* 旋转方向 * Heading: XZ平面逆时针转 * Pitch: YZ平面 * Roll: 旋转的例子: attachment:hprtest.py 使用simples/tutorial1中的model == 镜头 == base.camera |
基础
组成结构
- 树型结构
Render -> NodePath -> PandaNode(Geom) [GeomVertexData, GeomPrimitive]
GeomVertexData 保存顶点数据, GeomPrimitive 保存顶点的index
坐标
- render(3d) X右,Y前,Z上 render2d 坐标左下角(-1,0,-1)到右上角(1,0,1)
移动、形变
NodePath.setPos(X,Y,Z) #位移
NodePath.setHpr(H,P,R) #旋转
NodePath.setScale(uniform) #缩放
- 旋转方向
- Heading: XZ平面逆时针转
- Pitch: YZ平面
- Roll:
镜头
- base.camera
