“…Brain tractograms are represented using 3D polylines. Such data are commonly used in real-time computer graphics to model hairs or fur [WBK*07;JCLR19]. Fur typically contains a few hundred thousand strands with 3 to 4 vertices [JCLR19] while tractograms can contain several millions of fibers with up to a thousand vertices per fiber leading to billions of segments.…”

Fabric rendering with fiber-level details uses detailed fibers [ZLB16; WY17] but relies on procedural generation directly on the GPU as well as on Level of Details (LoDs).…”

Real-time rendering (40ms/frame) of a 64GB brain tractogram containing 3 million of individual fibers (5.37 billion segments) compressed down to 7GB. From left to right, the figure shows the rendering using different shadings (solid color, fiber orientation, per-fiber color), the ability for our pipeline to perform interactions with occlusion meshes (here with a cube mesh), and the per-fiber interaction capabilities with a selection (combined here with an occlusion mesh).

Hair rendering has been a focal point of attention in computer graphics for the last couple of decades. However, there have been few contributions to the modeling and rendering of the natural hair aging phenomenon. We present a new technique that simulates the process of hair graying and hair thinning on digital models due to aging. Given a 3D human head model with hair, we first compute a segmentation of the head using K-means since hair aging occurs at different rates in distinct head parts. Hair graying is simulated according to recent biological knowledge on aging factors for hairs, and hair thinning decreases hair diameters linearly with time. Our system is biologically inspired, supports facial hair, both genders and many ethnicities, and is compatible with different lengths of hair strands. Our real-time results resemble real-life hair aging, accomplished by simulating the stochastic nature of the process and the gradual decrease of melanin.
