I write a article about how to create a local coordinate system for a dependent 3d model, LOCAL COORDINATE SYSTEM We can real value in world coordinate system of vector or point on 3D model. For example, I want to Read more…
We want to know the world coordinate of a point on a 3D widget event though we don’t know the widget’s position on the world coordinate system. I get a matrix from an actor and create a temporal vtkTransform object, Read more…
notes ${} 和 $[] $[expression] can calculate easily. ${expression} can tell us the value of a element in array. eg val1=23 val2=24 echo $val1+$val2 echo $[$val1+$val2] #it is equal to `echo $(( $val1+$val2 )` [edemon@CentOS workspace]$ ./incalc.sh 23+24 47 assign Read more…
