Novel multi-volume rendering approach enables visualization of dozens of independent volume fragments with real-time performance suitable for VR surgical planning.
Depth buffer technique correctly handles occlusion and intersection of multiple volumes, overcoming limitations of single-volume and mesh-based rendering.
Close collaboration with experienced spine and neurosurgeons ensured clinical relevance for complex anatomical visualization, minimally invasive approach planning, and medical education.

Use direct volume rendering to retain original raw volumetric data for higher image quality and accuracy.
Segment volumes even roughly to enable high-quality visualization without loss of detail.

Employ depth buffer-based multi-volume rendering to allow interactive manipulation of multiple overlapping datasets in VR.
Utilize optimization techniques such as early ray termination, empty space skipping, and foveated rendering to maintain performance.

Engage experienced clinicians for qualitative assessment and iterative feedback during development and clinical use.
Monitor rendering performance to ensure acceptable frame rates and image quality to prevent VR-induced motion sickness.

Be aware of potential performance degradation when rendering multiple volumes simultaneously without optimization.
Avoid resampling entire scenes into single volumes to prevent loss of image quality and preclude real-time interaction.
