GDL - 2 moving angle hotspots in one place

Domagoj Lukinic — Thu, 26 Sep 2024 11:32:07 GMT

Hello everyone

I am making a GDL based camera with changeable geometry, projection, ect.

I have 2 variables hr & vr (Horizontal rotation & Vertical rotation)

and I want moving hotspots to be set in the same position.

Can you please tell me what am I doing wrong?

I know that you can do that kind of thing in 2d for text for "free movement" witch I have done, is it even possible to do that kind of thing for angle, if no I was trying to set hotspots in the same plane like hr is (0,1,0) and vr is (0,2,0) But I am having troubles with planes of rotation for example (vr) needs to be on my vatical plane and hr on horizontal, but horizontal in on vertical plane...

here is my chuck of code for rotation:

add 0,-bcmd1/2,-bcmd1/2 block bcml1,bcmd1,bcmd1 del 1 add bcml1,-bcmd2/2,-bcmd2/2 block bcml2,bcmd2,bcmd2 del 1 addx bcml ! ------------------------------------------------------------------------------ ! HOTSPOTS ! ------------------------------------------------------------------------------ unID=0 !--- BASE HOTSPOTS ---! hotspot bcrhl+bcol,0,0,unID,vr,4+128,vr :unID=unID+1 !BASE FOR VR hotspot bcrhl+bcol,0,0,unID,hr,4,hr :unID=unID+1 !BASE FOR HR rotz hr roty vr !--- Vertical rotation (vr) ---! hotspot bcrhl,0,0,unID,vr,5,vr :unID=unID+1 !MOVEING hotspot 0,0,0,unID,vr,6,vr :unID=unID+1 !CENTAR hotspot bcrhl+bcol,bch,0,unID,vr,7,vr :unID=unID+1 !REFERENCE !--- Horizontal rotation (hr) ---! hotspot bcrhl,0,0,unID,hr,5,hr :unID=unID+1 !MOVEING hotspot 0,0,0,unID,hr,6,hr :unID=unID+1 !CENTAR hotspot 0,bcrhl+bcol,0,unID,hr,7,hr :unID=unID+1 !REFERENCE add -bcbd/2,-bcbd/2,-bcbd/2 block bcrhl+bcbd/2,bcbd,bcbd del 1 add bcrhl,-bcw/2,-bch/2 block bcl,bcw,bch del 4

Thank you in advance!

Wrong type of hotspot? Angle Hotspots should have 4 nodes. Center, moving, base, reference. Ideally, they would also include a Cosine function to keep the hotspots position consistant relative to the inputted rotation.

From one of my objects:

hotspot ProWidth / 2, 0, 0, unID, ProPitch, 6 :unID = unID + 1 !Bottom Left center hotspot ProWidth / 2, 0, ProLength, unID, ProPitch, 5 :unID = unID + 1 !moving hotspot ProWidth / 2, 0 - ProLength * sin (phi), ProLength - (2 * ProLength * sin (phi / 2)) * cos ((180-phi)/2), unID, ProPitch, 4+128 :unID = unID + 1 !base hotspot ProWidth / 2, 0, 0, unID, ProPitch, 7 :unID = unID + 1 !Top Right center

If you are wanting both your horizontal and vertical hotspot to overlap, you would need to include the trig functions in both your x and y parameters.
