Hi Nie,
Hi all,
I am now working with osg::viewer for 3D model rendering.
As shown in the following sample image, for a single object, is it possible
to render in gradation color along a random direction(now it is along the
arrow).
Although it is only divided into 5 colors in the sample image, continuous color
is also acceptable.
Can I achieve this by adjust the parameter of the model( material or lighting)?
Or I have to write new a osg::viewer::frame() function?
If anyone knows how to complete this idea, I am looking forward for your answer.
If you need continuous coloring and your geometry is a cube, simply set
the vertex colors appropriate. Another option without touching the
geometry at all is to assign the color in the vertex shader based on the
desired vertex coordinates (i.e. red = vertex_z)
Third option is to use a texture, and again without modification you can
use built in texture coordinate generation in object_space
Cheers
Sebastian
