05 Basic Programming: Structs - HLSL Shader Creation 1 - HLSL Shader Fundamentals

CH 05: Basic Programming: Structs explains what data structs are and how they're used in HLSL.

In the first of our Advanced series on HLSL Shader writing within 3dsmax, Ben Cloward will give you an understanding of what an HLSL shader is, how a shader can be created with free software, edited, and then displayed within 3dsmax. Fundamental programming concepts such as Data Types, Structs and Functions will be covered. How to create a shader GUI, the basic framework of an HLSL FX shader and much much more. By the close of the series, Ben will have you writing your own basic HLSL shaders.

This series is an ideal introduction to the world of HLSL shader writing for real-time GPU based shaders. An understanding of basic programming concepts and 3D math is useful.

This video series was first published in 2007. Although some of the material is out of date, almost all of the principles taught here are still valuable to learn and understand as foundation to learning to write shaders.

could you tell me what's mean of “ : POSITION ” in the struct？
