Autocad and Max corrdinate System ?

[Sketchrender]

Hi

I placed a querry last week in relation to the coordinate system in max and got no replies.

 

Can somebody please tell, my why I have to bring a modelin in to autocad or microstation to set up camera positions from OS data, and then import that in into Max.

 

Why can't max do this, the software costs enough it should be able to do it.

Placing a Camera by Coordinates

 

--------------------------------------------------------------------------------

 

Hi

I have received coordinates for a survey with exact camera positions.

eg.

 

Coordinates vp1 E:205563 N:249040 elevation 42.

 

Angle of View

 

Horizontal =30.97 degrees

Vertical =20.65 degrees

 

and camera lens 52mm

 

How do i feed this info in to max.

 

Any help would be gratefull.

 

thanks

phil

 

If nobody can answer this can they point me to somebody who can please.

 

 

thank you in advance

Philip, the camera FOV and lenses can be easily adjusted from within the Camera settings, but I'm not sure how you can input the location coordinates within Max. Are you importing a DEM terrain or any other kind of elevation model you can use for reference into Max ?

perhaps i'm totally wrong, it's just an idea...

in max, you can put a sun to an exact date of the year regards to the position in the globe, can u use this and place your scene and camera instead of the sun?!?!

...if it works tell me...

i was given similar info of camera locations on a previous job in order to produce some photomontages.

 

The GPS data of the camera locations is of course absolute but if you also have GPS data for a location on the site it is possible to calculate the cameras position relative to the site. Having done this i placed location nodes in my AutoCAD model and imported them into viz/max and just snapped the cameras to the appropiate nodes. Which sounds similar to the method you have used.

 

i don't see why you can't input the values directly in max, but inorder to for these points to be correct in relation to your model, the model would also have to be located at the correct GPS location (most likely a very long way away from 0,0,0). When using max i think generally people import their model to a postion of 0,0,0 as panning, zooming and rendering solutions are most accurate at this point, hence the camera locations now become relative to the site rather than absolute to GPS data.

 

I'm not sure how correct this assumption is (it may be completely wrong) but its the answer that springs to mind for me!!
