Tellusim SDK 48 is here! Indirect TLAS builds, GraphFlow node-based compute shaders, FSR & FXAA plugins, and tons more: tellusim.com/sdk-48/

A new tutorial describes how to use Ray Tracing with #Tellusim Core SDK. It's not any more difficult than rasterization. The tutorial includes a comparison between Ray Tracing and CS rasterization: tellusim.com/05_hello_traci…

@bkaradzic Exactly! And it is still in use for CPU and GPU radix sort algorithms: #L205" target="_blank" rel="nofollow noopener">github.com/Tellusim/Tellu…

@frustum It seems like old "trick" used to help with sorting floating point values with radix sort. stereopsis.com/radix.html

Not all graphics APIs support atomic min/max operations on floating-point numbers. This trick allows it using standard integer min/max atomic operations, with negligible performance impact:

@rompa69 @guycalledfrank Yes, it is possible to use bitwise logic: pack: u ^ (((u >> 31u) * ~0u) | 0x80000000u) unpack: u ^ (~((u >> 31u) * ~0u) | 0x80000000u)

@frustum @guycalledfrank Can you not instead mix using (u >> 31) ?

GPU-driven ray tracing with double precision opens incredible possibilities with #Tellusim Engine. youtu.be/sKcFqcjXSug

The performance of multi-viewport rendering is not different from the single-viewport mode in #Tellusim Engine. It allows using an enormous number of screens/HMDs to a single PC, rendering the same scene using multiple GPUs. A single 2080Ti can easily run 5 2k screens with Google Map Tiles API data.

#Tellusim Explorer can easily handle the editing of 500,000 #GravityMark asteroids. Each asteroid has the correct motion vectors even when animated using a compute shader.

MuJoCo physics plugin in Tellusim Engine:

Loading USD files with NodeGraphNodeAPI (MaterialX) materials is now just a single line of code! Thanks to the improved USD loader and updated MaterialX plugin, this demo showcases NVIDIA Omniverse PhysicalAI SimReady materials running inside Tellusim Engine.

Tellusim MaterialX plugin has been updated and now includes OpenPBR materials support.

A new 3D Interface plugin demonstrates how to embed CPU-based objects into the GPU-driven rendering pipeline. #Tellusim provides a customizable injection API for all rendering steps, and a compute shader API allows the querying of any scenegraph parameters.

A new manual for the Tellusim User Interface system is here: tellusim.com/09_hello_contr…

New Tellusim Core SDK samples showcase oneAPI and Level Zero interop with Vulkan and D3D12: github.com/Tellusim/Tellu… github.com/Tellusim/Tellu… github.com/Tellusim/Tellu… github.com/Tellusim/Tellu…

Real-time relighting of 7M splats scene on Max Studio M1 Max:

#Tellusim's GPU-based Node scattering is not limited by geometry. It involves Lights, Decals, or Node hierarchies and delivers astonishing results with GPU-driven rendering and multi-GPU support. Two 2080Ti GPUs can renders this scene on 4 2K displays at 60 FPS and scales without limits.

It's impossible to list all the features of the new #Tellusim SDK 31. You can find all the details on our forum. The globally scattered Earth demo is the best showcase of this release:

A list of predefined macro values has been added to the Shader guide: #predefined-macro-values" target="_blank" rel="nofollow noopener">docs.tellusim.com/core/started/0…

Tellusim SDK 44 is here! It brings support for Apple tvOS platform, MuJoCo physics plugin, an Inverse Kinematics plugin, improved compatibility, real-time state tracking, and major tool and API upgrades. Details: tellusim.com/sdk-44/

Tellusim Engine now supports unlimited morph targets! Check out the latest demo featuring this capability alongside Tellusim ARLink:

Tellusim SDK 46 is now available. Highlights: bloom post-processing, improved temporal AA & upscaling, updated XeSS & DLSS plugins, new Explorer prefabs, multi-language templates (C#, Rust, Swift, Java, JavaScript, Python), and more: tellusim.com/sdk-46/
