IsleLight

Islelight (pronounced eye-light)

This program is a submission to Acerola's "Dirt Jam". This program requires some modern gpu features such as VK_FORMAT_R32G32B32A32_SFLOAT - older or integrated GPUs may not support this.

The program uses a few interesting techniques:

• generates a heightmap using fbm / perlin noise in a glsl shader
• reads the result back to the cpu, which is used for physics mesh generation
• distance fog
• shiny water
•  cascading shadow maps for large scale shadows
•  objects/foliage scattered across terrain at runtime based on some basic rules
• several terrain textures that vary by height, slope

This was made by Matt Hughes in July 2025.

Controls:

• Space to start
• Right-click to zoom
• Esc to pause
• G toggles gravity
• N cycles lighting presets
• WASD/Space to move
