I've heard the term "Shader" many times and I havent put too many attention to it. But on the latest Steam Update, Valve mentions the capacity for us to create our own shaders. So if anyone can answer me, What are Shaders?

brett, you are not being helpful.. most of us have had this happen a few times, and it loses its uniqueness after the first 1/2 dozen or so. [addsig]

Shaders are unique ways of representing textures?

So proper cellshade can be done?

Take a look at it this way: you put textures on your brushes, but want to add an effect. The floor has to reflect certain things, or it has to look wet and slippery ... that's where shaders come in. They add certain effects to textures.


quote:
A procedural plug-in, loaded into the mental ray rendering software in the form of a shader library, that defines the surfaces of objects in a certain way. Originally, shaders computed only surface shading, but the term stuck as new types of shaders were invented that had nothing to do with shading. Shaders are grouped as the following types: contour, displacement, environment, lens, light, light photon, output, photon, shadow, surface, texture, volume, and volume photon.

A shader defines the final surface properties of an object. For example, a shader can define the color, reflectivity, and transluscency of a surface.

I get it. It's like when you have a texture for clear glass and one for darkened glass, both are trnaslucent but the dark glass reflects more than the clear one. In the past, on the Quake engine they used to simulate the effect of water, sludge and lava using movement on the texture.

Thanks for the info Forceflow.

Source SDK FAQ says shaders define the equations used to work out the colour of each pixel. So, this is a coding thing... but that allows for some cool modding capabilities, like cel shading, and... other cool stuff i cant think of at the moment. [addsig]
