GLSL Raycasting
Raycasting inside a GLSL fragment shader
Here I test out the feasibility of performing raycasting inside a fragment shader, with moderately complex models (3D fractals).

Cathedral
Alternative fractal parameters
Cathedral (blurry fog)
Fewer raycasting steps for fog effect
Cathedral (faster motion)
Moving more quickly through the scene
Cathedral (higher detail)
More raycasting steps for a sharper image
First Fractal
First test of fractal casting in a shader
