问题描述
我正在3D世界中生成许多球体来表示对象，并且当我在黑色背景下工作时，我希望球体周围有一点辉光，我读到可以用着色器完成，但是需要更多指导，例如如何制作着色器以及将着色器放置在何处，我们将不胜感激.
Hi I'm generating lots of spheres in a 3D world to represent objects and as I'm working with a black background I want the spheres to have a little glow around them, I read that It can be done with shaders but need a little more guindance, for example how to make the shader and where to put it, any help will be appreciated.

它在对象周围创建边框并发出光晕效果.这是着色器，但您应该观看视频以进行学习(并为他们提供一个视图的功劳):
it creates a rim around the object and a glow effect. Here is the shader but you should watch the video for learning purpose (and to give them that one view count for credit):
Shader "Custom/GlowShader"
{
Properties
{
_ColorTint("Color Tint", Color) = (1, 1, 1, 1)
_MainTex("Base (RGB)", 2D) = "white" {}
_BumpMap("Normal Map", 2D) = "bump" {}
_RimColor("Rim Color", Color) = (1, 1, 1, 1)
_RimPower("Rim Power", Range(1.0, 6.0)) = 3.0
}
SubShader {
Tags { "RenderType"="Opaque" }
CGPROGRAM
#pragma surface surf Lambert
struct Input {
float4 color : Color;
float2 uv_MainTex;
float2 uv_BumpMap;
float3 viewDir;
};
float4 _ColorTint;
sampler2D _MainTex;
sampler2D _BumpMap;
float4 _RimColor;
float _RimPower;
void surf (Input IN, inout SurfaceOutput o)
{
IN.color = _ColorTint;
o.Albedo = tex2D (_MainTex, IN.uv_MainTex).rgb * IN.color;
o.Normal = UnpackNormal(tex2D(_BumpMap,IN.uv_BumpMap));
half rim = 1.0 - saturate(dot(normalize(IN.viewDir), o.Normal));
o.Emission = _RimColor.rgb * pow(rim, _RimPower);
}
ENDCG
}
FallBack "Diffuse"
}
