Homomorphic-Encrypted Volume Rendering [PDF]
IEEE Transactions on Visualization and Computer Graphics, 2020 Computationally demanding tasks are typically calculated in dedicated data centers, and real-time visualizations also follow this trend. Some rendering tasks, however, require the highest level of confidentiality so that no other party, besides the owner, can read or see the sensitive data.

Real-Time Volume-Rendering Image Denoising Based on Spatiotemporal Weighted Kernel Prediction [PDF]
Journal of ImagingVolumetric Path Tracing (VPT) based on Monte Carlo (MC) sampling often requires numerous samples for high-quality images, but real-time applications limit samples to maintain interaction rates, leading to significant noise.

Particle-based Volume Rendering
Transaction of the Visualization Society of Japan, 2007 本論文では，ボリュームデータを不透明な発光粒子の集合という離散モデルとして表現することによりアルファ合成およびソート計算を必要としない粒子ベースボリュームレンダリング法を提案する．本手法では，不透明属性を持つ発光粒子を，確率論的アプローチにより，利用者が与える伝達関数から推定される粒子密度分布に応じて発生する．そして，それらを画像面に投影することによってレンダリングを行う．さらに，本手法では，画像投影処理において粒子ごとの深さ情報の比較だけが必要とされるが，粒子半径を比較的大きく設定する，つまり各画素に1個程度の粒子が投影される場合には，ボリュームレンダリングの特徴である半透明表示が困難となる．このため，一つの画素に対して，複数の粒子が投影されるようにサブサンプリング処理を行い ...
