Strata 3D（ストラタ 3D）は、Corastarによって開発されている3DCGソフトウェアである。短縮して、Strataともよばれる。日本語版もある。世界で最も普及している3D CGソフトの一つでもある。

現在の最新版はStrata CX 6であるが、CXシリーズ以前のStartaは、Strata proと呼ばれていた。

概要

Strata 3Dはかつて人気を集めていたMac OS向けの3DCGソフト、StrataVision 3Dおよび高機能版のStrataStudio Proの後継である。高能力で、初心者でも簡単に使用でき、比較的安価といったことがStrataの大きな特徴である。一時は、主要ソフトウェアの中に分類されるほどの売り上げを誇った。現在でも、アドビシステムズ製品との適合性が非常によいことから支持を得ている。ユーザインタフェースも、アドビ製品と非常によく似ている。

また、Strata CX 5などとは別売の、Strata FOTO 3Dと呼ばれる製品は、写真から立体的なオブジェクトを作成するという新機能をもうけている。

Strata 3D CX 5.1では、スクリプト言語のLua言語のスクリプティングが搭載されている。そのため、Strataで作成したオブジェクトやアニメーションを使用した3Dゲームやアニメーションの開発も、容易にこなせるようになった。またStrataでは、Luaスクリプトを自作しなくても3Dゲームやアニメーションの開発が行えるよう、サードパーティーによって作成されたスクリプトを用意している。

問題点

現在の最新版は解消されているが、4.2以前のStrata pro 3Dでは、「リソースパレット」と呼ばれる主要なパレットの表示に問題が起きることがあった。

In geology and related fields, a stratum (plural: strata) is a layer of sedimentary rock or soil with internally consistent characteristics that distinguish it from other layers. The "stratum" is the fundamental unit in a stratigraphic column and forms the basis of the study of stratigraphy.

Characteristics

The Permian through Jurassic strata in the Colorado Plateau area of southeastern Utah demonstrates the principles of stratigraphy. These strata make up much of the famous prominent rock formations in widely spaced protected areas such as Capitol Reef National Park and Canyonlands National Park. From top to bottom: Rounded tan domes of the Navajo Sandstone, layered red Kayenta Formation, cliff-forming, vertically jointed, red Wingate Sandstone, slope-forming, purplish Chinle Formation, layered, lighter-red Moenkopi Formation, and white, layered Cutler Formation sandstone. Picture from Glen Canyon National Recreation Area, Utah.

Each layer is generally one of a number of parallel layers that lie one upon another, laid down by natural processes. They may extend over hundreds of thousands of square kilometers of the Earth's surface. Strata are typically seen as bands of different colored or differently structured material exposed in cliffs, road cuts, quarries, and river banks. Individual bands may vary in thickness from a few millimeters to a kilometer or more. Each band represents a specific mode of deposition: river silt, beach sand, coal swamp, sand dune, lava bed, etc.

Naming

Geologists study rock strata and categorize them by the material of beds. Each distinct layer is typically assigned to the name of sheet, usually based on a town, river, mountain, or region where the formation is exposed and available for study. For example, the Burgess Shale is a thick exposure of dark, occasionally fossiliferous, shale exposed high in the Canadian Rockies near Burgess Pass. Slight distinctions in material in a formation may be described as "members" (or sometimes "beds"). Formations are collected into "groups" while groups may be collected into "supergroups".

Most population-based studies studied the association between inflammation and prostate cancer (PCa) by assessing C-reactive protein (CRP). As these findings have shown inconsistent results, we aimed to also study different markers that have been commonly taken as indications of inflammation. A coho
