Writing Our Own Diffuse Lighting Shader

Lets explore how to build diffuse lighting onto our meshes. This is intended as somewhat of an introduction to some of the magic behind shaders.

There are two types of shaders you will typically create a in Unity. The first is the Standard [`Surface Sha…

Making a True Detective look! Controlling the Blending Stage in your Shader

Once you've got comfortable writing shaders in Unity you start to ask yourself how the graphics pipeline works under the hood, and if you are able to access it. In this post, I'm going to cover

Unity3D Particle Shaders – The simplest shader

In this series I will teach you how to write shaders for particle effects. This will be very VFX-centric so it will be probably much different than most of the tutorials which are covering mesh sha…

سلام اولش از Position Vector و Incoming Vector استفاده کرده که معادلش تو یونیتی به ترتیب World Position و View Direction هست

بعدش از ضرب خارجی بین این دو بردار استفاده کرده تا بردار عمودی رو بدست بیاره
در حالت عادی UV دوبعدی هست برای اینکه یک مختصات سه بعدی داشته باشیم یعنی UVW باید بین این دو برداری که داریم Cross Product بگیریم تا بردار عمودیش رو بدست بیاریم
