Differences between revisions 2 and 3

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

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:　旋转的例子: attachment:hpr.py 使用simples/tutorial1中的model
