Classes
struct	GridParams
	GridParams is where you define the parameters of the volume grid, independently from the display. More...
struct	GridGPUParams
	This structure contains the GPU data of the volume that lives as the DisplayParams::mGridGPUParams member so we don't recompute all of this each frame. More...
struct	DisplayParams
	The parameters set for the display of the volume grid in the viewport. More...

Namespaces
namespace	MaxSDK
namespace	MaxSDK::Graphics
namespace	MaxSDK::Graphics::ViewportVolumeDisplay
	Volume Display functions for 3ds Max's viewport This is a set of functions for an Object plug-in to support a volume display in the viewport Link with MaxGraphics.lib when using this header.

Enumerations
enum class	DisplayType {   BoundingBox , Voxels , Volume , Wireframe ,   Iterations , Gradient , Octree , LastValue = Octree }
	The type of display for the volume. More...
enum class	GridType { Float16 , Float32 , LastValue = Float32 }
	The type of grid for this volume, there is one grid displayed per volume. More...
enum class	GridColorType {   Color , GradientMap , BlackBody , TurboRainbow ,   LastValue = TurboRainbow }
	The type of algorithm used to set color on the volume grid. More...
enum class	NormalizationType { None , Automatic , ManualRange , LastValue = ManualRange }
	We can normalize the volume grid data when providing a Float16 or Float32 grid. More...
enum class	SliceAxis {   Off , X , Y , Z ,   LastValue = Z }
	Slice axis is used to display only a part of the volume, a slice of it on a given axis at a given position and thickness. More...

Functions
MaxGraphicsObjectAPI bool	ComputeGridGPUParams (const GridParams &inGridParams, GridGPUParams &outGridGPUParams)
	This function is used to compute the GridGPUParams (GPU compliant data) information from the GridParams used by the display parameters, the output GridGPUParams is the DisplayParams::mGridGPUParams member of an instance of the DisplayParams structure stored locally in your plug-in so we don't recompute this data each frame.
MaxGraphicsObjectAPI bool	UpdatePerNodeItems (const MaxSDK::Graphics::UpdateDisplayContext &updateDisplayContext, MaxSDK::Graphics::UpdateNodeContext &nodeContext, MaxSDK::Graphics::IRenderItemContainer &targetRenderItemContainer, const DisplayParams &volumeDisplayParams)
	This function is used to let the volume API do everything for you to display the volume correctly from your plug-in method IObjectDisplay2::UpdatePerNodeItems.
MaxGraphicsObjectAPI int	HitTest (TimeValue t, INode *inode, int type, int crossing, int flags, IPoint2 *p, ViewExp *vpt, const DisplayParams &volumeDisplayParams)
	This function is used to let the volume API do the hit testing of the volume when the user wants to select a volume in a viewport.
