  3. Particle tracing

  4. Contour plotting
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Volume rendering is a technique used to visualize 3D data by assigning colors and transparencies to voxels (3D pixels) based on their properties. This allows astronomers to visualize the internal structure and distribution of objects in space.

Multiple choice

Which of the following is a common technique used for hair simulation?
