Intel® Embree is a collection of high-performance ray tracing kernels,
|
|
developed at Intel. The target users of Intel® Embree are graphics
|
|
application engineers who want to improve the performance of their
|
|
photo-realistic rendering application by leveraging Embree's
|
|
performance- optimized ray tracing kernels. The kernels are optimized
|
|
for the latest Intel® processors with support for SSE, AVX, AVX2, and
|
|
AVX-512 instructions.
|
|
|
|
Intel® Embree supports runtime code selection to choose the traversal
|
|
and build algorithms that best matches the instruction set of your CPU.
|
|
We recommend using Intel® Embree through its API to get the highest
|
|
benefit from future improvements. Intel® Embree is released as Open
|
|
Source under the Apache 2.0 license.
|
|
|
|
Intel® Embree supports applications written with the Intel® SPMD Program
|
|
Compiler (ISPC, https://ispc.github.io/) by also providing an ISPC
|
|
interface to the core ray tracing algorithms. This makes it possible to
|
|
write a renderer in ISPC that automatically vectorizes and leverages
|
|
SSE, AVX, AVX2, and AVX-512 instructions. ISPC also supports runtime
|
|
code selection, thus ISPC will select the best code path for your
|
|
application.
|
|
|
|
Intel® Embree contains algorithms optimized for incoherent workloads
|
|
(e.g. Monte Carlo ray tracing algorithms) and coherent workloads (e.g.
|
|
primary visibility and hard shadow rays).
|
|
|
|
The single-ray traversal kernels of Intel® Embree provide high
|
|
performance for incoherent workloads and are very easy to integrate into
|
|
existing rendering applications. Using the stream kernels, even higher
|
|
performance for incoherent rays is possible, but integration might
|
|
require significant code changes to the application to use the stream
|
|
paradigm. In general for coherent workloads, the stream mode with
|
|
coherent flag set gives the best performance.
|
|
|
|
Intel® Embree also supports dynamic scenes by implementing
|
|
high-performance two-level spatial index structure construction
|
|
algorithms.
|
|
|
|
In addition to the ray tracing kernels, Intel® Embree provides some
|
|
Embree Tutorials to demonstrate how to use the Embree API.
