Utg\u00e5van av JavaScript-biblioteket \u00e4r tillg\u00e4nglig Zdog 1.0<\/a><\/noindex>, som implementerar en 3D-motor som simulerar tredimensionella objekt baserat p\u00e5 vektoriska primitiva former Canvas och SVG, dvs. som realiserar ett tredimensionellt geometriskt rum med faktisk rendering av plana former. Projektets kod \u00e4r \u00f6ppen<\/a><\/noindex> \u00e4r licensierad under MIT. Biblioteket best\u00e5r av totalt 2100 rader kod och tar upp 28 kB utan minifiering, men g\u00f6r det m\u00f6jligt att skapa ganska effektfulla objekt, n\u00e4ra resultaten fr\u00e5n illustrat\u00f6rer.<\/p>\n

3D-objektmodeller i Zdog skapas med ett enkelt deklarativt API och s\u00e4tts ihop genom bindning och gruppering av enkla former<\/a><\/noindex>, s\u00e5som rektanglar, cirklar, trianglar, linjer, b\u00e5gar, polygoner och kurvor. I Zdog anv\u00e4nds rundade former, utan framtr\u00e4dande polygonala oj\u00e4mnheter. Enkla former visualiseras i mer komplexa tredimensionella representationer, s\u00e5som sf\u00e4rer, cylindrar och kuber. Ur utvecklarens perspektiv definieras sf\u00e4rer som punkter, torus som cirklar, och kapslar som tjocka linjer. <\/p>\n

De sammansatta elementen av objekten hanteras med h\u00e4nsyn till deras relativa positioner och sammanfogning med osynliga ankare. Alla dynamiska egenskaper, s\u00e5som transformationer, rotationer och skalning, representeras som vektoroperationer angivna med hj\u00e4lp av objektet Vector. Polygonala n\u00e4t st\u00f6ds f\u00f6r rumsliga objekt.<\/p>\n
