This work was started as part of GSOC2010 within the soc-2010-nicolasbishop SVN branch, but more recently I have continued development as a patch against trunk. The new patch will have only Ptex changes, the other changes from soc-2010-nicolasbishop such as paint masks are not part of this project.<br /> <br /> == Ptex library ==<br /> The [http://ptex.us/index.html Ptex] library is currently used for loading and saving Ptex files; in the future it will probably be needed for integration in the internal renderer as well.<br /> <br /> Licensing note: the Ptex license is BSD-new, which is [http://en.wikipedia.org/wiki/BSD_licenses#3-clause_license_.28.22New_BSD_License.22_or_.22Modified_BSD_License.22.29 GPL-compatible].<br /> <br /> I have imported Ptex into the extern/ directory. Since the library is C++, I've also added a small C wrapper which attempts to mirror the Ptex API very closely. (I've only wrapped the parts of the library currently in use, but it should be very quick to extend if we need additional functionality.) The header and source files are extern/ptex/ptex.h and extern/ptex/ptex_C_api.c.<br /> <br /> == DNA ==<br /> Ptex data is stored primarily as CustomData, but has some limited integration into textures as well.<br /> <br /> === Brush ===<br /> The only change needed for brushes is to add a field for the current Ptex paint tool (same as for all the other paint modes.)<br /> <br /> === CustomData ===<br /> Added a new CustomData type, CD_MPTEX.<br /> <br /> === Mesh ===<br /> Added a field to store the active subface, similar to the active face.<br /> <br /> === MeshData ===<br /> typedef struct MPtexSubface {<br /> void *data;<br /> /* resolution in U and V directions, always a power of two */<br /> int res[2];<br /> int flag, pad;<br /> } MPtexSubface;<br /> <br /> typedef struct MPtex {<br /> struct MPtexSubface subfaces[4];<br /> /* equal to face's number of vertices */<br /> int totsubface;<br /> /* enum PtexDataType */<br /> char type;<br /> char channels;<br /> char pad[2];<br /> } MPtex;<br /> <br /> === Texture ===<br /> Added a new field to store the name of a Ptex layer, and added a new texture type, TEX_PTEX.<br /> <br /> = Patch =<br /> Again, work in progress!<br /> <br /> http://www.pasteall.org/19244/diff</div>
