Detailed Description

This uses a derivative of Blinn's bump function to compute a 3-D looking image.

The elevation data can be from Grey Scale image or from a Dted file. This class can take one or two inputs. The First input is an elevation input that is used to compute a perturbed Normal which is used in a simple lambertian shading equation. The second input is some color source (Grey or RGB) that defines the diffuse color used within the illumination equation for each pixel. If the diffuse color input is not supplied then an all white color is used for the color. There are several adjustable parameters that can be set: 1) the Incident light vector described by the Azimuth and Elevation Angle, 2) the pixel scale used along the x and y direction, and 3) the partial derivative matrix used for the partial derivative computation along the x and y direction.

Some examples of good values:

If we are using dted 90 meters as input for shading then:
1) set pixel scale to 180.  Since the partials do 2*dx and 2*dy then
   the scale is 2*90meters = 180.
2) set azimuth angle to 45 and set elevation angle to 45 degrees.  Change
   them to see the effects.
3) use the following matrix -1 0 1
                            -1 0 1
                            -1 0 1
                               &
                             1  1  1
                             0  0  0
                            -1 -1 -1

   for the partials along x and y directions respectively.  These matrices

   (f(x+dx, y) - f(x-dx, y))/2*dx and
   (f(x, y+dy) - f(x, y-dy))/2*dy

   for an apprximate derivative about some point x, y

If we are using pixel intesity (1 - 255) then set the scales to around
100.

 Note: varying the scales will vary the smoothness/roughness of the surface
       Smaller the scale the rougher the surface will look.

The output of this source is always a 3-band 8-bit image.

Keywords:
  type:               ossimBumpShadeTileSource
  azimuth_angle:      45.000000000000000
  elevation_angle:    45.000000000000000
  scale_per_pixel_x:  180.000000000000000  // this is the 2*dx defined above
  scale_per_pixel_y:  180.000000000000000  // this is the 2*dy defined above

  the next set of keywords are optional and the default is as defined above.
  these define the matrix.

A typical chain would look something like this:

OrthoMosaicOfElevation–>Normals–>Renderer–>|
                                              |–> BumpShade–>Output 
ColorSource--------------------—>Renderer–>|

NOTES:

1) "Normals" is an ossimImageToPlaneNormalFilter class

2) The bump map input source is used to bump or shade the input color
source.  The input color source currently must be a 1 or 3 band
image.  Note that the output of this source is always
3 bands (r, g, b).

3) If no color source (2nd input layer) is present the r,g,b values will be
used.  The method setRgbColorSource can be used to control this.

Method to get a tile.

Parameters

result The tile to stuff. Note The requested rectangle in full image space and bands should be set in the result tile prior to passing. This is the default implementation that is not thread-friendly as it uses the object's tile then simply copies its buffer to the provided tile. Eventually, all image sources should override this method.

Returns: true on success false on error. If return is false, result is undefined so caller should handle appropriately with makeBlank or whatever.

Note: Derived classes should override this method to most efficiently stuff result.

◆ setRgbColorSource()

void ossimBumpShadeTileSource::setRgbColorSource	(	ossim_uint8	r,

Set the red, green and blue color source values.

This sets the rgb value used when no second layer is present.

The default is: r = 255, g = 255, b = 255

Parameters

r	red
g	green
b	blue
