Internal Structure of Kidney 

The main goal of this project was to illustrate a structurally accurate anatomical subject with a cutaway to reveal an aspect of its internal structure. The subject must look alive with real-world lighting cues that suggest its form, volume, and texture. 

 

I want to showcase the different cross-sections of the kidney, as well as the cross-sections of renal pyramids and ureter.

Preliminary Studies

I wanted to show more dimensions of the kidney by including a traditional coronal cut, a sagittal cut, and also a transverse cut. I bought some pork kidneys to help me visualize the cuts. I also utilized 3D models to help me understand the anatomy of the kidney.

Texture References

To render the textures of different structures in the kidney, I found image references of pork and goat kidneys since they have similar textures and colors to human kidneys. I also watched surgical videos for rendering adipose tissues.

Rendering 

A grayscale draft was created by first blocking each structure a flat color. Lighting information was added afterwards guided by 3D model. Textures were created with a variety of brushes to contrast the smooth, shiny ureter and the striated renal textures. 

Using Procreate, I added the colours using layers set to multiply, colour doge and screen mode.
