About

Hey! I'm Mateusz, a graphics programmer currently working at Techland, with previous experience at Crytek. My passion lies in graphics programming, particularly focusing on shaders and low-level implementation. I enjoy diving deep into rendering techniques and optimizing visual fidelity while maintaining performance.

When I'm not working on professional projects, I dedicate my free time to developing my personal graphics engine, exploring cutting-edge rendering techniques and implementing features I find fascinating.

RT GI and Volumetrics

Real Time GI

• Both diffuse and specular component
• Based on ReSTIR GI
• Variable Rate Tracing
• DDGI used as light cache and for volumetrics
• Fully integrated with clouds and atmosphere
• Doesn’t require baking

Volumetric Clouds

• Procedural shapes based on The Real-time Volumetric Cloudscapes of Horizon: Zero Dawn
• Multiscattering based on (based on Oz: the great and volumetric)
• Affect and are affected by aerial perspective
• Directional Light Shadows
• Affect DDGI via set of localized cloudscape probes (similar to RDR2)
• Visible in reflections via probe rendered from camera perspective

Volumetric Fog

• Algorithm based on frustum aligned voxels
• Covers both close and far distances (up to 8 kilometers)
• Based on:

Other Features

• Ray Traced Ambient Occlusion
