Hey, we meet again.
I hope to come back in a while and post something in progress about my RealKo Engine.
Okay, this time I will show you the real stuff of airplane applied with diffuse/specular/normal mapp.

I have found out by myself, get the feeling that only the diffuse map is not enough in this modern day. Every models, if possible, should have all the basic textureset that is diffuse/specular/normal as the base. For other maps, it’s up to the implementation. That textureset can enhance the visual-feeling of the material for each of the different model in the game in the great amount. By combining it with the deferred shading, you can get most the visual quality (along with performance at the same time).

For what I gonna show you now is the demo scene, consists of 2 boeing classes which are Boeing 100 with master texture, and Boeing 400 with Thai Airways texture. Also with the preset 3 lights which are 1 directional light (sun light which point straight downward), and 2 pointlight which one of them is located near the airport tower, and another is located infront the tower on the runway-floor, both of point light just be a bit higher from the ground.
Note that one of the point light has Coral color, another has white color.

The demo scene demonstrates the effect of light, particles scene integrated with deferred shading process (in fact it’s just drawed after the deferred shading result), textureset applied for model (boeing in this case). And you can see other minor features by yourself in the gallery below.

Before I show you the gallery of this demo scene, let’s see the textureset applied with the airplane itself first. Just to get some feeling of how important the diffuse/specular/normal can enhance our scene and overall visualization.

Textureset applied with airplane

Diffuse Map

Specular Map

Normal Map

Those are textures used and applied with the airplane model.

Note: The reason I tell my artist to do the gray scale format for specular map for me is that, my shader code will get the data out from the specular map in one whole scalar value, not color. So by choosing the gray scale, we can just read the red channel of the map and that’s it, just furthur apply with the lighting algorithm then we’re done.

See my excerpt shader code for that part.

if(specularTextureEnabled)
{
output.Color.a = tex2D(specularSampler, input.TexCoords).r * specularIntensity;
}
else
{
output.Color.a = specularIntensity;
}

Let’s see the result of all we are talking about.

I also included a couple of images that aren’t applied with textureset.

Okay, it’s late now haaah!!
Until next time my friends.
