Summary: radeon driver should support 3d texture maps without
raster fallback
Product: Mesa
Version: CVS
Platform: PC
OS/Version: Linux
Status: NEW
Severity: enhancement
Priority: P2
Component: Drivers/DRI/Radeon
AssignedTo: [email protected]
ReportedBy: [EMAIL PROTECTED]
the radeon driver currently does not support 3d texture maps, causing a raster
fallback. However, the hardware can do it, although with some limitations (not
more than one volume texture + one other texture simultaneously, no mipmaps).
I'll attach a patch which tries to address this, though I can't test it right
now (other than it compiles). Mipmaps are simply ignored (same as is already
done with cube maps, dunno, should there be a incredibly slow raster fallback
instead, or behaviour depend on if auto-mipmapping was used, or even a driconf
option?).
