MatrixState中的参数与 CP_Na_Cl中参数的比较

MatrixState:

 public static void setInitStack()//获取不变换初始矩阵
    {
    	currMatrix=new float[16];
    	Matrix.setRotateM(currMatrix, 0, 0, 1, 0, 0);
    }
    
    public static void pushMatrix()//保护变换矩阵
    {
    	stackTop++;
    	for(int i=0;i<16;i++)
    	{
    		mStack[stackTop][i]=currMatrix[i];
    	}
    }
    
    public static void popMatrix()//恢复变换矩阵
    {
    	for(int i=0;i<16;i++)
    	{
    		currMatrix[i]=mStack[stackTop][i];
    	}
    	stackTop--;
    }
    
    public static void translate(float x,float y,float z)//设置沿xyz轴移动
    {
    	Matrix.translateM(currMatrix, 0, x, y, z);
    }
    
    public static void rotate(float angle,float x,float y,float z)//设置绕xyz轴移动
    {
    	Matrix.rotateM(currMatrix,0,angle,x,y,z);
    }
    
    public static void scale(float x,float y,float z)
    {
    	Matrix.scaleM(currMatrix,0, x, y, z);
    }
    
    //插入自带矩阵
    public static void matrix(float[] self)
    {
    	float[] result=new float[16];
    	Matrix.multiplyMM(result,0,currMatrix,0,self,0);
    	currMatrix=result;
    }

CP_Na_Cl:


public void drawSelf(){
		
		MatrixState.rotate(roateX, 1, 0, 0);
		MatrixState.rotate(roateY, 0, 1, 0);
		MatrixState.rotate(roateZ, 0, 0, 1);
		
		drawLine(-offset, 1, 1, 1, 1);
		MatrixState.pushMatrix();
		MatrixState.rotate(90, 0, 1, 0);
		drawLine(-offset, 1, 1, 1, 1);
		MatrixState.popMatrix();
		MatrixState.pushMatrix();
		MatrixState.rotate(90, 1, 0, 0);
		drawLine(-offset, 1, 1, 1, 1);
		MatrixState.popMatrix();
		
		drawLine(0, 1, 1, 1, 1);
		MatrixState.pushMatrix();
		MatrixState.rotate(90, 0, 1, 0);
		drawLine(0, 1, 1, 1, 1);
		MatrixState.popMatrix();
		MatrixState.pushMatrix();
		MatrixState.rotate(90, 1, 0, 0);
		drawLine(0, 1, 1, 1, 1);
		MatrixState.popMatrix();
		
		drawLine(offset, 1, 1, 1, 1);
		MatrixState.pushMatrix();
		MatrixState.rotate(90, 0, 1, 0);
		drawLine(offset, 1, 1, 1, 1);
		MatrixState.popMatrix();
		MatrixState.pushMatrix();
		MatrixState.rotate(90, 1, 0, 0);
		drawLine(offset, 1, 1, 1, 1);
		MatrixState.popMatrix();
		
		draw5Big(-offset, 0, 1, 0, 1);
		draw4Small(-offset, 1, 1, 0, 1);
		
		
		
		draw4Big(0, 0, 1, 0, 1);
		draw5Small(0, 1, 1, 0, 1);
		
		
		
		draw5Big(offset, 0, 1, 0, 1);
		draw4Small(offset, 1, 1, 0, 1);
		
		
	}

总结:CP_Na_Cl中的rotatex是在MatrixState中rotate上进行的,rotatex用于计算比较,不过相当于rotate中的X!
