Abstract: An image processing apparatus is provided. A splitting unit of the image processing apparatus may split a first space within an input three-dimensional (3D) model into a plurality of subspaces in order to generate an acceleration structure of the input 3D model. A decision unit of the image processing apparatus may set a subspace determined as having a relatively high probability of including a ray progress path among the plurality of subspaces, as a child node having a relatively high traversal priority in the acceleration structure among a plurality of child nodes.

Abstract: An image rendering apparatus may include a buffer memory unit and a processor. The buffer memory unit may store input ray data for image rendering according to a ray tracing scheme while shape data corresponding to the input ray data is being fetched from a cache. The processor may output the received shape data together with the input ray data to an operation apparatus.

Abstract: Provided is an image processing apparatus. The image processing apparatus may perform an intersection test for rendering of a ray tracing scheme. The image processing apparatus may include a first calculator and a second calculator. The first calculator may perform a ray-plane test to determine whether a ray intersects a plane including a primitive and a barycentric test to determine whether the ray intersects the primitive. The second calculator may calculate a hit point based on the ray which intersects the primitive.

Abstract: A rendering method, medium and apparatus for sequentially performing one or more third raster operations to test whether a fragment can be displayed as a pixel after sequentially performing one or more second raster operations to test whether the fragment can be displayed as the pixel, so as to provide efficient power consumption and rapid completion of rendering.
