Rethinking Texture Mapping course notes
this course we will discuss various radically different ways to rethink texture mapping that have been proposed over decades, each offering different advantages and trade-offs
Ubershaders: A Ridiculous Solution to an Impossible Problem - dolphin-emu.org
Dolphin will use the already compiled Ubershaders to immediately render the effect without stuttering while still compiling the specialized shader in the background
Optimal grid rendering is not optimal - zeuxcg.org
interesting exercise of measuring the actual behavior of given index sequences on real hardware, and trying to model several possible approaches hardware could take to understand the behavior better
A Tour of sokol_gfx.h - floooh.github.io
takes ideas from Metal and D3D11, plus a few ideas from D3D12/Vulkan, and wraps them into a simple C API
Production Volume Rendering SIGGRAPH 2017 Course
This course picks up where the last ones left off, explaining not only the basic theory underpinning these recent advances, but also presenting a detailed and concrete look at their implementations.
Mesh color textures convert the mesh color data to a format that can be efficiently used by the texture filtering hardware on current GPUs. Utilizing a novel 4D texture coordinate formulation, mesh color textures can provide correct filtering for all mipmap levels and eliminate artifacts due to seams.
- Allows a SPIR-V usage instead of GLSL
- KHR_parallel_shader_compile extension is about allowing multiple shader compile threads
- and many more things
This subgroup is tasked with developing specifications, open-source library code and tools, together with conformance tests to define and support the set of Vulkan capabilities that can be made universally available across all major platforms, including those not currently served by Vulkan
