SUMMARY

The discussion centers on determining the radius of a sphere based on known camera rotation values in a 3D space. The user seeks to calculate the intersection point of the sphere's z-axis with a tangent plane, given the rotation parameters around the x, y, and z axes. The key takeaway is that while rotation values provide orientation, they do not directly yield the sphere's radius without additional geometric relationships or measurements.

PREREQUISITES
  • Understanding of 3D geometry and spatial transformations
  • Familiarity with camera projection techniques
  • Knowledge of spherical coordinates and their applications
  • Experience with image warping and mapping techniques
NEXT STEPS
  • Research geometric relationships in 3D space involving spheres and planes
  • Explore camera projection models and their impact on 3D rendering
  • Learn about spherical coordinate systems and their conversions
  • Investigate image warping algorithms and their mathematical foundations
USEFUL FOR

3D graphics developers, computer vision engineers, and anyone involved in image processing and spatial analysis.

Hello,
I have a sphere (actually an image warping a sphere) I know the rotation values,
can I get the sphere radius by these parameters ?
 
Physics news on Phys.org
What do you mean by "rotation values"?
 
I have an image projected on a plane tanget to a sphere, I know the camera rotation values over x,y,z... I need the sphere radius inorder to know where the z axis (of the sphere) intersects with the plane (I can assume its (0,0,Z) , x,y =0, but I need Z).
Thanks
