Classes
class	LineDrawingRenderingMode
	The abstract interface for a "Line Drawing" sytle rendering mode. More...
class	LineDrawingRenderingMode::LineDrawingStripCB
class	LineDrawingVprogFprogNoSSDMode
	A rendering mode for the "Line Drawing" rendering style that uses OpenGL ARB vertex and fragment programs without screen space derivatives (multitexturing is used instead). More...

void maketexture (  double  width, double  fadeout )

Create a texture with a black line of the given width. Call this after binding a valid texture object. That texture object will have its image data replaced with a 1024x1024 pixel image containing a black line of width width. This function automatically computes mipmaps and turns on trilinear filtering (i.e. minification filter GL_LINEAR_MIPMAP_LINEAR). Definition at line 1115 of file line_drawing.C.
