haydn.trigg Posted March 31, 2013 Posted March 31, 2013 Could someone provide me with the information on creating a 3D Texture as used for the Volumemetric Clouds. 3D Red and Green DDS File that is 32x32x32.
ulf.schroeter Posted April 1, 2013 Posted April 1, 2013 Volumetric clouds use a 2D grayscale texture with 4 identical-sized subimages for initialization. See <sdk-root>/data/samples/objects/textures/cloud_d.png for an example (128x512pixel). The internally use 3D density texture with 4 layers will be build from this 2D image. Each subimage should tile seamlessly.
manguste Posted April 1, 2013 Posted April 1, 2013 Yep, just one note: to convert such 2D into 3D, you can use ImageDDS (check the last usage example).
haydn.trigg Posted April 4, 2013 Author Posted April 4, 2013 Is there a program where I can put in a model and it will create a 3D Texture appropriately for me.Say I create a sphere, apply some noise and create a cloud. How would I then use that in a volume?
manguste Posted April 4, 2013 Posted April 4, 2013 Hm, it could be some 3D noise generator that outputs a 3D texture or 2D texture slices. Can't name any, sorry, did not use them.
