“…Untuk menghasilkan pencahayaan yang baik, dibutuhkan beberapa sumber cahaya tambahan selain sumber cahaya yang sudah terpasang [2], [5], [6]. Penambahan sumber cahaya tambahan ini tergantung pada tuntutan skenario dan sangat dipengaruhi oleh keinginan sutradaranya.…”

Lighting is one of the most important things in the world of cinematography. There are several parameters that must be considered to produce good lighting. There are so many permutations in the lighting arrangement. It causes complexity of the process and there is no simple way to do the calculation. This complexity is compounded by the fact that each director has their own style in lighting arrangements in the film production process.This paper refers to the tabulation of the results of interviews with three movie directors and then the similarities of the three were taken. In this study, a fuzzy logic structure was built with five parameters of lighting arrangement, namely: the situation of the set, the camera's point of view, the installed light intensity, theposition and direction of the camera, and the emotions of the character. This research was conducted using 20 animated movie scenes that were built using Unity. The assessment of the output is done manually by several animated film designers. As a res ult, the designers assess that 80% of the lighting arrangement has been as expected.

“…To gain a better initial lighting set, the script uses the lighting scrapbook. Lighting scrapbook is a webbased application that gives a lighting set based on a database [6]. The database itself is based on many experiments that involved the director's behaviour.…”

“…In order to gain a good lighting, it often requires the additional light source other than the light source that has been installed [1,[6][7]. The addition of this additional light source is depending on the demand of the scenario also highly dependent to the director's behavior.…”

Lighting is one of the very important things in cinematography. Lighting in cinematography is used not only to illuminate the objects, but it has many important roles such as to make the object looks sharper, has tone, depth and separation, and so on. There are some parameters that affect the lighting result, such as light source type that is used, its colour, intensity, position, and direction. Unfortunately, lighting has so many permutations and variations and there is more than one right way to light the scene. In this research, a designer designs some scenes that will be used as inputs. In this study, the authors found that lighting set is strongly influenced by five important things, which are: the situation of the scene, Point-of-View, the intensity of the attached light sources, camera position, and emotion of the characters, that we called as the SPICE system that is the abbreviation from situation, PoV, intensity, camera, and emotion. some additional light sources will be added into the scene automatically according to the scenario and director's behaviour using the SPICE system that we propose. The SPICE framework has two fuzzy inference systems in calculating the intensity of light that hits an object and some additional light sources that are added to the scene automatically to make it looks much better. This research will make a calculation to gain the best scenes as an output. There are 20 scenes used in this research. As the final result, designers assess 80% outputs have been as expected.

“…A series of recent techniques that combine ideas from different approaches with precomputations allow real-time GI with dynamic lighting in static scenes. Jendersie et al [2016] use surfels that are shaded in real-time and a clustered hierarchy with precomputed light links to propagate the indirect illumination to (ir)radiance caches. The technique of Silvennoinen et al [2017] use radiance probes with precomputed transport terms to iteratively propagate the indirect illumination over multiple bounces to a lightmap.…”

Figure 1: A Many-Light Global Illumination approach is used to bake a compact light transport representation to a lightmap, while real-time frame rates are maintained. At any time, scene interactions (e.g., moving objects, adjusting lights) are allowed, and the illumination is seamlessly transformed from the old state to the new. A prioritizing update scheme resolves illumination errors in a way that the most significant changes are treated within the first seconds without noise or flickering artifacts.
