QHeightMapSurfaceDataProxy takes care of the processing of height map data related to surfaces. It provides the visualization of a height map as a surface plot.
For more complete description, see QHeightMapSurfaceDataProxy .

|
autoScaleY : real |
Scale height values to Y-axis. Defaults to
false
. When this property is set to
true
, the height values are scaled to fit on the Y-axis between
minYValue
and
maxYValue
.
|
heightMapFile : string |
A file with a height map image to be visualized. Setting this property replaces current data with height map data.
There are several formats the image file can be given in, but if it is not in a directly usable format, a conversion is made.
注意： If the result seems wrong, the automatic conversion failed and you should try converting the image yourself before setting it. Preferred format is QImage::Format_RGB32 in grayscale.
The height of the image is read from the red component of the pixels if the image is in grayscale. Otherwise, it is an average calculated from the red, green, and blue components of the pixels. Using grayscale images may improve data conversion speed for large images.
Since height maps do not contain values for X or Z axes, these values need to be given separately using the minXValue , maxXValue , minZValue ，和 maxZValue properties. The X-value corresponds to the image's horizontal direction, and the Z-value to the vertical. Setting any of these properties triggers an asynchronous re-resolution of any existing height map.
Not recommended formats: all mono formats (for example QImage::Format_Mono ).
|
maxXValue : real |
The maximum X value for the generated surface points. Defaults to
10.0
. When setting this property the corresponding minimum value is adjusted if necessary, to ensure that the range remains valid.
|
maxYValue : real |
The maximum Y value for the generated surface points. Defaults to
10.0
. When setting this property the corresponding minimum value is adjusted if necessary, to ensure that the range remains valid.
|
maxZValue : real |
The maximum Z value for the generated surface points. Defaults to
10.0
. When setting this property the corresponding minimum value is adjusted if necessary, to ensure that the range remains valid.
|
minXValue : real |
The minimum X value for the generated surface points. Defaults to
0.0
. When setting this property the corresponding maximum value is adjusted if necessary, to ensure that the range remains valid.
|
minYValue : real |
The minimum Y value for the generated surface points. Defaults to
0.0
. When setting this property the corresponding maximum value is adjusted if necessary, to ensure that the range remains valid.
|
minZValue : real |
The minimum Z value for the generated surface points. Defaults to
0.0
. When setting this property the corresponding maximum value is adjusted if necessary, to ensure that the range remains valid.
