Water Rendering using the Projected Grid Method with Perlin Noise
Water Rendering using the Projected Grid Method with Perlin Noise
Note
Requires a graphics card with the deprecated GLSL version ~1.20 to properly run.
Comments
The projected grid method is used to determine a quadrilateral-boundary of the water plane within the view frustum. Waves are displayed by perturbing the vertices on the surface of the water according to the 2D Perlin Noise texture, which is generated by code. The surface is animated by linear interpolation between 2 2D Perlin Noise textures.
Of note, the rendering includes light refraction and reflection.
