DESCRIPTION

vtkThresholdTextureCoords is a filter that generates texture coordinates for any input dataset type given a threshold criterion. The criterion can take three forms: 1) greater than a particular value (ThresholdByUpper()); 2) less than a particular value (ThresholdByLower(); or 3) between two values (ThresholdBetween(). If the threshold criterion is satisfied, the "in" texture coordinate will be set (this can be specified by the user). If the threshold criterion is not satisfied the "out" is set.

CAVEATS

There is a texture map - texThres.vtk - that can be used in conjunction with this filter. This map defines a "transparent" region for texture coordinates 0<=r<0.5, and an
opaque full intensity map for texture coordinates 0.5

SUMMARY

void SetTextureDimension(int)
Set the desired dimension of the texture map.

void SetInTextureCoord(float, float, float)
void SetInTextureCoord(float *)
Set the texture coordinate value for point satisfying threshold criterion.

void SetOutTextureCoord(float, float, float)
void SetOutTextureCoord(float *)
Set the texture coordinate value for point NOT satisfying threshold criterion.

void ThresholdByLower(float lower)
Criterion is cells whose scalars are less than lower threshold.

void ThresholdByUpper(float upper)
Criterion is cells whose scalars are less than upper threshold.

void ThresholdBetween(float lower, float upper)
Criterion is cells whose scalars are between lower and upper thresholds.
