    We present a micropolygon ray tracing algorithm that is capable of efficiently rendering high quality defocus and motion blur effects. A key component of our algorithm is a BVH (bounding volume hierarchy) based on 4D hyper-trapezoids that project into 3D OBBs (oriented bounding boxes) in spatial dimensions.

    shading evaluations for efficient micropolygon ray tracing. Com-pared to the state-of-the-art micropolygon ray tracing algorithm, our method is able to reduce the required shading evaluations by an order of magnitude and achieve significant performance gains. 1.1 Related Work Extensive research has been done on micropolygon rendering and ray ...

    Micropolygon and Ray Trace engines take a bit of work to get realistic images although with the advent of high dynamic range image maps and somewhat efficient ambient occlusion schemes and in Houdini 10's path tracing enhancements, it is easier to achieve the goal if realistic renders. You can also simulate irradiance and global illumination ...

Psychopath Renderer

    https://psychopath.io/post/2014_06_26_ray_tracing_micropolygons
    I'd like to write about some of that stuff, so for starters I'm going to make a few posts covering how Psychopath's ray tracing kernel has evolved so far. As I mentioned in my first post, I started Psychopath with the goal of building a proof-of-concept micropolygon path tracer. From the very beginning that goal guided me to make some atypical ...

    The following might be reasons to use the micropolygon rendering engine: Scenes involving a lot of fur and/or smoke (using deep shadow maps), or sprites, can render more efficiently with micropolygon rendering, provided you are not using ray traced shadows or other ray tracing in the shader. Note that you might want to render fur and volumes as ...

    A micropolygon ray tracing algorithm was recently added to the system to efficiently render defocus, motion blur, and secondary ray effects. GPGPU debugger: a new framework for debugging GPU stream programs, which is based on GPU Interrupt, a new mechanism that allows calling CPU functions from GPU code.

Path Tracing vs Ray Tracing - Dusterwald.com

    Of course faking always requires more time and skill on the side of the artist so eventually this won’t be needed, but until path tracing times are measured in minutes per frame, as opposed to the hours or days they are now, ray tracing (or rasterization, especially micropolygon rasterizers like the one powering RenderMan) remains the better ...

Micropolygon - Wikipedia

    https://en.wikipedia.org/wiki/Micropolygon
    In 3D computer graphics, a micropolygon (or μ-polygon) is a polygon that is very small relative to the image being rendered. Commonly, the size of a micropolygon is close to or even less than the area of a pixel. Micropolygons allow a renderer to create a highly detailed image. The concept of micropolygons was developed within the Reyes ...
