Detailed Description

A helper class to draw lines with a shiny, glossy texture.

No shaders used here, this is an old standard OpenGL technique.

Destructor.

It destructs.

Member Function Documentation

getLineTexture()

RefPtr< GlossyTexture > Wizt::GlossyLines::getLineTexture ( MemCore::Intercube &  CacheObject, VGLRenderContext &  Context, int  TextureUnit = 0  ) const

protected

Setup the line texture cached relative to the given object.

This may be a data field, or just the object's local State object.

What is then left to do is to active the texture by constructing a GlossyTexture::Render object. Code looks like this for instance:

RefPtr<GlossyTexture> LineTexture = getLineTexture(...);
{
GlossyTexture::Render LINERENDER( *LineTexture, Context.CameraSettings );
 
     glBegin(...);
     glTexCoord(...) // must contain the tangential vectors
     glEnd();
}

Note that tangential vectors \i must be defined during rendering for this glossy texture to work. They need to be specified as 3D texture coordinates.
