摘要

“合成摄影师”是一个全屏、实时、3D图形模拟,批判性地挑战了在计算机生成的虚拟环境中修复、过程性、线性和创意代理的概念。该应用程序正在渲染一个虚拟场景,描绘了一个火山山脉景观,位于中心的火山锥正在猛烈喷发,火山碎屑流和不同大小的岩石被喷出,熔岩河沿着斜坡向下流动,在锥脚下形成熔岩湖。地球和岩石撞击火山口底部并从斜坡上掉下来的低沉声音增强了这种现象的视觉效果。观看大约需要3- 5分钟,分为三个部分,中间部分构成核心体验,其中对场景中单个元素的控制交给算法。天气条件,火山喷发和虚拟相机的设置——它的动态运动和图像属性——是实时生成的。相机所使用的可能值的范围可以超越物理相机的能力,这使它成为一种超中介的代表性装置,产生部分抽象、半逼真的、不断变化的流体视觉,源自更广泛的美学光谱。这些算法还控制着各种后处理效果,这些效果被程序化地应用到相机馈送中。所有这些过程都是实时发生的,因此每一秒的体验都是通过独特的设置和参数的纠缠来构思的,这些设置和参数指导喷发及其表现。观看者所感知到的模拟的每一秒都是一次性事件,这构成了这种永恒的视觉奇观。艺术品可以在使用电视/投影仪的物理设置中显示,也可以在虚拟设置中作为应用程序产生的连续图像馈送(流)显示。

The synthetic cameraman
"The Synthetic Cameraman" is a full-screen, real-time, 3D graphics simulation that critically challenges the notions of remediation, processuality, linearity, and creative agency in computer-generated virtual environments. The application is rendering a virtual scene depicting a volcanic mountain landscape with a centrally located volcanic cone that is violently erupting with pyroclastic flow and rocks of different sizes being expelled as molten lava rivers are traveling down the slope forming a lava lake at the foot of the cone. The visual aspect of the phenomenon is enhanced by deep sounds of rumbling earth and rocks hitting the bottom of the caldera and falling down the slope. The viewing takes about 3--5 minutes and is divided into three sections with the middle section constituting the core experience where the control over individual elements in the scene is given over to the algorithms. The weather conditions, eruption, and the settings of virtual camera - its dynamic movement and image properties - are procedurally generated in real-time. The range of possible values that the camera is using can go beyond the capabilities of physical cameras, which makes it a hypermediated representational apparatus, producing partially abstract, semi-photorealistic ever changing fluid visuals originating from a broadened aesthetic spectrum. The algorithms are also controlling various post-processing effects that are procedurally applied to the camera feed. All of these processes are taking place in real-time, therefore every second of the experience is conceived through a unique entanglement of settings and parameters directing both the eruption and its representation. Each second of the simulation as perceived by the viewer is a one-time event, that constitutes this ever-lasting visual spectacle. The artwork can be displayed in a physical setting using a TV / projector or in a virtual setup as a continuous image feed (stream) produced by the application.
