The objective of this research is to develop software which capable to reconstruct 3D object from 2D images as references using Generalized Voxel Coloring - Layered Depth Image method (GVC-LDI). This method reconstruct 3D object using LDI link list as help to find voxels which correspond to the objects based on color. To find the voxels, we calculate the color standard deviation of the pixels which is projected from the object. If the standard deviation is smaller than the threshold, the voxel evaluated as a part of the object. The process repeated for each voxel until it gets all of the voxels which shape the object. The voxels can be drawn to screen to get the photorealistic 3D object that represent the 2D images. In this research, we also compare the result of GVC-LDI and Generalized Voxel Coloring ? Image Buffer (GVC-IB) which is one of the GVC variant also. Future development of the software is automatic 3D modeling application and real time 3D animation application. Abstract in Bahasa Indonesia : Pada penelitian ini dikembangkan sebuah perangkat lunak untuk merekonstruksi obyek tiga dimensi dari kumpulan gambar dua dimensi dengan menggunakan metode generalized voxel coloring? layered depth image (GVC-LDI). Metode GVC-LDI ini melakukan rekonstruksi dengan bantuan link list LDI guna mencari voxel-voxel yang merupakan bagian dari obyek tiga dimensi berdasarkan warna. Guna penentuan voxel tersebut dilakukan perhitungan dari pixel-pixel yang merupakan proyeksi dari sebuah voxel. Perhitungan dilakukan dengan menggunakan standar deviasi warna untuk menentukan apakah pixel-pixel yang bersesuaian mewakili lokasi obyek yang sama. Apabila standar deviasi warna lebih kecil dari threshold maka dapat dikatakan bahwa voxel tersebut termasuk bagian obyek. Proses ini dilakukan secara berulang untuk semua voxel hingga didapatkan voxel-voxel yang merupakan bagian dari obyek. Voxel tersebut kemudian digambar pada layar monitor sehingga diperoleh hasil berupa obyek tiga dimensi yang menyerupai obyek asli yang terdapat pada gambar dua dimensi. Pada penelitian ini juga dilakukan perbandingan antara metode GVC-LDI dengan metode Generalized Voxel Coloring?Image Buffer (GVC-IB) yang juga merupakan varian dari metode GVC. Pengembangan dari perangkat lunak ini adalah pembuatan aplikasi 3D modeling secara otomatis dan pembuatan aplikasi animasi 3D secara real time. Kata Kunci : rekonstruksi tiga dimensi, generalized voxel coloring, layered depth image.

In this paper, we implemented 3D object modeling from 2D input images. Modeling is performed by using volumetric reconstruction approaches by using volumetric reconstruction approaches, the 3D space is tesselated into discrete volumes called voxels. We use voxel coloring method to reconstruct 3D object from synthetic input images by using voxel coloring, we can get photorealistic result and also has advantage to solve occlusion problem that occur in many case of 3D reconstruction. Photorealistic 3D object reconstruction is a challenging problem in computer graphics and still an active area nowadays. Many applications that make use the result of reconstruction, include virtual reality, augmented reality, 3D games, and another 3D applications. Voxel coloring considered the reconstruction problem as a color reconstruction problem, instead of shape reconstruction problem. This method works by discretizing scene space into voxels, then traversed and colored those voxels in special order. The result is photorealitstic 3D object. Abstract in Bahasa Indonesia : Dalam penelitian ini dilakukan implementasi untuk pemodelan obyek tiga dimensi yang berasal dari gambar dua dimensi. Pemodelan ini dilakukan dengan menggunakan pendekatan volumetric. Dengan menggunakan pendekatan volumetric, ruang tiga dimensi dibagi menjadi bentuk diskrit yang disebut voxel. Kemudian pada voxel-voxel tersebut dilakukan metode pewarnaan voxel untuk mendapatkan hasil berupa obyek tiga dimensi yang bersifat photorealistic. Bagaimana memodelkan obyek tiga dimensi untuk menghasilkan hasil photorealistic merupakan masalah yang masih aktif di bidang komputer grafik. Banyak aplikasi lain yang dapat memanfaatkan hasil dari pemodelan tersebut seperti virtual reality, augmented reality dan lain-lain. Pewarnaan voxel merupakan pemodelan obyek tiga dimensi dengan melakukan rekonstruksi warna, bukan rekonstruksi bentuk. Metode ini bekerja dengan cara mendiskritkan obyek menjadi voxel dan kemudian melakukan pengecekan secara berurutan terhadap proyeksi voxel ke gambar input untuk menentukan apakah voxel tersebut merupakan bagian dari obyek atau bukan. Sehingga pada akhirnya akan dihasilkan suatu model tiga dimensi yang photorealistic. Kata kunci: pewarnaan voxel, pemodelan tiga dimensi, obyek photorealistic.

ACCELERATION RENDERING METHOD ON RAY TRACING WITH ANGLE COMPARISON AND DISTANCE COMPARISON liliana, Liliana; Adipranata, Rudy

In computer graphics applications, to produce realistic images, a method that is often used is ray tracing. Ray tracing does not only model local illumination but also global illumination. Local illumination count ambient, diffuse and specular effects only, but global illumination also count mirroring and transparency. Local illumination count effects from the lamp(s) but global illumination count effects from other object(s) too. Objects that are usually modeled are primitive objects and mesh objects. The advantage of mesh modeling is various, interesting and real-like shape. Mesh contains many primitive objects like triangle or square (rare). A problem in mesh object modeling is long rendering time. It is because every ray must be checked with a lot of triangle of the mesh. Added by ray from other objects checking, the number of ray that traced will increase. It causes the increasing of rendering time. To solve this problem, in this research, new methods are developed to make the rendering process of mesh object faster. The new methods are angle comparison and distance comparison. These methods are used to reduce the number of ray checking. The rays predicted will not intersect with the mesh, are not checked weather the ray intersects the mesh. With angle comparison, if using small angle to compare, the rendering process will be fast. This method has disadvantage, if the shape of each triangle is big, some triangles will be corrupted. If the angle to compare is bigger, mesh corruption can be avoided but the rendering time will be longer than without comparison. With distance comparison, the rendering time is less than without comparison, and no triangle will be corrupted.

Usually we use paper to draw sketch of room for designing building. Using paper can cause a problem especially for changing the sketch or size of the room. To solve that problem, we can use software to design sketch of the room. Nowadays there are many software can be used but many of those can only view in two dimension, top side. Using only two dimensions viewing, user have difficulties to imagine the real room in three dimensions. Also there are software which can view in three dimensions, but unfortunately the price of those software is so high. In this paper, we implement software to help user to design the sketch of the room in two dimensions, but the result can be viewed in three dimensions. In three dimensions view, user can do movement like view the real world. This software also can be used to create building have multi level, and the accessories that can be used are floor, wall, door, window and stair. To implement this software we use OpenGL library. Abstract in Bahasa Indonesia : Untuk merancang denah ruang pada sebuah bangunan, biasanya dilakukan penggambaran sketsa ruang yang diinginkan pada kertas. Tidak semua orang, terutama orang yang awam terhadap bidang arsitektur, membayangkan sebuah gambar denah sebagai ruangan akan sangat menyulitkan. Untuk menjembatani antara perancang dengan pelanggan, antara rancangan denah dalam bentuk 2D dengan visualisasi dalam bentuk 3D, maka dalam penelitian ini dikembangkan sebuah perangkat lunak yang mampu menghasilkan visualisasi bentuk sebuah ruang dari inputan berupa gambar denah 2D tampak atas. Dengan adanya fasilitas editor pada perangkat lunak ini, maka perancang dapat melakukan perubahan denah ataupun ukuran yang sudah tergambar dan langsung menampilkan hasil visualisasinya. Oleh karena itu, pada penelitian ini, dikembangkan pembuatan perangkat lunak editor denah ruang secara 2D yang dapat langsung divisualisasikan dalam bentuk 3D dengan ukuran yang sama dengan yang diinputkan pada gambar denahnya. Pada visualisasi yang berbentuk 3D, pengguna dapat melakukan penjelajahan ruang seperti berada pada ruang secara nyata. Pada perangkat lunak ini, bangunan dapat dibuat bertingkat dan bagian ruang yang disediakan adalah lantai, dinding, pintu, jendela serta tangga.
