GPU FlowField Pathfinding

    This is take two on global distance field Pathfinding. I could improve the previous version a lot in terms of performance and quality. The technique changed…

Space Syntax – Isovists

  This is a quick extension to the previous post. The isovists are computed in realtime by sampling a huge mount of directions in parallel at each location…

Space Syntax – Realtime Local Features (Isovist, Axis, Radials, …)

  A while ago I experimented with 3D SpaceSyntax and efficient computation of 3D isovists and other local properties like signed distance volume voxels, etc… . It was…

3D Global Line Radiosity – Test Scenes

Two testscenes for showing the pros and cons of this technique. The application computes Global Illumination, using Global Line Radiosity Realtime Global Line Radiosity Scenes The outdoorscene (enabled…

Realtime 2D Radiosity – Comparing to 3D, Part 3

This post shows a quick comparison of my latest 2D radiosity renderer and my original 3D renderer. Both implementations are GLSL implementations of Global Line Radiosity (more or…

Realtime 2D Radiosity – Global Illumination for 2D Scenes

This post is about a new algorithm I have been working on to compute Global Illumination in realtime for 2D scenes. The Algorithm is based on the idea…
