About

The first time when I saw an arcade machine was when I was around 12 years old. I think it was Scramble and I was completely awe-struck by the graphics and sound.- Even the smell was something out of this world!From that moment I knew I had to learn how to program these "dream machines".As this was in a time before the internet I had some challenging times ahead of me.I persevered with a clear view on my goal - by the time I was 20 I had moved to England to work as a games programmer.It truly was my first dream come true!As a person I am dedicated and pragmatic with clear goals - I have the energy and mindset to get there.One of my strengths is the ability to see patterns and make solutions based on characteristics, formats and arrangement.Not only in details - such as the layout of low level 3D data - also in architectural and design overview.How parts connect to and affect each-other.Since 2020 I have been specializing in physically based rendering (PBR) - absorbing knowledge about Fresnell equations, BRDFs, plausible light calculations using material properties and glTF.During this time I have participated in the glTF standardization - proposing several format extensions to the Khronos group - released a Vulcan based PBR (Fresnell) opensource renderer using advanced GPU features, such as instanced rendering - all while focusing on how to accelerate realistic rendering using the immense parallel computing power of GPUs. I challenge the status quo and question monolithic thinking - a forward thinking innovator.As an apprentice in life I constantly strive to be curious, learn and improve!Link to Vulkan Fresnel based opensource instanced renderer: https://github.com/rsahlin/varg-engine

Slagthuset, Jörgen Kocksgatan 7A, 211 20 Malmö

Held a 45 minute talk called 'High Performance Old School Sprites in OpenGL(ES) Using Batching: Increasing Your Performance to Eleven!" In this talk I explained how to use a batching technique to draw a very large number (>2000) of sprites on a low end mobile device using OpenGLES 2.X. Details also include how to manage attribute data and how to calculate screen position to avoid texture bleeding in the texture atlas. Covering the basics of performance profiling. http://www.nordicgame.com/
