VOL3D使用正交平面的2-D纹理体积渲染的3-D在OpenGL中的数据映射技术。使用“纹理”选项进行微调的纹理映射技术。此功能最适合用于快速的OpenGL硬件。-VOL3D uses the orthogonal plane 2-D texture mapping technique for volume rending 3-D data in OpenGL. Use the　texture　option to fine tune the texture mapping technique. This function is best used with fast OpenGL hardware.
