I propose we > begin the discussion. Here are some topics: Ooops :> Sorry for the late reply guys. First of all, thanks to Moritz for this initiative and Rick LaMont for the interresting historical notes. Some general remarks about 3Delight's texture format: 1 - four formats are supported: plain textures, latlong, cubeface and shadow 2 - resolution can be of any size, not only powers of 2; 3 - mipmaps are diagonal; 4 - Tile Size may change in the future. 'tdlmake' uses 64x64 for textures and 32x32 for shadows but the renderer does accept any tile size. Depending on the results of some tests we are running, this may change to 32x32 all around. Here are the tags used by 3delight: Tags common to latlong, cubeface and plain textures : ----------------------------------------------------- TIFFTAG_IMAGEWIDTH : x res of subimage (minimum = 1) TIFFTAG_IMAGELENGTH : y res of subimage (minimum = 1) TIFFTAG_SAMPLESPERPIXEL : 1 to 6 channels TIFFTAG_BITSPERSAMPLE : 8, 16, 32 (tdlmake will also accept 1 and 4 as INPUT but output will be converted to 8) TIFFTAG_SAMPLEFORMAT : SAMPLEFORMAT_IEEEFP, SAMPLEFORMAT_INT, SAMPLEFORMAT_UINT TIFFTAG_COMPRESSION : COMPRESSION_ADOBE_DEFLATE, COMPRESSION_PACKBITS COMPRESSION_LZW, COMPRESSION_NONE, COMPRESSION_SGILOG TIFFTAG_PREDICTOR : 2 (not set when no compression or SAMPLEFORMAT_IEEEFP) TIFFTAG_ORIENTATION : ORIENTATION_TOPLEFT TIFFTAG_PHOTOMETRIC : PHOTOMETRIC_MINISBLACK, PHOTOMETRIC_RGB, PHOTOMETRIC_LOGLUV (when COMPRESSION_SGILOG) TIFFTAG_EXTRASAMPLES : EXTRASAMPLE_ASSOCALPHA, EXTRASAMPLE_UNASSALPHA (depends on source image) TIFFTAG_PLANARCONFIG : PLANARCONFIG_CONTIG TIFFTAG_TILEWIDTH : 64 TIFFTAG_TILELENGTH : 64 TIFFTAG_SOFTWARE : "tdlmake 3.0.0 (" __DATE__ ")" (version can vary of course) Specific to ``plain'' textures: ------------------------------- TIFFTAG_PIXAR_TEXTUREFORMAT : "Plain Texture" TIFFTAG_PIXAR_WRAPMODES : "%s,%s" (uwrap,vwrap). Three wrap modes are supported : 'periodic', 'black' and 'clamp'. Specified on the command-line to 'tdlmake'. Specific to CubeFace environment maps: -------------------------------------- TIFFTAG_PIXAR_TEXTUREFORMAT : "CubeFace Environment" TIFFTAG_PIXAR_IMAGEFULLWIDTH : 1/3 x res of subimage TIFFTAG_PIXAR_IMAGEFULLLENGTH : 1/2 y res of subimage TIFFTAG_PIXAR_FOVCOT : 1.0 / tan(fov/2.0) TIFFTAG_PIXAR_WRAPMODES : "clamp,clamp" At least one package (BMRT) ensures that if a cube face image is smaller than one tile it gets its own tile. This puts a limit on the image size (I guess "RenderDotC" is also like this but I might be wrong). 3Delight does not care about tile boundaries. I leave this topic to the discussion step. Specific to LatLong environment maps: ------------------------------------- TIFFTAG_PIXAR_TEXTUREFORMAT : "LatLong Environment" TIFFTAG_PIXAR_WRAPMODES : "periodic,periodic" Specific to Shadow maps: ------------------------ TIFFTAG_PIXAR_TEXTUREFORMAT : "Shadow" TIFFTAG_SAMPLEFORMAT : SAMPLEFORMAT_IEEEFP TIFFTAG_TILEWIDTH : 32 TIFFTAG_TILELENGTH : 32 TIFFTAG_PIXAR_MATRIX_WORLDTOSCREEN : world to NDC matrix TIFFTAG_PIXAR_MATRIX_WORLDTOCAMERA : world to camera matrix _______________________________________________ RMan-Develop mailing list RMan-Develop@lists.sektor37.de http://lists.sektor37.de/mailman/listinfo/rman-develop --------------030902090708010205040703-- --------------010107040105050402080903 Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ kimageshop mailing list kimageshop@kde.org https://mail.kde.org/mailman/listinfo/kimageshop --------------010107040105050402080903--
