DESCRIPTION

The Human Circulatory System Model is an intricate 3D representation of the heart, blood vessels, and blood flow mechanisms that transport oxygen, nutrients, and waste products throughout the human body. This model showcases essential components such as the heart, arteries, veins, capillaries, and the blood flow through the pulmonary and systemic circulations. It illustrates how oxygenated blood is pumped from the heart to the body's tissues and organs, while deoxygenated blood returns to the heart. This highly detailed model is perfect for educational, medical, and anatomical studies, offering a comprehensive and realistic view of human circulatory dynamics.

This model supports FBX, OBJ, STL, GLB, USDZ, and BLEND formats, ensuring compatibility with various 3D applications and platforms.

No unsupported objects
Unsupported objects:
- Lights
- Cameras

Geometry
No N-gons
N-gons are polygons with five or more sides which might cause issues in certain processes like rendering or animation. Learn more
No faceted geometry
Faceted geometry uses flat surfaces without smoothing, which can look unrealistic on curves.
Learn more
Manifold geometry
Manifold geometry ensures all surfaces are properly connected, avoiding issues like edges shared by more than two faces.

Textures & material
PBR textures
PBR textures simulate how light interacts with materials, making the model look realistic under different lighting.
Required PBR textures:
- Base Color
- Roughness
- Metalness
- Normal
Learn more
No embed textures
Embedded textures are stored inside the model file, increasing its size and sometimes causing compatibility issues.
Learn more
Square textures
Texture aspect ratio is the width-to-height ratio of a texture. Expected texture aspect ratio: 1:1
Learn more
Power of 2 texture sizes
Textures with dimensions in power of two (e.g. 512x512px, 1024x1024px) are used to optimize performance and memory usage.
Learn more
Assigned materials
Materials are applied to the 3D model to allow visualize a model's surface properties and appearance.
Learn more
UVs & naming
No UV overlaps
UVs overlap when multiple points on the 3D model's surface are mapped to the same point on the UV island causing texture stretching.
Learn more
UV unwrapped model
A UV unwrapped model means its 3D surface is flattened into 2D space, allowing textures to be applied accurately.

Provided by designer
Information and details shared directly by the model's designer.
3D Features
Animated
The model includes animations (movement or actions) that can be played in supported software or engines.
Rigged
The model has a skeleton or bone structure, making it ready for posing or animation.
Low-poly
PBR
Uses Physically Based Rendering materials, which give the model realistic lighting and surface properties.
Textures
The model includes image files (textures) that add color, patterns, or detail to its surfaces.
Materials
The model has material settings that define how surfaces look (color, shine, transparency, etc.).
UV Mapping
The model's surfaces are mapped to a 2D image, allowing textures to display correctly.
Plugins Used
Some external plugins were used to create the model. These may be required for full functionality.
3D printing
