How To Get Started With Optix7

How To Get Started With Optix7 – This post is long overdue – I’ve already mentioned/alluded to OWL in previous posts (in fact, we’ve already used it in many articles), but we haven’t published or written about it yet: First, I want to write about this before it’s ‘ready’ for consumption general; Later on, I got too busy

OWL for my own projects…the more we work with it and the more features it supports, the harder it is to find a good place to start talking about it.

In any case; I finally selected OWL as version 1.0 last week, so it’s time to write a little bit about it.

OWL, as the title of this article suggests, is a “node graph” abstraction layer on top of OptiX 7. To be clear, OWL is.

The “renderer” on top of OptiX (eg PRBT) and not the real-time “rendering engine” on top of OptiX 7 (eg OSPRay is the one on Embree); Instead, its sole purpose is to take all the features of OptiX 7.x and add a little “magic” on top of it in order to:

A type of RTX “Ninja” level practitioner who can figure out the correct data layout and order of Shader Binding Table (SBT) elements at 3 AM. Someone recently described OWL as “training wheels for using RTX”; And although I think it’s more than that, it’s still a pretty good picture.

Dream about SBTs at night (yeah, yeah, I know…) – by automating some of the things that should be done in any OptiX software, but the user really doesn’t have to do.

Interest in things like building SBT, accelerator structures, etc. By simplifying some of the user’s most common (but time-consuming and error-prone) tasks, the user can focus on what they have.

It wants (the shaders that implement the renderer!), not the maintenance and feeding of device buffers, accelerator structures, and SBTs. For example, once all the geometries and groups are created, creating a binding shadow table in OWL (even if you don’t know what it is) is as easy as calling ‘owlBuildSBT()’.

Now before I go into more detail, here are some typical photos taken with OWL over the past few weeks…. Or as I should say correctly, images that are ‘displayed with

If you wanted to write a GPU ray tracing device a few years ago, you had two options: either use OptiX, or write your own in CUDA. Today, thanks to hardware ray tracing, you not only have faster ray tracing, but you also have more options where you can use DirectX Ray Tracing or Vulkan Ray Tracing. With all this choice, the question is why one needs more of this.

To fully understand why anyone would need something like OWL, it pays to go back to OptiX

RTX and OptiX 7 appeared: in the beginning – and up to version 6.5 – OptiX was a high-level abstraction library that was very easy to get hold of.

Go quickly by typing in the closest, desired, desired software, ray-gen, etc., then specify some “attributes”, “buffers” and “variables” in the device code that the programs can use. One can create a simple nodal graph on the host (which defines, for example, trigonometric networks and velocity structures), set some variables to define application parameters and device side geometry, and it’s done. Of course, it still takes

It’s time to wrap your head around the purpose of all these programs and how to theoretically map your beam to the x-ray generation/nearest hit/etc programs…but when you realize it

Creating this “pipeline” for X-ray tracing software and assigning the device to it was relatively simple. In particular, you don’t even need to know what a “Shader Binding Table” is (let alone how to create it) or what data structures to create when, etc… OptiX 6 does it all. It is fully automatic.

The downside to this approach was that the OptiX 6 was too opaque: once you start becoming a power user, you can do things with the OptiX 6 that you didn’t want to do, or sometimes even wanted to do. t, etc… Since it was a closed source, you can’t even tell that easily

Sometimes he would do what he did, or what he should have done to avoid it. So it is very easy to get started, but sometimes confusing for professional users.

When the OptiX 7 came out, it shortened this issue by removing all “trap” functionality, all node graphics, etc., and instead exposing (newly added) RTX technology. Driver-level abstraction (in fact, it’s similar to DirectX/RT and VulkanRT abstraction levels). In this new “driver-level” abstraction, the user has complete control over everything, including which CUDA threads are used at what time, memory allocations that occur, CUDA memory types, and more. This change unlocks all. A new level of performance that users have used to great effect since then, and this has been the key to the rapid development over the past two years in high-performance GPU X-ray tracing. For a power user (well, at least for me!), switching from OptiX 6 to OptiX 7 was an amazing experience, plain and simple.

Understand the intricacies of accelerator structures, synthesize build inputs, and build/compress/rebuild accelerator structures; Compile programs and pipelines, create binding shader tables, and more. With the OptiX 7, there’s still more.

Easier than DXR or VKR, but still difficult for beginners…. And even for those who now fully understand all these low-level technical details, due to their low-level nature

Avoid getting shot in the foot by overlooking something or making copy-and-paste mistakes. This can easily take up time that could be spent more productively elsewhere.

OWL aims to help users overcome this gap between productivity and convenience on the one hand and low-level performance and control on the other: like OptiX 6, it provides a graphical node abstraction where the user can create and specify relatively high parameters to do with level objects such as “Buffers” and “Geometries”, “Groups” (i.e. Acceleration Structures) and “LaunchParams” with OWL then do all the simple tasks of managing device memory, creating/compressing/restore acceleration structures. , define initialization constants, handle multi-machine and asynchronous initialization, especially program creation, pipelines, and yes, mandatory shading table.

While OWL clearly aims to be convenient, it also takes a lot of the “give the user control” philosophy out of the OptiX 7: in particular, the OWL is a much “thinner” abstraction layer on top of the OptiX 7 compared to the OptiX 6: none. Magical Translator technology is ubiquitous in OWL and all device shaders are roughly the same as OptiX code without OWL (albeit with some convenience functionality). OWL is much “clearer” than the OptiX 6 because, for example

Who says that when SBT is created. Third, OWL is completely “transparent” in the sense that unlike OptiX 6, it is completely open source (, so the user can always see exactly what they are doing at any given moment? Over time… and even if he or she doesn’t touch any icon in the OWL itself, he can always see it

What OWL do at any time and what do you do to avoid obstacles or accidents. Finally, OWL is clearly intended to allow easy and efficient “selectivity” with CUDA, i.e. it’s possible to order in what kind of hardware address buffers or CUDA streams are used for initialization, etc… So, for example, it’s perfectly possible For a CUDA kernel that reads from or writes to some OWL data, or starts the same CUDA thread that OWL uses, a CUDA kernel asynchronously starts OWL, etc.

The web (or even the GitHub part of it) is full of libraries at different levels of sophistication, often abandoned or just doing what the project author needs and unfinished for anything else. And yes, I’m sure there are some bugs or missing features in OWL too that are not yet discovered because no one has used them yet in a certain way that might cause bugs or missing features. In particular, OWL is not
