Camera up vector in geographic coordinates
Syntax
camupm(lat,long) [x,y,z] = camupm(lat,long)
Description
camtargm(lat,long) sets the axesCameraUpVector property of the current map axes to the position specified in geographic coordinates. The inputs lat and long are assumed to be in the angle units of the current map axes.
[x,y,z] = camtargm(lat,long) returns the camera position in the projected Cartesian coordinate system.
Examples
Look at northern Australia from a point south of and one Earth radius above New Zealand. SetCameraUpVector to the antipode of the camera target for that down under view:
figure; axesm('globe','galt',0); gridm('glinestyle','-')
load topo; meshm(topo,topolegend,size(topo)); demcmap(topo)
displaym(worldlo('POline'))
camlight; material(0.6*[ 1 1 1])
plat = -50; plon = 160; tlat = -10; tlon = 130;
[alat,alon] = antipode(tlat,tlon);
camtargm(tlat,tlon,0); camposm(plat,plon,1); camupm(alat,alon)
set(gca,'CameraViewAngle',80)
