Temple of Heaven Hall of Prayer for Good Harvest — TypeScript + Three.js WebGL Project

The original post showcases a 3D model and web experience of Beijing’s Temple of Heaven Hall of Prayer for Good Harvest, created with GPT-6 Astra and Three.js. The author later shared the complete Chinese prompt used to create this type of project.

Prompt optimization tips

1

Specify editability

State which objects must remain separate, named and editable; otherwise a visually convincing shell may still be unusable.

2

Close the test loop

Ask the model to run the scene, inspect visible failures and repeat until concrete frame-rate, interaction and layout checks pass.

3

Stage long builds

For large worlds, split the work into districts, assemblies or milestones and approve each section before expanding scope.

Imagine It. Shape It.
