Hyper-Fidelity Voxel Simulation Spec - Giza Plateau (Old Kingdom Prime)
Updated Aug 13, 2026
OBJECTIVE
Construct a "Hyper-Fidelity" Voxel Simulation of the Giza Plateau at the height of the Old Kingdom.
The scene must be awe-inspiring, featuring the Pyramids in their original pristine state (polished white limestone with solid gold capstones), a lush, living Nile river delta, and the Great Sphinx.
VISUAL TARGET
This is not a "ruin" simulator. This is Ancient Egypt in its prime.
The resolution must be high enough to distinguish individual palm fronds and the architectural setbacks of the temples.
Daytime lighting must not feel flat or dull-maintain strong cinematic contrast (especially on the pyramids) and keep the Nile looking vibrant and "alive" across all times of day.
USER CONTROLS
Camera: Cinematic Orbit with smooth damping.
Lighting Control: On-screen buttons for Dawn / High Noon / Golden Hour / Starry Night + a Cycle button. (Keyboard shortcuts optional fallback, not required.)
Tour Mode: On-screen button to toggle an auto-flyover following the causeway from the Nile to the Great Pyramid.
Default lighting preset: Golden Hour.
WORLD GENERATION LAYOUT (West to East)
The Deep Desert (Background)
Topography: Rolling, undulating sand dunes (use noise functions for height). NOT a flat plane.
Color: Deep gold/orange sand.
The Plateau (Mid-Ground)
The Great Pyramids (3 Main, several Queens')
Geometry: Massive scale. Use a stepped-voxel algorithm but at a high density so the slopes appear smooth from a distance.
Placement: Ensure the main pyramids (and Queens' pyramids) are clearly separated with non-overlapping footprints and readable spacing.
Material: Polished White Limestone (Main body) + Solid Gold Pyramidions (The top capstone must shine/emit light).
The Great Sphinx
Must be positioned accurately guarding the causeway.
High-detail voxel modeling for the paws, nemes headdress, and face.
Painted details (traces of red/blue) if possible.
The River Valley (Foreground)
The Nile River: A wide, flowing body of water.
Water Effect: Voxel blocks must use a translucent blue/green palette with a shimmer animation and convincing specular/reflection so it doesn't look dull.
Vegetation Belt: EXTREMELY DENSE placement of Date Palms and Papyrus reeds along the banks.
The Harbor: Stone quays where boats (simple voxel barges) are docked.
ARCHITECTURAL DETAILS (The "Impressive" Factors)
Causeways: Long, covered stone corridors connecting the Valley Temples (at the river) to the Mortuary Temples (at the pyramid base).
Obelisks: Tall, needle-like spires placed at temple entrances, tipped with gold (electrum) to catch the light.
Civilization: Small clusters of mud-brick worker houses near the river to show scale.
ATMOSPHERE & LIGHTING
The "Ra" System: The sun must be the dominant force.
High Noon: Blinding white light, short shadows, the limestone pyramids should look almost glowing white (avoid a dull/flat look-use cinematic fill/reflection to keep form and sparkle).
Golden Hour: Long purple shadows, the sand turns deep orange, the gold tips sparkle (this should be the default).
Night: Dark blue sky, torchlight (orange point lights) flickering at the temples.
Reflections: If possible in the render budget, approximate the reflection of the Pyramids in the Nile.
TECHNICAL SPECIFICATIONS
Output: Full implementation.
Engine: Three.js (inlined via Import Map) or raw WebGL2.
Performance Strategy:
InstancedMesh is Mandatory: You must instance the "Sand Voxel," "Water Voxel," and "Palm Tree Voxel." Do not draw 100,000 individual meshes.
Matrix Transformation: Use matrix manipulation to scale the Pyramids without killing memory (one giant pyramid made of instanced blocks, or a single procedural mesh).
Occlusion: Do not render the inside of the pyramids.
Color Palette: Use a rich, saturated palette. Avoid "muddy" default colors.
Gold: Hex #FFD700 (High specular).
Limestone: Hex #F0F0E0 (High brightness).
Nile: Hex #2E8B57 (Deep green/blue).
IMPLEMENTATION GUARDRAILS
No External Assets: All textures/models must be code-generated.
Solid Geology: The sand dunes must mesh seamlessly with the river banks. No gaps in the world.
Planning: Ensure the Sphinx is not buried in a dune; flatten the terrain specifically where buildings are placed.
UI: Keep the on-screen HUD minimal and functional (no extra commentary text).
FINAL INSTRUCTION
Generate the full output.
Focus heavily on the contrast between the lush green riverbank and the stark, blinding white/gold perfection of the Pyramids.
