Parameters

loadRate

Type: SystemInt32

You can set this parameter separately for each data set using field SoLDMResourceParameter.tex3LoadRate. Default is 10 3D textures (effectively 3 tiles) per render traversal.

Each tile needed for volume rendering (OIV.VolumeViz.Nodes.SoVolumeRender) and volume geometry must be transfered to GPU memory as a 3D texture. So, for example, transfering 1000 tiles at the default loadRate (10) requires 100 frames. (How many seconds this takes depends on the frames per second possible, which in turn depends on many factors including the complexity of the scene graph.) Increasing the loadRate value reduces the number of frames required to reach maximum resolution. But the render traversal has to wait for the data transfer to finish, so each frame may take longer to render, increasing the total time to reach maximum resolution.
