Detailed Description
The VolumeViewer module implements a volume renderer for SCIRun using 3D texture hardware.
The Basic frame allows the selection of standard (Over Operator) or maximum intensity projection (MIP) rendering styles. It also allows for selection of 16 or 32 bit blending modes. There is also a selection for Trilinear or Nearest interpolation and a slider for changing the opacity of the volume. Software ColorMap2 Rasterization can be forced on in the unusual event that the default rendering mode does not work.
The Sampling frame allows the user to change the sampling rate for interactive and non-interactive use. The number is a multiplier and the formula used to compute the actual number of slices is "rate * sqrt(nx * nx + ny * ny + nz * nz) / sqrt(3.0)", or approximately Sampling Rate slices per texture element. Adaptive sampling refers to the rate at which the volume is sampled while the viewer is being interacted with.
The Shading frame is used to control the lighting properties of the volume visualization. The Shading button toggles lighting of the volume's drawn elements and the material is used to modulate the lighting color. This option requires that the texture be built with normals. It also requires a graphics card with fragment shader support.
