In 3D plot, how do I set the vertical axis to be y-axis down, z-axis forward and x-axis right?
古いコメントを表示
My hybrid 3D curves and images were drawn together, and I initially succeeded in drawing the result I wanted below, but the only thing missing was the y-axis and z-axis orientation. how do I set the vertical axis to be y-axis down, z-axis forward and x-axis right?(i.e. the physical coordinate system of the camera),your answer would be great appreciately!
%% x,y,z axis is located origin

hAxis = gca;
hAxis.XRuler.FirstCrossoverValue = 0; % X crossover with Y axis
hAxis.XRuler.SecondCrossoverValue = 0; % X crossover with Z axis
hAxis.YRuler.FirstCrossoverValue = 0; % Y crossover with X axis
hAxis.YRuler.SecondCrossoverValue = 0; % Y crossover with Z axis
hAxis.ZRuler.FirstCrossoverValue = 0; % Z crossover with X axis
hAxis.ZRuler.SecondCrossoverValue = 0; % Z crossover with Y axis
hAxis.Parent.Color=[1,1,1];
view(3);
box off;grid off;hold on;
%% space curve
t = -300:.1:400;
y = 200*sin(t/30);
z = 200*ones(size(t));
plot3(hAxis,t,y,z)
axis([-300,600,-300,600,0,200])
%% space image
img = imread("peppers.png");
image(hAxis,img)
%% adjust to show axes label
xlabel("x");ylabel("y");zlabel("z")
hAxis.YDir="reverse";
hAxis.ZDir = "reverse";
hAxis.XAxis.Label.Position=[hAxis.XLim(end),0,0];
hAxis.YAxis.Label.Position=[0,hAxis.YLim(end),0];
hAxis.ZAxis.Label.Position=[0,0,hAxis.ZLim(end)];
hAxis.LabelFontSizeMultiplier=3;
NOTES:
The following rendering should be oriented like the red arrow I drew by hand,not black,(The default rotation has the z-axis facing forward instead of the default z-axis vertical, just like matlab's built-in functions pcshow, pcplayer, etc. have the verticalAxis property to control the axis orientation)

So what's wrong? Looks like the orientation described to me...what am I missing?

Use the rotate3d tool to move the axes orientation until it looks good. The azimuth and elevation are shown as you rotate. Once it's ok, you can use those azimuth and elevation values in view() to reproduce the orientation programmatically.
