Notes & process.
A place for observations,
experiments and practical 3D notes.
Share a 3D product review link with clear access and retention rules
Define the audience and lifetime of a review link before uploading the product asset. A hard-to-guess URL is not equivalent to authenticated access, and a login on the review page does not protect an independently public model URL.
Animate glTF material properties with KHR_animation_pointer
Use KHR_animation_pointer only after checking the exact property and runtime path you need. The extension makes additional property animation possible, but it does not turn every material setting into a universally portable animation.
Handle unsupported glTF extensions with explicit fallbacks
Check the asset's extension requirements against the deployed rendering path before presenting it as a complete product. A valid file can depend on a feature the application does not implement. A loader warning is not an adequate customer-facing policy.
Build an interactive exploded product view with reversible part positions
Store the assembled transforms before moving any parts. Build the exploded state from that saved reference rather than adding offsets repeatedly to the current positions. This prevents accumulated drift when the user opens, closes, or interrupts the view.
Model size and module options without stretching product details
Do not scale the whole product when only one dimension is meant to change. Uniform or axis-specific scaling can stretch handles, holes, labels, and wall thickness along with the body. Define which regions vary and which retain their physical dimensions.
