工业自动化系统与集成 产品数据表示与交换 第46部分：集成通用资源：可视化呈现

[中文适用范围]： 在 STEP 模块和资源库 (SMRL) v11 中发布，未单独发布 ISO 10303-46 指定用于视觉呈现的集成资源构造。 ISO 10303-46 规定了可显示产品信息可视化的集成资源。 ISO 10303-46 中描述的表示数据与产品数据相结合，并在系统之间交换，目的是接收系统可以构建一个或多个适合人类感知的产品信息图片。产品信息可以通过两种方式可视化：根据射影几何和光传播和反射规则的逼真、栩栩如生的图像，或符合绘图标准和惯例的符号表示。 ISO 10303-46 支持这两种类型的表示。两种可视化过程需要不同类型的图形转换，并且可以将它们组合在同一幅图中。从产品信息及其呈现数据实际生成图片的工作留给接收系统。由于图形系统功能的限制，渲染的描绘可能会偏离理想目标。 [外文原描述]： ISO 10303-46 specifies the integrated resource constructs for Visual presentation. ISO 10303-46 specifies the integrated resources for the visualization of displayable product information. Presentation data as described in ISO 10303-46 are combined with product data and are exchanged together between systems with the aim that the receiving system can construct one or several pictures of the product information suitable for human perception. Product information can be visualized in two ways: either by realistic, life-like images according to the rules of projective geometry and light propagation and reflection, or by symbolic presentations that conform with draughting standards and conventions. ISO 10303-46 supports both types of presentations. The two types of visualization processes require different kinds of graphical transformations and these can be combined in the same picture. The actual generation of the picture from the product information and its presentation data is left to the receiving system. The rendered depiction can deviate from an ideal target because of limitations in the capabilities of graphics systems.
