generate_hyper3d_model_via_images

Create 3D models with built-in materials from images and import them into Blender for 3D asset generation.

Instructions

Generate 3D asset using Hyper3D by giving images of the wanted asset, and import the generated asset into Blender. The 3D asset has built-in materials. The generated model has a normalized size, so re-scaling after generation can be useful.

Parameters:

  • input_image_paths: The absolute paths of input images. Even if only one image is provided, wrap it into a list. Required if Hyper3D Rodin in MAIN_SITE mode.

  • input_image_urls: The URLs of input images. Even if only one image is provided, wrap it into a list. Required if Hyper3D Rodin in FAL_AI mode.

  • bbox_condition: Optional. If given, it has to be a list of ints of length 3. Controls the ratio between [Length, Width, Height] of the model.

Only one of {input_image_paths, input_image_urls} should be given at a time, depending on the Hyper3D Rodin's current mode. Returns a message indicating success or failure.

Implementation Reference

  • The implementation of the tool 'generate_hyper3d_model_via_images', which processes image paths/URLs and sends a command to the Blender connection to create a Rodin job.

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations provided, the description carries full burden. It successfully discloses that assets have 'built-in materials' and 'normalized size' (suggesting re-scaling may be needed), but fails to clarify if this is a blocking call or asynchronous (despite sibling 'poll_rodin_job_status' suggesting async), or potential error conditions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Well-structured with clear sections for behavior, parameters, constraints, and return value. The 'Parameters:' section is necessary given zero schema coverage. Minor redundancy between '3D asset' and 'generated model' references, but overall efficient.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 3 parameters with no schema coverage and no output schema, the description successfully covers parameter semantics, output characteristics (materials, size normalization), and success/failure indication. Only minor gaps remain regarding async behavior and explicit prerequisites.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description fully compensates by documenting all 3 parameters: it specifies absolute paths vs URLs, the list wrapping requirement even for single items, mode-specific requirements (MAIN_SITE vs FAL_AI), and the integer list format for bbox_condition with semantic meaning [Length, Width, Height].

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool 'Generate[s] 3D asset using Hyper3D by giving images' and distinguishes itself from sibling 'generate_hyper3d_model_via_text' by specifying the image-based input method. It also clarifies the secondary effect of importing into Blender.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Provides explicit constraint that 'Only one of {input_image_paths, input_image_urls} should be given' and explains the conditional requirements based on Hyper3D Rodin mode (MAIN_SITE vs FAL_AI). Lacks explicit comparison to when to use the text-based alternative versus this image-based one.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
