节点动画

功能概述

在3D场景中可以配置动画,让3D场景的表现更加丰富。下图是数据预警的动画,当数据达到阈值时,绑定数据的物体会运行预警动画



在开始介绍如何创建、使用动画之前,我们先了解一下3D场景中有关动画的一些基本概念

1. 动画面板

在3D场景设计器左边,打开动画面板,在这里你可以查看、新建、复制、删除动画。

  • 新建动画

  • 复制动画

  • 删除动画

  • 禁用动画或启用动画

image-12

2. 动画类型

3D场景支持3种动画类型:

  • 模型内置动画

  • 模型节点动画

  • 数据图层动画

每一种动画都可以定义执行的时机,支持场景加载完成后立即执行,也可以基于实时数据进行判别执行。节点动画和数据图层动画支持动画的目标来自实时的数据绑定,例如移动动画,可以移动到某一个绑定的实时数据。

3. 模型内置动画

模型内置动画是通过设定相关配置,运行3D模型自带的动画。

添加内置动画

操作步骤


打开动画面板

添加一个模型内置动画

打开3D场景设计器右侧的属性设置面板,

配置动画的相关设置

image

设置选项

设置

描述

动画名称

设定动画的名字,该名字在整个3D场景中唯一不可重复。

内置动画

选择要运行的某个模型的一个动画

内置动画列表会显示当前3D模型的内置动画,如果没有无法构建内置动画。

循环模式

(详见 动画循环模式

延迟执行(秒)

在满足执行时机后,等待设置的时长(秒)后才运行动画

image-5

执行时机

支持两种时机:场景加载完成,满足设置的条件(详见 动画执行时机设置

4. 模型节点动画

模型节点动画是给3D场景中某一个具体的节点设置动画

设置选项

6. 动画循环模式

3D 场景中的动画一共有3种循环模式:

循环模式

描述

单次

在到达动画结束值(目标值)时,停止动画。

单次模式还可以配置以下设置,是否保留结束时状态

image-9

  • 是:在到达动画结束值时,模型节点保持当前状态

  • 否:在到达动画结束值时,模型节点恢复到初始状态

重复

在到达动画结束值时,立即从初始状态重新启动动画

循环

在到达动画结束值时,将反转其方向到初始值,而不是从头开始

示例

物体从 A 点 移动到 B 点,动画时长都设置为4秒

描述

目标值是否支持数据绑定


改变颜色

改变节点蒙层颜色

image-13

隐藏

隐藏节点


移动

移动节点到指定位置

image-14

移动(偏移)

根据设定的偏移量移动节点

image-15

旋转

旋转节点到指定角度

image-16

缩放

根据设定的缩放倍数缩放该节点

image-17

7.2 目标值设置

某些动画类型的目标值支持两种数据设定:固定值和动态数据。

对于不同的动画类型,动态数据的来源设置也不一样:

  • 模型节点动画:可以自由选择数据模型和字段

  • 数据图层动画:只能选择在该数据图层中已经绑定好的数据字段

示例:设置一个节点(小车)通过实时数据进行移动

步骤

描述


1

创建一个数据图层,设置关联的数据集 (例如小车位置实时数据)

image-21

2

设置数据集自动刷新定时刷新实时刷新

image-18

3

添加一个模型节点动画

image-19

4

设置节点名称:输入想要移动的物体名称,例如“小车”

5

设置循环模式:单次

6

设置保存结束时状态:

7

动画类型:移动

8

位移:动态数据

在弹出的对话框里设置动态数据

image-20

如果x/y/z 某个移动方向没有设置数据绑定,则在该方向,会使用节点当前值。

例如:小车只在x方向移动,只需要设置 x 字段,y和z无需设置。

9

点击确定保存动态数据设置


10

切换到预览模式,现在小车就会根据每次收到的数据移动到对应的位置。


8. 动画执行时机设置

动画支持两种执行时机

  • 场景加载完成:在运行时,当场景加载完成后,立即执行该动画

  • 满足条件:当满足设置的条件时,执行该动画,通常会选择绑定的实时数据

8.1 场景加载完成执行

场景模型加载完成后,立即执行该动画。

8.2 满足条件执行

满足特定的数据条件,来执行动画。
