开始

上次玩了动画
可以把动画流程总结一下吗?

还原场景

设置动画

为人物增加关键帧

帧号	location
1	(0,0,0)
10	(10,0,0)

man.location = (0, 0, 0) 
man.keyframe_insert(data_path="location", frame=1)  
man.location = (10, 0, 0)
man.keyframe_insert(data_path="location", frame=10)

在layout视图中观察到
- 关键
- 人物动画

能动了吗?

观察

在layout工作区
- 观察man的时间轴
- 确实有关键帧

能渲染出来吗

设置渲染

切回Script工作区
- 设置渲染动画

def render():
    bpy.context.scene.frame_end = 10
    bpy.context.scene.render.resolution_x = 200
    bpy.context.scene.render.resolution_y = 150
    bpy.context.scene.render.resolution_percentage = 50
    bpy.context.scene.render.engine = 'CYCLES'
    bpy.context.scene.render.filepath = "/home/shiyanlou/Code/o"
    bpy.ops.render.render(animation=True)

点击运行按钮
- 渲染起来

安装序列查看工具

feh /home/shiyanlou/Code

最终效果
- 人物动了
- 跑黑影里了

下面准备
- 让灯光追踪角色

添加约束

选中聚光灯spot
- 约束调板
- 添加对象约束

设置约束

约束类型为
- Track to

将Track To目标
- 设置为man

并设置z轴负向
- 指向man

约束效果

开启实时渲染模式

在layout工作区

将上述工作转化为代码

问题

feh /home/shiyanlou/Code

观察序列效果

摄影机没跟上

初始帧

在layout工作区
- 选中摄影机
- 在第1帧
- 设置rotation属性为关键帧

调试摄影机

开启 4视图模式

调整视图

将播放头移动到第10帧
- 并将透视图设置为
- 摄影机看到的画面

调整旋转

在保证
- 摄影机位置不变的基础上
- 调整摄影机的旋转角度
  - 蓝色轴控制z轴旋转
  - 红绿轴控制xy轴旋转

观察最终位置
- 并代码化

代码化

相应代码

再观察

feh /home/shiyanlou/Code

观察序列效果
- 灯光和摄影机
  - 都开始跟着角色了

可以把镜头
- 推上来吗?

摄影机镜头推焦距

名称	时长
起幅	10帧
镜头焦距推	10帧
落幅	10帧

将视图
- 从4视图
- 还原为单一视图

观察摄影机焦距
- 50mm
尝试推镜头

推镜头

将镜头焦距
- 设置为70 mm
- 观察效果

将推镜头代码化
