DESCRIPTION
|
|
===========
|
|
|
|
``dxPtexViewer`` is a stand-alone application that showcases advanced HDR shading
|
|
with color, displacement, occlusion and specular ptex maps. Multiple controls
|
|
are available to experiment with the algorithms.

OPTIONS
|
|
=======
|
|
|
|
**-e** *environment map*
|
|
A low dynamic range spherical environment map used as a background. Ideally,
|
|
a color-normalized version of the HDR light probe.
|
|
|
|
**-d** *HDR diffuse map*
|
|
An HDR file containing a diffuse environment map (typically they are low
|
|
resolution blurry hemispherical convolutions of the environment light probe).
|
|
|
|
**-s** *environment map*
|
|
An HDR file containing a specular environment map.
|
|
|
|
**--disp** *displacement scale*
|
|
A scalar multiplier for the shader displacement values.
|
|
|
|
**-y**
|
|
Swap Z-up geometry to Y-UP.
|
|
|
|
**-l** *isolation level*
|
|
Select the desired isolation level of adaptive feature isolation. This can be
|
|
useful when trying to load large pieces of geometry.
|
|
|
|
*ptex color file*
|
|
A ptex file containing RGB channels read as material albedo color.
|
|
|
|
*ptex displacement file*
|
|
A single-channel ptex file (preferrably float precision) containing the
|
|
displacement values.
|
|
|
|
*ptex occlusion file*
|
|
A single-channel ptex file (preferrably 8 bits precision) containing a
|
|
pre-computed ambient occlusion signal.
|
|
|
|
*ptex specular file*
|
|
A single-channel ptex file (preferrably 8 bits precision) applied to modulate
|
|
the specular reflectance of the material
|
|
|
|
*objfile(s)*
|
|
A sequence of obj files used as an animation loop (the topology has to match
|
|
the data contained in all the ptex files !)
