US20160071310A1 - Beam tracing - Google Patents

    https://patents.google.com/patent/US20160071310A1/en
    An apparatus, computer readable medium, and method are disclosed for performing an intersection query between a query beam and a target bounding volume. The target bounding volume may comprise an axis-aligned bounding box (AABB) associated with a bounding volume hierarchy (BVH) tree. An intersection query comprising beam information associated with the …

Nonlinear Beam Tracing on a GPU - Microsoft Research

    https://www.microsoft.com/en-us/research/publication/nonlinear-beam-tracing-on-a-gpu/
    Nonlinear beam tracing is highly challenging because commodity graphics hardware supports only linear vertex transformation and triangle rasterization. We overcome this difficulty by designing a nonlinear graphics pipeline and implementing it on top of a commodity GPU. This allows beams to be nonlinear where rays within the same beam do not ...

    the classic ray trace and creates output that can directly drive image space rendering programs. 2. Beam Tracing The beam tracer is a recursive polygon hidden sur- face algorithm. The hidden surface algorithm is designed to find all visible polygons within an …

Beam tracing for two- and three-dimensional problems in …

    Beam tracing is an extension of ray tracing that constructs beams around the central rays radiating from a source. Typically, a fan of such beams is used to represent a point source and the field at any given location is computed by coherently summing all contributing beams. On a slightly superficial

Accelerated beam tracing algorithm - ScienceDirect

    https://www.sciencedirect.com/science/article/pii/S0003682X07001910
    The beam tracing technique is an optimal solution to the problem of finding the early specular reflections, because it produces exactly the same results as the image source method, but optimizes the visibility calculation so that only image sources which are part of a valid reflection path are considered .

    Beam tracing is an extension of ray tracing that constructs beams around the central rays radiating from a source. Typically, a fan of such beams is used to represent a point source and the field at any given location is computed by coherently summing all contributing beams. On a slightly superficial level, one points to the following key ...

    D. Beam tracing methods Beam tracing methods27,28 classify propagation paths from a source by recursively tracing pyramidal beams ~i.e., sets of rays! through the environment ~see Fig. 4!. Briefly, for each beam, polygons in the environment are considered for intersection with the beam in front-to-back visibility or-tracing,

    The beam tracing technique is an optimal solution to the problem of finding the early specular reflections, because it produces exactly the same results as the image source method, but optimizes the visibility calculation so that only image sources which are part of a valid reflection path are considered [19].
