“…For shadows, we simply implement a separable 31 × 31 joint bilateral filter [KCLU07] and it turns out already good enough. For glossy reflections, we refer to the filtering method in [LLK*19]. For global illumination, we use a 4‐level à‐trous wavelet filter, essentially 32 × 32.…”

Figure 1: We propose temporally reliable motion vectors for shadows (left, pink room scene), glossy reflections (middle, contemporary restaurant scene) and occlusions (right, PICA scene) that better explore and utilize temporal correspondences between adjacent frames. Our method significantly reduces noise, overblur and ghosting artifacts compared to the state of the art temporal reuse methods with traditional motion vectors. The quantitative evaluation metrics (RMSE and SSIM) are shown below the images.

“…Gambar 1. Proses rendering Ada dua jenis metode yang utama yang digunakan untuk rendering yaitu rasterisasi (juga dikenal sebagai scanline atau rendering poligon) [3] dan Ray Tracing [4]. Scanline rendering adalah algoritma untuk penentuan permukaan yang terlihat dari dalam grafik komputer 3D, yang bekerja secara baris per baris atau piksel per piksel.…”

Proses rendering pada pembuatan film 3D animasi merupakan pekerjaan yang sangat memakan banyak waktu dikarenakan banyaknya frame yang diperlukan untuk membuat film 3D animasi. Pada proses rendering satu frame dalam film 3D animasi biasanya membutuhkan waktu hingga beberapa jam dikarenakan proses kalkulasi render yang terdiri dari data model, data shader, data texture, dan data lighting dalam sebuah shot pada adegan 3D animasi. Dengan menggunakan proses render secara frame per frame maka proses render akan memerlukan waktu yang lama sehingga penulis akan melakukan penelitian pada proses rendering dengan menggunakan software game engine pada Unreal Engine 4 sebagai kalkulasi render secara realtime. Dari data yang semula dilakukan proses render pada software maya dan selanjutnya akan dilakukan perubahan data dari file maya diubah menjadi FBX file sebagai data yang akan di proses pada software Unreal Engine 4 (UE4). Dengan penggunaan game engine sebagai hasil akhir dalam menampilkan hasil render secara realtime sangatlah membantu dalam mendapatkan kelancaran pada sebuah proses produksi pada film 3D animasi. Kata Kunci—animasi 3D, rendering, real time render, game engine.The rendering process in making animated 3D movies is a very time-consuming job due to the large number of frames needed to make animated 3D films. In the rendering process one frame in an animated 3D movie usually takes up to several hours because the rendering calculation process consists of model data, shader data, texture data, and lighting data in a shot on a 3D animated scene. By using the rendering process in a frame per frame, the rendering process will require a long time so the writer will conduct research on the rendering process by using the game engine software on Unreal Engine 4 as a realtime rendering calculation. From the data that was originally done in the virtual software rendering process and then the data will be changed from the virtual file to be converted into FBX file as data that will be processed in the Unreal Engine 4 software (UE4). Using the game engine as the final result in displaying rendering results in realtime is very helpful in getting fluency in a production process in 3D animated films.Keywords—3D animation, rendering, real time rendering, game engine.

“…Reprojection‐based temporal data reuse has also been widely applied in denoising ray‐traced images. Many techniques rely on TAA‐like temporal filter to denoise path‐traced images rendered at very low sampling rates [SKW∗17, MMBJ17, SPD18, KIM∗ 19, LLCK19, WMB19, SA19, BBHW∗19]. One major problem of reusing samples in path‐tracing is the difficulty to obtain correct motion vectors for secondary shading effects like reflections and lighting.…”

Temporal Antialiasing (TAA), formally defined as temporally‐amortized supersampling, is the most widely used antialiasing technique in today's real‐time renderers and game engines. This survey provides a systematic overview of this technique. We first review the history of TAA, its development path and related work. We then identify the two main sub‐components of TAA, sample accumulation and history validation, and discuss algorithmic and implementation options. As temporal upsampling is becoming increasingly relevant to today's game engines, we propose an extension of our TAA formulation to cover a variety of temporal upsampling techniques. Despite the popularity of TAA, there are still significant unresolved technical challenges that affect image quality in many scenarios. We provide an in‐depth analysis of these challenges, and review existing techniques for improvements. Finally, we summarize popular algorithms and topics that are closely related to TAA. We believe the rapid advances in those areas may either benefit from or feedback into TAA research and development.
