description	Creates procedural and organic shapes in Minecraft using VibeCraft MCP tools. Use when building spheres, domes, cylinders, pyramids, torus, arches, curves, spirals, organic shapes, statues, or any complex geometry that requires procedural generation.

Creating Shapes

MCP Tools

• worldedit_generation - sphere, cylinder, pyramid, cone
• build(code=...) - Python code that generates commands (RECOMMENDED)
• worldedit_deform - Math expressions

build() Code Mode (RECOMMENDED)

Sphere

build(code="""
commands = []
cx, cy, cz, radius = 105, 70, 205, 10
for x in range(cx - radius, cx + radius + 1):
    for y in range(cy - radius, cy + radius + 1):
        for z in range(cz - radius, cz + radius + 1):
            if ((x-cx)**2 + (y-cy)**2 + (z-cz)**2)**0.5 <= radius:
                commands.append(f'/setblock {x} {y} {z} stone')
""", description="Solid sphere")

Hollow Sphere

# Add: if radius - thickness <= dist <= radius:

Dome (Half Sphere)

# Limit y range: for y in range(base_y, base_y + radius + 1):
# Use: dist = ((x-cx)**2 + (y-base_y)**2 + (z-cz)**2)**0.5

Cylinder

build(code="""
commands = []
cx, cz, base_y, radius, height = 105, 205, 64, 8, 20
for y in range(base_y, base_y + height):
    for x in range(cx - radius, cx + radius + 1):
        for z in range(cz - radius, cz + radius + 1):
            if ((x-cx)**2 + (z-cz)**2)**0.5 <= radius:
                commands.append(f'/setblock {x} {y} {z} stone_bricks')
""", description="Solid cylinder")
# Hollow: if radius - thickness <= dist <= radius:

Cone

# Per layer: radius = base_radius * (1 - (y - base_y) / height)

Pyramid

build(code="""
commands = []
cx, cz, base_y, half = 105, 205, 64, 10
for layer in range(half + 1):
    size = half - layer
    for x in range(cx - size, cx + size + 1):
        for z in range(cz - size, cz + size + 1):
            commands.append(f'/setblock {x} {base_y + layer} {z} sandstone')
""", description="Pyramid")

Torus (Donut)

build(code="""
commands = []
cx, cy, cz, major_r, minor_r = 105, 70, 205, 12, 4
for x in range(cx - major_r - minor_r, cx + major_r + minor_r + 1):
    for y in range(cy - minor_r, cy + minor_r + 1):
        for z in range(cz - major_r - minor_r, cz + major_r + minor_r + 1):
            dist_xz = ((x-cx)**2 + (z-cz)**2)**0.5
            tube_dist = ((dist_xz - major_r)**2 + (y-cy)**2)**0.5
            if tube_dist <= minor_r:
                commands.append(f'/setblock {x} {y} {z} gold_block')
""", description="Torus")

Spiral Staircase

# Use: angle = step * (2 * pi / steps_per_rotation)
# x = cx + cos(angle) * radius, z = cz + sin(angle) * radius
# Facing based on angle quadrant

Arched Bridge

# Use: arc = sin(progress * pi) * arc_height where progress = (x - start) / length

WorldEdit Shapes

/sphere stone 10       # Solid sphere r=10
/hsphere glass 10      # Hollow sphere
/cyl stone 5 10        # Cylinder r=5 h=10
/hcyl glass 5 10       # Hollow cylinder

Expression Shapes

/generate gold_block (sqrt(x*x+z*z)-12)^2+y*y<16  # Torus
/generate stone (x*x)/100+(y*y)/25+(z*z)/100<1    # Ellipsoid
/generate stone y<sin(x/5)*3+64                    # Sine wave

Code Sandbox Limits

Allowed: for loops, list comprehensions, math ops, math module NOT Allowed: while, def, lambda, imports (except math), try/except Limits: 10,000 commands max, 100,000 iterations max

Distance Functions

# Euclidean (spheres): ((x-cx)**2 + (y-cy)**2 + (z-cz)**2)**0.5
# 2D (cylinders): ((x-cx)**2 + (z-cz)**2)**0.5
# Manhattan (diamonds): abs(x-cx) + abs(y-cy) + abs(z-cz)
# Chebyshev (cubes): max(abs(x-cx), abs(y-cy), abs(z-cz))

Shape Formulas

Shape	Formula
Sphere	x² + y² + z² ≤ r²
Ellipsoid	(x/a)² + (y/b)² + (z/c)² ≤ 1
Cylinder	x² + z² ≤ r²
Cone	x² + z² ≤ (r(1-y/h))²
Torus	(√(x²+z²) - R)² + y² ≤ r²

Tips

1. Hollow > Solid (fewer blocks)
2. Preview first: build(preview_only=True)
3. Use /fill for rectangular parts
