Hello,

I am trying to do something with Ogre using 3D textures. I would like to update a 3D-texture by going through it slice-by-slice and recalculating the color values. However, in each step I also need to access the previous slice somehow to read the values. Setting up a slice as a render target is easy, but is it possible to feed such a slice as a 2D-texture input to a shader, or do I need to explicitly copy it into a separate 2D texture?

Thanks.

Hi, so the question ist pretty much the title. I have a 3d volume loaded as raw data [256, 256, 256] = size(A). It contains only values of zero's and ones, where the 1's represent the structure and 0's the "air". I want to visualize the structure in matlab and then run an algorithm on it and put… >>> More

Force Direct3D anti-aliasing in a Direct3D game?

Some old games look really jagged nowadays on large displays without any anti-aliasing, but don't have any option built-in to the game to enable it. On a PC with an NVIDIA graphics card, it's possible to force anti-aliasing in the NVIDIA control panel which can really improve this. But I'm playing… >>> More
