IMPLEMENTASI OBYEK GRAFIS 3-D DENGAN POV-Ray

Rudy Hartanto

Abstract


Abstract — The development of 3-D graphics applications leads to the generation of photo-realistic graphics image, which is implemented many applications, such us design, simulation, games as well as to making animated films. Rendering techniques used to generate the graphics image is still les realistic, because lack of real-world lighting models. Subsequent research led to the global illumination models that used a model of the light rays as in the actual physical environment. The algorithm that can implement global illumination models are ray-tracing algorithm. This algorithm is capable of producing 3-D graphic image of a high quality photo-realistic, but requires a complex mathematical equation and computation. POV-Ray is a tool used to implement the ray-tracing models to produce photo-realistic graphics image. These results show that the POV-Ray can generate 3-D graphic image of high qualityt.

Intisari— Perkembangan aplikasi grafis 3-D mengarah pada pembangkitan citra grafis foto-realistis, yang sangat diperlukan mulai dari aplikasi perancangan, simulasi, game sampai pembuatan film animasi. Teknik rendering yang digunakan untuk membangkitkan citra grafis masih belum realistis, karena belum didasarkan pada model pencahayaan dunia nyata. Penelitian selanjutnya mengarah pada model iluminasi global yang menggunakan model berkas cahaya seperti pada lingkungan fisik sebenarnya. Salah satu algoritma yang dapat mengimlementasikan model iluminasi global adalah algoritma ray-tracing. Algoritma ini mampu menghasilkan citra grafis 3-D kualitas tinggi mendekati foto-realistis, namun membutuhkan persamaan matematis dan komputasi yang kompleks. POV-Ray adalah salah satu tool yang digunakan untuk mengimplementasikan model ray-tracing untuk menghasilkan citra grafis foto-realistis. hasil penelitian ini menunjukkan bahwa POV-Ray dapat menghasilkan citra grafis 3-D kualitas tinggi.

Kata kunci— Foto-realistis, iluminasi global, ray-tracing, POVRay.
