Hotspot in 3d from 0 start angle - wrong plane

Anonymous — Tue, 18 Jul 2017 04:46:16 GMT

Hello!)

I place hotspot points in 3d to angle edition.
Base (4) and Moving (5) points has same coords.
Because on start editing, variable Delta1Angle3D must be changed from 0 to other value.

HOTSPOT 0, 0, 0, unID, Delta1Angle3D, 6 : unID = unID+1
HOTSPOT X, Y, Z, unID, Delta1Angle3D, 4+128 : unID = unID+1
HOTSPOT X, Y, Z, unID, Delta1Angle3D, 5 : unID = unID+1
HOTSPOT X1X, Y1Y, Z1Z, unID, Delta1Angle3D, 7 : unID = unID+1

I specify reference point (7) on right plane. But anyway editing going in wrong plane (red arrow on picture).
But I need to editing on plane with blue arrow (by points 6,4,7)

Help me please ((.

Is this what you want - a rotating hotspot in the X-Y plane?

rad = 0.350
HSID = HSID +1
hotspot 0, 0, 0, HSID, Delta1Angle3D, 6			!center of angle
HSID = HSID +1 
hotspot rad, 0, 0, HSID, Delta1Angle3D, 4+128			!base hotspot
HSID = HSID +1
hotspot rad * cos(Delta1Angle3D), rad * sin(Delta1Angle3D), 0, HSID, Delta1Angle3D, 5		!moving
HSID = HSID +1
hotspot 0, 0, 1, HSID, Delta1Angle3D, 7			!center of angle
HSID = HSID +1

No, not X-Y plane.
This is plane in 3d window by 3 points (in the picture) - (№6,№4,№7)

If you are trying to move X, Y and Z all at the same time I am pretty sure that is not possible.
3D hotspots can only move in one plane at a time as far as I know.

On picture showed - moving goes, but on wrong plane (red arrow).
Usually plane specified by 3 points -
- base (type4)
- center (type 6)
- moving (type 5)

But if on start moment, base = moving (need change angle from 0 to ...)
And in this case plane positon on interactive moving is bad.
Because for specify plane - two points is too few.

I am a little confused as to what you are trying to do.

Your hotspots are adjusting a parameter called "Delta1Angle3D" but you are moving hotspots with X, Y & Z values and your reference is X1X, Y1Y & Z1Z.
What is the relation of X, Y, Z, X1X, Y1Y & Z1Z with the angle parameter?

Point 6 is the centre.
Point 4 is the starting point (base).
Point 5 is the point you are trying to move.

These 3 points should all be in the same plane.

Point 7 should be a point that is perpendicular to that plane.
(or maybe it defines the angle of the plane - I usually just do it flat in the X-Y plan and ROT the whole routine if need be).

At least this is the way I have always understood it to be.

From the GDL manual...

The plane of the angle is perpendicular to the
vector that goes from the center hotspot to the reference hotspot.

Thank you so much!))).

I do not properly set the reference point.
In 3d it's on the perpendicular plane should be.
Now it worked!)))
What a joy.

Thanks again!

Glad you got it working.
I am still not sure how, unless you have extra script that forms a relationship between all your variables (converting the x,y,z, to and angle or vice versa).
