1. Heart is animated using morph targets set up appropriately in the respective 3D applications. 2. A transparent human model is included to give a sense of the organ's location, without cluttering the important details inside. 3. Optimized subdivision cage gives smooth edges even in high definition. Just step up the subdivision levels.* 4. Heart is textured and bump mapped with 2048 x 2048 image. Materials are applied to all objects. 5. Clean topology. Only tris & quads used. 6. Modeled to real world scale.
*The original model is smoothened using TurboSmooth in Max, SmoothMesh in Maya, Subpatch in XSI & Lightwave, and Subdivision in C4D & Blender, which renders exactly like the preview images, and yet preserving the original low mesh density like the wireframe preview.
The user only need to crank up the subdivision to get a high poly & detailed mesh for rendering, OR crank down the subdivision for a low poly mesh while animating. ==========================================
