Volume Renderer is a volume rendering program based on VTK, CTK and Qt.

Improvements in this repository（Compared with volume-renderer）

• Interaction: Realtime adjustment, for Listener(Observer) on the rightside tool box.
• Renderer: SmartRenderer support.
• Format: slc format support.
• UI: FPS calculation.

File support

• slc format

Renderer Support (Hot switch）

• vtkSlicerGPURayCastVolumeMapper( from Slicer https://www.slicer.org/ )
• vtkGPUVolumeRayCastMapper
• vtkSmartVolumeMapper (Default. Recommended. Microsoft Remote Desktop can downgrade OpenGL to 1.1 and it can switch to CPU)

Transfer Function Interaction

• Drag a point
• Delete a point
• Add a point
• Change RGB color of a demarcation point
• Digital setting mode supported

Framerate Display

• When the FPS is greater than 60 ,the color is black; otherwise red.

Others

Advanced interpolation, shade and material settings.

1. Open executable/VolumeRenderer/VolumeRenderer.exe in Windows (64bit).
2. Click "Open" and select a slc file (vm_foot.slc).
3. Have fun.
