体积粒子渲染插件Thinkbox Krakatoa C4D v2.10.5 x64

Krakatoa™ for CINEMA 4D 是一个体积粒子渲染插件。Krakatoa C4D 完全集成在 CINEMA 4D 用户界面中。它实现了各种专用场景对象，例如用于从外部文件序列加载粒子的 PRT 加载器、用于将几何体积和表面转换为点云的 PRT 体积和 PRT 表面。原生 CINEMA 4D Emitter 和 TP 粒子，以及第 3 方 X-Particles 和 Turbulence FD 系统都通过专用中间对象原生支持。

渲染器
Krakatoa 渲染器是基于 CPU、高度优化和大量多线程的。
Krakatoa 的内存占用动态适应请求的功能，每个粒子的最小内存使用量为 26 字节。
Krakatoa 支持体积和附加粒子着色，并允许混合两种模式。
Krakatoa 具有粒子（又名点）渲染和体素渲染模式。
支持来自遮罩（保留）几何对象的自阴影和阴影投射。
Krakatoa 具有集成的运动模糊和景深相机效果。
渲染时粒子重新填充允许创建比提供的原始源更多的粒子。
交互式照明可以作为专用照明通道烘焙到 PRT 文件中，并允许快速重新渲染预照明粒子资产，以及基本的重新照明技术。

粒子源
Krakatoa C4D 支持原生 CINEMA 4D 发射器粒子和思考粒子；通过 PRT Loader 对象从磁盘加载的外部粒子源；通过 PRT Volume 和 PRT Surface 对象从几何体积和表面程序生成的粒子；通过 PRT Fractal 对象进行基于分形的分布。
目前支持的外部粒子文件格式有 Thinkbox 的 PRT 文件序列、RealFlow BIN 文件序列和 ASCII Comma-Separated Values CSV 序列。
Krakatoa C4D 包括将粒子数据保存到 PRT 文件的功能。它附带一个用于 PRT 保存/分区的集成选项，用于生成同一粒子系统的多个楔形。

PRT 对象
PRT Loader 对象可用于加载一个或多个外部文件序列。PRT 加载器允许使用偏移和动画曲线控件重新定时粒子。
PRT 体积对象可用于用粒子填充多边形网格的体积，并提供将粒子分布在几何表面范围内的选项。
PRT Surface 对象可用于在多边形网格的表面上快速分布随机粒子。
PRT Fractal 对象可用于基于随机种子、迭代控制和几个动画参数创建程序分形粒子分布。

粒子通道运算符标签
使用专用的 CINEMA 4D 标签，Krakatoa 公开了几个通道数据操作，可用于渲染器可用的任何有效粒子源。
这些操作包括将浮点或矢量通道设置为新值、通过标量因子缩放现有通道、将一个通道复制到另一个通道、将自定义通道分配为纹理使用的 UV 坐标用于高级映射效果的标签，以及使用 Krakatoa 的渲染时粒子乘法算法的粒子系统的重新填充。

Krakatoa™ for CINEMA 4D is a volumetric particle rendering plugin. Krakatoa C4D is fully integrated in the CINEMA 4D User Interface. It implements various dedicated scene objects like a PRT Loader for loading particles from external file sequences, PRT Volume and PRT Surface for converting geometry volumes and surfaces to point clouds. Both native CINEMA 4D Emitter and TP particles, as well as 3rd party X-Particles and Turbulence FD systems are supported natively via dedicated intermediate objects.

Renderer
The Krakatoa renderer is CPU-based, highly optimized and heavily multi-threaded.
Krakatoa’s memory footprint adapts dynamically to the requested features, with a minimum memory usage of 26 bytes per particle.
Krakatoa supports volumetric and additive particle shading and allows the mixing of the two modes.
Krakatoa features both Particle (aka Point) rendering and Voxel rendering modes.
Self-shadowing and shadow casting from matte (holdout) geometry objects are supported.
Krakatoa features integrated Motion Blur and Depth Of Field camera effects.
Render-time particle Repopulation allows the creation of more particles than the original source provided.
The interactive lighting can be baked to PRT files as a dedicated Lighting channel and allows for fast re-rendering of pre-lit particle assets, as well as for basic relighting techniques.

Particle Sources
Krakatoa C4D supports both native CINEMA 4D Emitter Particles and Thinking Particles; external particle sources loaded from disk via the PRT Loader object; procedurally generated particles from geometry volumes and surfaces via the PRT Volume and PRT Surface objects; and fractal-based distributions via the PRT Fractal object.
Currently supported external particle file formats are Thinkbox’ PRT file sequences, RealFlow BIN file sequences, and ASCII Comma-Separated Values CSV sequences.
Krakatoa C4D includes the ability to save particle data to PRT files. It ships with an integrated option for PRT Saving/Partitioning for generating multiple wedges of the same particle system.

PRT Objects
PRT Loader objects can be used to load one or more external file sequences. The PRT Loader allows for particle retiming using offset and animation curve controls.
PRT Volume objects can be used to fill the volume of a polygon mesh with particles and provides the option to distribute particles within a range from the geometry surface.
PRT Surface objects can be used to quickly distribute random particles on the surface of a polygon mesh.
PRT Fractal objects can be used to create procedural fractal particle distributions based on a random seed, iterations control and several animatable parameters.

Particle Channel Operator Tags
Using dedicated CINEMA 4D tags, Krakatoa exposes several channel data operations that can be used on any valid particle source usable by the renderer.
These operations include the setting of a Float or Vector Channel to a new value, the Scaling of an existing Channel by a Scalar factor, the Copying of one Channel into another, the assigning of a custom channel as UV coordinates to be used by a Texture tag for advanced mapping effects, and the Repopulation of a particle system using Krakatoa’s render-time particle multiplication algorithm.
