- the video tutorial introduces swizzle operations
- shows how to emulate functionality in Unity that is available natively in UE
- the article presents the shader multiply/add operation (fma/mad)
- discusses how it’s mapped onto the hardware and allows more efficient and precise operations
- shows example use cases, discussing the impact on the precision of the calculation results
- the tutorial describes the capturing process for image-based lighting
- IBL probes are omnidirectional representations of lighting information captured from high dynamic range images of a location
- shows how to capture the images and set up the pipeline to integrate the captures into the renderer
- explains how all captured with different exposures are combined into a single IBL probe
- the article describes the hardware characteristics of the PS1 renderer
- shows a visual demonstration of the effect of sub-pixel rasterization and perspective correct interpolation
- additionally shows how to emulate the hardware shortcomings to create a PS1 style look on today’s hardware
- the paper introduces a combination of tile-based stochastic light culling and reservoir sampling
- this reduces the variance for lights close to surfaces such as common in Virtual Point Lights (VPLs) based indirect illumination systems
- the article shows how gradients differ with different color spaces
- compares sRGB, linear, and Oklab color spaces
- the article presents the Vulkan SDK layer architectures
- introduces how to enable Arm performance warning layer
- additionally shows how to run the layer on RenderDoc captures to gather information
- the article provides an overview of use cases for ray tracing
- discussing disk and memory space-saving, shadows, reflection
- also mentions the effects on user-generated content
- the article discusses the importance of asserts for debugging a renderer
- shows how asserts are implemented in PBRT
- additionally presents an example from the PBRT development where asserts helped to catch a performance issue
- the article explains what information GPUView and Radeon GPU Profiler show
- shows how items are progressing through the queue over time
- additionally shows how to see how utilized the GPU is over time
- the article provides an overview of the bloom technique and implementations
- comparing the technique implemented by UE and Call of Duty and how the suggested solution is a combination
- shows how to integrate a custom implementation into the UE4 codebase
- the video tutorial provides an overview of the skinning animation technique
- explaining the process of how data is authored, animated, and encoded in a GPU friendly format
- additionally shows how to set up, compile and use Assimp to parse the initial skinning poses
