Graphics Programming weekly - Issue 196 - August 15, 2021

[pptx] Geometry Rendering Pipeline Architecture at Activision

  • the talk presents how Activision had to rethink the geometry pipeline when moving from tightly controlled levels to open worlds
  • focusing on the shipped F+ and experimental V+ implementation
  • shows what mesh types use what technique and explains the reasons
  • showing how the GPU based pipeline has been implemented around bitmasks and data expansion
  • presents performance numbers, final F+ culling pipeline reduces rendering time significantly
  • additionally contains a look at a possible tile-based V+ / F+ hybrid pipeline

[video] Anti-Racist Graphics Research (SIGGRAPH 2021)

  • the video discusses biases and assumptions that are baked into the graphics research
  • discussing the biases in terms such as skin, hair, flesh tones, human face
  • presents a look at history and how the same biases developed, and how it has been repeated
  • suggests future developments to address these biases going forward

Optimizing DX12 Resource Uploads to the GPU Using CPU-Visible VRAM

  • the article presents a new D3D12 Nvidia extension that enables a developer to allocate CPU-Visible VRAM memory directly
  • this allows developers to write directly into VRAM from the GPU
  • explains what tools are available to detect cases where it would be beneficial
  • additionally shows how to detect possible performance problems caused by reading from the CPU


Senior Render Programmer

Prague, Czech Republic, remote work considered

We are searching for a highly skilled and experienced Senior Render Programmer.

You could be developing state-of-the-art rendering solutions for our in-house game engine VRAGE, games such as Space Engineers or new, unannounced projects.

You’ll be working as part of the Rendering team, working closely with the Art and Design teams to help them achieve the artistic vision for our games.

SIGGRAPH 2021 Talk- Unbiased Emission and Scattering Importance Sampling for Heterogeneous Volumes

  • the paper presents a new distance sampling method
  • presents an extension for the null-collision integral formulation that improves efficiency for low-order heterogeneous (such as fog)
  • additionally presents an approach using a spatial guiding data structure

2D Lighting with Hard Shadows

  • the article presents a polygon extension-based method for the generation of 2D shadows
  • explains the necessary math and how to generate the required mesh data
  • also discusses problems, performance implications, and optimization techniques
  • additionally presents two alternative techniques

2D Lighting with Soft Shadows

  • the blog post extends the previously discussed hard shadow method to support penumbra based soft shadows
  • presents how to generate the mesh data to include the penumbra and be able to derive the falloff from linear operations
  • presents the shader implementation using GLSL

Introducing a New API for Checking Feature Support in Direct3D 12

  • the blog post presents a new helper class (CD3DX12FeatureSupport) that unifies the D3D12 feature checking into a single class
  • part of d3dx12
  • aims to unify the patterns and behavior across the different existing methods in stock d3d12

Introduction to Caching Shading Information in World Space using Implicit Progressive Low Discrepancy Point Sets

  • the article presents an overview of a master thesis about caching shading information in world space
  • technique is based on implicit point generation and accumulation into global hash tables
  • the presented example shows the technique applied for ambient occlusion

Pilotier is a startup tackling one of the toughest outstanding engineering challenges: autonomous urban driving. We are taking a camera-first approach and are designing for hardware that is two to three years out. If you like big challenges and working with smart people, join us on our quest.

Your job will be to collaborate with simulation and deep learning engineers and help us build a ground-breaking product from scratch.

You have an eclectic background. You’ve delved deep into the graphics pipeline. You’ve worked with game engines. Maybe you’ve built your own. You’ve written many lines of C++ (even though maybe you secretly can’t stand it). You like solving hard problems, startups, and working with smart people. Nothing scares you. Vulkan? Hah! Maybe you’ve dabbled with functional programming languages, like Erlang or Elixir. Perhaps even Haskell. You’re independent and self-motivated. You love learning new things. Nothing is impossible, some things just take a bit longer to figure out. It’s just code.

We are based in Montreal but are all remote, so your physical location is not an issue.
