Detailed Description#

A volume rendered object is a box with a 3D texture. Three slice planes are supported for the volume, one along each main axis of the volume.

Rendering volume objects is very performance intensive, especially when the volume is largely transparent, as the contents of the volume are ray-traced. The performance scales nearly linearly with the amount of pixels that the volume occupies on the screen, so showing the volume in a smaller view or limiting the zoom level of the graph are easy ways to improve performance. Similarly, the volume texture dimensions have a large impact on performance. If the frame rate is more important than pixel-perfect rendering of the volume contents, consider turning the high definition shader off by setting the useHighDefShader property to false.

Note

Volumetric objects are only supported with orthographic projection.

Note

Volumetric objects utilize 3D textures, which are not supported in OpenGL ES2 environments.

property PᅟySide6.QtDataVisualization.QCustom3DVolume.alphaMultiplier: float#

This property holds The value that the alpha value of every texel of the volume texture is multiplied with at the render time..

This property can be used to introduce uniform transparency to the volume. If preserveOpacity is true, only texels with at least some transparency to begin with are affected, and fully opaque texels are not affected. The value must not be negative. Defaults to 1.0f.

Access functions:

setAlphaMultiplier (mult)
Signal alphaMultiplierChanged (mult)

property PᅟySide6.QtDataVisualization.QCustom3DVolume.colorTable#

This property holds The array containing the colors for indexed texture formats..

If the texture format is not indexed, this array is not used and can be empty.

Defaults to 0.

Access functions:

colorTable ()

Signal colorTableChanged ()

property PᅟySide6.QtDataVisualization.QCustom3DVolume.drawSliceFrames: bool#

This property holds Whether slice frames are drawn around the volume..

If this property value is true, the frames of slices indicated by slice index properties will be drawn around the volume. If it is false, no slice frames will be drawn.

Drawing slice frames is independent of drawing slices, so you can show the full volume and still draw the slice frames around it. This is useful when using renderSlice() to display the slices outside the graph itself.

Defaults to false.

property PᅟySide6.QtDataVisualization.QCustom3DVolume.drawSlices: bool#

This property holds Whether the specified slices are drawn instead of the full volume..

If this property value is true, the slices indicated by slice index properties will be drawn instead of the full volume. If it is false, the full volume will always be drawn. Defaults to false.

Note

The slices are always drawn along the item axes, so if the item is rotated, the slices are rotated as well.

Signal drawSlicesChanged (enabled)

property PᅟySide6.QtDataVisualization.QCustom3DVolume.preserveOpacity: bool#

This property holds Whether the alpha multiplier is applied to all texels..

If this property value is true, alphaMultiplier is only applied to texels that already have some transparency. If it is false, the multiplier is applied to the alpha value of all texels. Defaults to true.

property PᅟySide6.QtDataVisualization.QCustom3DVolume.textureData: QList#

This property holds The array containing the texture data in the format specified by textureFormat ..

The size of this array must be at least (textureDataWidth * textureHeight * textureDepth * texture format color depth in bytes).

A 3D texture is defined by a stack of 2D subtextures. Each subtexture must be of identical size (textureDataWidth * textureHeight), and the depth of the stack is defined by the textureDepth property. The data in each 2D texture is identical to a QImage data with the same format, so QImage::bits() can be used to supply the data for each subtexture.

Ownership of the new array transfers to the QCustom3DVolume instance. If another array is set, the previous array is deleted. If the same array is set again, it is assumed that the array contents have been changed and the graph rendering is triggered.

Note

Each x-dimension line of the data needs to be 32-bit aligned. If textureFormat is Format_Indexed8 and the textureWidth value is not divisible by four, padding bytes might need to be added to each x-dimension line of the data. The textureDataWidth() function returns the padded byte count. The padding bytes should indicate a fully transparent color to avoid rendering artifacts.

Defaults to 0.

property PᅟySide6.QtDataVisualization.QCustom3DVolume.textureHeight: int#

property PᅟySide6.QtDataVisualization.QCustom3DVolume.textureWidth: int#

Defaults to 0.

Note

Access functions:

setTextureWidth (value)
Signal textureWidthChanged (value)

property PᅟySide6.QtDataVisualization.QCustom3DVolume.useHighDefShader: bool#

This property holds Whether a high or low definition shader is used to render the volume..

If this property value is true, a high definition shader is used. If it is false, a low definition shader is used.

The high definition shader guarantees that every visible texel of the volume texture is sampled when the volume is rendered. The low definition shader renders only a rough approximation of the volume contents, but at a much higher frame rate. The low definition shader does not guarantee that every texel of the volume texture is sampled, so there may be flickering if the volume contains distinct thin features.

Note

This value does not affect the level of detail when rendering the slices of the volume.

Defaults to true.

See also

textureData

PySide6.QtDataVisualization.QCustom3DVolume.setSubTextureData(axis, index, image)#

Parameters:

axis – Axis
index – int
image – PySide6.QtGui.QImage

Sets a single 2D subtexture of the 3D texture along the specified axis of the volume. The index parameter specifies the subtexture to set. The source image must be in the format specified by the textureFormat property if textureFormat is indexed. If textureFormat is Format_ARGB32 , the image is converted to that format. The image must have the size of the cross-section of the volume texture along the specified axis. The orientation of the image should correspond to the orientation of the slice image produced by renderSlice() method along the same axis.

Note

Each x-dimension line of the data needs to be 32-bit aligned when targeting the y-axis or z-axis. If textureFormat is Format_Indexed8 and the textureWidth value is not divisible by four, padding bytes might need to be added to each x-dimension line of the image to properly align it. The padding bytes should indicate a fully transparent color to avoid rendering artifacts. It is not guaranteed that QImage will do this automatically.

textureData renderSlice()

PySide6.QtDataVisualization.QCustom3DVolume.setSubTextureData(axis, index, data)

Parameters:

axis – Axis
index – int
data – str

Sets a single 2D subtexture of the 3D texture along the specified axis of the volume. The index parameter specifies the subtexture to set.

The data is expected to be ordered similarly to the data in images produced by the renderSlice() method along the same axis.

Note

Each x-dimension line of the data needs to be 32-bit aligned when targeting the y-axis or z-axis. If textureFormat is Format_Indexed8 and the textureWidth value is not divisible by four, padding bytes might need to be added to each x-dimension line of the data to properly align it. The padding bytes should indicate a fully transparent color to avoid rendering artifacts.
