3D Game Shaders For Beginners

• shader tutorial aimed at beginners that teaches shader fundamentals using Panda3D and GLSL
• starting with the basics of coordinate spaces, and GLSL shaders
• shows how to implementing texturing, lighting, normal mapping
• additionally outlining, fog, bloom, screen space ambient occlusion, depth of field and several stylization techniques

Using AMD Freesync 2 HDR: Tone Mapping

• explains tone mapping terms and how the human vision perceives changes in luminance
• the viewing environment has a significant influence on the perceived dynamic range
• shows how different display technologies deal with bright pixels and what artifacts they produce
• FreeSync provides information about the HDR capabilities of a connected to monitor to the application to be able to adjust the tone mapper accordingly

blockwise multi-order feature regression for real-time path tracing reconstruction

• paper on path trace denoising
• aimed at interactive scenarios with 1 sample per pixel
• using linear regression and temporal anti-aliasing combined with many problem-domain specific improvements

Vertex Data and Vertex Descriptors

• Vertex Descriptors in Metal allow the programmer to describe the memory layout of vertices
• shader compiler inserts the necessary fetch logic to read the data correctly
• this allows decoupling of vertex memory layout from the usage in shaders

Portals with Asymmetric Projection

• shows how to implement Asymmetric Projection
• adjust the projection on a render-to-texture in 3D space so that it appears as if the viewer is looking through a portal into another 3D space

Radeon GPU Profiler 1.5.1

• the new version adds support for hardware-level tracing on an instruction level
• now shows the ISA inside of the pipeline view too
• support for user markers have been added
• a small overview of how to interpret the provided data

[video] Real Time Continuous Lever of Detail Rendering of Point Clouds

• video for article discussed in issue 76

Using the bgfx library with C++ on Ubuntu

• the tutorial shows how to use BGFX running on Linux
• initialize BGFX, load shaders, and models and draw a cube on screen

Unity 2019 Shader Development

• example project for a course teaching the basics of shader development using Unity
• covers vertex, pixel, surface shaders
• additionally talks about Shader Graphs and post-processing

Technically Art: Issue 18 (17.05.2019)

• collection of VFX tweets of the week
• tutorials, demos, and showcases of great looking effects

Seeing the whole Physically-Based picture

• presents what kind of approximations are still required to be done in Physically Based Rendering
• opens the question that we should start looking at the approximations to determine where to focus on for the next generation of visuals
  

Proposal for WebGPU as a new Standard Cross-Platform Graphics API (OpenGL replacement)

• proposal of requirements that would allow WebGPU to be used as a common cross-platform abstraction
