I am currently working on improving the custom Vulkan renderer that powers PeakVisor’s Android app.

Mesh shaders represent a notable evolution in modern graphics pipelines.

This is the paper page of our paper “Fast Rendering of Parametric Objects on Modern GPUs”, which has been accepted for The Eurographics Symposium on Parallel Graphics and Visualization (EGPGV) .

This is the paper page of our paper “Vulkan all the way”, which is an extended edition of our previous paper The Road to Vulkan: Teaching Modern Low-Level APIs in Introductory Graphics Courses and has been accepted for publication in the Computers and Gra…

When using floating point variables, there’s always the danger that a certain number cannot be represented exactly.

This is the paper page of our paper “The Road to Vulkan: Teaching Modern Low-Level APIs in Introductory Graphics Courses” which has been accepted and presented at Eurographics 2022 in Reims, France.

This is the paper page of our paper “Conservative Meshlet Bounds for Robust Culling of Skinned Meshes” which has been accepted and presented at Pacific Graphics 2021.

I currently have access to PCs which are of totally different form factors—one being a desktop-PC, the other being a laptop-PC—and actually have pretty different CPUs—the former featuring a (then-high end) AMD Ryzen AMD Ryzen 9 3900X with 12 physical core…

In this post, I’d like to describe a strategy how a proper and (hopefully) easy to understand perspective projection matrix for Vulkan can be set-up manually.

When programmers with an OpenGL background learn Vulkan, they often expect—or hope—that the projection matrices they have used with OpenGL continue to work with Vulkan.
