View Full Version : What's meant by shading

Dear Friends
I have created a surface from a 2D profile by revolving the profile points with respect to x-axis by intermittently from 0 to 360 degrees. And I get a full 360 degree surface of revolutions. Now I am setting the color as red.
I am now asked to shade the model. What does it mean by shading. exactly what i have to do now. Can anyone explain shading thanks lot. sujan

There's no way to know what was meant by "shading" without some form of context for the discussion. It could mean a lot of things.

When someone refers to shading, it usually refers to the use of a surface shader which is a program that ranges over scene objects to calculate the color of each pixel based on how light is interacting with the surface. It's sort of analogous to a material in most 3D modelling programs.

You can also use shaders to calculate things other than colour, such as how much a surface is displaced or how to map a texture to the surface.

That's pretty much how I understand shading. Others might be able to elaborate or correct me. :)
