Question

我正在尝试使用forxMotionTracker为openframeworks添加。我在linux 64架构的代码块中构建它。

构建它时，我在ofCircleSlice.cpp

中遇到了编译错误

void ofCircleSlice(float x,float y, float radius, float lowAngle, float highAngle, bool closed, bool radians){

if (!bSetupCircle) setupCircle();

// use smoothness, if requested:
if (bSmoothHinted && drawMode == OF_OUTLINE) startSmoothing();

bool angleWrap = (lowAngle > highAngle); // are we doing the 0/360 wrap?

if(!radians){
    lowAngle = ofDegToRad(lowAngle);
    highAngle = ofDegToRad(highAngle);
}

int res = numCirclePts;
float angle = lowAngle;
float angleRange = ((!angleWrap)?(highAngle - lowAngle):(M_TWO_PI - lowAngle + highAngle));
float angleAdder = angleRange / (float)res;
int k = 0;
for (int i = 0; i < numCirclePts; i++){
    circlePtsScaled[k] = x + cos(angle) * radius;
    circlePtsScaled[k+1] = y - sin(angle) * radius;
    angle += angleAdder;
    k+=2;
}
// we draw the circle points ourself (vs. glDrawArrays) because it allows us to draw the center point, and have the triangles fan around it
k = 0;
glBegin((drawMode == OF_FILLED) ? GL_TRIANGLE_FAN : (closed?GL_LINE_LOOP:GL_LINE_STRIP));
glVertex2f(x, y); // center vertex

// now all the points around the circumference
for (int i = 0; i < numCirclePts; i++){
    glVertex2f(circlePtsScaled[k], circlePtsScaled[k+1]);
    k+=2;
}
glEnd();

    // back to normal, if smoothness is on
    if (bSmoothHinted && drawMode == OF_OUTLINE) endSmoothing();
};

获得的错误是：

我错过了一些非常明显的东西。感谢

用以下代码替换了CircleSlice函数

  ofPath tArcPath;
tArcPath.setArcResolution(360);
tArcPath.arc(x, y, radius, radius, lowAngle, highAngle);
tArcPath.draw();

没有构建错误＆amp;工作得很好
