- a collection of papers from the I3D 2023 presentation
- contains links to the papers and related material where available
- the GDC talk explains how Quaternions and Dual Quaternions work and how they affect objects under transformation
- starts by building an understanding of Quaternions, shows the advantages and limitations
- followed by an extension to cover Dual Quaternions, explaining what problems they solve and how they compare to 4x4 transformation matrices
- the GDC presentation discusses the new sky rendering model developed for GT7
- presents the physical foundations and how to simulate them in an offline rendering system
- followed by how the sky method has been adjusted to be used in real-time through heavy use of LUT
- discusses how to control the method through simplified parameters
- additionally covers how they approached cloud rendering
- the short tutorial presents how the FXAA algorithm is implemented
- presents how the algorithm works in simple terms
- the article discusses techniques to calculate Bézier that use fewer segments than the existing original path
- presents the importance of an error metric and discusses different available options
- the latest version released from the Open MaterialX standards adds support for MaterialX Graph Editor and support for Metal shader generation
- also adds support for coated emissive surfaces and bitangent input vectors
- the article presents several different methods to convert between 32 and 16-bit floating point formats
- discusses the implementation, issues, and considerations with each technique
- the tutorial explains how to use WebGPU to use compute shaders to calculate the MIP maps for textures
- presents the implementation of a one MIP level at a time technique
- the article presents how to introduce custom shader nodes into the Godot Visual shader graph
- shows an example of how to color an object following the UVs
- the article introduces two new interactive playgrounds for integer and floating point numbers
- allows experimenting with how different numbers are encoded into the underlying bit patterns
