Hi All,
based on osgParametric-example i try to get a vertexshader to update a
Uniform from a sum of perVertex-operations. I tried to read the result back
into the application. While there is no problem to "feed" the VertexShader
with updated values from a UniformCallback, i can't update a uniform inside
a shader and use the value per frame in the osg-application.
Is it possible to assign/increment a Uniform-value inside of a vertex-shader
and read the result per frame in the osg-application? Maybe there are some
examples showing how to solve this ?
Thanks for infos.
Markus
