Rotations of Camera

Post by peppemath » Mon Jul 09, 2018 10:07 am

I have a problem: in general, the position of the axes is x to the right, y to the top and z to the monitor. I would like to make the rotations to get the position shown in the figure;

theoretically it would be simple with two rotations of the yz plane and the xy plane of 90 degrees respectively, but it is not. I tried with the PredefiniteCamera positions, I tried to manually enter the values, I tried to use the movements with the mouse, but it is impossible.

Could you give me help?

LightningChart is using some rotation order / style. This leads to a problem that for the certain angles there is no solution. Camera especially sensitive (i.e. Euler angles are invalid) then X or Y being equal 90. We are aware about those limitations and planning to modify our internal calculations. However, this is long-term plan.
As for now, the best workaround is to use angles slightly off, e.g. 89. I believe orientation you are looking should be achieved with RotationX=0, Y=89, Z=90.

Hope this helps.

Hello,

LightningChart v8.4.1.4001 was just released. It contains a lot of new features, improvements and error fixes.
One of improvements that now Chart renders properly on all 3D camera angles.

Happy charting.
