    Hi,

    Device detection is the first step in performing content adaptation. They want to use some type of browser detection script, it is a simple script which will detect most mobile browsers. Thanks a lot...

    Thanks, this is a great list. I’m now following around half the folks I’ve commented on – so for me this has been a double win – the comment and the further reading material that helps me and my blog!

    Firstly, I would like to thank you for putting emphasis on how relevancy plays a big role in blog commenting as I had this going in my mind for a long time. And secondly, thanks for sharing the list of all the websites. I would like to request you to please share for Sports categories as well. Thanks for all the useful insights.

tex2D vs. tex2Dproj

texCoord(  texX, texY, texZ , texW ) means texture coordinate after transforming from the texture matrix [ position goes through world, view, projection, and texture ].


We can use texCoord to fetch texture:
1.  float4 color = tex2D( sampler,  float2( texX / texW, texY/texW );
2.  float4 color = tex2Dporj( sampler, float4( texX, texY, texZ, texW ) );

The top-two methods will have the same result. Because tex2Dproj operator supports divide w in its interface.

Fast subsurface scattering

Image
Fig.1 - Fast Subsurface scattering of Stanford Bunny
Based on the implementation of three.js. It provides a cheap, fast, and convincing approach to do ray-tracing in translucent surfaces. It refers the sharing in GDC 2011 [1], and the approach is used by Frostbite 2 and Unity engines [1][2][3]. Traditionally, when a ray intersects with surfaces, it needs to calculate the bouncing result after intersections. Materials can be divided into three types roughly. Opaque, lights can't go through its geometry and the ray will be bounced back. Transparency, the ray passes and allow it through the surface totally, it probably would loose a little energy after leaving. Translucency, the ray after entering the surface will be bounced internally like below Fig. 2.

Fig.2 - BSSRDF [1]
In the case of translucency, we have several subsurface scattering approaches to solve our problem. When a light is traveling inside the shape, that needs to consider the diffuse value influence according the vary…

Physically-Based Rendering in WebGL

Image
According to the image from Physically Based Shading At Disney as below, the left is the real chrome, the middle is PBR approach, and the right is Blinn-Phong. We can find PBR is more closer to the real case, and the difference part is the specular lighting part.


Blinn-Phong

The most important part of specular term in Blinn-Phong is it uses half-vector instead of using dot(lightDir, normalDir) to avoid the traditional Phong lighting model hard shape problem.

vec3 BRDF_Specular_BlinnPhong( vec3 lightDir, vec3 viewDir, vec3 normal, vec3 specularColor, float shininess ) { vec3 halfDir = normalize( lightDir + viewDir ); float dotNH = saturate( dot( normal, halfDir ) ); float dotLH = saturate( dot( lightDir, halfDir ) ); vec3 F = F_Schlick( specularColor, dotLH ); float G = G_BlinnPhong_Implicit( ); float D = D_BlinnPhong( shininess, dotNH ); return F * ( G * D ); }
