added texture to diffuse material channel, for easier debugging of .dae file in blender
added filter for time interval
temporary scale the geometry for debugging purposes
Merge remote-tracking branch 'origin/master' into vrvis-branch-0-1-0
added volumes: GetScene now returns a single ".nii.gz" for layers that contain volume data
added "format/obj" to GetScene call, responds with multipart obj/mtl/Textures now
needs my latest commits in lib and packages.sh for all the additional stuff
Added bbox subsetting for volumes, added value clipping for volumes for the set radiometric interval in the layer. When various volumes as request result multipart response is created
Added tiem filter for volume response creation
Solved some conversion errors from projection to pixel space
Added creation of volumes based on 2D coverages and time as axis
Small change to allow creation of volumes from 2d coverages datasets which are not browse layers
Worked on correct creation of volume using vrt
Cleanup in GeoTIFF code and changed coordinate radius to 1 again
Changed the seed method, now it should not create high amount of data in the cache, as it only asks for specific times and specific tiles which are crossed by curtain coverage
Added check to set content type of returned multipart element and not just return application/ovtet-stream for all
Changed the affine attribute of volumes
Affine had only 3 dimensions needs 4
Tests for affine in relation to pixel resolution
Playing around with affine
Affine is now dependend on pixel resolution of tif
