General Question #11

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I am new to this field of Image Processing and GPU so please bare with me.

Where will you use hardware accelerated DXT compressor? Is it to store
compressed texturs in the buffer? What if I want to read the bitmaps from
the GPU (glReadPixels()) and process it may be by sending them to the
different machine. Could I use this compressor to compress these bitmaps.
Also I won’t need to move them from GPU to CPU to compress using software
so it will be faster.

Also do you more information on nvimagediff tool?

Thanks.

The hardware accelerated DXT compressor is designed to be integrated into game 
asset
production pipelines. The GPU acceleration allows you to process your textures 
much
faster. The goal was to reduce the content creation turn-around time, so that 
artists
can preview the results faster. However, you are free to use it for any other 
purpose.

nvimagediff is a simple image diff utility, it only outputs the RMS and PSNR 
between
two images.
