Contour Shaders

The contour shader library contains a number of contour shaders that are useful for rendering cartoon-type images. For details on contour rendering, see chapter contour.

Before any shader in the contour shader library can be used, it must be attached to the mental ray rendering software using a statement link "contour.so", and the shaders must be declared with the statement $include <contour.mi>. Declarations are given in mi format, as described in chapter shader on page shader. Here is the summary:

group	shader	page
Contour store	contour_store_function	contour_store_function
	contour_store_function_simple	contour_store_function_simple

Contour contrast	contour_contrast_function_levels	contour_contrast_functionlevels
	contour_contrast_function_simple	contour_contrast_function_simple

Contour shader	contour_shader_simple	contour_shader_simple
	contour_shader_curvature	contour_shader_curvature
	contour_shader_widthfromcolor	contour_shader_widthfromcolor
	contour_shader_factorcolor	contour_shader_factorcolor
	contour_shader_depthfade	contour_shader_depthfade
	contour_shader_framefade	contour_shader_framefade
	contour_shader_widthfromlight	contour_shader_widthfromlight
	contour_shader_widthfromlightdir	contour_shader_widthfromlightdir
	contour_shader_layerthinner	contour_shader_layerthinner
	contour_shader_combi	contour_shader_combi

Contour output	contour_only	contour_only
	contour_composite	contour_composite
	contour_ps	contour_ps
