c++ - Set of efficient 3D intersection algorithms

Question

Anyone knows a source, website where I can get some good implementations of 3D intersection algorithms, like

• intersection of sphere and sphere
• sphere/ellipsoid
• sphere/cuboid
• ellipsoid/ellipsoid
• ellipsoid/cuboid
• cuboid/cuboid
• sphere/ray
• ellipsoid/ray
• cuboid/ray
• triangle/ray
• quad/ray
• triangle/triangle
• quad/quad
