camupm

Set camera up vector using geographic coordinates

Syntax

camupm(lat,long)
[x,y,z] = camupm(lat,long)

Description

camupm(lat,long) sets the axes CameraUpVector 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] = camupm(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. Set CameraUpVector to the antipode of the camera target for that down under view:

figure
axesm('globe','galt',0)
gridm('glinestyle','-')
load topo
geoshow(topo,topolegend,'DisplayType','texturemap');
demcmap(topo)
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)
land = shaperead('landareas.shp','UseGeoCoords',true)
linem([land.Lat],[land.Lon])
axis off
