 # Cool Patches: A Geometric Approach to Ray/Bilinear Patch Intersections

  ![](/sites/default/files/styles/wide/public/publications/chapter8-rep-image_0.png?itok=ZKI4KPEz)

 We find intersections between a ray and a nonplanar bilinear patch using simple geometrical constructs. The new algorithm improves the state of the art performance by over 6X and is faster than approximating a patch with two triangles.
