zoomed in sections of the images, I’m not sure is using the texture call on the texture system across every pixel in the GUI window area is the most efficient way of going about it. Conversely, going down to the file level and doing scan-line or tile based reads on a suitable mipmap image on the raw pixel level has its own complexity too. What is the best way to efficiently get and display full/partial textures? I hav a feeling the raw pixel data route would be the best (with post scaling/framing as needed in the GUI system). Thanks in advance for any pointers on this one … Cheers, Simon _______________________________________________ Oiio-dev mailing list [email protected] http://lists.openimageio.org/listinfo.cgi/oiio-dev-openimageio.org
