zScale / translateZ? #4

Closed heaversm closed 12 years ago

heaversm commented 12 years ago

Hi - I'm trying to export only a certain z depth to OBJ and I noticed that you have some code in your file that controls zScale and translateZ, but that doesn't seem to have any visual effect within the editor - is this feature set up?

I noticed that within depthToObjExporter.h I can replace 

//obj << "v " << r.x << " " << -r.y << " " << -r.z << endl;

with

if (r.z > 400 && r.z < 1100){ //MH - capture only certain z depth
  obj << "v " << r.x << " " << -r.y << " " << -r.z << endl; 
}

but I'd like to be able to set it visually / dynamically.

the transZ is implemented and working. It works with up arrow key and down arrow key. The scaleZ is implemented as well butI disabled it because I no longer needed it because using the calibrated data fixed the z scale. https://github.com/roymacdonald/kinectToTexturedOBJ/blob/master/src/testApp.cpp#L76 if you uncomment it should also work, but note that it is just for vizualization.

Thanks - can you clarify what transZ's function is? It doesn't seem to have any effect within the visual editor itself.

it moves the center of the point cloud. you'll notice the difference while rotating.
