Is It possible to move the avatar programmatically or specify position in Autodesk.AEC.Minimap3DExtension

Deprojection from 2D to 3D is wrong regardless of method

QUESTION

Is It possible to move the avatar programmatically or specify position in Autodesk.AEC.Minimap3DExtension

Asked 2020-Nov-11 at 10:11

Autodesk.AEC.Minimap3DExtension provides a 3d and 2d sync forge viewer where a user can use 2d viewer and move the avatar to navigate. In order to navigate user has to move the avatar or a dot icon in 2d viewer to navigate in 3d model.

My question is where is there any possibility where I can send the set of coordinates which are with me and can I move the avatar programmatically so that user don't have to do so.

here is any example why I am asking so, I have a geometry on my forge viewer which is on 2D and I am looking to make a first person view over that geometry. So If I have all the points of geometry I want to make it use with Autodesk.AEC.Minimap3DExtension so that I can move first person to different views

here is the sample I am rereferring to link

I had been following this wonderful blog link with the help of this I am aware little bit aware how to work with 2dto3d here in above link

I'm glad you like the blog post :)

After reading the question I have the impression that you have already answered it yourself. If you have some kind of a geometry, let's say a polyline, overlaid on top of the 2D drawing, you can use the same logic explained in the blog post, but when calling viewer.hitTest, instead of passing in some mouse coordinates, you would just supply one of the points of your polyline.

QUESTION

Deprojection from 2D to 3D is wrong regardless of method

Asked 2019-Dec-11 at 06:12

I am trying to deproject a 2D image point to a 3D point, and there seems to be just as much misinformation as there is information out there on how to do it. I have the problem modeled in UE4, where I know that:

Camera Location: (1077,1133,450)

Camera Rotation (degrees): yaw = 90, pitch = 345, roll=0

Camera Horizontal FOV (degrees): 54.43224

Camera Vertical FOV (degrees): 32.68799

Camera Shear: 0

Camera Resolution: 1280x720

Object Location in world: (923,2500,0)

Object Location in image frame: (771,427)

From the above data and this method, I have intrinsic camera matrix:

It's just UE4 being odd about the rotation matrix. I modeled the problem in Blender 2.79 and everything works perfectly if you rotate the camera with ZYX (ypr) and add a 180 degree offset to the roll (so 180-reported_angle) in the code.

Upshot is know your engine and how it does or does not conform to published standards!
