Clouds based on 4d noise. Tiles properly if scale is 1.

Fork of Perlin Clouds

Projective texturing

Logarithmic Depth buffer with custom near/far planes

Electrobunny

An animated image based noise pattern. Inspired by https://www.shadertoy.com/view/ldlXRS

Fork of Noise Ripples

Triplanar with anti-tiling texturing

RM Test

New tiled lava Surface Shader

Terrain types height-based mix

Shameless adaptation of http://glslsandbox.com/e#57871.0

Rave bunny

Bad creep attempt

Procedural surface bumps (cellular noise);
Procedural surface bump normals;
Procedural TBN matrix calculation (Including Gram-Schmidt re-orthogonalization process)
Normals perturbation;
Parallax mapping (simple and occlusion) from
      https://learnopengl.com/Advanced-Lighting/Parallax-Mapping

Bugs:
NORM_METHOD == 1 looks bugged. Why?
Shows "Shader Error!", although it's loop unroll warning
Teapot handle has wrong model normals (see incorrect shading)?

Procedural Bump with Normal mapping

Sine Noise 3D

Electro Orb

Adaptation of http://glslsandbox.com/e#44589.1

Magic orb

Strange Surface

Strange surface

Tell me if you know the way to make it without fugly seam on the back.

Lightning orb

ZK shield

Linear depth [0;1]

Fork of Electric Wave

Noise animation - Watery

Soul Sphere

Clean version of https://shaderfrog.com/app/view/2360

Sphere covered with hexagon grid (mostly)

Took me a year(?) to create hexagon covered sphere in the frag shader.

Proper hexasphere (without cut edge artifacts finally!!!)
