我尝试使用 OpenGL 非对称平截头体平行轴投影绘制 3D 点云。一般原则可以在这个网站上找到（http://paulbourke.net/stereographics/stereorender/#）。但是现在的问题是，当我使用真正的眼睛分离（0.06m）时，我的眼睛融合得不好。当使用眼睛分离 = 1/30 * 焦距时，没有压力。不知道是计算有问题，还是参数有问题？部分代码贴在下面。谢谢你们。

for view = 0:stereoViews
    % Select 'view' to render (left- or  right-eye):
    Screen('SelectStereoDrawbuffer', win,  view);

    % Manually reenable 3D mode in  preparation of eye draw cycle:
    Screen('BeginOpenGL', win);

    % Set the eye seperation:
    eye = 0.06; % in meter

    % Caculate the frustum shift at the near plane:
    fshift = 0.5 * eye *  depthrangen/(vdist/100);  % vdist is the focal length, 56cm, 0.56m
    right_near = depthrangen *  tand(FOV/2); % depthrangen is the depth of the near plane, 0.4. %FOV is the field of view, 18°
    left_near = -right_near;
    top_near = right_near* aspectr;
    bottom_near = -top_near;

    % Setup frustum projection for this  eyes 'view':
    glMatrixMode(GL.PROJECTION)
    glLoadIdentity;
    eyeside = 1+(-2*view); % 1 for left eye, -1 for right eye
    glFrustum(left_near + eyeside *  fshift, right_near + eyeside * fshift,  bottom_near, top_near, %depthrangen,  depthrangefObj);         

    % Setup camera for this eyes 'view':
    glMatrixMode(GL.MODELVIEW);
    glLoadIdentity;
    gluLookAt(0 - eyeside * 0.5 * eye, 0,  0, 0 - eyeside * 0.5 * eye, 0, -1, 0, 1, 0);
    
    % Clear color and depths buffers:
    glClear;
    moglDrawDots3D(win, xyz(:,:,iframe),  10, [], [], 1);
    moglDrawDots3D(win,  xyzObj(:,:,iframe), 10, [], [], 1);

    % Manually disable 3D mode before  calling Screen('Flip')!
    Screen('EndOpenGL', win);
    % Repeat for other eyes view if in stereo presentation mode...
end
