Abstract: A parallel processing drawing method operable on a computing device, such as a mixed- or virtual-reality head-mounted display (HMD) device, is utilized to provide a drawing tool that enables a user to virtually draw a line on a mesh of primitive geometric objects (e.g., triangles) that model three-dimensional (3D) surfaces of virtual or real-world objects. A device user provides inputs to a user interface on the computing device to virtually draw a line that the drawing tool then renders on a display system. The parallel processing drawing method simultaneously computes each of the individual line segments to conform the virtually drawn line to the mesh. The method is computationally efficient compared to conventional ray tracing which facilitates applications such as quick marking and drawing on meshes including complex meshes representing terrain and irregularly shaped objects.
